-.Sh DESCRIPTION
-The
-.Fn _exit
-system call
-terminates a process with the following consequences:
-.Bl -bullet
-.It
-All of the descriptors open in the calling process are closed.
-This may entail delays, for example, waiting for output to drain;
-a process in this state may not be killed, as it is already dying.
-.It
-If the parent process of the calling process has an outstanding
-.Xr wait 2
-call
-or catches the
-.Dv SIGCHLD
-signal,
-it is notified of the calling process's termination and
-the
-.Fa status
-is set as defined by
-.Xr wait 2 .
-.It
-The parent process-ID of all of the calling process's existing child
-processes are set to 1; the initialization process
-inherits each of these processes
-(see
-.Xr init 8
-and the
-.Sx DEFINITIONS
-section of
-.Xr intro 2 ) .
-.It
-If the termination of the process causes any process group
-to become orphaned (usually because the parents of all members
-of the group have now exited; see
-.Dq orphaned process group
-in
-.Xr intro 2 ) ,
-and if any member of the orphaned group is stopped,
-the
-.Dv SIGHUP
-signal and the
-.Dv SIGCONT
-signal are sent to all members of the newly-orphaned process group.
-.It
-If the process is a controlling process (see
-.Xr intro 2 ) ,
-the
-.Dv SIGHUP
-signal is sent to the foreground process group of the controlling terminal,
-and all current access to the controlling terminal is revoked.
-.El
-.Pp
-Most C programs call the library routine
-.Xr exit 3 ,
-which flushes buffers, closes streams, unlinks temporary files, etc.,
-before
-calling
-.Fn _exit .

-.Dt ACCEPT 2
-.Os
-.Sh NAME
-.Nm accept
-.Nd accept a connection on a socket
-.Sh LIBRARY
-.Lb libc
-.Sh SYNOPSIS
-.In sys/types.h
-.In sys/socket.h
-.Ft int
-.Fn accept "int s" "struct sockaddr * restrict addr" "socklen_t * restrict addrlen"
-.Sh DESCRIPTION
-The argument
-.Fa s
-is a socket that has been created with
-.Xr socket 2 ,
-bound to an address with
-.Xr bind 2 ,
-and is listening for connections after a
-.Xr listen 2 .
-The
-.Fn accept
-system call extracts the first connection request on the
-queue of pending connections, creates a new socket,
-and allocates a new file descriptor for the socket which
-inherits the state of the
-.Dv O_NONBLOCK
-property from the original socket
-.Fa s .
-.Pp
-If no pending connections are
-present on the queue, and the original socket
-is not marked as non-blocking,
-.Fn accept
-blocks the caller until a connection is present.
-If the original socket
-is marked non-blocking and no pending
-connections are present on the queue,
-.Fn accept
-returns an error as described below.
-The accepted socket
-may not be used
-to accept more connections.
-The original socket
-.Fa s
-remains open.
-.Pp
-The argument
-.Fa addr
-is a result argument that is filled-in with
-the address of the connecting entity,
-as known to the communications layer.
-The exact format of the
-.Fa addr
-argument is determined by the domain in which the communication
-is occurring.
-A null pointer may be specified for
-.Fa addr
-if the address information is not desired;
-in this case,
-.Fa addrlen
-is not used and should also be null.
-Otherwise, the
-.Fa addrlen
-argument
-is a value-result argument; it should initially contain the
-amount of space pointed to by
-.Fa addr ;
-on return it will contain the actual length (in bytes) of the
-address returned.
-This call
-is used with connection-based socket types, currently with
-.Dv SOCK_STREAM .
-.Pp
-It is possible to
-.Xr select 2
-a socket for the purposes of doing an
-.Fn accept
-by selecting it for read.
-.Pp
-For certain protocols which require an explicit confirmation,
-such as
-.Tn ISO
-or
-.Tn DATAKIT ,
-.Fn accept
-can be thought of
-as merely dequeueing the next connection
-request and not implying confirmation.
-Confirmation can be implied by a normal read or write on the new
-file descriptor, and rejection can be implied by closing the
-new socket.
-.Pp
-For some applications, performance may be enhanced by using an
-.Xr accept_filter 9
-to pre-process incoming connections.
-.Pp
-Portable programs should not rely on the
-.Dv O_NONBLOCK
-property being inherited.
-.Sh RETURN VALUES
-The call returns \-1 on error.
-If it succeeds, it returns a non-negative
-integer that is a descriptor for the accepted socket.
-.Sh ERRORS
-The
-.Fn accept
-system call will fail if:
-.Bl -tag -width Er
-.It Bq Er EBADF
-The descriptor is invalid.
-.It Bq Er EINTR
-The
-.Fn accept
-operation was interrupted.

-.Ft int
-.Fn faccessat "int fd" "const char *path" "int mode" "int flag"
-.Sh DESCRIPTION
-The
-.Fn access
-and
-.Fn eaccess
-system calls check the accessibility of the
-file named by
-the
-.Fa path
-argument
-for the access permissions indicated by
-the
-.Fa mode
-argument.
-The value of
-.Fa mode
-is either the bitwise-inclusive OR of the access permissions to be
-checked
-.Dv ( R_OK
-for read permission,
-.Dv W_OK
-for write permission, and
-.Dv X_OK
-for execute/search permission),
-or the existence test
-.Pq Dv F_OK .
-.Pp
-For additional information, see the
-.Sx "File Access Permission"
-section of
-.Xr intro 2 .
-.Pp
-The
-.Fn eaccess
-system call uses
-the effective user ID and the group access list
-to authorize the request;
-the
-.Fn access
-system call uses
-the real user ID in place of the effective user ID,
-the real group ID in place of the effective group ID,
-and the rest of the group access list.
-.Pp
-The
-.Fn faccessat
-system call is equivalent to
-.Fn access
-except in the case where
-.Fa path
-specifies a relative path.
-In this case the file whose accessibility is to be determined is
-located relative to the directory associated with the file descriptor
-.Fa fd
-instead of the current working directory.
-If
-.Fn faccessat
-is passed the special value
-.Dv AT_FDCWD
-in the
-.Fa fd
-parameter, the current working directory is used and the behavior is
-identical to a call to
-.Fn access .
-Values for
-.Fa flag
-are constructed by a bitwise-inclusive OR of flags from the following
-list, defined in
-.In fcntl.h :
-.Bl -tag -width indent
-.It Dv AT_EACCESS
-The checks for accessibility are performed using the effective user and group
-IDs instead of the real user and group ID as required in a call to
-.Fn access .
-.El
-.Pp
-Even if a process's real or effective user has appropriate privileges
-and indicates success for
-.Dv X_OK ,
-the file may not actually have execute permission bits set.
-Likewise for
-.Dv R_OK
-and
-.Dv W_OK .
-.Sh RETURN VALUES
-.Rv -std
-.Sh ERRORS
-Access to the file is denied if:
-.Bl -tag -width Er
-.It Bq Er ENOTDIR
-A component of the path prefix is not a directory.
-.It Bq Er ENAMETOOLONG
-A component of a pathname exceeded 255 characters,
-or an entire path name exceeded 1023 characters.
-.It Bq Er ENOENT
-The named file does not exist.
-.It Bq Er ELOOP
-Too many symbolic links were encountered in translating the pathname.
-.It Bq Er EROFS
-Write access is requested for a file on a read-only file system.
-.It Bq Er ETXTBSY
-Write access is requested for a pure procedure (shared text)
-file presently being executed.
-.It Bq Er EACCES
-Permission bits of the file mode do not permit the requested
-access, or search permission is denied on a component of the
-path prefix.
-.It Bq Er EFAULT
-The
-.Fa path
-argument
-points outside the process's allocated address space.
-.It Bq Er EIO
-An I/O error occurred while reading from or writing to the file system.
-.El
-.Pp
-Also, the
-.Fn faccessat
-system call may fail if:
-.Bl -tag -width Er
-.It Bq Er EBADF
-The
-.Fa path
-argument does not specify an absolute path and the
-.Fa fd
-argument is
-neither
-.Dv AT_FDCWD
-nor a valid file descriptor.
-.It Bq Er EINVAL
-The value of the

-argument is not valid.
-.It Bq Er ENOTDIR

-.Sh SEE ALSO
-.Xr chmod 2 ,

-.Sh STANDARDS
-The

-The
-.Fn faccessat
-system call follows The Open Group Extended API Set 2 specification.
-.Sh HISTORY
-The
-.Fn access
-function appeared in

-The
-.Fn faccessat
-system call appeared in

-.Sh SECURITY CONSIDERATIONS
-The
-.Fn access
-system call
-is a potential security hole due to race conditions and
-should never be used.
-Set-user-ID and set-group-ID applications should restore the
-effective user or group ID,
-and perform actions directly rather than use
-.Fn access
-to simulate access checks for the real user or group ID.
-The
-.Fn eaccess
-system call
-likewise may be subject to races if used inappropriately.
-.Pp
-.Fn access
-remains useful for providing clues to users as to whether operations
-make sense for particular filesystem objects (e.g. 'delete' menu
-item only highlighted in a writable folder ... avoiding interpretation
-of the st_mode bits that the application might not understand --
-e.g. in the case of AFS).
-It also allows a cheaper file existence test than
-.Xr stat 2 .

-.Sh SYNOPSIS
-.In sys/time.h
-.Ft int
-.Fn adjtime "const struct timeval *delta" "struct timeval *olddelta"
-.Sh DESCRIPTION
-The
-.Fn adjtime
-system call
-makes small adjustments to the system time, as returned by
-.Xr gettimeofday 2 ,
-advancing or retarding it
-by the time specified by the timeval
-.Fa delta .
-If
-.Fa delta
-is negative, the clock is
-slowed down by incrementing it more slowly than normal until
-the correction is complete.
-If
-.Fa delta
-is positive, a larger increment than normal
-is used.
-The skew used to perform the correction is generally a fraction of one percent.
-Thus, the time is always
-a monotonically increasing function.
-A time correction from an earlier call to
-.Fn adjtime
-may not be finished when
-.Fn adjtime
-is called again.
-If
-.Fa olddelta
-is not a null pointer,
-the structure pointed to will contain, upon return, the
-number of microseconds still to be corrected
-from the earlier call.
-.Pp
-This call may be used by time servers that synchronize the clocks
-of computers in a local area network.
-Such time servers would slow down the clocks of some machines
-and speed up the clocks of others to bring them to the average network time.
-.Pp
-The

-.Dt AIO_READ 2
-.Os
-.Sh NAME
-.Nm aio_read
-.Nd asynchronous read from a file (REALTIME)
-.Sh LIBRARY
-.Lb libc
-.Sh SYNOPSIS
-.In aio.h
-.Ft int
-.Fn aio_read "struct aiocb *iocb"
-.Sh DESCRIPTION
-The
-.Fn aio_read
-system call allows the calling process to read
-.Fa iocb->aio_nbytes
-from the descriptor
-.Fa iocb->aio_fildes
-beginning at the offset
-.Fa iocb->aio_offset
-into the buffer pointed to by
-.Fa iocb->aio_buf .
-The call returns immediately after the read request has
-been enqueued to the descriptor; the read may or may not have
-completed at the time the call returns.
-.Pp
-If _POSIX_PRIORITIZED_IO is defined, and the descriptor supports it,
-then the enqueued operation is submitted at a priority equal to that
-of the calling process minus
-.Fa iocb->aio_reqprio .
-.Pp
-The
-.Fa iocb->aio_lio_opcode
-argument
-is ignored by the
-.Fn aio_read
-system call.
-.Pp
-The
-.Fa iocb
-pointer may be subsequently used as an argument to
-.Fn aio_return
-and
-.Fn aio_error
-in order to determine return or error status for the enqueued operation
-while it is in progress.
-.Pp
-If the request could not be enqueued (generally due to invalid arguments),
-then the call returns without having enqueued the request.
-.Pp
-If the request is successfully enqueued, the value of
-.Fa iocb->aio_offset
-can be modified during the request as context, so this value must
-not be referenced after the request is enqueued.
-.Sh RESTRICTIONS
-The Asynchronous I/O Control Block structure pointed to by
-.Fa iocb
-and the buffer that the
-.Fa iocb->aio_buf
-member of that structure references must remain valid until the
-operation has completed.
-For this reason, use of auto (stack) variables
-for these objects is discouraged.
-.Pp
-The asynchronous I/O control buffer
-.Fa iocb
-should be zeroed before the
-.Fn aio_read
-call to avoid passing bogus context information to the kernel.
-.Pp
-Modifications of the Asynchronous I/O Control Block structure or the
-buffer contents after the request has been enqueued, but before the
-request has completed, are not allowed.
-.Pp
-If the file offset in
-.Fa iocb->aio_offset
-is past the offset maximum for
-.Fa iocb->aio_fildes ,
-no I/O will occur.
-.Sh RETURN VALUES
-.Rv -std aio_read
-.Sh DIAGNOSTICS
-None.
-.Sh ERRORS
-The
-.Fn aio_read
-system call will fail if:
-.Bl -tag -width Er
-.It Bq Er EAGAIN
-The request was not queued because of system resource limitations.
-.It Bq Er ENOSYS
-The
-.Fn aio_read
-system call is not supported.
-.El
-.Pp
-The following conditions may be synchronously detected when the
-.Fn aio_read
-system call is made, or asynchronously, at any time thereafter.
-If they
-are detected at call time,
-.Fn aio_read
-returns -1 and sets
-.Va errno
-appropriately; otherwise the
-.Fn aio_return
-system call must be called, and will return -1, and
-.Fn aio_error
-must be called to determine the actual value that would have been
-returned in
-.Va errno .
-.Bl -tag -width Er
-.It Bq Er EBADF
-The
-.Fa iocb->aio_fildes
-argument
-is invalid.
-.It Bq Er EINVAL
-The offset
-.Fa iocb->aio_offset
-is not valid, the priority specified by
-.Fa iocb->aio_reqprio
-is not a valid priority, or the number of bytes specified by
-.Fa iocb->aio_nbytes
-is not valid.
-.It Bq Er EOVERFLOW
-The file is a regular file,
-.Fa iocb->aio_nbytes
-is greater than zero, the starting offset in
-.Fa iocb->aio_offset
-is before the end of the file, but is at or beyond the
-.Fa iocb->aio_fildes
-offset maximum.
-.El
-.Pp
-If the request is successfully enqueued, but subsequently cancelled
-or an error occurs, the value returned by the
-.Fn aio_return
-system call is per the
-.Xr read 2
-system call, and the value returned by the
-.Fn aio_error

-.Nd wait for the next completion of an aio request
-.Sh LIBRARY
-.Lb libc
-.Sh SYNOPSIS
-.In aio.h
-.Ft int
-.Fn aio_waitcomplete "struct aiocb **iocbp" "struct timespec *timeout"
-.Sh DESCRIPTION
-The
-.Fn aio_waitcomplete
-system call waits for completion of an asynchronous I/O request.
-Upon completion,
-.Fn aio_waitcomplete
-returns the result of the function and sets
-.Fa iocbp
-to point to the structure associated with the original request.
-If an asynchronous I/O request is completed before
-.Fn aio_waitcomplete
-is called, it returns immediately with the completed request.
-.Pp
-If
-.Fa timeout
-is a non-NULL pointer, it specifies a maximum interval to wait for a
-asynchronous I/O request to complete.
-If
-.Fa timeout
-is a NULL pointer,
-.Fn aio_waitcomplete
-waits indefinitely.
-To effect a poll, the
-.Fa timeout
-argument should be non-NULL, pointing to a zero-valued timeval structure.
-.Pp
-The
-.Fn aio_waitcomplete
-system call also serves the function of
-.Fn aio_return ,
-thus
-.Fn aio_return
-should not be called for the control block returned in
-.Fa iocbp .
-.Sh RETURN VALUES
-If an asynchronous I/O request has completed,
-.Fa iocbp
-is set to point to the control block passed with the original request,
-and the status is returned as described in
-.Xr read 2 ,
-.Xr write 2 ,
-or
-.Xr fsync 2 .
-On failure,
-.Fn aio_waitcomplete
-returns
-.Dv -1 ,
-sets iocbp to
-.Dv NULL
-and sets
-.Va errno
-to indicate the error condition.
-.Sh ERRORS
-The
-.Fn aio_waitcomplete
-system call fails if:
-.Bl -tag -width Er
-.It Bq Er EINVAL
-The specified time limit is invalid.
-.It Bq Er EAGAIN
-The process has not yet called
-.Fn aio_read
-or
-.Fn aio_write .
-.It Bq Er EINTR
-A signal was delivered before the timeout expired and before any
-asynchronous I/O requests completed.
-.It Bq Er EWOULDBLOCK
-.It Bq Er EINPROGRESS
-The specified time limit expired before any asynchronous I/O requests
-completed.

-.Dt AIO_WRITE 2
-.Os
-.Sh NAME
-.Nm aio_write
-.Nd asynchronous write to a file (REALTIME)
-.Sh LIBRARY
-.Lb libc
-.Sh SYNOPSIS
-.In aio.h
-.Ft int
-.Fn aio_write "struct aiocb *iocb"
-.Sh DESCRIPTION
-The
-.Fn aio_write
-system call allows the calling process to write
-.Fa iocb->aio_nbytes
-from the buffer pointed to by
-.Fa iocb->aio_buf
-to the descriptor
-.Fa iocb->aio_fildes .
-The call returns immediately after the write request has been enqueued
-to the descriptor; the write may or may not have completed at the time
-the call returns.
-If the request could not be enqueued, generally due
-to invalid arguments, the call returns without having enqueued the
-request.
-.Pp
-If
-.Dv O_APPEND
-is set for
-.Fa iocb->aio_fildes ,
-.Fn aio_write
-operations append to the file in the same order as the calls were
-made.
-If
-.Dv O_APPEND
-is not set for the file descriptor, the write operation will occur at
-the absolute position from the beginning of the file plus
-.Fa iocb->aio_offset .
-.Pp
-If
-.Dv _POSIX_PRIORITIZED_IO
-is defined, and the descriptor supports it, then the enqueued
-operation is submitted at a priority equal to that of the calling
-process minus
-.Fa iocb->aio_reqprio .
-.Pp
-The
-.Fa iocb
-pointer may be subsequently used as an argument to
-.Fn aio_return
-and
-.Fn aio_error
-in order to determine return or error status for the enqueued operation
-while it is in progress.
-.Pp
-If the request is successfully enqueued, the value of
-.Fa iocb->aio_offset
-can be modified during the request as context, so this value must not
-be referenced after the request is enqueued.
-.Sh RESTRICTIONS
-The Asynchronous I/O Control Block structure pointed to by
-.Fa iocb
-and the buffer that the
-.Fa iocb->aio_buf
-member of that structure references must remain valid until the
-operation has completed.
-For this reason, use of auto (stack) variables
-for these objects is discouraged.
-.Pp
-The asynchronous I/O control buffer
-.Fa iocb
-should be zeroed before the
-.Fn aio_write
-system call to avoid passing bogus context information to the kernel.
-.Pp
-Modifications of the Asynchronous I/O Control Block structure or the
-buffer contents after the request has been enqueued, but before the
-request has completed, are not allowed.
-.Pp
-If the file offset in
-.Fa iocb->aio_offset
-is past the offset maximum for
-.Fa iocb->aio_fildes ,
-no I/O will occur.
-.Sh RETURN VALUES
-.Rv -std aio_write
-.Sh ERRORS
-The
-.Fn aio_write
-system call will fail if:
-.Bl -tag -width Er
-.It Bq Er EAGAIN
-The request was not queued because of system resource limitations.

-The
-.Fn aio_write
-system call is not supported.
-.El
-.Pp
-The following conditions may be synchronously detected when the
-.Fn aio_write
-system call is made, or asynchronously, at any time thereafter.
-If they
-are detected at call time,
-.Fn aio_write
-returns -1 and sets
-.Va errno
-appropriately; otherwise the
-.Fn aio_return
-system call must be called, and will return -1, and
-.Fn aio_error
-must be called to determine the actual value that would have been
-returned in
-.Va errno .
-.Bl -tag -width Er
-.It Bq Er EBADF
-The
-.Fa iocb->aio_fildes
-argument
-is invalid, or is not opened for writing.

-.Fa iocb->aio_reqprio
-is not a valid priority, or the number of bytes specified by

-is not valid.
-.El
-.Pp
-If the request is successfully enqueued, but subsequently canceled
-or an error occurs, the value returned by the
-.Fn aio_return
-system call is per the
-.Xr write 2

-.Fn brk "const void *addr"
-.Ft void *
-.Fn sbrk "intptr_t incr"
-.Sh DESCRIPTION
-.Bf -symbolic
-The
-.Fn brk
-and
-.Fn sbrk
-functions are legacy interfaces from before the
-advent of modern virtual memory management.
-.Ef
-.Pp
-The
-.Fn brk
-and
-.Fn sbrk
-functions are used to change the amount of memory allocated in a
-process's data segment.
-They do this by moving the location of the
-.Dq break .
-The break is the first address after the end of the process's
-uninitialized data segment (also known as the
-.Dq BSS ) .
-.Pp
-The
-.Fn brk
-function
-sets the break to
-.Fa addr .
-.Pp
-The
-.Fn sbrk
-function raises the break by
-.Fa incr
-bytes, thus allocating at least
-.Fa incr
-bytes of new memory in the data segment.
-If
-.Fa incr
-is negative,
-the break is lowered by
-.Fa incr
-bytes.
-.Sh NOTES
-While the actual process data segment size maintained by the kernel will only
-grow or shrink in page sizes, these functions allow setting the break
-to unaligned values (i.e., it may point to any address inside the last
-page of the data segment).
-.Pp
-The current value of the program break may be determined by calling
-.Fn sbrk 0 .
-See also
-.Xr end 3 .
-.Pp
-The
-.Xr getrlimit 2
-system call may be used to determine
-the maximum permissible size of the
-data segment.
-It will not be possible to set the break
-beyond
-.Dq Va etext No + Va rlim.rlim_max
-where the
-.Va rlim.rlim_max
-value is returned from a call to
-.Fn getrlimit RLIMIT_DATA &rlim .
-(See
-.Xr end 3
-for the definition of
-.Va etext ) .
-.Sh RETURN VALUES
-.Rv -std brk
-.Pp
-The
-.Fn sbrk
-function returns the prior break value if successful;
-otherwise the value
-.Po Vt "void *" Pc Ns \-1
-is returned and the global variable
-.Va errno
-is set to indicate the error.
-.Sh ERRORS
-The
-.Fn brk
-and
-.Fn sbrk
-functions
-will fail if:
-.Bl -tag -width Er
-.It Bq Er EINVAL
-The requested break value was beyond the beginning of the data segment.
-.It Bq Er ENOMEM
-The data segment size limit, as set by
-.Xr setrlimit 2 ,
-was exceeded.
-.It Bq Er ENOMEM
-Insufficient space existed in the swap area
-to support the expansion of the data segment.

-or similar functions will result in non-portable program behavior.

-.Fn chmod "const char *path" "mode_t mode"
-.Ft int
-.Fn fchmod "int fd" "mode_t mode"
-.Ft int
-.Fn lchmod "const char *path" "mode_t mode"
-.Ft int
-.Fn fchmodat "int fd" "const char *path" "mode_t mode" "int flag"
-.Sh DESCRIPTION
-The file permission bits of the file named specified by
-.Fa path
-or referenced by the file descriptor
-.Fa fd
-are changed to
-.Fa mode .
-The
-.Fn chmod
-system call verifies that the process owner (user) either owns
-the file specified by
-.Fa path
-(or
-.Fa fd ) ,
-or
-is the super-user.
-The
-.Fn chmod
-system call follows symbolic links to operate on the target of the link
-rather than the link itself.
-.Pp
-The
-.Fn lchmod
-system call is similar to
-.Fn chmod
-but does not follow symbolic links.
-.Pp
-The
-.Fn fchmodat
-is equivalent to either
-.Fn chmod
-or
-.Fn lchmod
-depending on the
-.Fa flag
-except in the case where
-.Fa path
-specifies a relative path.
-In this case the file to be changed is determined relative to the directory
-associated with the file descriptor
-.Fa fd
-instead of the current working directory.
-The values for the
-.Fa flag
-are constructed by a bitwise-inclusive OR of flags from the following list, defined
-in
-.In fcntl.h :
-.Bl -tag -width indent
-.It Dv AT_SYMLINK_NOFOLLOW
-If
-.Fa path
-names a symbolic link, then the mode of the symbolic link is changed.
-.El
-.Pp
-If
-.Fn fchmodat
-is passed the special value
-.Dv AT_FDCWD
-in the
-.Fa fd
-parameter, the current working directory is used.
-If also
-.Fa flag
-is zero, the behavior is identical to a call to
-.Fn chmod .
-.Pp
-A mode is created from
-.Em or'd
-permission bit masks
-defined in
-.In sys/stat.h :
-.Pp
-.Bd -literal -offset indent -compact
-#define S_IRWXU 0000700 /* RWX mask for owner */
-#define S_IRUSR 0000400 /* R for owner */
-#define S_IWUSR 0000200 /* W for owner */
-#define S_IXUSR 0000100 /* X for owner */
-
-#define S_IRWXG 0000070 /* RWX mask for group */
-#define S_IRGRP 0000040 /* R for group */
-#define S_IWGRP 0000020 /* W for group */
-#define S_IXGRP 0000010 /* X for group */
-
-#define S_IRWXO 0000007 /* RWX mask for other */
-#define S_IROTH 0000004 /* R for other */
-#define S_IWOTH 0000002 /* W for other */
-#define S_IXOTH 0000001 /* X for other */
-
-#define S_ISUID 0004000 /* set user id on execution */
-#define S_ISGID 0002000 /* set group id on execution */
-#ifndef __BSD_VISIBLE
-#define S_ISTXT 0001000 /* sticky bit */
-#endif
-.Ed
-.Pp
-The
-.Fx
-VM system totally ignores the sticky bit
-.Pq Dv ISTXT
-for executables.
-On UFS-based file systems (FFS, LFS) the sticky
-bit may only be set upon directories.
-.Pp
-If mode
-.Dv ISTXT
-(the `sticky bit') is set on a directory,
-an unprivileged user may not delete or rename
-files of other users in that directory.
-The sticky bit may be
-set by any user on a directory which the user owns or has appropriate
-permissions.
-For more details of the properties of the sticky bit, see
-.Xr sticky 8 .
-.Pp
-If mode ISUID (set UID) is set on a directory,
-and the MNT_SUIDDIR option was used in the mount of the file system,
-then the owner of any new files and sub-directories
-created within this directory are set
-to be the same as the owner of that directory.
-If this function is enabled, new directories will inherit
-the bit from their parents.
-Execute bits are removed from
-the file, and it will not be given to root.
-This behavior does not change the
-requirements for the user to be allowed to write the file, but only the eventual
-owner after it has been created.
-Group inheritance is not affected.
-.Pp
-This feature is designed for use on fileservers serving PC users via
-ftp, SAMBA, or netatalk.
-It provides security holes for shell users and as
-such should not be used on shell machines, especially on home directories.
-This option requires the SUIDDIR
-option in the kernel to work.
-Only UFS file systems support this option.
-For more details of the suiddir mount option, see
-.Xr mount 8 .
-.Pp
-Writing or changing the owner of a file
-turns off the set-user-id and set-group-id bits
-unless the user is the super-user.
-This makes the system somewhat more secure
-by protecting set-user-id (set-group-id) files
-from remaining set-user-id (set-group-id) if they are modified,
-at the expense of a degree of compatibility.

-.Sh LIBRARY

-.Sh SYNOPSIS
-.In unistd.h
-.Ft int
-.Fn chroot "const char *dirname"
-.Sh DESCRIPTION
-The
-.Fa dirname
-argument
-is the address of the pathname of a directory, terminated by an ASCII NUL.
-The
-.Fn chroot
-system call causes
-.Fa dirname
-to become the root directory,
-that is, the starting point for path searches of pathnames
-beginning with
-.Ql / .
-.Pp
-In order for a directory to become the root directory
-a process must have execute (search) access for that directory.
-.Pp
-It should be noted that
-.Fn chroot
-has no effect on the process's current directory.
-.Pp
-This call is restricted to the super-user.
-.Pp
-Depending on the setting of the
-.Ql kern.chroot_allow_open_directories
-sysctl variable, open filedescriptors which reference directories
-will make the
-.Fn chroot
-fail as follows:
-.Pp
-If
-.Ql kern.chroot_allow_open_directories
-is set to zero,
-.Fn chroot
-will always fail with
-.Er EPERM
-if there are any directories open.
-.Pp
-If
-.Ql kern.chroot_allow_open_directories
-is set to one (the default),
-.Fn chroot
-will fail with
-.Er EPERM
-if there are any directories open and the
-process is already subject to the
-.Fn chroot
-system call.
-.Pp
-Any other value for
-.Ql kern.chroot_allow_open_directories
-will bypass the check for open directories
-.Pp
-Upon successful completion, a value of 0 is returned.
-Otherwise,
-a value of -1 is returned and
-.Va errno
-is set to indicate an error.
-.Sh ERRORS
-The
-.Fn chroot
-system call
-will fail and the root directory will be unchanged if:
-.Bl -tag -width Er
-.It Bq Er ENOTDIR
-A component of the path name is not a directory.
-.It Bq Er EPERM
-The effective user ID is not the super-user, or one or more
-filedescriptors are open directories.
-.It Bq Er ENAMETOOLONG
-A component of a pathname exceeded 255 characters,
-or an entire path name exceeded 1023 characters.
-.It Bq Er ENOENT
-The named directory does not exist.
-.It Bq Er EACCES
-Search permission is denied for any component of the path name.
-.It Bq Er ELOOP
-Too many symbolic links were encountered in translating the pathname.
-.It Bq Er EFAULT
-The
-.Fa dirname
-argument
-points outside the process's allocated address space.
-.It Bq Er EIO
-An I/O error occurred while reading from or writing to the file system.
-.El
-.Sh SEE ALSO
-.Xr chdir 2 ,

-.Sh BUGS
-If the process is able to change its working directory to the target
-directory, but another access control check fails (such as a check for
-open directories, or a MAC check), it is possible that this system
-call may return an error, with the working directory of the process
-left changed.

-.Ft int
-.Fn clock_getres "clockid_t clock_id" "struct timespec *tp"
-.Sh DESCRIPTION
-The
-.Fn clock_gettime
-and
-.Fn clock_settime
-system calls allow the calling process to retrieve or set the value
-used by a clock which is specified by
-.Fa clock_id .
-.Pp
-The
-.Fa clock_id
-argument
-can be one of the following values:
-.Dv CLOCK_REALTIME ,
-.Dv CLOCK_REALTIME_PRECISE ,
-.Dv CLOCK_REALTIME_FAST
-for time that increments as
-a wall clock should;
-.Dv CLOCK_MONOTONIC ,
-.Dv CLOCK_MONOTONIC_PRECISE ,
-.Dv CLOCK_MONOTONIC_FAST
-which increments in SI seconds;
-.Dv CLOCK_UPTIME ,
-.Dv CLOCK_UPTIME_PRECISE ,
-.Dv CLOCK_UPTIME_FAST
-which starts at zero when the kernel boots and increments
-monotonically in SI seconds while the machine is running;
-.Dv CLOCK_VIRTUAL
-for time that increments only when
-the CPU is running in user mode on behalf of the calling process;
-.Dv CLOCK_PROF
-for time that increments when the CPU is running in user or
-kernel mode; or
-.Dv CLOCK_SECOND
-which returns the current second without performing a full time counter
-query, using in-kernel cached value of current second.
-.Pp
-The clock IDs
-.Fa CLOCK_REALTIME_FAST ,
-.Fa CLOCK_MONOTONIC_FAST ,
-.Fa CLOCK_UPTIME_FAST
-are analogs of corresponding IDs without _FAST suffix but do not perform
-a full time counter query, so their accuracy is one timer tick.
-Similarly,
-.Fa CLOCK_REALTIME_PRECISE ,
-.Fa CLOCK_MONOTONIC_PRECISE ,
-.Fa CLOCK_UPTIME_PRECISE
-are used to get the most exact value as possible, at the expense of
-execution time.
-.Pp
-The structure pointed to by
-.Fa tp
-is defined in
-.In sys/timespec.h
-as:
-.Bd -literal
-struct timespec {
- time_t tv_sec; /* seconds */
- long tv_nsec; /* and nanoseconds */
-};
-.Ed
-.Pp
-Only the super-user may set the time of day, using only
-.Fa CLOCK_REALTIME .
-If the system securelevel is greater than 1 (see
-.Xr init 8 ) ,
-the time may only be advanced.
-This limitation is imposed to prevent a malicious super-user
-from setting arbitrary time stamps on files.
-The system time can still be adjusted backwards using the
-.Xr adjtime 2
-system call even when the system is secure.
-.Pp
-The resolution (granularity) of a clock is returned by the
-.Fn clock_getres
-system call.
-This value is placed in a (non-NULL)
-.Fa *tp .
-.Sh RETURN VALUES
-.Rv -std
-.Sh ERRORS
-The following error codes may be set in
-.Va errno :
-.Bl -tag -width Er
-.It Bq Er EINVAL
-The
-.Fa clock_id
-argument
-was not a valid value.
-.It Bq Er EFAULT
-The
-.Fa *tp
-argument address referenced invalid memory.
-.It Bq Er EPERM
-A user other than the super-user attempted to set the time.
-.El
-.Sh SEE ALSO

-.Sh STANDARDS
-The

-.Nd delete a descriptor
-.Sh LIBRARY
-.Lb libc
-.Sh SYNOPSIS
-.In unistd.h
-.Ft int
-.Fn close "int d"
-.Sh DESCRIPTION
-The
-.Fn close
-system call deletes a descriptor from the per-process object
-reference table.
-If this is the last reference to the underlying object, the
-object will be deactivated.
-For example, on the last close of a file
-the current
-.Em seek
-pointer associated with the file is lost;
-on the last close of a
-.Xr socket 2
-associated naming information and queued data are discarded;
-on the last close of a file holding an advisory lock
-the lock is released (see further
-.Xr flock 2 ) .
-However, the semantics of System V and
-.St -p1003.1-88
-dictate that all
-.Xr fcntl 2
-advisory record locks associated with a file for a given process
-are removed when
-.Em any
-file descriptor for that file is closed by that process.
-.Pp
-When a process exits,
-all associated file descriptors are freed, but since there is
-a limit on active descriptors per processes, the
-.Fn close
-system call
-is useful when a large quantity of file descriptors are being handled.
-.Pp
-When a process forks (see
-.Xr fork 2 ) ,
-all descriptors for the new child process reference the same
-objects as they did in the parent before the fork.
-If a new process is then to be run using
-.Xr execve 2 ,
-the process would normally inherit these descriptors.
-Most
-of the descriptors can be rearranged with
-.Xr dup2 2
-or deleted with
-.Fn close
-before the
-.Xr execve 2
-is attempted, but if some of these descriptors will still
-be needed if the execve fails, it is necessary to arrange for them
-to be closed if the execve succeeds.
-For this reason, the call
-.Dq Li fcntl(d, F_SETFD, FD_CLOEXEC)
-is provided,
-which arranges that a descriptor will be closed after a successful
-execve; the call
-.Dq Li fcntl(d, F_SETFD, 0)
-restores the default,
-which is to not close the descriptor.
-.Sh RETURN VALUES
-.Rv -std close

-The

-.Sh DESCRIPTION
-The
-.Nm
-family of system calls allow applications to control sets of processors and
-assign processes and threads to these sets.
-Processor sets contain lists of CPUs that members may run on and exist only
-as long as some process is a member of the set.
-All processes in the system have an assigned set.
-The default set for all processes in the system is the set numbered 1.
-Threads belong to the same set as the process which contains them,
-however, they may further restrict their set with the anonymous
-per-thread mask.
-.Pp
-Sets are referenced by a number of type
-.Ft cpuset_id_t .
-Each thread has a root set, an assigned set, and an anonymous mask.
-Only the root and assigned sets are numbered.
-The root set is the set of all CPUs available in the system or in the
-system partition the thread is running in.
-The assigned set is a subset of the root set and is administratively
-assignable on a per-process basis.
-Many processes and threads may be members of a numbered set.
-.Pp
-The anonymous set is a further thread-specific refinement on the assigned
-set.
-It is intended that administrators will manipulate numbered sets using
-.Xr cpuset 1
-while application developers will manipulate anonymous sets using
-.Xr cpuset_setaffinity 2 .
-.Pp
-To select the correct set a value of type
-.Ft cpulevel_t
-is used.
-The following values for
-.Fa level
-are supported:
-.Bl -column CPU_LEVEL_CPUSET -offset indent
-.It Dv CPU_LEVEL_ROOT Ta "Root set"
-.It Dv CPU_LEVEL_CPUSET Ta "Assigned set"
-.It Dv CPU_LEVEL_WHICH Ta "Set specified by which argument"

-not permit changing the id of an existing set.
-Upon successful completion all of the threads in the target process will
-be running on CPUs permitted by the set.
-.Pp
-.Fn cpuset_getid
-retrieves a set id from the object indicated by

-The retrieved id may be that of either the root or assigned set
-depending on the value of
-.Fa level .
-.Fa level
-should be
-.Dv CPU_LEVEL_CPUSET
-or
-.Dv CPU_LEVEL_ROOT
-to get the set id from
-the process or thread specified by the
-.Fa id
-argument.
-Specifying
-.Dv CPU_LEVEL_WHICH
-with a process or thread is unsupported since
-this references the unnumbered anonymous mask.
-.Pp
-The actual contents of the sets may be retrieved or manipulated using

-.Sh DESCRIPTION
-.Fn cpuset_getaffinity
-and
-.Fn cpuset_setaffinity
-allow the manipulation of sets of CPUs available to processes, threads,
-interrupts, jails and other resources.
-These functions may manipulate sets of CPUs that contain many processes
-or per-object anonymous masks that effect only a single object.
-.Pp
-The valid values for the
-.Fa level
-and
-.Fa which
-arguments are documented in
-.Xr cpuset 2 .
-These arguments specify which object and which set of the object we are
-referring to.
-Not all possible combinations are valid.
-For example, only processes may belong to a numbered set accessed by a
-.Fa level
-argument of
-.Dv CPU_LEVEL_CPUSET .
-All resources, however, have a mask which may be manipulated with
-.Dv CPU_LEVEL_WHICH .
-.Pp
-Masks of type
-.Ft cpuset_t
-are composed using the
-.Xr CPU_SET 2
-macros.
-The kernel tolerates large sets as long as all CPUs specified
-in the set exist.
-Sets smaller than the kernel uses generate an error on calls to
-.Fn cpuset_getaffinity
-even if the result set would fit within the user supplied set.
-Calls to
-.Fn cpuset_setaffinity
-tolerate small sets with no restrictions.
-.Pp
-The supplied mask should have a size of
-.Fa setsize
-bytes.
-This size is usually provided by calling
-.Li sizeof(mask)
-which is ultimately determined by the value of
-.Dv CPU_SETSIZE
-as defined in
-.In sys/cpuset.h .
-.Pp
-.Fn cpuset_getaffinity
-retrieves the
-mask from the object specified by
-.Fa level ,
-.Fa which
-and
-.Fa id
-and stores it in the space provided by
-.Fa mask .
-.Pp
-.Fn cpuset_setaffinity

-.Sh DESCRIPTION
-The
-.Fn dup
-system call
-duplicates an existing object descriptor and returns its value to
-the calling process
-.Fa ( newd
-=
-.Fn dup oldd ) .
-The argument
-.Fa oldd
-is a small non-negative integer index in
-the per-process descriptor table.
-The value must be less
-than the size of the table, which is returned by
-.Xr getdtablesize 2 .
-The new descriptor returned by the call
-is the lowest numbered descriptor
-currently not in use by the process.
-.Pp
-The object referenced by the descriptor does not distinguish
-between

-calls all move a single pointer into the file,
-and append mode, non-blocking I/O and asynchronous I/O options
-are shared between the references.
-If a separate pointer into the file is desired, a different
-object reference to the file must be obtained by issuing an
-additional
-.Xr open 2
-system call.
-The close-on-exec flag on the new file descriptor is unset.
-.Pp
-In
-.Fn dup2 ,
-the value of the new descriptor
-.Fa newd
-is specified.
-If this descriptor is already in use and

-\*(Ne
-.Fa newd ,
-the descriptor is first deallocated as if the

-If

-is not a valid descriptor, then
-.Fa newd
-is not closed.
-If
-.Fa oldd

-.Dt EXECVE 2
-.Os
-.Sh NAME
-.Nm execve ,
-.Nm fexecve
-.Nd execute a file
-.Sh LIBRARY
-.Lb libc
-.Sh SYNOPSIS
-.In unistd.h
-.Ft int
-.Fn execve "const char *path" "char *const argv[]" "char *const envp[]"
-.Ft int
-.Fn fexecve "int fd" "char *const argv[]" "char *const envp[]"
-.Sh DESCRIPTION
-The
-.Fn execve
-system call
-transforms the calling process into a new process.
-The new process is constructed from an ordinary file,
-whose name is pointed to by
-.Fa path ,
-called the
-.Em new process file .
-The
-.Fn fexecve
-system call is equivalent to
-.Fn execve
-except that the file to be executed is determined by the file
-descriptor
-.Fa fd
-instead of a
-.Fa path .
-This file is either an executable object file,
-or a file of data for an interpreter.
-An executable object file consists of an identifying header,
-followed by pages of data representing the initial program (text)
-and initialized data pages.
-Additional pages may be specified
-by the header to be initialized with zero data; see
-.Xr elf 5
-and
-.Xr a.out 5 .
-.Pp
-An interpreter file begins with a line of the form:
-.Pp
-.Bd -ragged -offset indent -compact
-.Sy \&#!
-.Em interpreter
-.Bq Em arg
-.Ed
-.Pp
-When an interpreter file is
-.Sy execve Ap d ,
-the system actually
-.Sy execve Ap s
-the specified
-.Em interpreter .
-If the optional
-.Em arg
-is specified, it becomes the first argument to the
-.Em interpreter ,
-and the name of the originally
-.Sy execve Ap d
-file becomes the second argument;
-otherwise, the name of the originally
-.Sy execve Ap d
-file becomes the first argument.
-The original arguments are shifted over to
-become the subsequent arguments.
-The zeroth argument is set to the specified
-.Em interpreter .
-.Pp
-The argument
-.Fa argv
-is a pointer to a null-terminated array of
-character pointers to null-terminated character strings.
-These strings construct the argument list to be made available to the new
-process.
-At least one argument must be present in
-the array; by custom, the first element should be
-the name of the executed program (for example, the last component of
-.Fa path ) .
-.Pp
-The argument
-.Fa envp
-is also a pointer to a null-terminated array of
-character pointers to null-terminated strings.
-A pointer to this array is normally stored in the global variable
-.Va environ .
-These strings pass information to the
-new process that is not directly an argument to the command (see
-.Xr environ 7 ) .
-.Pp
-File descriptors open in the calling process image remain open in
-the new process image, except for those for which the close-on-exec
-flag is set (see
-.Xr close 2
-and
-.Xr fcntl 2 ) .
-Descriptors that remain open are unaffected by
-.Fn execve .
-If any of the standard descriptors (0, 1, and/or 2) are closed at the
-time
-.Fn execve
-is called, and the process will gain privilege as a result of set-id
-semantics, those descriptors will be re-opened automatically.
-No programs, whether privileged or not, should assume that these descriptors
-will remain closed across a call to
-.Fn execve .
-.Pp
-Signals set to be ignored in the calling process are set to be ignored in
-the
-new process.
-Signals which are set to be caught in the calling process image
-are set to default action in the new process image.
-Blocked signals remain blocked regardless of changes to the signal action.
-The signal stack is reset to be undefined (see
-.Xr sigaction 2
-for more information).
-.Pp
-If the set-user-ID mode bit of the new process image file is set
-(see
-.Xr chmod 2 ) ,
-the effective user ID of the new process image is set to the owner ID
-of the new process image file.
-If the set-group-ID mode bit of the new process image file is set,
-the effective group ID of the new process image is set to the group ID
-of the new process image file.
-(The effective group ID is the first element of the group list.)
-The real user ID, real group ID and
-other group IDs of the new process image remain the same as the calling
-process image.
-After any set-user-ID and set-group-ID processing,
-the effective user ID is recorded as the saved set-user-ID,
-and the effective group ID is recorded as the saved set-group-ID.
-These values may be used in changing the effective IDs later (see
-.Xr setuid 2 ) .
-.Pp
-The set-ID bits are not honored if the respective file system has the
-.Cm nosuid
-option enabled or if the new process file is an interpreter file.
-Syscall
-tracing is disabled if effective IDs are changed.
-.Pp
-The new process also inherits the following attributes from
-the calling process:
-.Pp
-.Bl -column parent_process_ID -offset indent -compact
-.It process ID Ta see Xr getpid 2
-.It parent process ID Ta see Xr getppid 2
-.It process group ID Ta see Xr getpgrp 2
-.It access groups Ta see Xr getgroups 2
-.It working directory Ta see Xr chdir 2
-.It root directory Ta see Xr chroot 2
-.It control terminal Ta see Xr termios 4
-.It resource usages Ta see Xr getrusage 2
-.It interval timers Ta see Xr getitimer 2
-.It resource limits Ta see Xr getrlimit 2
-.It file mode mask Ta see Xr umask 2
-.It signal mask Ta see Xr sigaction 2 ,
-.Xr sigprocmask 2
-.El
-.Pp
-When a program is executed as a result of an
-.Fn execve
-system call, it is entered as follows:
-.Bd -literal -offset indent
-main(argc, argv, envp)
-int argc;
-char **argv, **envp;
-.Ed
-.Pp
-where
-.Fa argc
-is the number of elements in
-.Fa argv
-(the ``arg count'')
-and
-.Fa argv
-points to the array of character pointers
-to the arguments themselves.
-.Pp
-The
-.Fn fexecve
-ignores the file offset of
-.Fa fd .
-Since execute permission is checked by
-.Fn fexecve ,
-the file descriptor
-.Fa fd
-need not have been opened with the
-.Dv O_EXEC
-flag.
-However, if the file to be executed denies read permission for the process
-preparing to do the exec, the only way to provide the
-.Fa fd
-to
-.Fn fexecve
-is to use the
-.Dv O_EXEC
-flag when opening
-.Fa fd .
-Note that the file to be executed can not be open for writing.
-.Sh RETURN VALUES
-As the
-.Fn execve
-system call overlays the current process image
-with a new process image the successful call
-has no process to return to.
-If
-.Fn execve
-does return to the calling process an error has occurred; the
-return value will be -1 and the global variable
-.Va errno
-is set to indicate the error.
-.Sh ERRORS
-The
-.Fn execve
-system call
-will fail and return to the calling process if:
-.Bl -tag -width Er
-.It Bq Er ENOTDIR
-A component of the path prefix is not a directory.
-.It Bq Er ENAMETOOLONG
-A component of a pathname exceeded 255 characters,
-or an entire path name exceeded 1023 characters.
-.It Bq Er ENOEXEC
-When invoking an interpreted script, the length of the first line,

-.It Bq Er ENOENT
-The new process file does not exist.
-.It Bq Er ELOOP
-Too many symbolic links were encountered in translating the pathname.
-.It Bq Er EACCES

-.It Bq Er EACCES
-The new process file is not an ordinary file.
-.It Bq Er EACCES
-The new process file mode denies execute permission.
-.It Bq Er ENOEXEC
-The new process file has the appropriate access

-.It Bq Er ETXTBSY
-The new process file is a pure procedure (shared text)

-.It Bq Er ENOMEM
-The new process requires more virtual memory than
-is allowed by the imposed maximum
-.Pq Xr getrlimit 2 .
-.It Bq Er E2BIG
-The number of bytes in the new process' argument list

-.Sh STANDARDS
-The
-.Fn execve
-system call conforms to
-.St -p1003.1-2001 ,
-with the exception of reopening descriptors 0, 1, and/or 2 in certain
-circumstances.
-A future update of the Standard is expected to require this behavior,
-and it may become the default for non-privileged processes as well.
-.\" NB: update this caveat when TC1 is blessed.
-The support for executing interpreted programs is an extension.
-The
-.Fn fexecve
-system call conforms to The Open Group Extended API Set 2 specification.
-.Sh HISTORY
-The
-.Fn execve
-system call appeared in
-.Bx 4.2 .
-The
-.Fn fexecve
-system call appeared in
-.Fx 8.0 .
-.Sh CAVEATS
-If a program is
-.Em setuid
-to a non-super-user, but is executed when
-the real
-.Em uid
-is ``root'', then the program has some of the powers
-of a super-user as well.
-.Pp
-When executing an interpreted program through
-.Fn fexecve ,
-kernel supplies
-.Pa /dev/fd/n
-as a second argument to the interpreter,
-where
-.Ar n
-is the file descriptor passed in the
-.Fa fd
-argument to
-.Fn fexecve .
-For this construction to work correctly, the

-.Sh DESCRIPTION
-Named extended attributes are meta-data associated with vnodes
-representing files and directories.
-They exist as
-.Qq Li name=value
-pairs within a set of namespaces.
-.Pp
-The
-.Fn extattr_get_file
-system call retrieves the value of the specified extended attribute into
-a buffer pointed to by
-.Fa data
-of size
-.Fa nbytes .
-The
-.Fn extattr_set_file
-system call sets the value of the specified extended attribute to the data
-described by
-.Fa data .
-The
-.Fn extattr_delete_file
-system call deletes the extended attribute specified.
-The
-.Fn extattr_list_file
-returns a list of attributes present in the requested namespace.
-Each list entry consists of a single byte containing the length
-of the attribute name, followed by the attribute name.
-The attribute name is not terminated by ASCII 0 (nul).
-The
-.Fn extattr_get_file ,
-and
-.Fn extattr_list_file
-calls consume the
-.Fa data
-and
-.Fa nbytes
-arguments in the style of
-.Xr read 2 ;
-.Fn extattr_set_file
-consumes these arguments in the style of
-.Xr write 2 .
-.Pp
-If
-.Fa data
-is
-.Dv NULL
-in a call to
-.Fn extattr_get_file
-and
-.Fn extattr_list_file
-then the size of defined extended attribute data will be returned, rather
-than the quantity read, permitting applications to test the size of the
-data without performing a read.
-The
-.Fn extattr_delete_link ,
-.Fn extattr_get_link ,
-and
-.Fn extattr_set_link
-system calls behave in the same way as their _file counterparts, except that
-they do not follow symlinks.
-.Pp
-The
-.Fn extattr_get_fd ,
-.Fn extattr_set_fd ,
-.Fn extattr_delete_fd ,
-and
-.Fn extattr_list_fd ,
-calls are identical to their
-.Qq Li _file
-counterparts except for the first argument.
-The
-.Qq Li _fd
-functions take a file descriptor, while the
-.Qq Li _file
-functions take a path.
-Both arguments describe a file associated with the extended attribute
-that should be manipulated.
-.Pp
-The following arguments are common to all the system calls described here:
-.Bl -tag -width attrnamespace
-.It Fa attrnamespace
-the namespace in which the extended attribute resides; see
-.Xr extattr 9
-.It Fa attrname
-the name of the extended attribute
-.El
-.Pp
-Named extended attribute semantics vary by file system implementing the call.
-Not all operations may be supported for a particular attribute.
-Additionally, the format of the data in
-.Fa data
-is attribute-specific.
-.Pp
-For more information on named extended attributes, please see
-.Xr extattr 9 .
-.Sh CAVEAT
-This interface is under active development, and as such is subject to
-change as applications are adapted to use it.
-Developers are discouraged from relying on its stability.
-.Sh RETURN VALUES
-If successful, the
-.Fn extattr_get_file ,
-.Fn extattr_set_file ,
-and
-.Fn extattr_list_file
-calls return the number of bytes
-that were read or written from the
-.Fa data ,
-respectively, or if
-.Fa data
-was
-.Dv NULL ,
-then
-.Fn extattr_get_file
-and
-.Fn extattr_list_file
-return the number of bytes available to read.
-If any of the calls are unsuccessful, the value \-1 is returned
-and the global variable
-.Va errno
-is set to indicate the error.
-.Pp
-.Rv -std extattr_delete_file
-.Sh ERRORS
-The following errors may be returned by the system calls themselves.
-Additionally, the file system implementing the call may return any
-other errors it desires.
-.Bl -tag -width Er
-.It Bq Er EFAULT
-The
-.Fa attrnamespace
-and
-.Fa attrname
-arguments,
-or the memory range defined by
-.Fa data
-and
-.Fa nbytes
-point outside the process's allocated address space.
-.It Bq Er ENAMETOOLONG
-The attribute name was longer than
-.Dv EXTATTR_MAXNAMELEN .
-.El
-.Pp
-The
-.Fn extattr_get_fd ,
-.Fn extattr_set_fd ,
-.Fn extattr_delete_fd ,
-and
-.Fn extattr_list_fd
-system calls may also fail if:
-.Bl -tag -width Er
-.It Bq Er EBADF
-The file descriptor referenced by
-.Fa fd
-was invalid.
-.El
-.Pp
-Additionally, the
-.Fn extattr_get_file ,
-.Fn extattr_set_file ,
-and
-.Fn extattr_delete_file
-calls may also fail due to the following errors:
-.Bl -tag -width Er
-.It Bq Er ENOATTR
-The requested attribute was not defined for this file.
-.It Bq Er ENOTDIR
-A component of the path prefix is not a directory.
-.It Bq Er ENAMETOOLONG
-A component of a pathname exceeded 255 characters,
-or an entire path name exceeded 1023 characters.
-.It Bq Er ENOENT
-A component of the path name that must exist does not exist.
-.It Bq Er EACCES
-Search permission is denied for a component of the path prefix.

-.Sh HISTORY
-Extended attribute support was developed as part of the
-.Tn TrustedBSD
-Project, and introduced in
-.Fx 5.0 .
-It was developed to support security extensions requiring additional labels
-to be associated with each file or directory.
-.Sh BUGS
-In earlier versions of this API, passing an empty string for the
-attribute name to
-.Fn extattr_get_fd ,
-.Fn extattr_get_file ,
-or
-.Fn extattr_get_link
-would return the list of attributes defined for the target object.
-This interface has been deprecated in preference to using the explicit
-list API, and should not be used.

-.Sh NAME
-.Nm fcntl
-.Nd file control
-.Sh LIBRARY
-.Lb libc
-.Sh SYNOPSIS
-.In fcntl.h
-.Ft int
-.Fn fcntl "int fd" "int cmd" "..."
-.Sh DESCRIPTION
-The
-.Fn fcntl
-system call provides for control over descriptors.
-The argument
-.Fa fd
-is a descriptor to be operated on by
-.Fa cmd
-as described below.
-Depending on the value of
-.Fa cmd ,
-.Fn fcntl
-can take an additional third argument
-.Fa "int arg" .
-.Bl -tag -width F_GETOWNX
-.It Dv F_DUPFD
-Return a new descriptor as follows:
-.Pp
-.Bl -bullet -compact -offset 4n
-.It
-Lowest numbered available descriptor greater than or equal to
-.Fa arg .
-.It
-Same object references as the original descriptor.
-.It
-New descriptor shares the same file offset if the object
-was a file.
-.It
-Same access mode (read, write or read/write).
-.It
-Same file status flags (i.e., both file descriptors
-share the same file status flags).
-.It
-The close-on-exec flag associated with the new file descriptor
-is set to remain open across
-.Xr execve 2
-system calls.
-.El
-.It Dv F_DUP2FD
-It is functionally equivalent to
-.Bd -literal -offset indent
-dup2(fd, arg)
-.Ed
-.Pp
-The
-.Dv F_DUP2FD
-constant is not portable, so it should not be used if portability is needed.
-Use
-.Fn dup2
-instead.
-.It Dv F_GETFD
-Get the close-on-exec flag associated with the file descriptor
-.Fa fd
-as
-.Dv FD_CLOEXEC .
-If the returned value ANDed with
-.Dv FD_CLOEXEC
-is 0,
-the file will remain open across
-.Fn exec ,
-otherwise the file will be closed upon execution of
-.Fn exec
-.Fa ( arg
-is ignored).
-.It Dv F_SETFD
-Set the close-on-exec flag associated with
-.Fa fd
-to
-.Fa arg ,
-where
-.Fa arg
-is either 0 or
-.Dv FD_CLOEXEC ,
-as described above.
-.It Dv F_GETFL
-Get descriptor status flags, as described below
-.Fa ( arg
-is ignored).
-.It Dv F_SETFL
-Set descriptor status flags to
-.Fa arg .
-.It Dv F_GETOWN
-Get the process ID or process group
-currently receiving
-.Dv SIGIO
-and
-.Dv SIGURG
-signals; process groups are returned
-as negative values
-.Fa ( arg
-is ignored).
-.It Dv F_SETOWN
-Set the process or process group
-to receive
-.Dv SIGIO
-and
-.Dv SIGURG
-signals;
-process groups are specified by supplying
-.Fa arg
-as negative, otherwise
-.Fa arg
-is interpreted as a process ID.
-.El
-.Pp
-The flags for the
-.Dv F_GETFL
-and
-.Dv F_SETFL
-flags are as follows:
-.Bl -tag -width O_NONBLOCKX
-.It Dv O_NONBLOCK
-Non-blocking I/O; if no data is available to a
-.Xr read 2
-system call, or if a
-.Xr write 2
-operation would block,
-the read or write call returns -1 with the error
-.Er EAGAIN .
-.It Dv O_APPEND
-Force each write to append at the end of file;
-corresponds to the
-.Dv O_APPEND
-flag of
-.Xr open 2 .
-.It Dv O_DIRECT
-Minimize or eliminate the cache effects of reading and writing.
-The system
-will attempt to avoid caching the data you read or write.
-If it cannot
-avoid caching the data, it will minimize the impact the data has on the cache.
-Use of this flag can drastically reduce performance if not used with care.
-.It Dv O_ASYNC
-Enable the
-.Dv SIGIO
-signal to be sent to the process group
-when I/O is possible, e.g.,
-upon availability of data to be read.
-.El
-.Pp
-Several commands are available for doing advisory file locking;
-they all operate on the following structure:
-.Bd -literal
-struct flock {
- off_t l_start; /* starting offset */
- off_t l_len; /* len = 0 means until end of file */
- pid_t l_pid; /* lock owner */
- short l_type; /* lock type: read/write, etc. */
- short l_whence; /* type of l_start */
- int l_sysid; /* remote system id or zero for local */
-};
-.Ed
-The commands available for advisory record locking are as follows:
-.Bl -tag -width F_SETLKWX
-.It Dv F_GETLK
-Get the first lock that blocks the lock description pointed to by the
-third argument,
-.Fa arg ,
-taken as a pointer to a
-.Fa "struct flock"
-(see above).
-The information retrieved overwrites the information passed to
-.Fn fcntl
-in the
-.Fa flock
-structure.
-If no lock is found that would prevent this lock from being created,
-the structure is left unchanged by this system call except for the
-lock type which is set to
-.Dv F_UNLCK .
-.It Dv F_SETLK
-Set or clear a file segment lock according to the lock description
-pointed to by the third argument,
-.Fa arg ,
-taken as a pointer to a
-.Fa "struct flock"
-(see above).
-.Dv F_SETLK
-is used to establish shared (or read) locks
-.Pq Dv F_RDLCK
-or exclusive (or write) locks,
-.Pq Dv F_WRLCK ,
-as well as remove either type of lock
-.Pq Dv F_UNLCK .
-If a shared or exclusive lock cannot be set,
-.Fn fcntl
-returns immediately with
-.Er EAGAIN .
-.It Dv F_SETLKW
-This command is the same as
-.Dv F_SETLK
-except that if a shared or exclusive lock is blocked by other locks,
-the process waits until the request can be satisfied.
-If a signal that is to be caught is received while
-.Fn fcntl
-is waiting for a region, the
-.Fn fcntl
-will be interrupted if the signal handler has not specified the
-.Dv SA_RESTART
-(see
-.Xr sigaction 2 ) .
-.It Dv F_READAHEAD
-Set or clear the read ahead amount for sequential access to the third
-argument,
-.Fa arg ,
-which is rounded up to the nearest block size.
-A zero value in
-.Fa arg
-turns off read ahead.
-.It Dv F_RDAHEAD
-Equivalent to Darwin counterpart which sets read ahead amount of 128KB
-when the third argument,
-.Fa arg
-is non-zero.
-A zero value in
-.Fa arg
-turns off read ahead.
-.El
-.Pp
-When a shared lock has been set on a segment of a file,
-other processes can set shared locks on that segment
-or a portion of it.
-A shared lock prevents any other process from setting an exclusive
-lock on any portion of the protected area.
-A request for a shared lock fails if the file descriptor was not
-opened with read access.
-.Pp
-An exclusive lock prevents any other process from setting a shared lock or
-an exclusive lock on any portion of the protected area.
-A request for an exclusive lock fails if the file was not
-opened with write access.
-.Pp
-The value of
-.Fa l_whence
-is
-.Dv SEEK_SET ,
-.Dv SEEK_CUR ,
-or
-.Dv SEEK_END
-to indicate that the relative offset,
-.Fa l_start
-bytes, will be measured from the start of the file,
-current position, or end of the file, respectively.
-The value of
-.Fa l_len
-is the number of consecutive bytes to be locked.
-If
-.Fa l_len
-is negative,
-.Fa l_start
-means end edge of the region.
-The
-.Fa l_pid
-and
-.Fa l_sysid
-fields are only used with
-.Dv F_GETLK
-to return the process ID of the process holding a blocking lock and
-the system ID of the system that owns that process.
-Locks created by the local system will have a system ID of zero.
-After a successful
-.Dv F_GETLK
-request, the value of
-.Fa l_whence
-is
-.Dv SEEK_SET .
-.Pp
-Locks may start and extend beyond the current end of a file,
-but may not start or extend before the beginning of the file.
-A lock is set to extend to the largest possible value of the
-file offset for that file if
-.Fa l_len
-is set to zero.
-If
-.Fa l_whence
-and
-.Fa l_start
-point to the beginning of the file, and
-.Fa l_len
-is zero, the entire file is locked.
-If an application wishes only to do entire file locking, the
-.Xr flock 2
-system call is much more efficient.
-.Pp
-There is at most one type of lock set for each byte in the file.
-Before a successful return from an
-.Dv F_SETLK
-or an
-.Dv F_SETLKW
-request when the calling process has previously existing locks
-on bytes in the region specified by the request,
-the previous lock type for each byte in the specified
-region is replaced by the new lock type.
-As specified above under the descriptions
-of shared locks and exclusive locks, an
-.Dv F_SETLK
-or an
-.Dv F_SETLKW
-request fails or blocks respectively when another process has existing
-locks on bytes in the specified region and the type of any of those
-locks conflicts with the type specified in the request.
-.Pp
-This interface follows the completely stupid semantics of System V and
-.St -p1003.1-88
-that require that all locks associated with a file for a given process are
-removed when
-.Em any
-file descriptor for that file is closed by that process.
-This semantic means that applications must be aware of any files that
-a subroutine library may access.
-For example if an application for updating the password file locks the
-password file database while making the update, and then calls
-.Xr getpwnam 3
-to retrieve a record,
-the lock will be lost because
-.Xr getpwnam 3
-opens, reads, and closes the password database.
-The database close will release all locks that the process has
-associated with the database, even if the library routine never
-requested a lock on the database.
-Another minor semantic problem with this interface is that
-locks are not inherited by a child process created using the
-.Xr fork 2
-system call.
-The
-.Xr flock 2
-interface has much more rational last close semantics and
-allows locks to be inherited by child processes.
-The
-.Xr flock 2
-system call is recommended for applications that want to ensure the integrity
-of their locks when using library routines or wish to pass locks
-to their children.
-.Pp
-The
-.Fn fcntl ,
-.Xr flock 2 ,
-and
-.Xr lockf 3
-locks are compatible.
-Processes using different locking interfaces can cooperate
-over the same file safely.
-However, only one of such interfaces should be used within
-the same process.
-If a file is locked by a process through
-.Xr flock 2 ,
-any record within the file will be seen as locked
-from the viewpoint of another process using
-.Fn fcntl
-or
-.Xr lockf 3 ,
-and vice versa.
-Note that
-.Fn fcntl F_GETLK
-returns \-1 in
-.Fa l_pid
-if the process holding a blocking lock previously locked the
-file descriptor by
-.Xr flock 2 .
-.Pp
-All locks associated with a file for a given process are
-removed when the process terminates.
-.Pp
-All locks obtained before a call to
-.Xr execve 2
-remain in effect until the new program releases them.
-If the new program does not know about the locks, they will not be
-released until the program exits.
-.Pp
-A potential for deadlock occurs if a process controlling a locked region
-is put to sleep by attempting to lock the locked region of another process.
-This implementation detects that sleeping until a locked region is unlocked
-would cause a deadlock and fails with an
-.Er EDEADLK
-error.
-.Sh RETURN VALUES
-Upon successful completion, the value returned depends on
-.Fa cmd
-as follows:
-.Bl -tag -width F_GETOWNX -offset indent
-.It Dv F_DUPFD
-A new file descriptor.
-.It Dv F_DUP2FD
-A file descriptor equal to
-.Fa arg .
-.It Dv F_GETFD
-Value of flag (only the low-order bit is defined).
-.It Dv F_GETFL
-Value of flags.
-.It Dv F_GETOWN
-Value of file descriptor owner.
-.It other
-Value other than -1.
-.El
-.Pp
-Otherwise, a value of -1 is returned and
-.Va errno
-is set to indicate the error.

-.Dt FLOCK 2
-.Os
-.Sh NAME
-.Nm flock
-.Nd "apply or remove an advisory lock on an open file"
-.Sh LIBRARY
-.Lb libc
-.Sh SYNOPSIS
-.In sys/file.h
-.Fd "#define LOCK_SH 0x01 /* shared file lock */"
-.Fd "#define LOCK_EX 0x02 /* exclusive file lock */"
-.Fd "#define LOCK_NB 0x04 /* do not block when locking */"
-.Fd "#define LOCK_UN 0x08 /* unlock file */"
-.Ft int
-.Fn flock "int fd" "int operation"
-.Sh DESCRIPTION
-The
-.Fn flock
-system call applies or removes an
-.Em advisory
-lock on the file associated with the file descriptor
-.Fa fd .
-A lock is applied by specifying an
-.Fa operation
-argument that is one of
-.Dv LOCK_SH
-or
-.Dv LOCK_EX
-with the optional addition of
-.Dv LOCK_NB .
-To unlock
-an existing lock
-.Dv operation
-should be
-.Dv LOCK_UN .
-.Pp
-Advisory locks allow cooperating processes to perform
-consistent operations on files, but do not guarantee
-consistency (i.e., processes may still access files
-without using advisory locks possibly resulting in
-inconsistencies).
-.Pp
-The locking mechanism allows two types of locks:
-.Em shared
-locks and
-.Em exclusive
-locks.
-At any time multiple shared locks may be applied to a file,
-but at no time are multiple exclusive, or both shared and exclusive,
-locks allowed simultaneously on a file.
-.Pp
-A shared lock may be
-.Em upgraded
-to an exclusive lock, and vice versa, simply by specifying
-the appropriate lock type; this results in the previous
-lock being released and the new lock applied (possibly
-after other processes have gained and released the lock).
-.Pp
-Requesting a lock on an object that is already locked
-normally causes the caller to be blocked until the lock may be
-acquired.
-If
-.Dv LOCK_NB
-is included in
-.Fa operation ,
-then this will not happen; instead the call will fail and
-the error
-.Er EWOULDBLOCK
-will be returned.
-.Sh NOTES
-Locks are on files, not file descriptors.
-That is, file descriptors
-duplicated through
-.Xr dup 2
-or
-.Xr fork 2
-do not result in multiple instances of a lock, but rather multiple
-references to a single lock.
-If a process holding a lock on a file
-forks and the child explicitly unlocks the file, the parent will
-lose its lock.
-.Pp
-The
-.Fn flock ,
-.Xr fcntl 2 ,
-and
-.Xr lockf 3
-locks are compatible.
-Processes using different locking interfaces can cooperate
-over the same file safely.
-However, only one of such interfaces should be used within
-the same process.
-If a file is locked by a process through
-.Fn flock ,
-any record within the file will be seen as locked
-from the viewpoint of another process using
-.Xr fcntl 2
-or
-.Xr lockf 3 ,
-and vice versa.
-.Pp
-Processes blocked awaiting a lock may be awakened by signals.
-.Sh RETURN VALUES
-.Rv -std flock
-.Sh ERRORS
-The
-.Fn flock
-system call fails if:
-.Bl -tag -width Er
-.It Bq Er EWOULDBLOCK
-The file is locked and the
-.Dv LOCK_NB
-option was specified.
-.It Bq Er EBADF
-The argument
-.Fa fd
-is an invalid descriptor.
-.It Bq Er EINVAL
-The argument
-.Fa fd
-refers to an object other than a file.

-.Ft pid_t
-.Fn fork void
-.Sh DESCRIPTION
-The
-.Fn fork
-system call causes creation of a new process.
-The new process (child process) is an exact copy of the
-calling process (parent process) except for the following:
-.Bl -bullet -offset indent
-.It
-The child process has a unique process ID.
-.It
-The child process has a different parent
-process ID (i.e., the process ID of the parent process).
-.It
-The child process has its own copy of the parent's descriptors.
-These descriptors reference the same underlying objects, so that,
-for instance, file pointers in file objects are shared between
-the child and the parent, so that an
-.Xr lseek 2
-on a descriptor in the child process can affect a subsequent
-.Xr read 2
-or
-.Xr write 2
-by the parent.
-This descriptor copying is also used by the shell to
-establish standard input and output for newly created processes
-as well as to set up pipes.
-.It
-The child process' resource utilizations
-are set to 0; see
-.Xr setrlimit 2 .
-.It
-All interval timers are cleared; see

-.El
-.Sh RETURN VALUES
-Upon successful completion,
-.Fn fork
-returns a value
-of 0 to the child process and returns the process ID of the child
-process to the parent process.
-Otherwise, a value of -1 is returned
-to the parent process, no child process is created, and the global
-variable
-.Va errno
-is set to indicate the error.
-.Sh ERRORS
-The
-.Fn fork
-system call will fail and no child process will be created if:

-.Sh NAME
-.Nm getdirentries ,

-.Nd "get directory entries in a file system independent format"
-.Sh LIBRARY
-.Lb libc
-.Sh SYNOPSIS
-.In sys/types.h
-.In dirent.h
-.Ft int
-.Fn getdirentries "int fd" "char *buf" "int nbytes" "long *basep"
-.Ft int
-.Fn getdents "int fd" "char *buf" "int nbytes"
-.Sh DESCRIPTION
-The
-.Fn getdirentries
-and
-.Fn getdents
-system calls read directory entries from the directory
-referenced by the file descriptor
-.Fa fd
-into the buffer pointed to by
-.Fa buf ,
-in a file system independent format.
-Up to
-.Fa nbytes
-of data will be transferred.
-The
-.Fa nbytes
-argument must be greater than or equal to the
-block size associated with the file,
-see
-.Xr stat 2 .
-Some file systems may not support these system calls
-with buffers smaller than this size.
-.Pp
-The data in the buffer is a series of
-.Vt dirent
-structures each containing the following entries:
-.Bd -literal -offset indent
-u_int32_t d_fileno;
-u_int16_t d_reclen;
-u_int8_t d_type;
-u_int8_t d_namlen;
-char d_name[MAXNAMELEN + 1]; /* see below */
-.Ed
-.Pp
-The
-.Fa d_fileno
-entry is a number which is unique for each
-distinct file in the file system.
-Files that are linked by hard links (see
-.Xr link 2 )
-have the same
-.Fa d_fileno .
-The
-.Fa d_reclen
-entry is the length, in bytes, of the directory record.
-The
-.Fa d_type
-entry is the type of the file pointed to by the directory record.
-The file type values are defined in
-.Fa <sys/dirent.h> .
-The
-.Fa d_name
-entry contains a null terminated file name.
-The
-.Fa d_namlen
-entry specifies the length of the file name excluding the null byte.
-Thus the actual size of
-.Fa d_name
-may vary from 1 to
-.Dv MAXNAMELEN
-\&+ 1.
-.Pp
-Entries may be separated by extra space.
-The
-.Fa d_reclen
-entry may be used as an offset from the start of a
-.Fa dirent
-structure to the next structure, if any.
-.Pp
-The actual number of bytes transferred is returned.
-The current position pointer associated with
-.Fa fd
-is set to point to the next block of entries.
-The pointer may not advance by the number of bytes returned by
-.Fn getdirentries
-or
-.Fn getdents .
-A value of zero is returned when
-the end of the directory has been reached.
-.Pp
-The
-.Fn getdirentries
-system call writes the position of the block read into the location pointed to by
-.Fa basep .
-Alternatively, the current position pointer may be set and retrieved by
-.Xr lseek 2 .
-The current position pointer should only be set to a value returned by
-.Xr lseek 2 ,
-a value returned in the location pointed to by
-.Fa basep
-.Fn ( getdirentries
-only)
-or zero.
-.Sh RETURN VALUES
-If successful, the number of bytes actually transferred is returned.
-Otherwise, -1 is returned and the global variable
-.Va errno
-is set to indicate the error.
-.Sh ERRORS
-The
-.Fn getdirentries
-system call
-will fail if:
-.Bl -tag -width Er
-.It Bq Er EBADF
-The
-.Fa fd
-argument
-is not a valid file descriptor open for reading.
-.It Bq Er EFAULT
-Either
-.Fa buf
-or

-point outside the allocated address space.
-.It Bq Er EINVAL
-The file referenced by
-.Fa fd
-is not a directory, or
-.Fa nbytes
-is too small for returning a directory entry or block of entries,
-or the current position pointer is invalid.

-.Os
-.Sh NAME
-.Nm getlogin ,
-.Nm getlogin_r ,
-.Nm setlogin
-.Nd get/set login name
-.Sh LIBRARY
-.Lb libc
-.Sh SYNOPSIS
-.In unistd.h
-.Ft char *
-.Fn getlogin void
-.In sys/param.h
-.Ft int
-.Fn getlogin_r "char *name" "int len"
-.Ft int
-.Fn setlogin "const char *name"
-.Sh DESCRIPTION
-The
-.Fn getlogin
-routine
-returns the login name of the user associated with the current session,
-as previously set by
-.Fn setlogin .
-The name is normally associated with a login shell
-at the time a session is created,
-and is inherited by all processes descended from the login shell.
-(This is true even if some of those processes assume another user ID,
-for example when
-.Xr su 1
-is used).
-.Pp
-The
-.Fn getlogin_r
-function
-provides the same service as
-.Fn getlogin
-except the caller must provide the buffer
-.Fa name
-with length
-.Fa len
-bytes
-to hold the result.
-The buffer should be at least
-.Dv MAXLOGNAME
-bytes in length.
-.Pp
-The
-.Fn setlogin
-system call
-sets the login name of the user associated with the current session to
-.Fa name .
-This system call is restricted to the super-user, and
-is normally used only when a new session is being created on behalf
-of the named user
-(for example, at login time, or when a remote shell is invoked).
-.Pp
-.Em NOTE :
-There is only one login name per session.
-.Pp
-It is
-.Em CRITICALLY
-important to ensure that
-.Fn setlogin
-is only ever called after the process has taken adequate steps to ensure
-that it is detached from its parent's session.
-Making a
-.Fn setsid
-system call is the
-.Em ONLY
-way to do this.
-The
-.Xr daemon 3
-function calls
-.Fn setsid
-which is an ideal way of detaching from a controlling terminal and
-forking into the background.
-.Pp
-In particular, doing a
-.Fn ioctl ttyfd TIOCNOTTY ...\&
-or
-.Fn setpgrp ...\&
-is
-.Em NOT
-sufficient.
-.Pp
-Once a parent process does a
-.Fn setsid
-system call, it is acceptable for some child of that process to then do a
-.Fn setlogin
-even though it is not the session leader, but beware that ALL processes
-in the session will change their login name at the same time, even the
-parent.
-.Pp
-This is not the same as the traditional UNIX behavior of inheriting privilege.
-.Pp
-Since the
-.Fn setlogin
-system call is restricted to the super-user, it is assumed that (like
-all other privileged programs) the programmer has taken adequate
-precautions to prevent security violations.
-.Sh RETURN VALUES
-If a call to
-.Fn getlogin
-succeeds, it returns a pointer to a null-terminated string in a static buffer,
-or
-.Dv NULL
-if the name has not been set.
-The
-.Fn getlogin_r
-function
-returns zero if successful, or the error number upon failure.
-.Pp
-.Rv -std setlogin
-.Sh ERRORS
-The following errors may be returned by these calls:
-.Bl -tag -width Er
-.It Bq Er EFAULT
-The
-.Fa name
-argument gave an
-invalid address.
-.It Bq Er EINVAL
-The
-.Fa name
-argument
-pointed to a string that was too long.
-Login names are limited to
-.Dv MAXLOGNAME
-(from
-.In sys/param.h )
-characters, currently 17 including null.
-.It Bq Er EPERM
-The caller tried to set the login name and was not the super-user.
-.It Bq Er ERANGE
-The size of the buffer is smaller than the result to be returned.
-.El
-.Sh SEE ALSO
-.Xr setsid 2 ,
-.Xr daemon 3
-.Sh STANDARDS
-The
-.Fn getlogin
-system call
-and
-the
-.Fn getlogin_r
-function
-conform to
-.St -p1003.1-96 .
-.Sh HISTORY
-The
-.Fn getlogin
-system call first appeared in
-.Bx 4.4 .
-The return value of
-.Fn getlogin_r
-was changed from earlier versions of
-.Fx
-to be conformant with
-.St -p1003.1-96 .
-.Sh BUGS
-In earlier versions of the system,
-.Fn getlogin
-failed unless the process was associated with a login terminal.
-The current implementation (using
-.Fn setlogin )
-allows getlogin to succeed even when the process has no controlling terminal.
-In earlier versions of the system, the value returned by
-.Fn getlogin
-could not be trusted without checking the user ID.
-Portable programs should probably still make this check.

-.Fn getpgrp void
-.Ft pid_t
-.Fn getpgid "pid_t pid"
-.Sh DESCRIPTION
-The process group of the current process is returned by
-.Fn getpgrp .
-The process group of the process identified by
-.Fa pid
-is returned by
-.Fn getpgid .
-If
-.Fa pid
-is zero,
-.Fn getpgid
-returns the process group of the current process.
-.Pp
-Process groups are used for distribution of signals, and
-by terminals to arbitrate requests for their input: processes
-that have the same process group as the terminal are foreground
-and may read, while others will block with a signal if they attempt
-to read.
-.Pp
-This system call is thus used by programs such as
-.Xr csh 1
-to create
-process groups
-in implementing job control.
-The
-.Fn tcgetpgrp
-and
-.Fn tcsetpgrp
-calls
-are used to get/set the process group of the control terminal.
-.Sh RETURN VALUES
-The
-.Fn getpgrp
-system call always succeeds.
-Upon successful completion, the
-.Fn getpgid
-system call returns the process group of the specified process;
-otherwise, it returns a value of \-1 and sets
-.Va errno
-to indicate the error.
-.Sh COMPATIBILITY
-This version of
-.Fn getpgrp
-differs from past Berkeley versions by not taking a
-.Fa "pid_t pid"
-argument.
-This incompatibility is required by
-.St -p1003.1-90 .
-.Pp
-From the
-.St -p1003.1-90
-Rationale:
-.Pp
-.Bx 4.3
-provides a
-.Fn getpgrp
-system call that returns the process group ID for a specified process.
-Although this function is used to support job control, all known
-job-control shells always specify the calling process with this
-function.
-Thus, the simpler
-.At V
-.Fn getpgrp
-suffices, and the added complexity of the
-.Bx 4.3
-.Fn getpgrp
-has been omitted from POSIX.1.
-The old functionality is available from the
-.Fn getpgid
-system call.
-.Sh ERRORS
-The
-.Fn getpgid
-system call
-will succeed unless:
-.Bl -tag -width Er
-.It Bq Er ESRCH

-.In sys/time.h
-.In sys/resource.h
-.Ft int
-.Fn getrlimit "int resource" "struct rlimit *rlp"
-.Ft int
-.Fn setrlimit "int resource" "const struct rlimit *rlp"
-.Sh DESCRIPTION
-Limits on the consumption of system resources by the current process
-and each process it creates may be obtained with the
-.Fn getrlimit
-system call, and set with the
-.Fn setrlimit
-system call.
-.Pp
-The
-.Fa resource
-argument is one of the following:
-.Bl -tag -width RLIMIT_FSIZEAA
-.It Dv RLIMIT_AS
-The maximum amount (in bytes) of virtual memory the process is
-allowed to map.
-.It Dv RLIMIT_CORE
-The largest size (in bytes)
-.Xr core 5
-file that may be created.
-.It Dv RLIMIT_CPU
-The maximum amount of cpu time (in seconds) to be used by
-each process.
-.It Dv RLIMIT_DATA
-The maximum size (in bytes) of the data segment for a process;
-this defines how far a program may extend its break with the
-.Xr sbrk 2
-function.
-.It Dv RLIMIT_FSIZE
-The largest size (in bytes) file that may be created.
-.It Dv RLIMIT_MEMLOCK
-The maximum size (in bytes) which a process may lock into memory
-using the
-.Xr mlock 2
-system call.
-.It Dv RLIMIT_NOFILE
-The maximum number of open files for this process.
-.It Dv RLIMIT_NPROC
-The maximum number of simultaneous processes for this user id.
-.It Dv RLIMIT_RSS
-The maximum size (in bytes) to which a process's resident set size may
-grow.
-This imposes a limit on the amount of physical memory to be given to
-a process; if memory is tight, the system will prefer to take memory
-from processes that are exceeding their declared resident set size.
-.It Dv RLIMIT_SBSIZE
-The maximum size (in bytes) of socket buffer usage for this user.
-This limits the amount of network memory, and hence the amount of
-mbufs, that this user may hold at any time.
-.It Dv RLIMIT_STACK
-The maximum size (in bytes) of the stack segment for a process;
-this defines how far a program's stack segment may be extended.
-Stack extension is performed automatically by the system.
-.It Dv RLIMIT_SWAP
-The maximum size (in bytes) of the swap space that may be reserved or
-used by all of this user id's processes.
-This limit is enforced only if bit 1 of the
-.Va vm.overcommit
-sysctl is set.
-Please see
-.Xr tuning 7
-for a complete description of this sysctl.
-.It Dv RLIMIT_NPTS
-The maximum number of pseudo-terminals created by this user id.
-.El
-.Pp
-A resource limit is specified as a soft limit and a hard limit.
-When a
-soft limit is exceeded a process may receive a signal (for example, if
-the cpu time or file size is exceeded), but it will be allowed to
-continue execution until it reaches the hard limit (or modifies
-its resource limit).
-The
-.Vt rlimit
-structure is used to specify the hard and soft limits on a resource,
-.Bd -literal -offset indent
-struct rlimit {
- rlim_t rlim_cur; /* current (soft) limit */
- rlim_t rlim_max; /* maximum value for rlim_cur */
-};
-.Ed
-.Pp
-Only the super-user may raise the maximum limits.
-Other users
-may only alter
-.Fa rlim_cur
-within the range from 0 to
-.Fa rlim_max
-or (irreversibly) lower
-.Fa rlim_max .
-.Pp
-An
-.Dq infinite
-value for a limit is defined as
-.Dv RLIM_INFINITY .
-.Pp
-Because this information is stored in the per-process information,
-this system call must be executed directly by the shell if it
-is to affect all future processes created by the shell;
-.Ic limit
-is thus a built-in command to
-.Xr csh 1 .
-.Pp
-The system refuses to extend the data or stack space when the limits
-would be exceeded in the normal way: a
-.Xr brk 2
-function fails if the data space limit is reached.
-When the stack limit is reached, the process receives
-a segmentation fault
-.Pq Dv SIGSEGV ;
-if this signal is not
-caught by a handler using the signal stack, this signal
-will kill the process.
-.Pp
-A file I/O operation that would create a file larger that the process'
-soft limit will cause the write to fail and a signal
-.Dv SIGXFSZ
-to be
-generated; this normally terminates the process, but may be caught.
-When
-the soft cpu time limit is exceeded, a signal
-.Dv SIGXCPU
-is sent to the
-offending process.
-.Sh RETURN VALUES
-.Rv -std
-.Sh ERRORS
-The
-.Fn getrlimit
-and
-.Fn setrlimit
-system calls
-will fail if:
-.Bl -tag -width Er
-.It Bq Er EFAULT
-The address specified for
-.Fa rlp
-is invalid.
-.It Bq Er EPERM
-The limit specified to
-.Fn setrlimit

-.Sh DESCRIPTION
-The
-.Fn getsockopt
-and
-.Fn setsockopt
-system calls
-manipulate the
-.Em options
-associated with a socket.
-Options may exist at multiple
-protocol levels; they are always present at the uppermost
-.Dq socket
-level.
-.Pp
-When manipulating socket options the level at which the
-option resides and the name of the option must be specified.
-To manipulate options at the socket level,
-.Fa level
-is specified as
-.Dv SOL_SOCKET .
-To manipulate options at any
-other level the protocol number of the appropriate protocol
-controlling the option is supplied.
-For example,
-to indicate that an option is to be interpreted by the
-.Tn TCP
-protocol,
-.Fa level
-should be set to the protocol number of
-.Tn TCP ;
-see
-.Xr getprotoent 3 .
-.Pp
-The
-.Fa optval
-and
-.Fa optlen
-arguments
-are used to access option values for
-.Fn setsockopt .
-For
-.Fn getsockopt
-they identify a buffer in which the value for the
-requested option(s) are to be returned.
-For
-.Fn getsockopt ,
-.Fa optlen
-is a value-result argument, initially containing the
-size of the buffer pointed to by
-.Fa optval ,
-and modified on return to indicate the actual size of
-the value returned.
-If no option value is
-to be supplied or returned,
-.Fa optval
-may be NULL.
-.Pp
-The
-.Fa optname
-argument
-and any specified options are passed uninterpreted to the appropriate
-protocol module for interpretation.
-The include file
-.In sys/socket.h
-contains definitions for
-socket level options, described below.
-Options at other protocol levels vary in format and
-name; consult the appropriate entries in
-section
-4 of the manual.
-.Pp
-Most socket-level options utilize an
-.Vt int
-argument for
-.Fa optval .
-For
-.Fn setsockopt ,
-the argument should be non-zero to enable a boolean option,
-or zero if the option is to be disabled.
-.Dv SO_LINGER
-uses a
-.Vt "struct linger"
-argument, defined in
-.In sys/socket.h ,
-which specifies the desired state of the option and the
-linger interval (see below).
-.Dv SO_SNDTIMEO
-and
-.Dv SO_RCVTIMEO
-use a
-.Vt "struct timeval"
-argument, defined in
-.In sys/time.h .
-.Pp
-The following options are recognized at the socket level.
-For protocol-specific options, see protocol manual pages,
-e.g.
-.Xr ip 4
-or
-.Xr tcp 4 .
-Except as noted, each may be examined with
-.Fn getsockopt

-.Pp
-.Dv SO_DEBUG
-enables debugging in the underlying protocol modules.
-.Dv SO_REUSEADDR
-indicates that the rules used in validating addresses supplied
-in a
-.Xr bind 2
-system call should allow reuse of local addresses.
-.Dv SO_REUSEPORT
-allows completely duplicate bindings by multiple processes
-if they all set
-.Dv SO_REUSEPORT
-before binding the port.
-This option permits multiple instances of a program to each
-receive UDP/IP multicast or broadcast datagrams destined for the bound port.
-.Dv SO_KEEPALIVE
-enables the
-periodic transmission of messages on a connected socket.
-Should the
-connected party fail to respond to these messages, the connection is
-considered broken and processes using the socket are notified via a
-.Dv SIGPIPE
-signal when attempting to send data.
-.Dv SO_DONTROUTE
-indicates that outgoing messages should
-bypass the standard routing facilities.
-Instead, messages are directed
-to the appropriate network interface according to the network portion
-of the destination address.
-.Pp
-.Dv SO_LINGER
-controls the action taken when unsent messages
-are queued on socket and a
-.Xr close 2
-is performed.
-If the socket promises reliable delivery of data and
-.Dv SO_LINGER
-is set,
-the system will block the process on the
-.Xr close 2
-attempt until it is able to transmit the data or until it decides it
-is unable to deliver the information (a timeout period, termed the
-linger interval, is specified in seconds in the
-.Fn setsockopt
-system call when
-.Dv SO_LINGER
-is requested).
-If
-.Dv SO_LINGER
-is disabled and a
-.Xr close 2
-is issued, the system will process the close in a manner that allows
-the process to continue as quickly as possible.
-.Pp
-The option
-.Dv SO_BROADCAST
-requests permission to send broadcast datagrams
-on the socket.
-Broadcast was a privileged operation in earlier versions of the system.
-With protocols that support out-of-band data, the
-.Dv SO_OOBINLINE
-option
-requests that out-of-band data be placed in the normal data input queue
-as received; it will then be accessible with
-.Xr recv 2
-or
-.Xr read 2
-calls without the
-.Dv MSG_OOB
-flag.
-Some protocols always behave as if this option is set.
-.Dv SO_SNDBUF
-and
-.Dv SO_RCVBUF
-are options to adjust the normal
-buffer sizes allocated for output and input buffers, respectively.
-The buffer size may be increased for high-volume connections,
-or may be decreased to limit the possible backlog of incoming data.
-The system places an absolute maximum on these values, which is accessible
-through the
-.Xr sysctl 3
-MIB variable
-.Dq Li kern.ipc.maxsockbuf .
-.Pp
-.Dv SO_SNDLOWAT
-is an option to set the minimum count for output operations.
-Most output operations process all of the data supplied
-by the call, delivering data to the protocol for transmission
-and blocking as necessary for flow control.
-Nonblocking output operations will process as much data as permitted
-subject to flow control without blocking, but will process no data
-if flow control does not allow the smaller of the low water mark value
-or the entire request to be processed.
-A
-.Xr select 2
-operation testing the ability to write to a socket will return true
-only if the low water mark amount could be processed.
-The default value for
-.Dv SO_SNDLOWAT
-is set to a convenient size for network efficiency, often 1024.
-.Dv SO_RCVLOWAT
-is an option to set the minimum count for input operations.
-In general, receive calls will block until any (non-zero) amount of data
-is received, then return with the smaller of the amount available or the amount
-requested.
-The default value for
-.Dv SO_RCVLOWAT
-is 1.
-If
-.Dv SO_RCVLOWAT
-is set to a larger value, blocking receive calls normally
-wait until they have received the smaller of the low water mark value
-or the requested amount.
-Receive calls may still return less than the low water mark if an error
-occurs, a signal is caught, or the type of data next in the receive queue
-is different from that which was returned.
-.Pp
-.Dv SO_SNDTIMEO
-is an option to set a timeout value for output operations.
-It accepts a
-.Vt "struct timeval"
-argument with the number of seconds and microseconds
-used to limit waits for output operations to complete.
-If a send operation has blocked for this much time,
-it returns with a partial count
-or with the error
-.Er EWOULDBLOCK
-if no data were sent.
-In the current implementation, this timer is restarted each time additional
-data are delivered to the protocol,
-implying that the limit applies to output portions ranging in size
-from the low water mark to the high water mark for output.
-.Dv SO_RCVTIMEO
-is an option to set a timeout value for input operations.
-It accepts a
-.Vt "struct timeval"
-argument with the number of seconds and microseconds
-used to limit waits for input operations to complete.
-In the current implementation, this timer is restarted each time additional
-data are received by the protocol,
-and thus the limit is in effect an inactivity timer.
-If a receive operation has been blocked for this much time without
-receiving additional data, it returns with a short count
-or with the error
-.Er EWOULDBLOCK
-if no data were received.
-.Pp
-.Dv SO_SETFIB
-can be used to over-ride the default FIB (routing table) for the given socket.
-The value must be from 0 to one less than the number returned from
-the sysctl
-.Em net.fibs .
-.Pp
-.Dv SO_ACCEPTFILTER
-places an
-.Xr accept_filter 9
-on the socket,
-which will filter incoming connections
-on a listening stream socket before being presented for
-.Xr accept 2 .
-Once more,
-.Xr listen 2
-must be called on the socket before
-trying to install the filter on it,
-or else the
-.Fn setsockopt
-system call will fail.
-.Bd -literal
-struct accept_filter_arg {
- char af_name[16];
- char af_arg[256-16];
-};
-.Ed
-.Pp
-The
-.Fa optval
-argument
-should point to a
-.Fa struct accept_filter_arg
-that will select and configure the
-.Xr accept_filter 9 .
-The
-.Fa af_name
-argument
-should be filled with the name of the accept filter
-that the application wishes to place on the listening socket.
-The optional argument
-.Fa af_arg
-can be passed to the accept
-filter specified by
-.Fa af_name
-to provide additional configuration options at attach time.
-Passing in an
-.Fa optval
-of NULL will remove the filter.
-.Pp
-The
-.Dv SO_NOSIGPIPE
-option controls generation of the
-.Dv SIGPIPE
-signal normally sent
-when writing to a connected socket where the other end has been
-closed returns with the error
-.Er EPIPE .
-.Pp
-If the
-.Dv SO_TIMESTAMP
-or
-.Dv SO_BINTIME
-option is enabled on a
-.Dv SOCK_DGRAM
-socket, the
-.Xr recvmsg 2
-call will return a timestamp corresponding to when the datagram was received.
-The
-.Va msg_control
-field in the
-.Vt msghdr
-structure points to a buffer that contains a
-.Vt cmsghdr
-structure followed by a
-.Vt "struct timeval"
-for
-.Dv SO_TIMESTAMP
-and
-.Vt "struct bintime"
-for
-.Dv SO_BINTIME .
-The
-.Vt cmsghdr
-fields have the following values for TIMESTAMP:
-.Bd -literal
- cmsg_len = sizeof(struct timeval);
- cmsg_level = SOL_SOCKET;
- cmsg_type = SCM_TIMESTAMP;
-.Ed
-.Pp
-and for
-.Dv SO_BINTIME :
-.Bd -literal
- cmsg_len = sizeof(struct bintime);
- cmsg_level = SOL_SOCKET;
- cmsg_type = SCM_BINTIME;
-.Ed
-.Pp
-.Dv SO_ACCEPTCONN ,
-.Dv SO_TYPE
-and
-.Dv SO_ERROR
-are options used only with
-.Fn getsockopt .
-.Dv SO_ACCEPTCONN
-returns whether the socket is currently accepting connections,
-that is, whether or not the
-.Xr listen 2
-system call was invoked on the socket.
-.Dv SO_TYPE
-returns the type of the socket, such as
-.Dv SOCK_STREAM ;
-it is useful for servers that inherit sockets on startup.
-.Dv SO_ERROR
-returns any pending error on the socket and clears
-the error status.
-It may be used to check for asynchronous errors on connected
-datagram sockets or for other asynchronous errors.
-.Pp
-Finally,
-.Dv SO_LABEL
-returns the MAC label of the socket.
-.Dv SO_PEERLABEL
-returns the MAC label of the socket's peer.
-Note that your kernel must be compiled with MAC support.
-See
-.Xr mac 3
-for more information.
-.Dv SO_LISTENQLIMIT
-returns the maximal number of queued connections, as set by
-.Xr listen 2 .
-.Dv SO_LISTENQLEN
-returns the number of unaccepted complete connections.
-.Dv SO_LISTENINCQLEN
-returns the number of unaccepted incomplete connections.

-.Sh DESCRIPTION
-.Bf -symbolic
-Note: timezone is no longer used; this information is kept outside
-the kernel.
-.Ef
-.Pp
-The system's notion of the current Greenwich time and the current time
-zone is obtained with the
-.Fn gettimeofday
-system call, and set with the
-.Fn settimeofday
-system call.
-The time is expressed in seconds and microseconds
-since midnight (0 hour), January 1, 1970.
-The resolution of the system
-clock is hardware dependent, and the time may be updated continuously or
-in
-.Dq ticks .
-If
-.Fa tp
-or
-.Fa tzp
-is NULL, the associated time
-information will not be returned or set.
-.Pp
-The structures pointed to by
-.Fa tp
-and
-.Fa tzp
-are defined in
-.In sys/time.h
-as:
-.Bd -literal
-struct timeval {
- time_t tv_sec; /* seconds */

-};
-
-struct timezone {
- int tz_minuteswest; /* minutes west of Greenwich */
- int tz_dsttime; /* type of dst correction */
-};
-.Ed
-.Pp
-The
-.Vt timezone
-structure indicates the local time zone
-(measured in minutes of time westward from Greenwich),
-and a flag that, if nonzero, indicates that
-Daylight Saving time applies locally during
-the appropriate part of the year.
-.Pp
-Only the super-user may set the time of day or time zone.
-If the system is running at securelevel >= 2 (see
-.Xr init 8 ) ,
-the time may only be advanced or retarded by a maximum of one second.
-This limitation is imposed to prevent a malicious super-user
-from setting arbitrary time stamps on files.
-The system time can be adjusted backwards without restriction using the
-.Xr adjtime 2
-system call even when the system is secure.

-.Dt INTRO 2
-.Os
-.Sh NAME
-.Nm intro
-.Nd introduction to system calls and error numbers
-.Sh LIBRARY
-.Lb libc
-.Sh SYNOPSIS
-.In errno.h
-.Sh DESCRIPTION
-This section provides an overview of the system calls,
-their error returns, and other common definitions and concepts.
-.\".Pp
-.\".Sy System call restart
-.\".Pp
-.\"(more later...)
-.Sh RETURN VALUES
-Nearly all of the system calls provide an error number referenced via
-the external identifier errno.
-This identifier is defined in
-.In sys/errno.h
-as
-.Pp
-.Dl extern int * __error();
-.Dl #define errno (* __error())
-.Pp
-The
-.Va __error()
-function returns a pointer to a field in the thread specific structure for
-threads other than the initial thread.
-For the initial thread and
-non-threaded processes,
-.Va __error()
-returns a pointer to a global
-.Va errno
-variable that is compatible with the previous definition.
-.Pp
-When a system call detects an error,
-it returns an integer value
-indicating failure (usually -1)
-and sets the variable
-.Va errno
-accordingly.
-(This allows interpretation of the failure on receiving
-a -1 and to take action accordingly.)
-Successful calls never set
-.Va errno ;
-once set, it remains until another error occurs.
-It should only be examined after an error.
-Note that a number of system calls overload the meanings of these
-error numbers, and that the meanings must be interpreted according
-to the type and circumstances of the call.
-.Pp
-The following is a complete list of the errors and their
-names as given in
-.In sys/errno.h .
-.Bl -hang -width Ds
-.It Er 0 Em "Undefined error: 0" .
-Not used.

-If the signal handler performs a normal return, the
-interrupted system call will seem to have returned the error condition.
-.It Er 5 EIO Em "Input/output error" .

-This error will not be reported until a subsequent operation on the same file
-descriptor and may be lost (over written) by any subsequent errors.
-.It Er 6 ENXIO Em "Device not configured" .
-Input or output on a special file referred to a device that did not
-exist, or
-made a request beyond the limits of the device.

-a tape drive is not online or no disk pack is
-loaded on a drive.
-.It Er 7 E2BIG Em "Argument list too long" .
-The number of bytes used for the argument and environment
-list of the new process exceeded the current limit

-that, although it has the appropriate permissions,
-was not in the format required for an
-executable file.
-.It Er 9 EBADF Em "Bad file descriptor" .
-A file descriptor argument was out of range, referred to no open file,
-or a read (write) request was made to a file that was only open for

-An attempt was made to lock a system resource that
-would have resulted in a deadlock situation.
-.It Er 12 ENOMEM Em "Cannot allocate memory" .
-The new process image required more memory than was allowed by the hardware
-or by system-imposed memory management constraints.
-A lack of swap space is normally temporary; however,
-a lack of core is not.
-Soft limits may be increased to their corresponding hard limits.
-.It Er 13 EACCES Em "Permission denied" .
-An attempt was made to access a file in a way forbidden
-by its file access permissions.
-.It Er 14 EFAULT Em "Bad address" .

-was attempted.
-.It Er 19 ENODEV Em "Operation not supported by device" .
-An attempt was made to apply an inappropriate
-function to a device,
-for example,
-trying to read a write-only device such as a printer.
-.It Er 20 ENOTDIR Em "Not a directory" .
-A component of the specified pathname existed, but it was
-not a directory, when a directory was expected.
-.It Er 21 EISDIR Em "Is a directory" .
-An attempt was made to open a directory with write mode specified.
-.It Er 22 EINVAL Em "Invalid argument" .
-Some invalid argument was supplied.
-(For example,
-specifying an undefined signal to a
-.Xr signal 3
-function
-or a
-.Xr kill 2
-system call).
-.It Er 23 ENFILE Em "Too many open files in system" .
-Maximum number of file descriptors allowable on the system
-has been reached and a requests for an open cannot be satisfied
-until at least one has been closed.
-.It Er 24 EMFILE Em "Too many open files" .
-(As released, the limit on the number of
-open files per process is 64.)
-The

-.Xr open 2
-call requested write access.
-.It Er 27 EFBIG Em "File too large" .
-The size of a file exceeded the maximum.
-.It Er 28 ENOSPC Em "No space left on device" .
-A
-.Xr write 2
-to an ordinary file, the creation of a
-directory or symbolic link, or the creation of a directory
-entry failed because no more disk blocks were available
-on the file system, or the allocation of an inode for a newly
-created file failed because no more inodes were available
-on the file system.
-.It Er 29 ESPIPE Em "Illegal seek" .
-An
-.Xr lseek 2
-system call was issued on a socket, pipe or
-.Tn FIFO .
-.It Er 30 EROFS Em "Read-only file system" .
-An attempt was made to modify a file or directory
-on a file system that was read-only at the time.
-.It Er 31 EMLINK Em "Too many links" .
-Maximum allowable hard links to a single file has been exceeded (limit
-of 32767 hard links per file).
-.It Er 32 EPIPE Em "Broken pipe" .
-A write on a pipe, socket or
-.Tn FIFO
-for which there is no process
-to read the data.
-.It Er 33 EDOM Em "Numerical argument out of domain" .
-A numerical input argument was outside the defined domain of the mathematical
-function.
-.It Er 34 ERANGE Em "Result too large" .
-A numerical result of the function was too large to fit in the
-available space (perhaps exceeded precision).
-.It Er 35 EAGAIN Em "Resource temporarily unavailable" .

-.El
-.Sh DEFINITIONS
-.Bl -tag -width Ds
-.It Process ID .
-Each active process in the system is uniquely identified by a non-negative
-integer called a process ID.
-The range of this ID is from 0 to 99999.
-.It Parent process ID
-A new process is created by a currently active process (see
-.Xr fork 2 ) .
-The parent process ID of a process is initially the process ID of its creator.
-If the creating process exits,
-the parent process ID of each child is set to the ID of a system process,
-.Xr init 8 .
-.It Process Group
-Each active process is a member of a process group that is identified by
-a non-negative integer called the process group ID.
-This is the process
-ID of the group leader.
-This grouping permits the signaling of related
-processes (see
-.Xr termios 4 )
-and the job control mechanisms of
-.Xr csh 1 .
-.It Session
-A session is a set of one or more process groups.
-A session is created by a successful call to
-.Xr setsid 2 ,
-which causes the caller to become the only member of the only process
-group in the new session.
-.It Session leader
-A process that has created a new session by a successful call to
-.Xr setsid 2 ,
-is known as a session leader.
-Only a session leader may acquire a terminal as its controlling terminal (see
-.Xr termios 4 ) .
-.It Controlling process
-A session leader with a controlling terminal is a controlling process.
-.It Controlling terminal
-A terminal that is associated with a session is known as the controlling
-terminal for that session and its members.
-.It "Terminal Process Group ID"
-A terminal may be acquired by a session leader as its controlling terminal.
-Once a terminal is associated with a session, any of the process groups
-within the session may be placed into the foreground by setting
-the terminal process group ID to the ID of the process group.
-This facility is used
-to arbitrate between multiple jobs contending for the same terminal;
-(see
-.Xr csh 1
-and
-.Xr tty 4 ) .
-.It "Orphaned Process Group"
-A process group is considered to be
-.Em orphaned
-if it is not under the control of a job control shell.
-More precisely, a process group is orphaned
-when none of its members has a parent process that is in the same session
-as the group,
-but is in a different process group.
-Note that when a process exits, the parent process for its children
-is changed to be
-.Xr init 8 ,
-which is in a separate session.
-Not all members of an orphaned process group are necessarily orphaned
-processes (those whose creating process has exited).
-The process group of a session leader is orphaned by definition.
-.It "Real User ID and Real Group ID"
-Each user on the system is identified by a positive integer
-termed the real user ID.
-.Pp
-Each user is also a member of one or more groups.
-One of these groups is distinguished from others and
-used in implementing accounting facilities.
-The positive
-integer corresponding to this distinguished group is termed
-the real group ID.
-.Pp
-All processes have a real user ID and real group ID.
-These are initialized from the equivalent attributes
-of the process that created it.
-.It "Effective User Id, Effective Group Id, and Group Access List"
-Access to system resources is governed by two values:
-the effective user ID, and the group access list.
-The first member of the group access list is also known as the
-effective group ID.
-(In POSIX.1, the group access list is known as the set of supplementary
-group IDs, and it is unspecified whether the effective group ID is
-a member of the list.)
-.Pp
-The effective user ID and effective group ID are initially the
-process's real user ID and real group ID respectively.
-Either
-may be modified through execution of a set-user-ID or set-group-ID
-file (possibly by one its ancestors) (see
-.Xr execve 2 ) .
-By convention, the effective group ID (the first member of the group access
-list) is duplicated, so that the execution of a set-group-ID program
-does not result in the loss of the original (real) group ID.
-.Pp
-The group access list is a set of group IDs
-used only in determining resource accessibility.
-Access checks
-are performed as described below in ``File Access Permissions''.
-.It "Saved Set User ID and Saved Set Group ID"
-When a process executes a new file, the effective user ID is set
-to the owner of the file if the file is set-user-ID, and the effective
-group ID (first element of the group access list) is set to the group
-of the file if the file is set-group-ID.
-The effective user ID of the process is then recorded as the saved set-user-ID,
-and the effective group ID of the process is recorded as the saved set-group-ID.
-These values may be used to regain those values as the effective user
-or group ID after reverting to the real ID (see
-.Xr setuid 2 ) .
-(In POSIX.1, the saved set-user-ID and saved set-group-ID are optional,
-and are used in setuid and setgid, but this does not work as desired
-for the super-user.)
-.It Super-user
-A process is recognized as a
-.Em super-user
-process and is granted special privileges if its effective user ID is 0.
-.It Descriptor
-An integer assigned by the system when a file is referenced
-by
-.Xr open 2
-or
-.Xr dup 2 ,
-or when a socket is created by
-.Xr pipe 2 ,
-.Xr socket 2
-or
-.Xr socketpair 2 ,
-which uniquely identifies an access path to that file or socket from
-a given process or any of its children.
-.It File Name
-Names consisting of up to
-.Brq Dv NAME_MAX
-characters may be used to name
-an ordinary file, special file, or directory.
-.Pp
-These characters may be arbitrary eight-bit values,
-excluding
-.Dv NUL
-.Tn ( ASCII
-0) and the
-.Ql \&/
-character (slash,
-.Tn ASCII
-47).
-.Pp
-Note that it is generally unwise to use
-.Ql \&* ,
-.Ql \&? ,
-.Ql \&[
-or
-.Ql \&]
-as part of
-file names because of the special meaning attached to these characters
-by the shell.
-.It Path Name
-A path name is a
-.Dv NUL Ns -terminated
-character string starting with an
-optional slash
-.Ql \&/ ,
-followed by zero or more directory names separated
-by slashes, optionally followed by a file name.
-The total length of a path name must be less than
-.Brq Dv PATH_MAX
-characters.
-(On some systems, this limit may be infinite.)
-.Pp
-If a path name begins with a slash, the path search begins at the
-.Em root
-directory.
-Otherwise, the search begins from the current working directory.
-A slash by itself names the root directory.
-An empty
-pathname refers to the current directory.
-.It Directory
-A directory is a special type of file that contains entries
-that are references to other files.
-Directory entries are called links.
-By convention, a directory
-contains at least two links,
-.Ql .\&
-and
-.Ql \&.. ,
-referred to as
-.Em dot
-and
-.Em dot-dot
-respectively.
-Dot refers to the directory itself and
-dot-dot refers to its parent directory.
-.It "Root Directory and Current Working Directory"
-Each process has associated with it a concept of a root directory
-and a current working directory for the purpose of resolving path
-name searches.
-A process's root directory need not be the root
-directory of the root file system.
-.It File Access Permissions
-Every file in the file system has a set of access permissions.
-These permissions are used in determining whether a process
-may perform a requested operation on the file (such as opening
-a file for writing).
-Access permissions are established at the
-time a file is created.
-They may be changed at some later time
-through the
-.Xr chmod 2
-call.
-.Pp
-File access is broken down according to whether a file may be: read,
-written, or executed.
-Directory files use the execute
-permission to control if the directory may be searched.
-.Pp
-File access permissions are interpreted by the system as
-they apply to three different classes of users: the owner
-of the file, those users in the file's group, anyone else.
-Every file has an independent set of access permissions for
-each of these classes.
-When an access check is made, the system
-decides if permission should be granted by checking the access
-information applicable to the caller.
-.Pp
-Read, write, and execute/search permissions on
-a file are granted to a process if:
-.Pp
-The process's effective user ID is that of the super-user.
-(Note:
-even the super-user cannot execute a non-executable file.)
-.Pp
-The process's effective user ID matches the user ID of the owner
-of the file and the owner permissions allow the access.
-.Pp
-The process's effective user ID does not match the user ID of the
-owner of the file, and either the process's effective
-group ID matches the group ID
-of the file, or the group ID of the file is in
-the process's group access list,
-and the group permissions allow the access.
-.Pp
-Neither the effective user ID nor effective group ID
-and group access list of the process
-match the corresponding user ID and group ID of the file,
-but the permissions for ``other users'' allow access.
-.Pp
-Otherwise, permission is denied.
-.It Sockets and Address Families
-A socket is an endpoint for communication between processes.
-Each socket has queues for sending and receiving data.
-.Pp
-Sockets are typed according to their communications properties.
-These properties include whether messages sent and received
-at a socket require the name of the partner, whether communication
-is reliable, the format used in naming message recipients, etc.
-.Pp
-Each instance of the system supports some
-collection of socket types; consult
-.Xr socket 2
-for more information about the types available and
-their properties.
-.Pp
-Each instance of the system supports some number of sets of
-communications protocols.
-Each protocol set supports addresses
-of a certain format.
-An Address Family is the set of addresses
-for a specific group of protocols.
-Each socket has an address
-chosen from the address family in which the socket was created.

-.Sh NAME
-.Nm ioctl
-.Nd control device
-.Sh LIBRARY
-.Lb libc
-.Sh SYNOPSIS
-.In sys/ioctl.h
-.Ft int
-.Fn ioctl "int d" "unsigned long request" ...
-.Sh DESCRIPTION
-The
-.Fn ioctl
-system call manipulates the underlying device parameters of special files.
-In particular, many operating
-characteristics of character special files (e.g.\& terminals)
-may be controlled with
-.Fn ioctl
-requests.
-The argument
-.Fa d
-must be an open file descriptor.
-.Pp
-The third argument to
-.Fn ioctl
-is traditionally named
-.Va "char *argp" .
-Most uses of
-.Fn ioctl ,
-however, require the third argument to be a
-.Vt caddr_t
-or an
-.Vt int .
-.Pp
-An
-.Fn ioctl
-.Fa request
-has encoded in it whether the argument is an
-.Dq in
-argument
-or
-.Dq out
-argument, and the size of the argument
-.Fa argp
-in bytes.
-Macros and defines used in specifying an ioctl
-.Fa request
-are located in the file
-.In sys/ioctl.h .
-.Sh GENERIC IOCTLS
-Some generic ioctls are not implemented for all types of file
-descriptors.
-These include:
-.Bl -tag -width "xxxxxx"
-.It Dv FIONREAD int
-Get the number of bytes that are immediately available for reading.
-.It Dv FIONWRITE int
-Get the number of bytes in the descriptor's send queue.
-These bytes are data which has been written to the descriptor but
-which are being held by the kernel for further processing.
-The nature of the required processing depends on the underlying device.
-For TCP sockets, these bytes have not yet been acknowledged by the
-other side of the connection.
-.It Dv FIONSPACE int
-Get the free space in the descriptor's send queue.
-This value is the size of the send queue minus the number of bytes
-being held in the queue.
-Note: while this value represents the number of bytes that may be
-added to the queue, other resource limitations may cause a write
-not larger than the send queue's space to be blocked.
-One such limitation would be a lack of network buffers for a write
-to a network connection.
-.El
-.Sh RETURN VALUES
-If an error has occurred, a value of -1 is returned and
-.Va errno
-is set to indicate the error.
-.Sh ERRORS
-The
-.Fn ioctl
-system call
-will fail if:
-.Bl -tag -width Er
-.It Bq Er EBADF
-The
-.Fa d
-argument
-is not a valid descriptor.
-.It Bq Er ENOTTY
-The
-.Fa d
-argument
-is not associated with a character
-special device.
-.It Bq Er ENOTTY
-The specified request does not apply to the kind

-.Os
-.Sh NAME
-.Nm issetugid
-.Nd is current process tainted by uid or gid changes
-.Sh LIBRARY
-.Lb libc
-.Sh SYNOPSIS
-.In unistd.h
-.Ft int
-.Fn issetugid void
-.Sh DESCRIPTION
-The
-.Fn issetugid
-system call returns 1 if the process environment or memory address space
-is considered
-.Dq tainted ,
-and returns 0 otherwise.
-.Pp
-A process is tainted if it was created as a result of an
-.Xr execve 2
-system call which had either of the setuid or setgid bits set (and extra
-privileges were given as a result) or if it has changed any of its real,
-effective or saved user or group ID's since it began execution.
-.Pp
-This system call exists so that library routines (eg: libc, libtermcap)
-can reliably determine if it is safe to use information
-that was obtained from the user, in particular the results from
-.Xr getenv 3
-should be viewed with suspicion if it is used to control operation.
-.Pp
-A
-.Dq tainted
-status is inherited by child processes as a result of the
-.Xr fork 2
-system call (or other library code that calls fork, such as
-.Xr popen 3 ) .
-.Pp
-It is assumed that a program that clears all privileges as it prepares
-to execute another will also reset the environment, hence the
-.Dq tainted
-status will not be passed on.
-This is important for programs such as
-.Xr su 1
-which begin setuid but need to be able to create an untainted process.
-.Sh ERRORS
-The
-.Fn issetugid
-system call is always successful, and no return value is reserved to
-indicate an error.

-.Xr setuid 2
-.Sh HISTORY
-The
-.Fn issetugid
-system call first appeared in
-.Ox 2.0

-.Sh LIBRARY
-.Lb libc
-.Sh SYNOPSIS
-.In sys/param.h
-.In sys/jail.h
-.Ft int
-.Fn jail "struct jail *jail"
-.Ft int
-.Fn jail_attach "int jid"
-.Ft int
-.Fn jail_remove "int jid"

-.Ft int
-.Fn jail_get "struct iovec *iov" "u_int niov" "int flags"
-.Ft int
-.Fn jail_set "struct iovec *iov" "u_int niov" "int flags"
-.Sh DESCRIPTION
-The
-.Fn jail
-system call sets up a jail and locks the current process in it.
-.Pp
-The argument is a pointer to a structure describing the prison:
-.Bd -literal -offset indent
-struct jail {
- u_int32_t version;
- char *path;
- char *hostname;
- char *jailname;
- unsigned int ip4s;
- unsigned int ip6s;
- struct in_addr *ip4;
- struct in6_addr *ip6;
-};
-.Ed
-.Pp
-.Dq Li version
-defines the version of the API in use.
-.Dv JAIL_API_VERSION
-is defined for the current version.
-.Pp
-The
-.Dq Li path
-pointer should be set to the directory which is to be the root of the
-prison.
-.Pp
-The
-.Dq Li hostname
-pointer can be set to the hostname of the prison.
-This can be changed
-from the inside of the prison.
-.Pp
-The
-.Dq Li jailname
-pointer is an optional name that can be assigned to the jail
-for example for management purposes.
-.Pp
-The
-.Dq Li ip4s
-and
-.Dq Li ip6s
-give the numbers of IPv4 and IPv6 addresses that will be passed
-via their respective pointers.
-.Pp
-The
-.Dq Li ip4
-and
-.Dq Li ip6
-pointers can be set to an arrays of IPv4 and IPv6 addresses to be assigned to
-the prison, or NULL if none.
-IPv4 addresses must be in network byte order.
-.Pp
-This is equivalent to the
-.Fn jail_set
-system call (see below), with the parameters
-.Va path ,
-.Va host.hostname ,
-.Va name ,
-.Va ip4.addr ,
-and
-.Va ip6.addr ,
-and with the
-.Dv JAIL_ATTACH
-flag.
-.Pp
-The
-.Fn jail_set
-system call creates a new jail, or modifies an existing one, and optionally
-locks the current process in it.
-Jail parameters are passed as an array of name-value pairs in the array
-.Fa iov ,
-containing
-.Fa niov
-elements.
-Parameter names are a null-terminated string, and values may be strings,
-integers, or other arbitrary data.
-Some parameters are boolean, and do not have a value (their length is zero)
-but are set by the name alone with or without a
-.Dq no
-prefix, e.g.
-.Va persist
-or
-.Va nopersist .
-Any parameters not set will be given default values, generally based on
-the current environment.
-.Pp
-Jails have a set of core parameters, and modules can add their own jail
-parameters.
-The current set of available parameters, and their formats, can be
-retrieved via the
-.Va security.jail.param
-sysctl MIB entry.
-Notable parameters include those mentioned in the
-.Fn jail
-description above, as well as
-.Va jid
-and
-.Va name ,
-which identify the jail being created or modified.
-See
-.Xr jail 8
-for more information on the core jail parameters.
-.Pp
-The
-.Fa flags
-arguments consists of one or more of the following flags:
-.Bl -tag -width indent
-.It Dv JAIL_CREATE
-Create a new jail.
-If a
-.Va jid
-or
-.Va name
-parameters exists, they must not refer to an existing jail.
-.It Dv JAIL_UPDATE
-Modify an existing jail.
-One of the
-.Va jid
-or
-.Va name
-parameters must exist, and must refer to an existing jail.
-If both
-.Dv JAIL_CREATE
-and
-.Dv JAIL_UPDATE
-are set, a jail will be created if it does not yet exist, and modified if it
-does exist.
-.It Dv JAIL_ATTACH
-In addition to creating or modifying the jail, attach the current process to
-it, as with the
-.Fn jail_attach
-system call.
-.It Dv JAIL_DYING
-Allow setting a jail that is in the process of being removed.
-.El
-.Pp
-The
-.Fn jail_get
-system call retrieves jail parameters, using the same name-value list as
-.Fn jail_set
-in the
-.Fa iov
-and
-.Fa niov
-arguments.
-The jail to read can be specified by either
-.Va jid
-or
-.Va name
-by including those parameters in the list.
-If they are included but are not intended to be the search key, they
-should be cleared (zero and the empty string respectively).
-.Pp
-The special parameter
-.Va lastjid
-can be used to retrieve a list of all jails.
-It will fetch the jail with the jid above and closest to the passed value.
-The first jail (usually but not always jid 1) can be found by passing a
-.Va lastjid
-of zero.
-.Pp
-The
-.Fa flags
-arguments consists of one or more following flags:
-.Bl -tag -width indent
-.It Dv JAIL_DYING
-Allow getting a jail that is in the process of being removed.
-.El
-.Pp
-The
-.Fn jail_attach
-system call attaches the current process to an existing jail,
-identified by
-.Fa jid .
-.Pp
-The
-.Fn jail_remove
-system call removes the jail identified by
-.Fa jid .
-It will kill all processes belonging to the jail, and remove any children
-of that jail.
-.Sh RETURN VALUES
-If successful,
-.Fn jail ,
-.Fn jail_set ,
-and
-.Fn jail_get
-return a non-negative integer, termed the jail identifier (JID).
-They return \-1 on failure, and set
-.Va errno
-to indicate the error.
-.Pp
-.Rv -std jail_attach jail_remove
-.Sh PRISON?
-Once a process has been put in a prison, it and its descendants cannot escape
-the prison.
-.Pp
-Inside the prison, the concept of
-.Dq superuser
-is very diluted.
-In general,
-it can be assumed that nothing can be mangled from inside a prison which
-does not exist entirely inside that prison.
-For instance the directory
-tree below
-.Dq Li path
-can be manipulated all the ways a root can normally do it, including
-.Dq Li "rm -rf /*"
-but new device special nodes cannot be created because they reference
-shared resources (the device drivers in the kernel).
-The effective
-.Dq securelevel
-for a process is the greater of the global
-.Dq securelevel
-or, if present, the per-jail
-.Dq securelevel .
-.Pp
-All IP activity will be forced to happen to/from the IP number specified,
-which should be an alias on one of the network interfaces.
-All connections to/from the loopback address
-.Pf ( Li 127.0.0.1
-for IPv4,
-.Li ::1
-for IPv6) will be changed to be to/from the primary address
-of the jail for the given address family.
-.Pp
-It is possible to identify a process as jailed by examining
-.Dq Li /proc/<pid>/status :
-it will show a field near the end of the line, either as
-a single hyphen for a process at large, or the name currently
-set for the prison for jailed processes.
-.Sh ERRORS
-The
-.Fn jail
-system call
-will fail if:
-.Bl -tag -width Er

-.Ft int
-.Fn kill "pid_t pid" "int sig"
-.Sh DESCRIPTION
-The
-.Fn kill
-system call sends the signal given by
-.Fa sig
-to
-.Fa pid ,
-a
-process or a group of processes.
-The
-.Fa sig
-argument
-may be one of the signals specified in
-.Xr sigaction 2
-or it may be 0, in which case
-error checking is performed but no
-signal is actually sent.
-This can be used to check the validity of
-.Fa pid .
-.Pp
-For a process to have permission to send a signal to a process designated
-by
-.Fa pid ,
-the real or effective user ID of the receiving process must match
-that of the sending process or the user must have appropriate privileges
-(such as given by a set-user-ID program or the user is the super-user).
-A single exception is the signal SIGCONT, which may always be sent
-to any process with the same session ID as the caller.
-.Bl -tag -width Ds
-.It \&If Fa pid No \&is greater than zero :
-The
-.Fa sig
-signal
-is sent to the process whose ID is equal to
-.Fa pid .
-.It \&If Fa pid No \&is zero :
-The
-.Fa sig
-signal
-is sent to all processes whose group ID is equal
-to the process group ID of the sender, and for which the
-process has permission;
-this is a variant of
-.Xr killpg 2 .
-.It \&If Fa pid No \&is -1 :
-If the user has super-user privileges,
-the signal is sent to all processes excluding
-system processes
-(with
-.Dv P_SYSTEM
-flag set),
-process with ID 1
-(usually
-.Xr init 8 ) ,
-and the process sending the signal.
-If the user is not the super user, the signal is sent to all processes
-with the same uid as the user excluding the process sending the signal.
-No error is returned if any process could be signaled.
-.El
-.Pp
-For compatibility with System V,
-if the process number is negative but not -1,
-the signal is sent to all processes whose process group ID
-is equal to the absolute value of the process number.
-This is a variant of
-.Xr killpg 2 .
-.Sh RETURN VALUES
-.Rv -std kill
-.Sh ERRORS
-The
-.Fn kill

-.It Bq Er ESRCH
-No process can be found corresponding to that specified by

-.It Bq Er ESRCH
-The process id was given as 0
-but the sending process does not have a process group.
-.It Bq Er EPERM
-The sending process is not the super-user and its effective

-.Dt KQUEUE 2
-.Os
-.Sh NAME
-.Nm kqueue ,
-.Nm kevent
-.Nd kernel event notification mechanism
-.Sh LIBRARY
-.Lb libc
-.Sh SYNOPSIS
-.In sys/types.h
-.In sys/event.h
-.In sys/time.h
-.Ft int
-.Fn kqueue "void"
-.Ft int
-.Fn kevent "int kq" "const struct kevent *changelist" "int nchanges" "struct kevent *eventlist" "int nevents" "const struct timespec *timeout"
-.Fn EV_SET "&kev" ident filter flags fflags data udata
-.Sh DESCRIPTION
-The
-.Fn kqueue
-system call
-provides a generic method of notifying the user when an event
-happens or a condition holds, based on the results of small
-pieces of kernel code termed filters.
-A kevent is identified by the (ident, filter) pair; there may only
-be one unique kevent per kqueue.
-.Pp
-The filter is executed upon the initial registration of a kevent
-in order to detect whether a preexisting condition is present, and is also
-executed whenever an event is passed to the filter for evaluation.
-If the filter determines that the condition should be reported,
-then the kevent is placed on the kqueue for the user to retrieve.
-.Pp
-The filter is also run when the user attempts to retrieve the kevent
-from the kqueue.
-If the filter indicates that the condition that triggered
-the event no longer holds, the kevent is removed from the kqueue and
-is not returned.
-.Pp
-Multiple events which trigger the filter do not result in multiple
-kevents being placed on the kqueue; instead, the filter will aggregate
-the events into a single struct kevent.
-Calling
-.Fn close
-on a file descriptor will remove any kevents that reference the descriptor.
-.Pp
-The
-.Fn kqueue
-system call
-creates a new kernel event queue and returns a descriptor.
-The queue is not inherited by a child created with
-.Xr fork 2 .
-However, if
-.Xr rfork 2
-is called without the
-.Dv RFFDG
-flag, then the descriptor table is shared,
-which will allow sharing of the kqueue between two processes.
-.Pp
-The
-.Fn kevent
-system call
-is used to register events with the queue, and return any pending
-events to the user.
-The
-.Fa changelist
-argument
-is a pointer to an array of
-.Va kevent
-structures, as defined in
-.In sys/event.h .
-All changes contained in the
-.Fa changelist
-are applied before any pending events are read from the queue.
-The
-.Fa nchanges
-argument
-gives the size of
-.Fa changelist .
-The
-.Fa eventlist
-argument
-is a pointer to an array of kevent structures.
-The
-.Fa nevents
-argument
-determines the size of
-.Fa eventlist .
-When
-.Fa nevents
-is zero,
-.Fn kevent
-will return immediately even if there is a
-.Fa timeout
-specified unlike
-.Xr select 2 .
-If
-.Fa timeout
-is a non-NULL pointer, it specifies a maximum interval to wait
-for an event, which will be interpreted as a struct timespec.
-If
-.Fa timeout
-is a NULL pointer,
-.Fn kevent
-waits indefinitely.
-To effect a poll, the
-.Fa timeout
-argument should be non-NULL, pointing to a zero-valued
-.Va timespec
-structure.
-The same array may be used for the
-.Fa changelist
-and
-.Fa eventlist .
-.Pp
-The
-.Fn EV_SET
-macro is provided for ease of initializing a
-kevent structure.
-.Pp
-The
-.Va kevent
-structure is defined as:
-.Bd -literal
-struct kevent {
- uintptr_t ident; /* identifier for this event */
- short filter; /* filter for event */
- u_short flags; /* action flags for kqueue */
- u_int fflags; /* filter flag value */

-field can contain the following values:
-.Bl -tag -width XXXEV_ONESHOT
-.It EV_ADD
-Adds the event to the kqueue.
-Re-adding an existing event
-will modify the parameters of the original event, and not result
-in a duplicate entry.
-Adding an event automatically enables it,
-unless overridden by the EV_DISABLE flag.
-.It EV_ENABLE
-Permit
-.Fn kevent
-to return the event if it is triggered.
-.It EV_DISABLE
-Disable the event so
-.Fn kevent
-will not return it.
-The filter itself is not disabled.
-.It EV_DISPATCH
-Disable the event source immediately after delivery of an event.
-See
-.Dv EV_DISABLE
-above.
-.It EV_DELETE
-Removes the event from the kqueue.
-Events which are attached to
-file descriptors are automatically deleted on the last close of
-the descriptor.
-.It EV_RECEIPT
-This flag is useful for making bulk changes to a kqueue without draining
-any pending events.
-When passed as input, it forces
-.Dv EV_ERROR
-to always be returned.
-When a filter is successfully added the
-.Va data
-field will be zero.
-.It EV_ONESHOT
-Causes the event to return only the first occurrence of the filter
-being triggered.
-After the user retrieves the event from the kqueue,
-it is deleted.
-.It EV_CLEAR
-After the event is retrieved by the user, its state is reset.
-This is useful for filters which report state transitions
-instead of the current state.
-Note that some filters may automatically
-set this flag internally.
-.It EV_EOF
-Filters may set this flag to indicate filter-specific EOF condition.

-and
-.Va data
-fields in the kevent structure.
-.Bl -tag -width EVFILT_SIGNAL
-.It EVFILT_READ
-Takes a descriptor as the identifier, and returns whenever
-there is data available to read.
-The behavior of the filter is slightly different depending
-on the descriptor type.
-.Bl -tag -width 2n
-.It Sockets
-Sockets which have previously been passed to
-.Fn listen
-return when there is an incoming connection pending.
-.Va data
-contains the size of the listen backlog.
-.Pp
-Other socket descriptors return when there is data to be read,
-subject to the
-.Dv SO_RCVLOWAT
-value of the socket buffer.
-This may be overridden with a per-filter low water mark at the
-time the filter is added by setting the
-NOTE_LOWAT
-flag in
-.Va fflags ,
-and specifying the new low water mark in
-.Va data .
-On return,
-.Va data
-contains the number of bytes of protocol data available to read.
-.Pp
-If the read direction of the socket has shutdown, then the filter
-also sets EV_EOF in
-.Va flags ,
-and returns the socket error (if any) in
-.Va fflags .
-It is possible for EOF to be returned (indicating the connection is gone)
-while there is still data pending in the socket buffer.

-Returns when the file pointer is not at the end of file.
-.Va data
-contains the offset from current position to end of file,
-and may be negative.
-.It "Fifos, Pipes"
-Returns when the there is data to read;
-.Va data
-contains the number of bytes available.
-.Pp
-When the last writer disconnects, the filter will set EV_EOF in

-This may be cleared by passing in EV_CLEAR, at which point the
-filter will resume waiting for data to become available before
-returning.
-.It "BPF devices"
-Returns when the BPF buffer is full, the BPF timeout has expired, or

-.El
-.It EVFILT_WRITE
-Takes a descriptor as the identifier, and returns whenever
-it is possible to write to the descriptor.
-For sockets, pipes
-and fifos,
-.Va data
-will contain the amount of space remaining in the write buffer.
-The filter will set EV_EOF when the reader disconnects, and for
-the fifo case, this may be cleared by use of EV_CLEAR.
-Note that this filter is not supported for vnodes or BPF devices.
-.Pp
-For sockets, the low water mark and socket error handling is
-identical to the EVFILT_READ case.
-.It EVFILT_AIO
-The sigevent portion of the AIO request is filled in, with
-.Va sigev_notify_kqueue
-containing the descriptor of the kqueue that the event should
-be attached to,

-.Sh DESCRIPTION
-These system calls implement kernel support for multi-threaded processes.
-.\"
-.Ss Overview
-.\"
-Traditionally, user threading has been implemented in one of two ways:
-either all threads are managed in user space and the kernel is unaware
-of any threading (also known as
-.Dq "N to 1" ) ,
-or else separate processes sharing
-a common memory space are created for each thread (also known as
-.Dq "N to N" ) .
-These approaches have advantages and disadvantages:
-.Bl -column "- Cannot utilize multiple CPUs" "+ Can utilize multiple CPUs"
-.It Sy "User threading Kernel threading"
-.It "+ Lightweight - Heavyweight"
-.It "+ User controls scheduling - Kernel controls scheduling"
-.It "- Syscalls must be wrapped + No syscall wrapping required"
-.It "- Cannot utilize multiple CPUs + Can utilize multiple CPUs"
-.El
-.Pp
-The KSE system is a
-hybrid approach that achieves the advantages of both the user and kernel
-threading approaches.
-The underlying philosophy of the KSE system is to give kernel support
-for user threading without taking away any of the user threading library's
-ability to make scheduling decisions.
-A kernel-to-user upcall mechanism is used to pass control to the user
-threading library whenever a scheduling decision needs to be made.
-An arbitrarily number of user threads are multiplexed onto a fixed number of
-virtual CPUs supplied by the kernel.
-This can be thought of as an
-.Dq "N to M"
-threading scheme.
-.Pp
-Some general implications of this approach include:
-.Bl -bullet
-.It
-The user process can run multiple threads simultaneously on multi-processor
-machines.
-The kernel grants the process virtual CPUs to schedule as it
-wishes; these may run concurrently on real CPUs.
-.It
-All operations that block in the kernel become asynchronous, allowing
-the user process to schedule another thread when any thread blocks.
-.El
-.\"
-.Ss Definitions
-.\"
-KSE allows a user process to have multiple
-.Sy threads
-of execution in existence at the same time, some of which may be blocked
-in the kernel while others may be executing or blocked in user space.
-A
-.Sy "kernel scheduling entity"
-(KSE) is a
-.Dq "virtual CPU"
-granted to the process for the purpose of executing threads.
-A thread that is currently executing is always associated with
-exactly one KSE, whether executing in user space or in the kernel.
-The KSE is said to be
-.Sy assigned
-to the thread.
-KSEs (a user abstraction) are implemented on top
-of kernel threads using an 'upcall' entity.
-.Pp
-The KSE becomes
-.Sy unassigned ,
-and the associated thread is suspended, when the KSE has an associated
-.Sy mailbox ,
-(see below) the thread has an associated
-.Sy thread mailbox ,
-(also see below) and any of the following occurs:
-.Bl -bullet
-.It
-The thread invokes a system call that blocks.
-.It
-The thread makes any other demand of the kernel that cannot be immediately
-satisfied, e.g., touches a page of memory that needs to be fetched from disk,
-causing a page fault.
-.It
-Another thread that was previously blocked in the kernel completes its
-work in the kernel (or is
-.Sy interrupted )
-and becomes ready to return to user space, and the current thread is returning
-to user space.
-.It
-A signal is delivered to the process, and this KSE is chosen to deliver it.
-.El
-.Pp
-In other words, as soon as there is a scheduling decision to be made,
-the KSE becomes unassigned, because the kernel does not presume to know
-how the process' other runnable threads should be scheduled.
-Unassigned KSEs always return to user space as soon as possible via
-the
-.Sy upcall
-mechanism (described below), allowing the user process to decide how
-that KSE should be utilized next.
-KSEs always complete as much work as possible in the kernel before
-becoming unassigned.
-.Pp
-Individual KSEs within a process are effectively indistinguishable,
-and any KSE in a process may be assigned by the kernel to any runnable
-(in the kernel) thread associated with that process.
-In practice, the kernel attempts to preserve the affinity between threads
-and actual CPUs to optimize cache behavior, but this is invisible to the
-user process.
-(Affinity is not yet fully implemented.)
-.Pp
-Each KSE has a unique
-.Sy "KSE mailbox"
-supplied by the user process.
-A mailbox consists of a control structure containing a pointer to an
-.Sy "upcall function"
-and a user stack.
-The KSE invokes this function whenever it becomes unassigned.
-The kernel updates this structure with information about threads that have
-become runnable and signals that have been delivered before each upcall.
-Upcalls may be temporarily blocked by the user thread scheduling code
-during critical sections.
-.Pp
-Each user thread has a unique
-.Sy "thread mailbox"
-as well.
-Threads are referred to using pointers to these mailboxes when communicating
-between the kernel and the user thread scheduler.
-Each KSE's mailbox contains a pointer to the mailbox of the user thread
-that the KSE is currently executing.
-This pointer is saved when the thread blocks in the kernel.
-.Pp
-Whenever a thread blocked in the kernel is ready to return to user space,
-it is added to the process's list of
-.Sy completed
-threads.
-This list is presented to the user code at the next upcall as a linked list
-of thread mailboxes.
-.Pp
-There is a kernel-imposed limit on the number of threads in a process
-that may be simultaneously blocked in the kernel (this number is not
-currently visible to the user).
-When this limit is reached, upcalls are blocked and no work is performed
-for the process until one of the threads completes (or a signal is
-received).
-.\"
-.Ss Managing KSEs
-.\"
-To become multi-threaded, a process must first invoke
-.Fn kse_create .
-The
-.Fn kse_create
-system call
-creates a new KSE (except for the very first invocation; see below).
-The KSE will be associated with the mailbox pointed to by
-.Fa mbx .
-If
-.Fa sys_scope
-is non-zero, then the new thread will be counted as a system scope
-thread. Other things must be done as well to make a system scope thread
-so this is not sufficient (yet).
-System scope variables are not covered
-in detail in this manual page yet, but briefly, they never perform
-upcalls and do not return to the user thread scheduler.
-Once launched they run autonomously.
-The pthreads library knows how to make system
-scope threads and users are encouraged to use the library interface.
-.Pp
-Each process initially has a single KSE executing a single user thread.
-Since the KSE does not have an associated mailbox, it must remain assigned
-to the thread and does not perform any upcalls.
-(It is by definition a system scope thread).
-The result is the traditional, unthreaded mode of operation.
-Therefore, as a special case, the first call to
-.Fn kse_create
-by this initial thread with
-.Fa sys_scope
-equal to zero does not create a new KSE; instead, it simply associates the
-current KSE with the supplied KSE mailbox, and no immediate upcall results.
-However, an upcall will be triggered the next time the thread blocks and
-the required conditions are met.
-.Pp
-The kernel does not allow more KSEs to exist in a process than the
-number of physical CPUs in the system (this number is available as the
-.Xr sysctl 3
-variable
-.Va hw.ncpu ) .
-Having more KSEs than CPUs would not add any value to the user process,
-as the additional KSEs would just compete with each other for access to
-the real CPUs.
-Since the extra KSEs would always be side-lined, the result
-to the application would be exactly the same as having fewer KSEs.
-There may however be arbitrarily many user threads, and it is up to the
-user thread scheduler to handle mapping the application's user threads
-onto the available KSEs.
-.Pp
-The
-.Fn kse_exit
-system call
-causes the KSE assigned to the currently running thread to be destroyed.
-If this KSE is the last one in the process, there must be no remaining
-threads associated with that process blocked in the kernel.
-This system call does not return unless there is an error.
-Calling
-.Fn kse_exit
-from the last thread is the same as calling
-.Fn exit .
-.Pp
-The
-.Fn kse_release
-system call
-is used to
-.Dq park
-the KSE assigned to the currently running thread when it is not needed,
-e.g., when there are more available KSEs than runnable user threads.
-The thread converts to an upcall but does not get scheduled until
-there is a new reason to do so, e.g., a previously
-blocked thread becomes runnable, or the timeout expires.
-If successful,
-.Fn kse_release
-does not return to the caller.
-.Pp
-The
-.Fn kse_switchin
-system call can be used by the UTS, when it has selected a new thread,
-to switch to the context of that thread.
-The use of
-.Fn kse_switchin
-is machine dependent.
-Some platforms do not need a system call to switch to a new context,
-while others require its use in particular cases.
-.Pp
-The
-.Fn kse_wakeup
-system call
-is the opposite of
-.Fn kse_release .
-It causes the (parked) KSE associated with the mailbox pointed to by
-.Fa mbx
-to be woken up, causing it to upcall.
-If the KSE has already woken up for another reason, this system call has no
-effect.
-The
-.Fa mbx
-argument
-may be
-.Dv NULL
-to specify
-.Dq "any KSE in the current process" .
-.Pp
-The
-.Fn kse_thr_interrupt
-system call
-is used to interrupt a currently blocked thread.
-The thread must either be blocked in the kernel or assigned to a KSE
-(i.e., executing).
-The thread is then marked as interrupted.
-As soon as the thread invokes an interruptible system call (or immediately
-for threads already blocked in one), the thread will be made runnable again,
-even though the kernel operation may not have completed.
-The effect on the interrupted system call is the same as if it had been
-interrupted by a signal; typically this means an error is returned with
-.Va errno
-set to
-.Er EINTR .
-.\"
-.Ss Signals
-.\"
-The current implementation creates a special signal thread.
-Kernel threads (KSEs) in a process mask all signals, and only the signal
-thread waits for signals to be delivered to the process, the signal thread
-is responsible
-for dispatching signals to user threads.
-.Pp
-A downside of this is that if a multiplexed thread
-calls the
-.Fn execve
-syscall, its signal mask and pending signals may not be
-available in the kernel.
-They are stored
-in userland and the kernel does not know where to get them, however
-.Tn POSIX
-requires them to be restored and passed them to new process.
-Just setting the mask for the thread before calling
-.Fn execve
-is only a
-close approximation to the problem as it does not re-deliver back to the kernel
-any pending signals that the old process may have blocked, and it allows a
-window in which new signals may be delivered to the process between the setting
-of the mask and the
-.Fn execve .
-.Pp
-For now this problem has been solved by adding a special combined
-.Fn kse_thr_interrupt Ns / Ns Fn execve
-mode to the
-.Fn kse_thr_interrupt
-syscall.
-The
-.Fn kse_thr_interrupt
-syscall has a sub command
-.Dv KSE_INTR_EXECVE ,
-that allows it to accept a
-.Vt kse_execv_args
-structure, and allowing it to adjust the signals and then atomically
-convert into an
-.Fn execve
-call.
-Additional pending signals and the correct signal mask can be passed
-to the kernel in this way.
-The thread library overrides the
-.Fn execve
-syscall
-and translates it into
-.Fn kse_intr_interrupt
-call, allowing a multiplexed thread
-to restore pending signals and the correct signal mask before doing the
-.Fn exec .
-This solution to the problem may change.
-.\"
-.Ss KSE Mailboxes
-.\"
-Each KSE has a unique mailbox for user-kernel communication defined in
-.In sys/kse.h .
-Some of the fields there are:
-.Pp
-.Va km_version
-describes the version of this structure and must be equal to
-.Dv KSE_VER_0 .
-.Va km_udata
-is an opaque pointer ignored by the kernel.
-.Pp
-.Va km_func
-points to the KSE's upcall function;
-it will be invoked using
-.Va km_stack ,
-which must remain valid for the lifetime of the KSE.
-.Pp
-.Va km_curthread
-always points to the thread that is currently assigned to this KSE if any,
-or
-.Dv NULL
-otherwise.
-This field is modified by both the kernel and the user process as follows.
-.Pp
-When
-.Va km_curthread
-is not
-.Dv NULL ,
-it is assumed to be pointing at the mailbox for the currently executing
-thread, and the KSE may be unassigned, e.g., if the thread blocks in the
-kernel.
-The kernel will then save the contents of
-.Va km_curthread
-with the blocked thread, set
-.Va km_curthread
-to
-.Dv NULL ,
-and upcall to invoke
-.Fn km_func .
-.Pp
-When
-.Va km_curthread
-is
-.Dv NULL ,
-the kernel will never perform any upcalls with this KSE; in other words,
-the KSE remains assigned to the thread even if it blocks.
-.Va km_curthread
-must be
-.Dv NULL
-while the KSE is executing critical user thread scheduler
-code that would be disrupted by an intervening upcall;
-in particular, while
-.Fn km_func
-itself is executing.
-.Pp
-Before invoking
-.Fn km_func
-in any upcall, the kernel always sets
-.Va km_curthread
-to
-.Dv NULL .
-Once the user thread scheduler has chosen a new thread to run,
-it should point
-.Va km_curthread
-at the thread's mailbox, re-enabling upcalls, and then resume the thread.
-.Em Note :
-modification of
-.Va km_curthread
-by the user thread scheduler must be atomic
-with the loading of the context of the new thread, to avoid
-the situation where the thread context area
-may be modified by a blocking async operation, while there
-is still valid information to be read out of it.
-.Pp
-.Va km_completed
-points to a linked list of user threads that have completed their work
-in the kernel since the last upcall.
-The user thread scheduler should put these threads back into its
-own runnable queue.
-Each thread in a process that completes a kernel operation
-(synchronous or asynchronous) that results in an upcall is guaranteed to be
-linked into exactly one KSE's
-.Va km_completed
-list; which KSE in the group, however, is indeterminate.
-Furthermore, the completion will be reported in only one upcall.
-.Pp
-.Va km_sigscaught
-contains the list of signals caught by this process since the previous
-upcall to any KSE in the process.
-As long as there exists one or more KSEs with an associated mailbox in
-the user process, signals are delivered this way rather than the
-traditional way.
-(This has not been implemented and may change.)
-.Pp
-.Va km_timeofday
-is set by the kernel to the current system time before performing
-each upcall.
-.Pp
-.Va km_flags
-may contain any of the following bits OR'ed together:
-.Bl -tag -width indent
-.It Dv KMF_NOUPCALL
-Block upcalls from happening.
-The thread is in some critical section.
-.It Dv KMF_NOCOMPLETED , KMF_DONE , KMF_BOUND
-This thread should be considered to be permanently bound to
-its KSE, and treated much like a non-threaded process would be.
-It is a
-.Dq "long term"
-version of
-.Dv KMF_NOUPCALL
-in some ways.
-.It Dv KMF_WAITSIGEVENT
-Implement characteristics needed for the signal delivery thread.
-.El
-.\"
-.Ss Thread Mailboxes
-.\"
-Each user thread must have associated with it a unique
-.Vt "struct kse_thr_mailbox"
-as defined in
-.In sys/kse.h .
-It includes the following fields.
-.Pp
-.Va tm_udata
-is an opaque pointer ignored by the kernel.
-.Pp
-.Va tm_context
-stores the context for the thread when the thread is blocked in user space.
-This field is also updated by the kernel before a completed thread is returned
-to the user thread scheduler via
-.Va km_completed .
-.Pp
-.Va tm_next
-links the
-.Va km_completed
-threads together when returned by the kernel with an upcall.
-The end of the list is marked with a
-.Dv NULL
-pointer.
-.Pp
-.Va tm_uticks
-and
-.Va tm_sticks
-are time counters for user mode and kernel mode execution, respectively.
-These counters count ticks of the statistics clock (see
-.Xr clocks 7 ) .
-While any thread is actively executing in the kernel, the corresponding
-.Va tm_sticks
-counter is incremented.
-While any KSE is executing in user space and that KSE's
-.Va km_curthread
-pointer is not equal to
-.Dv NULL ,
-the corresponding
-.Va tm_uticks
-counter is incremented.
-.Pp
-.Va tm_flags
-may contain any of the following bits OR'ed together:
-.Bl -tag -width indent
-.It Dv TMF_NOUPCALL
-Similar to
-.Dv KMF_NOUPCALL .
-This flag inhibits upcalling for critical sections.
-Some architectures require this to be in one place and some in the other.

-.Sh SYNOPSIS
-.In sys/param.h
-.In sys/time.h
-.In sys/uio.h
-.In sys/ktrace.h
-.Ft int
-.Fn ktrace "const char *tracefile" "int ops" "int trpoints" "int pid"
-.Sh DESCRIPTION
-The
-.Fn ktrace
-system call enables or disables tracing of one or more processes.
-Users may only trace their own processes.
-Only the super-user can trace setuid or setgid programs.
-.Pp
-The
-.Fa tracefile
-argument
-gives the pathname of the file to be used for tracing.
-The file must exist and be a regular file writable by the calling process.
-All trace records are always appended to the file,
-so the file must be truncated to zero length to discard
-previous trace data.
-If tracing points are being disabled (see KTROP_CLEAR below),
-.Fa tracefile
-may be NULL.
-.Pp
-The
-.Fa ops
-argument specifies the requested ktrace operation.
-The defined operations are:
-.Bl -column KTRFLAG_DESCENDXXX -offset indent
-.It "KTROP_SET Enable trace points specified in"
-.Fa trpoints .
-.It "KTROP_CLEAR Disable trace points specified in
-.Fa trpoints .
-.It "KTROP_CLEARFILE Stop all tracing."
-.It "KTRFLAG_DESCEND The tracing change should apply to the"
-specified process and all its current children.
-.El
-.Pp
-The
-.Fa trpoints
-argument specifies the trace points of interest.
-The defined trace points are:
-.Bl -column KTRFAC_SYSCALLXXX -offset indent
-.It "KTRFAC_SYSCALL Trace system calls."
-.It "KTRFAC_SYSRET Trace return values from system calls."
-.It "KTRFAC_NAMEI Trace name lookup operations."
-.It "KTRFAC_GENIO Trace all I/O (note that this option can"
-generate much output).
-.It "KTRFAC_PSIG Trace posted signals."
-.It "KTRFAC_CSW Trace context switch points."
-.It "KTRFAC_INHERIT Inherit tracing to future children."
-.El
-.Pp
-Each tracing event outputs a record composed of a generic header
-followed by a trace point specific structure.
-The generic header is:
-.Bd -literal
-struct ktr_header {
- int ktr_len; /* length of buf */
- short ktr_type; /* trace record type */
- pid_t ktr_pid; /* process id */
- char ktr_comm[MAXCOMLEN+1]; /* command name */
- struct timeval ktr_time; /* timestamp */
- intptr_t ktr_tid; /* was ktr_buffer */
-};
-.Ed
-.Pp
-The
-.Va ktr_len
-field specifies the length of the
-.Va ktr_type
-data that follows this header.
-The
-.Va ktr_pid
-and
-.Va ktr_comm
-fields specify the process and command generating the record.
-The
-.Va ktr_time
-field gives the time (with microsecond resolution)
-that the record was generated.
-The
-.Va ktr_tid
-field holds a threadid.
-.Pp
-The generic header is followed by
-.Va ktr_len
-bytes of a
-.Va ktr_type
-record.
-The type specific records are defined in the
-.In sys/ktrace.h
-include file.
-.Sh SYSCTL TUNABLES
-The following
-.Xr sysctl 8
-tunables influence the behaviour of
-.Fn ktrace :
-.Bl -tag -width indent
-.It Va kern.ktrace.geniosize
-bounds the amount of data a traced I/O request will log
-to the trace file.
-.It Va kern.ktrace.request_pool
-bounds the number of trace events being logged at a time.
-.El
-.Pp
-Sysctl tunables that control process debuggability (as determined by
-.Xr p_candebug 9 )
-also affect the operation of
-.Fn ktrace .
-.Sh RETURN VALUES
-.Rv -std ktrace
-.Sh ERRORS
-The
-.Fn ktrace
-system call
-will fail if:
-.Bl -tag -width Er
-.It Bq Er ENOTDIR
-A component of the path prefix is not a directory.
-.It Bq Er ENAMETOOLONG

-.It Bq Er ENOENT
-The named tracefile does not exist.
-.It Bq Er EACCES
-Search permission is denied for a component of the path prefix.
-.It Bq Er ELOOP
-Too many symbolic links were encountered in translating the pathname.
-.It Bq Er EIO
-An I/O error occurred while reading from or writing to the file system.
-.It Bq Er ENOSYS
-The kernel was not compiled with
-.Nm
-support.
-.El
-.Pp
-A thread may be unable to log one or more tracing events due to a
-temporary shortage of resources.
-This condition is remembered by the kernel, and the next tracing request
-that succeeds will have the flag
-.Li KTR_DROP
-set in its
-.Va ktr_type
-field.

-.Sh DESCRIPTION
-The
-.Fn link
-system call
-atomically creates the specified directory entry (hard link)
-.Fa name2
-with the attributes of the underlying object pointed at by
-.Fa name1 .
-If the link is successful: the link count of the underlying object
-is incremented;
-.Fa name1
-and
-.Fa name2
-share equal access and rights
-to the
-underlying object.
-.Pp
-If
-.Fa name1
-is removed, the file
-.Fa name2
-is not deleted and the link count of the
-underlying object is
-decremented.
-.Pp
-The object pointed at by the
-.Fa name1
-argument
-must exist for the hard link to
-succeed and
-both
-.Fa name1
-and
-.Fa name2
-must be in the same file system.
-The
-.Fa name1
-argument
-may not be a directory.
-.Pp
-The
-.Fn linkat
-system call is equivalent to
-.Fa link
-except in the case where either
-.Fa name1
-or
-.Fa name2
-or both are relative paths.
-In this case a relative path
-.Fa name1
-is interpreted relative to
-the directory associated with the file descriptor
-.Fa fd1
-instead of the current working directory and similarly for
-.Fa name2
-and the file descriptor
-.Fa fd2 .
-.Pp
-Values for
-.Fa flag
-are constructed by a bitwise-inclusive OR of flags from the following
-list, defined in
-.In fcntl.h :
-.Bl -tag -width indent
-.It Dv AT_SYMLINK_FOLLOW
-If
-.Fa name1
-names a symbolic link, a new link for the target of the symbolic link is

-.Pp
-If
-.Fn linkat
-is passed the special value
-.Dv AT_FDCWD
-in the
-.Fa fd1
-or

-parameter, the current working directory is used for the respective
-.Fa name
-argument.
-If both
-.Fa fd1
-and
-.Fa fd2
-have value
-.Dv AT_FDCWD ,
-the behavior is identical to a call to
-.Fn link .
-Unless
-.Fa flag
-contains the
-.Dv AT_SYMLINK_FOLLOW
-flag, if
-.Fa name1
-names a symbolic link, a new link is created for the symbolic link
-.Fa name1
-and not its target.

-.Dt LISTEN 2
-.Os
-.Sh NAME
-.Nm listen
-.Nd listen for connections on a socket
-.Sh LIBRARY
-.Lb libc
-.Sh SYNOPSIS
-.In sys/types.h
-.In sys/socket.h
-.Ft int
-.Fn listen "int s" "int backlog"
-.Sh DESCRIPTION
-To accept connections, a socket
-is first created with
-.Xr socket 2 ,
-a willingness to accept incoming connections and
-a queue limit for incoming connections are specified with
-.Fn listen ,
-and then the connections are
-accepted with
-.Xr accept 2 .
-The
-.Fn listen
-system call applies only to sockets of type
-.Dv SOCK_STREAM
-or
-.Dv SOCK_SEQPACKET .
-.Pp
-The
-.Fa backlog
-argument defines the maximum length the queue of
-pending connections may grow to.
-The real maximum queue length will be 1.5 times more than the value
-specified in the
-.Fa backlog
-argument.
-A subsequent
-.Fn listen
-system call on the listening socket allows the caller to change the maximum
-queue length using a new
-.Fa backlog
-argument.
-If a connection
-request arrives with the queue full the client may
-receive an error with an indication of
-.Er ECONNREFUSED ,
-or, in the case of TCP, the connection will be
-silently dropped.
-.Pp
-Current queue lengths of listening sockets can be queried using
-.Xr netstat 1
-command.
-.Pp
-Note that before
-.Fx 4.5
-and the introduction of the syncache,
-the
-.Fa backlog
-argument also determined the length of the incomplete
-connection queue, which held TCP sockets in the process
-of completing TCP's 3-way handshake.
-These incomplete connections
-are now held entirely in the syncache, which is unaffected by
-queue lengths.
-Inflated
-.Fa backlog
-values to help handle denial
-of service attacks are no longer necessary.
-.Pp
-The
-.Xr sysctl 3
-MIB variable
-.Va kern.ipc.somaxconn
-specifies a hard limit on
-.Fa backlog ;
-if a value greater than
-.Va kern.ipc.somaxconn
-or less than zero is specified,
-.Fa backlog
-is silently forced to
-.Va kern.ipc.somaxconn .
-.Sh INTERACTION WITH ACCEPT FILTERS
-When accept filtering is used on a socket, a second queue will
-be used to hold sockets that have connected, but have not yet
-met their accept filtering criteria.
-Once the criteria has been
-met, these sockets will be moved over into the completed connection
-queue to be
-.Xr accept 2 Ns ed .
-If this secondary queue is full and a
-new connection comes in, the oldest socket which has not yet met
-its accept filter criteria will be terminated.
-.Pp
-This secondary queue, like the primary listen queue, is sized
-according to the
-.Fa backlog
-argument.
-.Sh RETURN VALUES
-.Rv -std listen
-.Sh ERRORS
-The
-.Fn listen
-system call
-will fail if:
-.Bl -tag -width Er
-.It Bq Er EBADF
-The argument
-.Fa s
-is not a valid descriptor.
-.It Bq Er EINVAL
-The socket is already connected, or in the process of being connected.
-.It Bq Er ENOTSOCK
-The argument
-.Fa s
-is not a socket.
-.It Bq Er EOPNOTSUPP
-The socket is not of a type that supports the operation
-.Fn listen .

-.Sh HISTORY
-The
-.Fn listen
-system call appeared in
-.Bx 4.2 .
-The ability to configure the maximum
-.Fa backlog
-at run-time, and to use a negative
-.Fa backlog
-to request the maximum allowable value, was introduced in
-.Fx 2.2 .

-.Sh LIBRARY
-.Lb libc
-.Sh SYNOPSIS
-.In unistd.h
-.Ft off_t
-.Fn lseek "int fildes" "off_t offset" "int whence"
-.Sh DESCRIPTION
-The
-.Fn lseek
-system call repositions the offset of the file descriptor
-.Fa fildes
-to the
-argument
-.Fa offset
-according to the directive
-.Fa whence .
-The argument
-.Fa fildes
-must be an open
-file descriptor.
-The
-.Fn lseek
-system call
-repositions the file position pointer associated with the file
-descriptor
-.Fa fildes
-as follows:
-.Bl -item -offset indent
-.It
-If
-.Fa whence
-is
-.Dv SEEK_SET ,
-the offset is set to
-.Fa offset
-bytes.
-.It
-If
-.Fa whence
-is
-.Dv SEEK_CUR ,
-the offset is set to its current location plus
-.Fa offset
-bytes.
-.It
-If
-.Fa whence
-is
-.Dv SEEK_END ,
-the offset is set to the size of the
-file plus
-.Fa offset
-bytes.
-.It
-If
-.Fa whence
-is
-.Dv SEEK_HOLE ,
-the offset of the start of the next hole greater than or equal to the supplied
-.Fa offset
-is returned.
-The definition of a hole is provided below.
-.It
-If
-.Fa whence
-is
-.Dv SEEK_DATA ,
-the offset is set to the start of the next non-hole file region greater
-than or equal to the supplied
-.Fa offset .
-.El
-.Pp
-The
-.Fn lseek
-system call allows the file offset to be set beyond the end
-of the existing end-of-file of the file.
-If data is later written
-at this point, subsequent reads of the data in the gap return
-bytes of zeros (until data is actually written into the gap).
-.Pp
-Some devices are incapable of seeking.
-The value of the pointer
-associated with such a device is undefined.
-.Pp
-A
-.Qq hole
-is defined as a contiguous range of bytes in a file, all having the value of
-zero, but not all zeros in a file are guaranteed to be represented as holes
-returned with
-.Dv SEEK_HOLE .
-File systems are allowed to expose ranges of zeros with
-.Dv SEEK_HOLE ,
-but not required to.
-Applications can use
-.Dv SEEK_HOLE
-to optimise their behavior for ranges of zeros, but must not depend on it to
-find all such ranges in a file.
-The existence of a hole at the end of every data region allows for easy
-programming and implies that a virtual hole exists at the end of the file.
-Applications should use
-.Fn fpathconf _PC_MIN_HOLE_SIZE
-or
-.Fn pathconf _PC_MIN_HOLE_SIZE
-to determine if a file system supports
-.Dv SEEK_HOLE .
-See
-.Xr pathconf 2 .
-.Pp
-For file systems that do not supply information about holes, the file will be
-represented as one entire data region.
-.Sh RETURN VALUES
-Upon successful completion,
-.Fn lseek
-returns the resulting offset location as measured in bytes from the
-beginning of the file.
-Otherwise,
-a value of -1 is returned and
-.Va errno
-is set to indicate
-the error.
-.Sh ERRORS
-The
-.Fn lseek
-system call
-will fail and the file position pointer will remain unchanged if:
-.Bl -tag -width Er
-.It Bq Er EBADF
-The
-.Fa fildes
-argument
-is not an open file descriptor.
-.It Bq Er EINVAL
-The
-.Fa whence
-argument
-is not a proper value
-or the resulting file offset would
-be negative for a non-character special file.
-.It Bq Er ENXIO
-For
-.Dv SEEK_DATA ,
-there are no more data regions past the supplied offset.
-For
-.Dv SEEK_HOLE ,
-there are no more holes past the supplied offset.
-.It Bq Er EOVERFLOW
-The resulting file offset would be a value which cannot be represented
-correctly in an object of type
-.Fa off_t .
-.It Bq Er ESPIPE
-The
-.Fa fildes
-argument
-is associated with a pipe, socket, or FIFO.
-.El
-.Sh SEE ALSO
-.Xr dup 2 ,
-.Xr open 2 ,

-.Ft int
-.Fn madvise "void *addr" "size_t len" "int behav"
-.Ft int
-.Fn posix_madvise "void *addr" "size_t len" "int behav"
-.Sh DESCRIPTION
-The
-.Fn madvise
-system call
-allows a process that has knowledge of its memory behavior
-to describe it to the system.
-The
-.Fn posix_madvise
-interface is identical and is provided for standards conformance.
-.Pp
-The known behaviors are:
-.Bl -tag -width MADV_SEQUENTIAL
-.It Dv MADV_NORMAL
-Tells the system to revert to the default paging
-behavior.
-.It Dv MADV_RANDOM
-Is a hint that pages will be accessed randomly, and prefetching
-is likely not advantageous.
-.It Dv MADV_SEQUENTIAL
-Causes the VM system to depress the priority of
-pages immediately preceding a given page when it is faulted in.
-.It Dv MADV_WILLNEED
-Causes pages that are in a given virtual address range
-to temporarily have higher priority, and if they are in
-memory, decrease the likelihood of them being freed.
-Additionally,
-the pages that are already in memory will be immediately mapped into
-the process, thereby eliminating unnecessary overhead of going through
-the entire process of faulting the pages in.
-This WILL NOT fault
-pages in from backing store, but quickly map the pages already in memory
-into the calling process.
-.It Dv MADV_DONTNEED
-Allows the VM system to decrease the in-memory priority
-of pages in the specified range.
-Additionally future references to
-this address range will incur a page fault.
-.It Dv MADV_FREE
-Gives the VM system the freedom to free pages,
-and tells the system that information in the specified page range
-is no longer important.
-This is an efficient way of allowing
-.Xr malloc 3
-to free pages anywhere in the address space, while keeping the address space
-valid.
-The next time that the page is referenced, the page might be demand
-zeroed, or might contain the data that was there before the
-.Dv MADV_FREE
-call.
-References made to that address space range will not make the VM system
-page the information back in from backing store until the page is
-modified again.
-.It Dv MADV_NOSYNC
-Request that the system not flush the data associated with this map to
-physical backing store unless it needs to.
-Typically this prevents the
-file system update daemon from gratuitously writing pages dirtied
-by the VM system to physical disk.
-Note that VM/file system coherency is
-always maintained, this feature simply ensures that the mapped data is
-only flush when it needs to be, usually by the system pager.
-.Pp
-This feature is typically used when you want to use a file-backed shared
-memory area to communicate between processes (IPC) and do not particularly
-need the data being stored in that area to be physically written to disk.
-With this feature you get the equivalent performance with mmap that you
-would expect to get with SysV shared memory calls, but in a more controllable
-and less restrictive manner.
-However, note that this feature is not portable
-across UNIX platforms (though some may do the right thing by default).
-For more information see the MAP_NOSYNC section of
-.Xr mmap 2
-.It Dv MADV_AUTOSYNC
-Undoes the effects of MADV_NOSYNC for any future pages dirtied within the
-address range.
-The effect on pages already dirtied is indeterminate - they
-may or may not be reverted.
-You can guarantee reversion by using the
-.Xr msync 2
-or
-.Xr fsync 2
-system calls.
-.It Dv MADV_NOCORE
-Region is not included in a core file.
-.It Dv MADV_CORE
-Include region in a core file.
-.It Dv MADV_PROTECT
-Informs the VM system this process should not be killed when the
-swap space is exhausted.
-The process must have superuser privileges.
-This should be used judiciously in processes that must remain running
-for the system to properly function.
-.El
-.Pp
-Portable programs that call the
-.Fn posix_madvise
-interface should use the aliases
-.Dv POSIX_MADV_NORMAL , POSIX_MADV_SEQUENTIAL ,

-.Sh LIBRARY
-.Lb libc
-.Sh SYNOPSIS
-.In sys/mman.h
-.Ft int
-.Fn minherit "void *addr" "size_t len" "int inherit"
-.Sh DESCRIPTION
-The
-.Fn minherit
-system call
-changes the specified pages to have the inheritance characteristic
-.Fa inherit .
-Not all implementations will guarantee that the inheritance characteristic
-can be set on a page basis;
-the granularity of changes may be as large as an entire region.
-.Fx
-is capable of adjusting inheritance characteristics on a page basis.
-Inheritance only effects children created by
-.Fn fork .
-It has no effect on
-.Fn exec .
-exec'd processes replace their address space entirely.
-This system call also
-has no effect on the parent's address space (other than to potentially
-share the address space with its children).
-.Pp
-Inheritance is a rather esoteric feature largely superseded by the
-.Dv MAP_SHARED
-feature of
-.Fn mmap .
-However, it is possible to use
-.Fn minherit
-to share a block of memory between parent and child that has been mapped
-.Dv MAP_PRIVATE .
-That is, modifications made by parent or child are shared but
-the original underlying file is left untouched.
-.Bl -tag -width ".Dv INHERIT_SHARE"
-.It Dv INHERIT_SHARE
-This option causes the address space in question to be shared between
-parent and child.
-It has no effect on how the original underlying backing
-store was mapped.
-.It Dv INHERIT_NONE
-This option prevents the address space in question from being inherited
-at all.
-The address space will be unmapped in the child.
-.It Dv INHERIT_COPY
-This option causes the child to inherit the address space as copy-on-write.
-This option also has an unfortunate side effect of causing the parent
-address space to become copy-on-write when the parent forks.
-If the original mapping was
-.Dv MAP_SHARED ,
-it will no longer be shared in the parent
-after the parent forks and there is no way to get the previous
-shared-backing-store mapping without unmapping and remapping the address
-space in the parent.
-.El
-.Sh RETURN VALUES
-.Rv -std minherit
-.Sh ERRORS
-The
-.Fn minherit
-system call will fail if:
-.Bl -tag -width Er
-.It Bq Er EINVAL
-The virtual address range specified by the
-.Fa addr
-and
-.Fa len
-arguments is not valid.
-.It Bq Er EACCES
-The flags specified by the

-The

-and then in

-.Sh BUGS
-Once you set inheritance to
-.Dv MAP_PRIVATE
-or
-.Dv MAP_SHARED ,
-there is no way to recover the original copy-on-write semantics
-short of unmapping and remapping the area.

-.Ft int
-.Fn munlockall "void"
-.Sh DESCRIPTION
-The
-.Fn mlockall
-system call locks into memory the physical pages associated with the
-address space of a process until the address space is unlocked, the
-process exits, or execs another program image.
-.Pp
-The following flags affect the behavior of
-.Fn mlockall :
-.Bl -tag -width ".Dv MCL_CURRENT"
-.It Dv MCL_CURRENT
-Lock all pages currently mapped into the process's address space.
-.It Dv MCL_FUTURE
-Lock all pages mapped into the process's address space in the future,
-at the time the mapping is established.
-Note that this may cause future mappings to fail if those mappings
-cause resource limits to be exceeded.
-.El
-.Pp
-Since physical memory is a potentially scarce resource, processes are
-limited in how much they can lock down.
-A single process can lock the minimum of a system-wide
-.Dq wired pages
-limit and the per-process
-.Dv RLIMIT_MEMLOCK
-resource limit.
-.Pp
-These calls are only available to the super-user.
-.Pp
-The
-.Fn munlockall
-call unlocks any locked memory regions in the process address space.
-Any regions mapped after an
-.Fn munlockall
-call will not be locked.
-.Sh RETURN VALUES
-A return value of 0 indicates that the call
-succeeded and all pages in the range have either been locked or unlocked.
-A return value of \-1 indicates an error occurred and the locked
-status of all pages in the range remains unchanged.
-In this case, the global location
-.Va errno
-is set to indicate the error.
-.Sh ERRORS
-.Fn mlockall
-will fail if:
-.Bl -tag -width Er
-.It Bq Er EINVAL
-The
-.Fa flags
-argument is zero, or includes unimplemented flags.
-.It Bq Er ENOMEM
-Locking the indicated range would exceed either the system or per-process
-limit for locked memory.
-.It Bq Er EAGAIN
-Some or all of the memory mapped into the process's address space
-could not be locked when the call was made.
-.It Bq Er EPERM
-The calling process does not have the appropriate privilege to perform
-the requested operation.

-.Dt MMAP 2
-.Os
-.Sh NAME
-.Nm mmap
-.Nd allocate memory, or map files or devices into memory
-.Sh LIBRARY
-.Lb libc
-.Sh SYNOPSIS
-.In sys/mman.h
-.Ft void *
-.Fn mmap "void *addr" "size_t len" "int prot" "int flags" "int fd" "off_t offset"
-.Sh DESCRIPTION
-The
-.Fn mmap
-system call causes the pages starting at
-.Fa addr
-and continuing for at most
-.Fa len
-bytes to be mapped from the object described by
-.Fa fd ,
-starting at byte offset
-.Fa offset .
-If
-.Fa len
-is not a multiple of the pagesize, the mapped region may extend past the
-specified range.
-Any such extension beyond the end of the mapped object will be zero-filled.
-.Pp
-If
-.Fa addr
-is non-zero, it is used as a hint to the system.
-(As a convenience to the system, the actual address of the region may differ
-from the address supplied.)
-If
-.Fa addr
-is zero, an address will be selected by the system.
-The actual starting address of the region is returned.
-A successful
-.Fa mmap
-deletes any previous mapping in the allocated address range.
-.Pp
-The protections (region accessibility) are specified in the
-.Fa prot
-argument by
-.Em or Ns 'ing
-the following values:
-.Pp
-.Bl -tag -width PROT_WRITE -compact
-.It Dv PROT_NONE
-Pages may not be accessed.
-.It Dv PROT_READ
-Pages may be read.
-.It Dv PROT_WRITE
-Pages may be written.
-.It Dv PROT_EXEC
-Pages may be executed.
-.El
-.Pp
-The
-.Fa flags
-argument specifies the type of the mapped object, mapping options and
-whether modifications made to the mapped copy of the page are private
-to the process or are to be shared with other references.
-Sharing, mapping type and options are specified in the
-.Fa flags
-argument by
-.Em or Ns 'ing
-the following values:
-.Bl -tag -width MAP_HASSEMAPHORE
-.It Dv MAP_ANON
-Map anonymous memory not associated with any specific file.
-The file descriptor used for creating
-.Dv MAP_ANON
-must be \-1.
-The
-.Fa offset
-argument must be 0.
-.\".It Dv MAP_FILE
-.\"Mapped from a regular file or character-special device memory.
-.It Dv MAP_ANONYMOUS
-This flag is identical to
-.Dv MAP_ANON
-and is provided for compatibility.
-.It Dv MAP_FIXED
-Do not permit the system to select a different address than the one
-specified.
-If the specified address cannot be used,
-.Fn mmap
-will fail.
-If
-.Dv MAP_FIXED
-is specified,
-.Fa addr
-must be a multiple of the pagesize.
-If a
-.Dv MAP_FIXED
-request is successful, the mapping established by
-.Fn mmap
-replaces any previous mappings for the process' pages in the range from
-.Fa addr
-to
-.Fa addr
-+
-.Fa len .
-Use of this option is discouraged.
-.It Dv MAP_HASSEMAPHORE
-Notify the kernel that the region may contain semaphores and that special
-handling may be necessary.
-.It Dv MAP_INHERIT
-This flag never operated as advertised and is no longer supported.
-Please refer to
-.Xr minherit 2
-for further information.
-.It Dv MAP_NOCORE
-Region is not included in a core file.
-.It Dv MAP_NOSYNC
-Causes data dirtied via this VM map to be flushed to physical media
-only when necessary (usually by the pager) rather than gratuitously.
-Typically this prevents the update daemons from flushing pages dirtied
-through such maps and thus allows efficient sharing of memory across
-unassociated processes using a file-backed shared memory map.
-Without
-this option any VM pages you dirty may be flushed to disk every so often
-(every 30-60 seconds usually) which can create performance problems if you
-do not need that to occur (such as when you are using shared file-backed
-mmap regions for IPC purposes).
-Note that VM/file system coherency is
-maintained whether you use
-.Dv MAP_NOSYNC
-or not.
-This option is not portable
-across
-.Ux
-platforms (yet), though some may implement the same behavior
-by default.
-.Pp
-.Em WARNING !
-Extending a file with
-.Xr ftruncate 2 ,
-thus creating a big hole, and then filling the hole by modifying a shared
-.Fn mmap
-can lead to severe file fragmentation.
-In order to avoid such fragmentation you should always pre-allocate the
-file's backing store by
-.Fn write Ns ing
-zero's into the newly extended area prior to modifying the area via your
-.Fn mmap .
-The fragmentation problem is especially sensitive to
-.Dv MAP_NOSYNC
-pages, because pages may be flushed to disk in a totally random order.
-.Pp
-The same applies when using
-.Dv MAP_NOSYNC
-to implement a file-based shared memory store.
-It is recommended that you create the backing store by
-.Fn write Ns ing
-zero's to the backing file rather than
-.Fn ftruncate Ns ing
-it.
-You can test file fragmentation by observing the KB/t (kilobytes per
-transfer) results from an
-.Dq Li iostat 1
-while reading a large file sequentially, e.g.\& using
-.Dq Li dd if=filename of=/dev/null bs=32k .
-.Pp
-The
-.Xr fsync 2
-system call will flush all dirty data and metadata associated with a file,
-including dirty NOSYNC VM data, to physical media.
-The
-.Xr sync 8
-command and
-.Xr sync 2
-system call generally do not flush dirty NOSYNC VM data.
-The
-.Xr msync 2
-system call is obsolete since
-.Bx
-implements a coherent file system buffer cache.
-However, it may be
-used to associate dirty VM pages with file system buffers and thus cause
-them to be flushed to physical media sooner rather than later.
-.It Dv MAP_PREFAULT_READ
-Immediately update the calling process's lowest-level virtual address
-translation structures, such as its page table, so that every memory
-resident page within the region is mapped for read access.
-Ordinarily these structures are updated lazily.
-The effect of this option is to eliminate any soft faults that would
-otherwise occur on the initial read accesses to the region.
-Although this option does not preclude
-.Fa prot
-from including
-.Dv PROT_WRITE ,
-it does not eliminate soft faults on the initial write accesses to the
-region.
-.It Dv MAP_PRIVATE
-Modifications are private.
-.It Dv MAP_SHARED
-Modifications are shared.
-.It Dv MAP_STACK
-.Dv MAP_STACK
-implies
-.Dv MAP_ANON ,
-and
-.Fa offset
-of 0.
-The
-.Fa fd
-argument
-must be -1 and
-.Fa prot
-must include at least
-.Dv PROT_READ
-and
-.Dv PROT_WRITE .
-This option creates
-a memory region that grows to at most
-.Fa len
-bytes in size, starting from the stack top and growing down.
-The
-stack top is the starting address returned by the call, plus
-.Fa len
-bytes.
-The bottom of the stack at maximum growth is the starting
-address returned by the call.
-.El
-.Pp
-The
-.Xr close 2
-system call does not unmap pages, see
-.Xr munmap 2
-for further information.
-.Pp
-The current design does not allow a process to specify the location of
-swap space.
-In the future we may define an additional mapping type,
-.Dv MAP_SWAP ,
-in which
-the file descriptor argument specifies a file or device to which swapping
-should be done.
-.Sh NOTES
-Although this implementation does not impose any alignment restrictions on
-the
-.Fa offset
-argument, a portable program must only use page-aligned values.
-.Sh RETURN VALUES
-Upon successful completion,
-.Fn mmap
-returns a pointer to the mapped region.
-Otherwise, a value of
-.Dv MAP_FAILED
-is returned and
-.Va errno
-is set to indicate the error.
-.Sh ERRORS
-The
-.Fn mmap
-system call
-will fail if:

-Files may not be able to be made more than 1TB large on 32 bit systems
-due to file systems restrictions and bugs, but address space is far more

-.Dt MOUNT 2
-.Os
-.Sh NAME
-.Nm mount ,
-.Nm nmount ,
-.Nm unmount
-.Nd mount or dismount a file system
-.Sh LIBRARY
-.Lb libc
-.Sh SYNOPSIS
-.In sys/param.h
-.In sys/mount.h
-.Ft int
-.Fn mount "const char *type" "const char *dir" "int flags" "void *data"
-.Ft int
-.Fn unmount "const char *dir" "int flags"
-.In sys/uio.h
-.Ft int
-.Fn nmount "struct iovec *iov" "u_int niov" "int flags"
-.Sh DESCRIPTION
-The
-.Fn mount
-system call grafts
-a file system object onto the system file tree
-at the point
-.Fa dir .
-The argument
-.Fa data
-describes the file system object to be mounted.
-The argument
-.Fa type
-tells the kernel how to interpret
-.Fa data
-(See
-.Fa type
-below).
-The contents of the file system
-become available through the new mount point
-.Fa dir .
-Any files in
-.Fa dir
-at the time
-of a successful mount are swept under the carpet so to speak, and
-are unavailable until the file system is unmounted.
-.Pp
-The
-.Fn nmount
-system call behaves similarly to
-.Fn mount ,
-except that the mount options (file system type name, device to mount,
-mount-point name, etc.) are passed as an array of name-value pairs
-in the array
-.Fa iov ,
-containing
-.Fa niov
-elements.
-The following options are required by all file systems:
-.Bl -item -offset indent -compact
-.It
-.Li fstype Ta file system type name (e.g., Dq Li procfs )
-.It
-.Li fspath Ta mount point pathname (e.g., Dq Li /proc )
-.El
-.Pp
-Depending on the file system type, other options may be
-recognized or required;
-for example, most disk-based file systems require a
-.Dq Li from
-option containing the pathname of a special device
-in addition to the options listed above.
-.Pp
-By default only the super-user may call the
-.Fn mount
-system call.
-This restriction can be removed by setting the
-.Va vfs.usermount
-.Xr sysctl 8
-variable
-to a non-zero value; see the BUGS section for more information.
-.Pp
-The following
-.Fa flags
-may be specified to
-suppress default semantics which affect file system access.
-.Bl -tag -width MNT_SYNCHRONOUS
-.It Dv MNT_RDONLY
-The file system should be treated as read-only;
-even the super-user may not write on it.
-Specifying MNT_UPDATE without this option will upgrade
-a read-only file system to read/write.
-.It Dv MNT_NOEXEC
-Do not allow files to be executed from the file system.
-.It Dv MNT_NOSUID
-Do not honor setuid or setgid bits on files when executing them.
-This flag is set automatically when the caller is not the super-user.
-.It Dv MNT_NOATIME
-Disable update of file access times.
-.It Dv MNT_SNAPSHOT
-Create a snapshot of the file system.
-This is currently only supported on UFS2 file systems, see
-.Xr mksnap_ffs 8
-for more information.
-.It Dv MNT_SUIDDIR
-Directories with the SUID bit set chown new files to their own owner.
-This flag requires the SUIDDIR option to have been compiled into the kernel
-to have any effect.
-See the
-.Xr mount 8
-and
-.Xr chmod 2
-pages for more information.
-.It Dv MNT_SYNCHRONOUS
-All I/O to the file system should be done synchronously.
-.It Dv MNT_ASYNC
-All I/O to the file system should be done asynchronously.
-.It Dv MNT_FORCE
-Force a read-write mount even if the file system appears to be unclean.
-Dangerous.
-Together with
-.Dv MNT_UPDATE
-and
-.Dv MNT_RDONLY ,
-specify that the file system is to be forcibly downgraded to a read-only
-mount even if some files are open for writing.
-.It Dv MNT_NOCLUSTERR
-Disable read clustering.
-.It Dv MNT_NOCLUSTERW
-Disable write clustering.
-.El
-.Pp
-The flag
-.Dv MNT_UPDATE
-indicates that the mount command is being applied
-to an already mounted file system.
-This allows the mount flags to be changed without requiring
-that the file system be unmounted and remounted.
-Some file systems may not allow all flags to be changed.
-For example,
-many file systems will not allow a change from read-write to read-only.
-.Pp
-The flag
-.Dv MNT_RELOAD
-causes the vfs subsystem to update its data structures pertaining to
-the specified already mounted file system.
-.Pp
-The
-.Fa type
-argument names the file system.
-The types of file systems known to the system can be obtained with
-.Xr lsvfs 1 .
-.Pp
-The
-.Fa data
-argument
-is a pointer to a structure that contains the type
-specific arguments to mount.
-The format for these argument structures is described in the
-manual page for each file system.
-By convention file system manual pages are named
-by prefixing ``mount_'' to the name of the file system as returned by
-.Xr lsvfs 1 .
-Thus the
-.Tn NFS
-file system is described by the
-.Xr mount_nfs 8
-manual page.
-It should be noted that a manual page for default
-file systems, known as UFS and UFS2, does not exist.
-.Pp
-The
-.Fn unmount
-system call disassociates the file system from the specified
-mount point
-.Fa dir .
-.Pp
-The
-.Fa flags
-argument may include
-.Dv MNT_FORCE
-to specify that the file system should be forcibly unmounted
-even if files are still active.
-Active special devices continue to work,
-but any further accesses to any other active files result in errors
-even if the file system is later remounted.
-.Pp
-If the
-.Dv MNT_BYFSID
-flag is specified,
-.Fa dir
-should instead be a file system ID encoded as
-.Dq Li FSID : Ns Ar val0 : Ns Ar val1 ,
-where
-.Ar val0
-and
-.Ar val1
-are the contents of the
-.Vt fsid_t
-.Va val[]
-array in decimal.
-The file system that has the specified file system ID will be unmounted.
-.Sh RETURN VALUES
-.Rv -std
-.Sh ERRORS
-The
-.Fn mount
-and
-.Fn nmount
-system calls will fail when one of the following occurs:
-.Bl -tag -width Er
-.It Bq Er EPERM

-.In mqueue.h
-.Ft int
-.Fn mq_notify "mqd_t mqdes" "const struct sigevent *notification"
-.Sh DESCRIPTION
-If the argument notification is not
-.Dv NULL ,
-this system call will register the calling process to be notified of message
-arrival at an empty message queue associated with the specified message
-queue descriptor,
-.Fa mqdes .
-The notification specified by the
-.Fa notification
-argument will be sent to
-the process when the message queue transitions from empty to non-empty.
-At any time, only one process may be registered for notification by a
-message queue.
-If the calling process or any other process has already
-registered for notification of message arrival at the specified message
-queue, subsequent attempts to register for that message queue will fail.
-.Pp
-The
-.Fa notification
-argument points to a
-.Vt sigevent
-structure that defines how the calling process will be notified.
-If
-.Fa notification->sigev_notify
-is
-.Dv SIGEV_NONE ,
-then no signal will be posted, but the error status and the return status
-for the operation will be set appropriately.
-If
-.Fa notification->sigev_notify
-is
-.Dv SIGEV_SIGNAL ,
-then the signal specified in
-.Fa notification->sigev_signo
-will be sent to the process.
-The signal will be queued to the process and the value specified in
-.Fa notification->sigev_value
-will be the
-.Va si_value
-component of the generated signal.
-.Pp
-If
-.Fa notification
-is
-.Dv NULL
-and the process is currently registered for notification by the specified
-message queue, the existing registration will be removed.
-.Pp
-When the notification is sent to the registered process, its registration
-is removed.
-The message queue then is available for registration.
-.Pp
-If a process has registered for notification of message arrival at a
-message queue and some thread is blocked in
-.Fn mq_receive
-waiting to receive a message when a message arrives at the queue, the
-arriving message will satisfy the appropriate
-.Fn mq_receive .
-The resulting behavior is as if the message queue remains empty, and no

-.Sh NAME
-.Nm mq_open
-.Nd "open a message queue (REALTIME)"
-.Sh LIBRARY
-.Lb librt
-.Sh SYNOPSIS
-.In mqueue.h
-.Ft mqd_t
-.Fn mq_open "const char *name" "int oflag" "..."
-.Sh DESCRIPTION
-The
-.Fn mq_open
-system call establishes the connection between a process and a message queue
-with a message queue descriptor.
-It creates an open message queue
-description that refers to the message queue, and a message queue descriptor
-that refers to that open message queue description.
-The message queue
-descriptor is used by other functions to refer to that message queue.
-The
-.Fa name
-argument points to a string naming a message queue.
-The
-.Fa name
-argument should conform to the construction rules for a pathname.
-The
-.Fa name
-should begin with a slash character.
-Processes calling
-.Fn mq_open
-with the same value of
-.Fa name
-refers to the same message queue object, as long as that name has not been
-removed.
-If the
-.Fa name
-argument is not the name of an existing message queue and creation is not
-requested,
-.Fn mq_open
-will fail and return an error.
-.Pp
-The
-.Fa oflag
-argument requests the desired receive and/or send access to the message
-queue.
-The requested access permission to receive messages or send messages
-would be granted if the calling process would be granted read or write access,
-respectively, to an equivalently protected file.
-.Pp
-The value of
-.Fa oflag
-is the bitwise-inclusive OR of values from the following list.
-Applications should specify exactly one of the first three values (access
-modes) below in the value of
-.Fa oflag :
-.Bl -tag -width ".Dv O_NONBLOCK"
-.It Dv O_RDONLY
-Open the message queue for receiving messages.
-The process can use the
-returned message queue descriptor with
-.Fn mq_receive ,
-but not
-.Fn mq_send .
-A message queue may be open multiple times in the same or different processes
-for receiving messages.
-.It Dv O_WRONLY
-Open the queue for sending messages.
-The process can use the returned
-message queue descriptor with
-.Fn mq_send
-but not
-.Fn mq_receive .
-A message queue may be open multiple times in the same or different processes
-for sending messages.
-.It Dv O_RDWR
-Open the queue for both receiving and sending messages.
-The process can use
-any of the functions allowed for
-.Dv O_RDONLY
-and
-.Dv O_WRONLY .
-A message queue may be open multiple times in the same or different processes
-for sending messages.
-.El
-.Pp
-Any combination of the remaining flags may be specified in the value of
-.Fa oflag :
-.Bl -tag -width ".Dv O_NONBLOCK"
-.It Dv O_CREAT
-Create a message queue.
-It requires two additional arguments:
-.Fa mode ,
-which is of type
-.Vt mode_t ,
-and
-.Fa attr ,
-which is a pointer to an
-.Vt mq_attr
-structure.
-If the pathname
-.Fa name
-has already been used to create a message queue that still exists, then
-this flag has no effect, except as noted under
-.Dv O_EXCL .
-Otherwise, a message queue will be created without any messages
-in it.
-The user ID of the message queue will be set to the effective user ID
-of the process, and the group ID of the message queue will be set to the
-effective group ID of the process.
-The permission bits of the message queue
-will be set to the value of the
-.Fa mode
-argument, except those set in the file mode creation mask of the process.
-When bits in
-.Fa mode
-other than the file permission bits are specified, the effect is
-unspecified.
-If
-.Fa attr
-is
-.Dv NULL ,
-the message queue is created with implementation-defined default message
-queue attributes.
-If attr is
-.Pf non- Dv NULL
-and the calling process has the
-appropriate privilege on name, the message queue
-.Va mq_maxmsg
-and
-.Va mq_msgsize
-attributes will be set to the values of the corresponding members in the
-.Vt mq_attr
-structure referred to by
-.Fa attr .
-If
-.Fa attr
-is
-.Pf non- Dv NULL ,
-but the calling process does not have the appropriate privilege
-on name, the
-.Fn mq_open
-function will fail and return an error without creating the message queue.
-.It Dv O_EXCL
-If
-.Dv O_EXCL
-and
-.Dv O_CREAT
-are set,
-.Fn mq_open
-will fail if the message queue name exists.
-.It Dv O_NONBLOCK
-Determines whether an
-.Fn mq_send
-or
-.Fn mq_receive
-waits for resources or messages that are not currently available, or fails
-with
-.Va errno
-set to
-.Er EAGAIN ;
-see
-.Xr mq_send 2
-and
-.Xr mq_receive 2
-for details.
-.El
-.Pp
-The
-.Fn mq_open
-system call does not add or remove messages from the queue.
-.Sh NOTES
-.Fx
-implements message queue based on file descriptor.
-The descriptor
-is inherited by child after
-.Xr fork 2 .
-The descriptor is closed in a new image after
-.Xr exec 3 .
-The
-.Xr select 2
-and
-.Xr kevent 2
-system calls are supported for message queue descriptor.
-.Sh RETURN VALUES
-Upon successful completion, the function returns a message queue
-descriptor; otherwise, the function returns

-.Va errno
-to indicate the error.

-.Sh DESCRIPTION
-The
-.Fn mq_receive
-system call receives oldest of the highest priority message(s) from the
-message queue specified by
-.Fa mqdes .
-If the size of the buffer in bytes, specified by the
-.Fa msg_len
-argument, is less than the
-.Va mq_msgsize
-attribute of the message queue, the system call will fail and return an
-error.
-Otherwise, the selected message will be removed from the queue
-and copied to the buffer pointed to by the
-.Fa msg_ptr
-argument.
-.Pp
-If the argument
-.Fa msg_prio
-is not
-.Dv NULL ,
-the priority of the selected message will be stored in the
-location referenced by
-.Fa msg_prio .
-If the specified message queue is empty and
-.Dv O_NONBLOCK
-is not set in the message queue description associated with
-.Fa mqdes ,
-.Fn mq_receive
-will block until a message is enqueued on the message queue or until
-.Fn mq_receive
-is interrupted by a signal.
-If more than one thread is waiting to receive
-a message when a message arrives at an empty queue and the Priority
-Scheduling option is supported, then the thread of highest priority that
-has been waiting the longest will be selected to receive the message.
-Otherwise, it is unspecified which waiting thread receives the message.
-If the specified message queue is empty and
-.Dv O_NONBLOCK
-is set in the message queue description associated with
-.Fa mqdes ,
-no message
-will be removed from the queue, and
-.Fn mq_receive
-will return an error.
-.Pp
-The
-.Fn mq_timedreceive
-system call will receive the oldest of the highest priority messages from the
-message queue specified by
-.Fa mqdes
-as described for the
-.Fn mq_receive
-system call.
-However, if
-.Dv O_NONBLOCK
-was not specified when the message queue was opened via the
-.Fn mq_open
-system call, and no message exists on the queue to satisfy the receive, the wait
-for such a message will be terminated when the specified timeout expires.
-If
-.Dv O_NONBLOCK
-is set, this system call is equivalent to
-.Fn mq_receive .
-.Pp
-The timeout expires when the absolute time specified by
-.Fa abs_timeout
-passes, as measured by the clock on which timeouts are based (that is, when
-the value of that clock equals or exceeds
-.Fa abs_timeout ) ,
-or if the absolute time specified by
-.Fa abs_timeout
-has already been passed at the time of the call.
-.Pp
-The timeout is based on the
-.Dv CLOCK_REALTIME
-clock.
-.Sh RETURN VALUES
-Upon successful completion, the
-.Fn mq_receive
-and
-.Fn mq_timedreceive
-system calls return the length of the selected message in bytes and the
-message is removed from the queue.
-Otherwise, no message is removed
-from the queue, the system call returns a value of \-1,
-and the global variable
-.Va errno
-is set to indicate the error.

-.Nd "send a message to message queue (REALTIME)"
-.Sh LIBRARY
-.Lb librt
-.Sh SYNOPSIS
-.In mqueue.h
-.Ft int

-.Fa "const char *msg_ptr"
-.Fa "size_t msg_len"
-.Fa "unsigned msg_prio"

-.Fa "mqd_t mqdes"
-.Fa "const char *msg_ptr"
-.Fa "size_t msg_len"
-.Fa "unsigned msg_prio"
-.Fa "const struct timespec *abs_timeout"
-.Fc
-.Sh DESCRIPTION
-The
-.Fn mq_send
-system call adds the message pointed to by the argument
-.Fa msg_ptr
-to the message queue specified by
-.Fa mqdes .
-The
-.Fa msg_len
-argument specifies the length of the message, in bytes, pointed to by
-.Fa msg_ptr .
-The value of
-.Fa msg_len
-should be less than or equal to the
-.Va mq_msgsize
-attribute of the message queue, or
-.Fn mq_send
-will fail.
-.Pp
-If the specified message queue is not full,
-.Fn mq_send
-will behave as if the message is inserted into the message queue at
-the position indicated by the
-.Fa msg_prio
-argument.
-A message with a larger numeric value of
-.Fa msg_prio
-will be inserted before messages with lower values of
-.Fa msg_prio .
-A message will be inserted after other messages in the queue, if any,
-with equal
-.Fa msg_prio .
-The value of
-.Fa msg_prio
-should be less than
-.Brq Dv MQ_PRIO_MAX .
-.Pp
-If the specified message queue is full and
-.Dv O_NONBLOCK
-is not set in the message queue description associated with
-.Fa mqdes ,
-.Fn mq_send
-will block until space becomes available to enqueue the
-message, or until
-.Fn mq_send
-is interrupted by a signal.
-If more than one thread is
-waiting to send when space becomes available in the message queue and
-the Priority Scheduling option is supported, then the thread of the
-highest priority that has been waiting the longest will be unblocked
-to send its message.
-Otherwise, it is unspecified which waiting thread
-is unblocked.
-If the specified message queue is full and
-.Dv O_NONBLOCK
-is set in the message queue description associated with
-.Fa mqdes ,
-the message will not be queued and
-.Fn mq_send
-will return an error.
-.Pp
-The
-.Fn mq_timedsend
-system call will add a message to the message queue specified by
-.Fa mqdes
-in the manner defined for the
-.Fn mq_send
-system call.
-However, if the specified message queue is full and
-.Dv O_NONBLOCK
-is not set in the message queue description associated with
-.Fa mqdes ,
-the wait for sufficient room in the queue will be terminated when
-the specified timeout expires.
-If
-.Dv O_NONBLOCK
-is set in the message queue description, this system call is
-equivalent to
-.Fn mq_send .
-.Pp
-The timeout will expire when the absolute time specified by
-.Fa abs_timeout
-passes, as measured by the clock on which timeouts are based (that is,
-when the value of that clock equals or exceeds
-.Fa abs_timeout ) ,
-or if the absolute time specified by
-.Fa abs_timeout
-has already been passed at the time of the call.
-.Pp
-The timeout is based on the
-.Dv CLOCK_REALTIME
-clock.
-.Sh RETURN VALUES
-Upon successful completion, the
-.Fn mq_send
-and
-.Fn mq_timedsend
-system calls return a value of zero.
-Otherwise, no message will be
-enqueued, the system calls return \-1, and
-the global variable
-.Va errno
-is set to indicate the error.
-.Sh ERRORS
-The
-.Fn mq_send
-and
-.Fn mq_timedsend
-system calls
-will fail if:
-.Bl -tag -width Er
-.It Bq Er EAGAIN
-The
-.Dv O_NONBLOCK

-.Sh DESCRIPTION
-The

-system call performs some control operations on the message queue specified
-by
-.Fa msqid .
-.Pp
-Each message queue has a data structure associated with it, parts of which
-may be altered by
-.Fn msgctl
-and parts of which determine the actions of
-.Fn msgctl .
-The data structure is defined in
-.In sys/msg.h
-and contains (amongst others) the following members:
-.Bd -literal
-struct msqid_ds {
- struct ipc_perm msg_perm; /* msg queue permission bits */
- struct msg *msg_first; /* first message in the queue */
- struct msg *msg_last; /* last message in the queue */

- time_t msg_rtime; /* time of last msgrcv() */
- time_t msg_ctime; /* time of last msgctl() */
-};
-.Ed
-.Pp
-The
-.Vt ipc_perm
-structure used inside the
-.Vt msqid_ds
-structure is defined in
-.In sys/ipc.h
-and looks like this:
-.Bd -literal
-struct ipc_perm {
- uid_t cuid; /* creator user id */
- gid_t cgid; /* creator group id */
- uid_t uid; /* user id */
- gid_t gid; /* group id */
- mode_t mode; /* r/w permission */
- unsigned short seq; /* sequence # (to generate unique ipcid) */
- key_t key; /* user specified msg/sem/shm key */
-};
-.Ed
-.Pp
-The operation to be performed by
-.Fn msgctl
-is specified in
-.Fa cmd
-and is one of:
-.Bl -tag -width IPC_RMIDX
-.It Dv IPC_STAT
-Gather information about the message queue and place it in the
-structure pointed to by
-.Fa buf .

-Set the value of the
-.Va msg_perm.uid ,
-.Va msg_perm.gid ,
-.Va msg_perm.mode
-and
-.Va msg_qbytes
-fields in the structure associated with
-.Fa msqid .
-The values are taken from the corresponding fields in the structure
-pointed to by
-.Fa buf .
-This operation can only be executed by the super-user, or a process that
-has an effective user id equal to either
-.Va msg_perm.cuid
-or
-.Va msg_perm.uid
-in the data structure associated with the message queue.
-The value of
-.Va msg_qbytes
-can only be increased by the super-user.
-Values for
-.Va msg_qbytes
-that exceed the system limit (MSGMNB from
-.In sys/msg.h )
-are silently truncated to that limit.
-.It Dv IPC_RMID

-Only the super-user or a process
-with an effective uid equal to the

-This structure should consist of the following members:
-.Bd -literal
- long mtype; /* message type */
- char mtext[1]; /* body of message */
-.Ed
-.Pp
-.Va mtype
-is an integer greater than 0 that can be used for selecting messages,
-.Va mtext
-is an array of bytes, with a size up to that of the system limit
-.Pf ( Dv MSGMAX ) .
-.Pp
-The value of
-.Fa msgtyp
-has one of the following meanings:

-The first message of the lowest message type that is
-less than or equal to the absolute value of
-.Fa msgtyp
-will be received.
-.El
-.Pp
-The
-.Fa msgsz
-argument
-specifies the maximum length of the requested message.
-If the received
-message has a length greater than
-.Fa msgsz
-it will be silently truncated if the
-.Dv MSG_NOERROR
-flag is set in
-.Fa msgflg ,
-otherwise an error will be returned.
-.Pp
-If no matching message is present on the message queue specified by
-.Fa msqid ,
-the behavior of
-.Fn msgrcv
-depends on whether the
-.Dv IPC_NOWAIT
-flag is set in
-.Fa msgflg
-or not.
-If
-.Dv IPC_NOWAIT
-is set,
-.Fn msgrcv
-will immediately return a value of -1, and set
-.Va errno

-.It
-A message of the requested type becomes available on the message queue.
-.It
-The message queue is removed, in which case -1 will be returned, and
-.Va errno
-set to
-.Er EINVAL .
-.It
-A signal is received and caught.
--1 is returned, and
-.Va errno
-set to
-.Er EINTR .
-.El
-.Pp
-If a message is successfully received, the data structure associated with
-.Fa msqid
-is updated as follows:
-.Bl -bullet
-.It
-.Va msg_cbytes
-is decremented by the size of the message.
-.It
-.Va msg_lrpid
-is set to the pid of the caller.
-.It
-.Va msg_lrtime
-is set to the current time.
-.It
-.Va msg_qnum
-is decremented by 1.

-.Sh RETURN VALUES
-Upon successful completion,
-.Fn msgrcv
-returns the number of bytes received into the
-.Va mtext
-field of the structure pointed to by
-.Fa msgp .
-Otherwise, -1 is returned, and
-.Va errno
-set to indicate the error.

-to adjust the phase and frequency of the phase- or frequency-lock loop
-(PLL resp. FLL) which controls the system clock.
-.Pp
-The
-.Fn ntp_gettime
-function provides the time, maximum error (sync distance) and
-estimated error (dispersion) to client user application programs.
-.Pp
-In the following, all variables that refer PPS are only relevant if
-the
-.Em PPS_SYNC
-option is enabled in the kernel.
-.Pp
-.Fn ntp_adjtime
-has as argument a

-.Dt OPEN 2
-.Os
-.Sh NAME
-.Nm open , openat
-.Nd open or create a file for reading, writing or executing
-.Sh LIBRARY
-.Lb libc
-.Sh SYNOPSIS
-.In fcntl.h
-.Ft int
-.Fn open "const char *path" "int flags" "..."
-.Ft int
-.Fn openat "int fd" "const char *path" "int flags" "..."
-.Sh DESCRIPTION
-The file name specified by
-.Fa path
-is opened
-for either execution or reading and/or writing as specified by the
-argument
-.Fa flags
-and the file descriptor returned to the calling process.
-The
-.Fa flags
-argument may indicate the file is to be
-created if it does not exist (by specifying the
-.Dv O_CREAT
-flag).
-In this case
-.Fn open
-and
-.Fn openat
-require an additional argument
-.Fa "mode_t mode" ,
-and the file is created with mode
-.Fa mode
-as described in
-.Xr chmod 2
-and modified by the process' umask value (see
-.Xr umask 2 ) .
-.Pp
-The
-.Fn openat
-function is equivalent to the
-.Fn open
-function except in the case where the
-.Fa path
-specifies a relative path.
-In this case the file to be opened is determined relative to the directory
-associated with the file descriptor
-.Fa fd
-instead of the current working directory.
-The
-.Fa flag
-parameter and the optional fourth parameter correspond exactly to
-the parameters of
-.Fn open .
-If
-.Fn openat
-is passed the special value
-.Dv AT_FDCWD
-in the
-.Fa fd
-parameter, the current working directory is used
-and the behavior is identical to a call to
-.Fn open .
-.Pp
-The flags specified are formed by
-.Em or Ns 'ing
-the following values
-.Pp
-.Bd -literal -offset indent -compact
-O_RDONLY open for reading only
-O_WRONLY open for writing only
-O_RDWR open for reading and writing
-O_EXEC open for execute only
-O_NONBLOCK do not block on open
-O_APPEND append on each write
-O_CREAT create file if it does not exist
-O_TRUNC truncate size to 0
-O_EXCL error if create and file exists
-O_SHLOCK atomically obtain a shared lock
-O_EXLOCK atomically obtain an exclusive lock
-O_DIRECT eliminate or reduce cache effects
-O_FSYNC synchronous writes
-O_SYNC synchronous writes
-O_NOFOLLOW do not follow symlinks
-O_NOCTTY don't assign controlling terminal
-O_TTY_INIT restore default terminal attributes
-O_DIRECTORY error if file is not a directory
-.Ed
-.Pp
-Opening a file with
-.Dv O_APPEND
-set causes each write on the file
-to be appended to the end.
-If
-.Dv O_TRUNC
-is specified and the
-file exists, the file is truncated to zero length.
-If
-.Dv O_EXCL
-is set with
-.Dv O_CREAT
-and the file already
-exists,
-.Fn open
-returns an error.
-This may be used to
-implement a simple exclusive access locking mechanism.
-If
-.Dv O_EXCL
-is set and the last component of the pathname is
-a symbolic link,
-.Fn open
-will fail even if the symbolic
-link points to a non-existent name.
-If the
-.Dv O_NONBLOCK
-flag is specified and the
-.Fn open
-system call would result
-in the process being blocked for some reason (e.g., waiting for
-carrier on a dialup line),
-.Fn open
-returns immediately.
-The descriptor remains in non-blocking mode for subsequent operations.
-.Pp
-If
-.Dv O_FSYNC
-is used in the mask, all writes will
-immediately be written to disk,
-the kernel will not cache written data
-and all writes on the descriptor will not return until
-the data to be written completes.
-.Pp
-.Dv O_SYNC
-is a synonym for
-.Dv O_FSYNC
-required by
-.Tn POSIX .
-.Pp
-If
-.Dv O_NOFOLLOW
-is used in the mask and the target file passed to
-.Fn open
-is a symbolic link then the
-.Fn open
-will fail.
-.Pp
-When opening a file, a lock with
-.Xr flock 2
-semantics can be obtained by setting
-.Dv O_SHLOCK
-for a shared lock, or
-.Dv O_EXLOCK
-for an exclusive lock.
-If creating a file with
-.Dv O_CREAT ,
-the request for the lock will never fail
-(provided that the underlying file system supports locking).
-.Pp
-.Dv O_DIRECT
-may be used to minimize or eliminate the cache effects of reading and writing.
-The system will attempt to avoid caching the data you read or write.
-If it cannot avoid caching the data,
-it will minimize the impact the data has on the cache.
-Use of this flag can drastically reduce performance if not used with care.
-.Pp
-.Dv O_NOCTTY
-may be used to ensure the OS does not assign this file as the
-controlling terminal when it opens a tty device.
-This is the default on
-.Fx ,
-but is present for
-.Tn POSIX
-compatibility.
-The
-.Fn open
-system call will not assign controlling terminals on
-.Fx .
-.Pp
-.Dv O_TTY_INIT
-may be used to ensure the OS restores the terminal attributes when
-initially opening a TTY.
-This is the default on
-.Fx ,
-but is present for
-.Tn POSIX
-compatibility.
-The initial call to
-.Fn open
-on a TTY will always restore default terminal attributes on
-.Fx .
-.Pp
-.Dv O_DIRECTORY
-may be used to ensure the resulting file descriptor refers to a
-directory.
-This flag can be used to prevent applications with elevated privileges
-from opening files which are even unsafe to open with
-.Dv O_RDONLY ,
-such as device nodes.
-.Pp
-If successful,
-.Fn open
-returns a non-negative integer, termed a file descriptor.
-It returns \-1 on failure.
-The file pointer used to mark the current position within the
-file is set to the beginning of the file.
-.Pp
-When a new file is created it is given the group of the directory
-which contains it.
-.Pp
-The new descriptor is set to remain open across
-.Xr execve 2
-system calls; see
-.Xr close 2
-and
-.Xr fcntl 2 .
-.Pp
-The system imposes a limit on the number of file descriptors
-open simultaneously by one process.
-The
-.Xr getdtablesize 2
-system call returns the current system limit.
-.Sh RETURN VALUES
-If successful,
-.Fn open
-and
-.Fn openat
-return a non-negative integer, termed a file descriptor.
-They return \-1 on failure, and set
-.Va errno
-to indicate the error.
-.Sh ERRORS

-.Sh DESCRIPTION
-The
-.Fn pathconf ,
-.Fn lpathconf
-and
-.Fn fpathconf
-system calls provide a method for applications to determine the current
-value of a configurable system limit or option variable associated
-with a pathname or file descriptor.
-.Pp
-For
-.Fn pathconf
-and

-system call is like
-.Fn pathconf
-except in the case where the named file is a symbolic link,
-in which case
-.Fn lpathconf
-returns information about the link,
-while
-.Fn pathconf
-returns information about the file the link references.
-.Pp
-The available values are as follows:
-.Pp
-.Bl -tag -width 6n

-.Fn pathconf
-and
-.Fn fpathconf
-return a positive number that represents the minimum hole size returned in
-bytes.
-The offsets of holes returned will be aligned to this same value.
-A special value of 1 is returned if the file system does not specify the minimum
-hole size but still reports holes.
-.El
-.Sh RETURN VALUES
-If the call to

-.Sh LIBRARY

-.Sh SYNOPSIS
-.In unistd.h
-.Ft int
-.Fn pipe "int fildes[2]"
-.Sh DESCRIPTION
-The
-.Fn pipe
-system call
-creates a
-.Em pipe ,
-which is an object allowing
-bidirectional data flow,
-and allocates a pair of file descriptors.
-.Pp
-By convention, the first descriptor is normally used as the
-.Em read end
-of the pipe,
-and the second is normally the
-.Em write end ,
-so that data written to
-.Fa fildes[1]
-appears on (i.e., can be read from)
-.Fa fildes[0] .
-This allows the output of one program to be
-sent
-to another program:
-the source's standard output is set up to be
-the write end of the pipe,
-and the sink's standard input is set up to be
-the read end of the pipe.
-The pipe itself persists until all its associated descriptors are
-closed.
-.Pp
-A pipe that has had an end closed is considered
-.Em widowed .
-Writing on such a pipe causes the writing process to receive
-a
-.Dv SIGPIPE
-signal.
-Widowing a pipe is the only way to deliver end-of-file to a reader:
-after the reader consumes any buffered data, reading a widowed pipe
-returns a zero count.
-.Pp
-The bidirectional nature of this implementation of pipes is not
-portable to older systems, so it is recommended to use the convention
-for using the endpoints in the traditional manner when using a
-pipe in one direction.
-.Sh RETURN VALUES
-.Rv -std pipe
-.Sh ERRORS
-The
-.Fn pipe
-system call will fail if:
-.Bl -tag -width Er
-.It Bq Er EMFILE
-Too many descriptors are active.

-.Sh SYNOPSIS
-.In poll.h
-.Ft int
-.Fn poll "struct pollfd fds[]" "nfds_t nfds" "int timeout"
-.Sh DESCRIPTION
-The
-.Fn poll
-system call
-examines a set of file descriptors to see if some of them are ready for
-I/O.
-The
-.Fa fds
-argument is a pointer to an array of pollfd structures as defined in
-.In poll.h
-(shown below).
-The
-.Fa nfds
-argument determines the size of the
-.Fa fds
-array.
-.Bd -literal
-struct pollfd {
- int fd; /* file descriptor */
- short events; /* events to look for */
- short revents; /* events returned */
-};
-.Ed
-.Pp
-The fields of
-.Fa struct pollfd
-are as follows:
-.Bl -tag -width XXXrevents
-.It fd
-File descriptor to poll.
-If fd is equal to -1 then
-.Fa revents
-is cleared (set to zero), and that pollfd is not checked.
-.It events
-Events to poll for.
-(See below.)
-.It revents
-Events which may occur.
-(See below.)
-.El
-.Pp
-The event bitmasks in
-.Fa events
-and
-.Fa revents
-have the following bits:
-.Bl -tag -width XXXPOLLWRNORM
-.It POLLIN
-Data other than high priority data may be read without blocking.
-.It POLLRDNORM
-Normal data may be read without blocking.
-.It POLLRDBAND
-Data with a non-zero priority may be read without blocking.
-.It POLLPRI
-High priority data may be read without blocking.
-.It POLLOUT
-.It POLLWRNORM
-Normal data may be written without blocking.
-.It POLLWRBAND
-Data with a non-zero priority may be written without blocking.
-.It POLLERR
-An exceptional condition has occurred on the device or socket.
-This
-flag is always checked, even if not present in the
-.Fa events
-bitmask.
-.It POLLHUP
-The device or socket has been disconnected.
-This flag is always
-checked, even if not present in the
-.Fa events
-bitmask.
-Note that
-POLLHUP
-and
-POLLOUT
-should never be present in the
-.Fa revents
-bitmask at the same time.
-.It POLLNVAL
-The file descriptor is not open.
-This flag is always checked, even
-if not present in the
-.Fa events
-bitmask.
-.El
-.Pp
-If
-.Fa timeout
-is neither zero nor INFTIM (-1), it specifies a maximum interval to
-wait for any file descriptor to become ready, in milliseconds.
-If
-.Fa timeout
-is INFTIM (-1), the poll blocks indefinitely.
-If
-.Fa timeout
-is zero, then
-.Fn poll
-will return without blocking.
-.Sh RETURN VALUES
-The
-.Fn poll
-system call
-returns the number of descriptors that are ready for I/O, or -1 if an
-error occurred.
-If the time limit expires,
-.Fn poll
-returns 0.
-If
-.Fn poll
-returns with an error,
-including one due to an interrupted system call,
-the
-.Fa fds
-array will be unmodified.
-.Sh COMPATIBILITY
-This implementation differs from the historical one in that a given
-file descriptor may not cause
-.Fn poll
-to return with an error.
-In cases where this would have happened in
-the historical implementation (e.g.\& trying to poll a
-.Xr revoke 2 Ns ed
-descriptor), this implementation instead copies the
-.Fa events
-bitmask to the
-.Fa revents
-bitmask.
-Attempting to perform I/O on this descriptor will then
-return an error.
-This behaviour is believed to be more useful.
-.Sh ERRORS
-An error return from
-.Fn poll
-indicates:
-.Bl -tag -width Er
-.It Bq Er EFAULT
-The
-.Fa fds
-argument
-points outside the process's allocated address space.
-.It Bq Er EINTR
-A signal was delivered before the time limit expired and
-before any of the selected events occurred.
-.It Bq Er EINVAL
-The specified time limit is negative.

-.Sh HISTORY
-The

-This manual page and the core of the implementation was taken from
-.Nx .
-.Sh BUGS
-The distinction between some of the fields in the
-.Fa events

-bitmasks is really not useful without STREAMS.
-The fields are
-defined for compatibility with existing software.

-.Ft int
-.Fn profil "char *samples" "size_t size" "vm_offset_t offset" "int scale"
-.Sh DESCRIPTION
-The
-.Fn profil
-system call enables or disables
-program counter profiling of the current process.
-If profiling is enabled,
-then at every profiling clock tick,
-the kernel updates an appropriate count in the
-.Fa samples
-buffer.
-The frequency of the profiling clock is recorded
-in the header in the profiling output file.
-.Pp
-The buffer
-.Fa samples
-contains
-.Fa size
-bytes and is divided into
-a series of 16-bit bins.
-Each bin counts the number of times the program counter
-was in a particular address range in the process
-when a profiling clock tick occurred while profiling was enabled.
-For a given program counter address,
-the number of the corresponding bin is given
-by the relation:
-.Bd -literal -offset indent
-[(pc - offset) / 2] * scale / 65536
-.Ed
-.Pp
-The
-.Fa offset
-argument is the lowest address at which
-the kernel takes program counter samples.
-The
-.Fa scale
-argument ranges from 1 to 65536 and
-can be used to change the span of the bins.
-A scale of 65536 maps each bin to 2 bytes of address range;
-a scale of 32768 gives 4 bytes, 16384 gives 8 bytes and so on.
-Intermediate values provide approximate intermediate ranges.
-A
-.Fa scale
-value of 0 disables profiling.

-.Dt PTRACE 2
-.Os
-.Sh NAME
-.Nm ptrace
-.Nd process tracing and debugging
-.Sh LIBRARY
-.Lb libc
-.Sh SYNOPSIS
-.In sys/types.h
-.In sys/ptrace.h
-.Ft int
-.Fn ptrace "int request" "pid_t pid" "caddr_t addr" "int data"
-.Sh DESCRIPTION
-The
-.Fn ptrace
-system call
-provides tracing and debugging facilities.
-It allows one process
-(the
-.Em tracing
-process)
-to control another
-(the
-.Em traced
-process).
-The tracing process must first attach to the traced process, and then
-issue a series of
-.Fn ptrace
-system calls to control the execution of the process, as well as access
-process memory and register state.
-For the duration of the tracing session, the traced process will be
-.Dq re-parented ,
-with its parent process ID (and resulting behavior)
-changed to the tracing process.
-It is permissible for a tracing process to attach to more than one
-other process at a time.
-When the tracing process has completed its work, it must detach the
-traced process; if a tracing process exits without first detaching all
-processes it has attached, those processes will be killed.
-.Pp
-Most of the time, the traced process runs normally, but when it
-receives a signal
-(see
-.Xr sigaction 2 ) ,
-it stops.
-The tracing process is expected to notice this via
-.Xr wait 2
-or the delivery of a
-.Dv SIGCHLD
-signal, examine the state of the stopped process, and cause it to
-terminate or continue as appropriate.
-The signal may be a normal process signal, generated as a result of
-traced process behavior, or use of the
-.Xr kill 2
-system call; alternatively, it may be generated by the tracing facility
-as a result of attaching, system calls, or stepping by the tracing
-process.
-The tracing process may choose to intercept the signal, using it to
-observe process behavior (such as
-.Dv SIGTRAP ) ,
-or forward the signal to the process if appropriate.
-The
-.Fn ptrace
-system call
-is the mechanism by which all this happens.
-.Pp
-The
-.Fa request
-argument specifies what operation is being performed; the meaning of
-the rest of the arguments depends on the operation, but except for one
-special case noted below, all
-.Fn ptrace
-calls are made by the tracing process, and the
-.Fa pid
-argument specifies the process ID of the traced process
-or a corresponding thread ID.
-The
-.Fa request
-argument
-can be:
-.Bl -tag -width 12n
-.It Dv PT_TRACE_ME
-This request is the only one used by the traced process; it declares
-that the process expects to be traced by its parent.
-All the other arguments are ignored.
-(If the parent process does not expect to trace the child, it will
-probably be rather confused by the results; once the traced process
-stops, it cannot be made to continue except via
-.Fn ptrace . )
-When a process has used this request and calls
-.Xr execve 2
-or any of the routines built on it
-(such as
-.Xr execv 3 ) ,
-it will stop before executing the first instruction of the new image.
-Also, any setuid or setgid bits on the executable being executed will
-be ignored.
-.It Dv PT_READ_I , Dv PT_READ_D
-These requests read a single
-.Vt int
-of data from the traced process's address space.
-Traditionally,
-.Fn ptrace
-has allowed for machines with distinct address spaces for instruction
-and data, which is why there are two requests: conceptually,
-.Dv PT_READ_I
-reads from the instruction space and
-.Dv PT_READ_D
-reads from the data space.
-In the current
-.Fx
-implementation, these two requests are completely identical.
-The
-.Fa addr
-argument specifies the address
-(in the traced process's virtual address space)
-at which the read is to be done.
-This address does not have to meet any alignment constraints.
-The value read is returned as the return value from
-.Fn ptrace .
-.It Dv PT_WRITE_I , Dv PT_WRITE_D
-These requests parallel
-.Dv PT_READ_I
-and
-.Dv PT_READ_D ,
-except that they write rather than read.
-The
-.Fa data
-argument supplies the value to be written.
-.It Dv PT_IO
-This request allows reading and writing arbitrary amounts of data in
-the traced process's address space.
-The
-.Fa addr
-argument specifies a pointer to a
-.Vt "struct ptrace_io_desc" ,
-which is defined as follows:
-.Bd -literal
-struct ptrace_io_desc {
- int piod_op; /* I/O operation */
- void *piod_offs; /* child offset */
- void *piod_addr; /* parent offset */
- size_t piod_len; /* request length */
-};
-
-/*
- * Operations in piod_op.
- */
-#define PIOD_READ_D 1 /* Read from D space */
-#define PIOD_WRITE_D 2 /* Write to D space */
-#define PIOD_READ_I 3 /* Read from I space */
-#define PIOD_WRITE_I 4 /* Write to I space */
-.Ed
-.Pp
-The
-.Fa data
-argument is ignored.
-The actual number of bytes read or written is stored in
-.Va piod_len
-upon return.
-.It Dv PT_CONTINUE
-The traced process continues execution.
-The
-.Fa addr
-argument
-is an address specifying the place where execution is to be resumed
-(a new value for the program counter),
-or
-.Po Vt caddr_t Pc Ns 1
-to indicate that execution is to pick up where it left off.
-The
-.Fa data
-argument
-provides a signal number to be delivered to the traced process as it
-resumes execution, or 0 if no signal is to be sent.
-.It Dv PT_STEP
-The traced process is single stepped one instruction.
-The
-.Fa addr
-argument
-should be passed
-.Po Vt caddr_t Pc Ns 1 .
-The
-.Fa data
-argument
-provides a signal number to be delivered to the traced process as it
-resumes execution, or 0 if no signal is to be sent.
-.It Dv PT_KILL
-The traced process terminates, as if
-.Dv PT_CONTINUE
-had been used with
-.Dv SIGKILL
-given as the signal to be delivered.
-.It Dv PT_ATTACH
-This request allows a process to gain control of an otherwise
-unrelated process and begin tracing it.
-It does not need any cooperation from the to-be-traced process.
-In
-this case,
-.Fa pid
-specifies the process ID of the to-be-traced process, and the other
-two arguments are ignored.
-This request requires that the target process must have the same real
-UID as the tracing process, and that it must not be executing a setuid
-or setgid executable.
-(If the tracing process is running as root, these restrictions do not
-apply.)
-The tracing process will see the newly-traced process stop and may
-then control it as if it had been traced all along.
-.It Dv PT_DETACH
-This request is like PT_CONTINUE, except that it does not allow
-specifying an alternate place to continue execution, and after it
-succeeds, the traced process is no longer traced and continues
-execution normally.
-.It Dv PT_GETREGS
-This request reads the traced process's machine registers into the
-.Do
-.Vt "struct reg"
-.Dc
-(defined in
-.In machine/reg.h )
-pointed to by
-.Fa addr .
-.It Dv PT_SETREGS

-.It Dv PT_LWPINFO
-This request can be used to obtain information about the kernel thread,
-also known as light-weight process, that caused the traced process to stop.
-The
-.Fa addr
-argument specifies a pointer to a
-.Vt "struct ptrace_lwpinfo" ,
-which is defined as follows:
-.Bd -literal
-struct ptrace_lwpinfo {
- lwpid_t pl_lwpid;

-};
-.Ed
-.Pp
-The
-.Fa data
-argument is to be set to the size of the structure known to the caller.

-The thread stopped due to system call entry, right after the kernel is entered.
-The debugger may examine syscall arguments that are stored in memory and
-registers according to the ABI of the current process, and modify them,
-if needed.
-.It PL_FLAG_SCX
-The thread is stopped immediately before syscall is returning to the usermode.
-The debugger may examine system call return values in the ABI-defined registers
-and/or memory.
-.It PL_FLAG_EXEC
-When

-unmodified from the value returned by previous requests.
-The
-.Va pve_timestamp
-field can be used to detect changes to the VM map while iterating over the
-entries.
-The tracing process can then take appropriate action, such as restarting.
-By setting
-.Va pve_pathlen
-to a non-zero value on entry, the pathname of the backing object is returned
-in the buffer pointed to by

-.Sh SYNOPSIS
-.In sys/types.h
-.In ufs/ufs/quota.h
-.Ft int
-.Fn quotactl "const char *path" "int cmd" "int id" "void *addr"
-.Sh DESCRIPTION
-The
-.Fn quotactl
-system call enables, disables and
-manipulates file system quotas.
-A quota control command
-given by
-.Fa cmd
-operates on the given filename
-.Fa path
-for the given user or group
-.Fa id .
-(NOTE: One should use the QCMD macro defined in
-.In ufs/ufs/quota.h
-to formulate the value for
-.Fa cmd . )
-The address of an optional command specific data structure,
-.Fa addr ,
-may be given; its interpretation
-is discussed below with each command.
-.Pp
-For commands that use the
-.Fa id
-identifier, it must be either -1 or any positive value.
-The value of -1 indicates that the current UID or GID should be used.
-Any other negative value will return an error.
-.Pp
-Currently quotas are supported only for the
-.Dq ufs
-file system.
-For
-.Dq ufs ,
-a command is composed of a primary command (see below)
-and a command type used to interpret the
-.Fa id .
-Types are supported for interpretation of user identifiers (USRQUOTA)
-and group identifiers (GRPQUOTA).
-The
-.Dq ufs
-specific commands are:
-.Bl -tag -width Q_GETQUOTASIZEx
-.It Dv Q_QUOTAON
-Enable disk quotas for the file system specified by
-.Fa path .
-The command type specifies the type of the quotas being enabled.
-The
-.Fa addr
-argument specifies a file from which to take the quotas.
-The quota file must exist;
-it is normally created with the
-.Xr quotacheck 8
-program.
-The
-.Fa id
-argument is unused.
-Only the super-user may turn quotas on.
-.It Dv Q_QUOTAOFF
-Disable disk quotas for the file system specified by
-.Fa path .
-The command type specifies the type of the quotas being disabled.
-The
-.Fa addr
-and
-.Fa id
-arguments are unused.
-Only the super-user may turn quotas off.
-.It Dv Q_GETQUOTASIZE
-Get the wordsize used to represent the quotas for the user or group
-(as determined by the command type).
-Possible values are 32 for the old-style quota file
-and 64 for the new-style quota file.
-The
-.Fa addr
-argument is a pointer to an integer into which the size is stored.
-The identifier
-.Fa id
-is not used.
-.It Dv Q_GETQUOTA
-Get disk quota limits and current usage for the user or group
-(as determined by the command type) with identifier
-.Fa id .
-The
-.Fa addr
-argument
-is a pointer to a
-.Fa struct dqblk
-structure (defined in
-.In ufs/ufs/quota.h ) .
-.It Dv Q_SETQUOTA
-Set disk quota limits for the user or group
-(as determined by the command type) with identifier
-.Fa id .
-The
-.Fa addr
-argument
-is a pointer to a
-.Fa struct dqblk
-structure (defined in
-.In ufs/ufs/quota.h ) .
-The usage fields of the
-.Fa dqblk
-structure are ignored.
-This system call is restricted to the super-user.
-.It Dv Q_SETUSE
-Set disk usage limits for the user or group
-(as determined by the command type) with identifier
-.Fa id .
-The
-.Fa addr
-argument
-is a pointer to a
-.Fa struct dqblk
-structure (defined in
-.In ufs/ufs/quota.h ) .
-Only the usage fields are used.
-This system call is restricted to the super-user.
-.It Dv Q_SYNC
-Update the on-disk copy of quota usages.
-The command type specifies which type of quotas are to be updated.
-The
-.Fa id
-and
-.Fa addr
-arguments are ignored.

-.Ft ssize_t
-.Fn preadv "int d" "const struct iovec *iov" "int iovcnt" "off_t offset"
-.Sh DESCRIPTION
-The
-.Fn read
-system call
-attempts to read
-.Fa nbytes
-of data from the object referenced by the descriptor
-.Fa d
-into the buffer pointed to by
-.Fa buf .
-The
-.Fn readv
-system call
-performs the same action, but scatters the input data
-into the
-.Fa iovcnt
-buffers specified by the members of the
-.Fa iov
-array: iov[0], iov[1], ..., iov[iovcnt\|\-\|1].
-The
-.Fn pread
-and
-.Fn preadv
-system calls
-perform the same functions, but read from the specified position in
-the file without modifying the file pointer.
-.Pp
-For
-.Fn readv
-and
-.Fn preadv ,
-the
-.Fa iovec
-structure is defined as:
-.Pp
-.Bd -literal -offset indent -compact
-struct iovec {
- void *iov_base; /* Base address. */
- size_t iov_len; /* Length. */
-};
-.Ed
-.Pp
-Each
-.Fa iovec
-entry specifies the base address and length of an area
-in memory where data should be placed.
-The
-.Fn readv
-system call
-will always fill an area completely before proceeding
-to the next.
-.Pp
-On objects capable of seeking, the
-.Fn read
-starts at a position
-given by the pointer associated with
-.Fa d
-(see
-.Xr lseek 2 ) .
-Upon return from
-.Fn read ,
-the pointer is incremented by the number of bytes actually read.
-.Pp
-Objects that are not capable of seeking always read from the current
-position.
-The value of the pointer associated with such an
-object is undefined.
-.Pp
-Upon successful completion,
-.Fn read ,
-.Fn readv ,
-.Fn pread
-and
-.Fn preadv
-return the number of bytes actually read and placed in the buffer.
-The system guarantees to read the number of bytes requested if
-the descriptor references a normal file that has that many bytes left
-before the end-of-file, but in no other case.
-.Sh RETURN VALUES
-If successful, the
-number of bytes actually read is returned.
-Upon reading end-of-file,
-zero is returned.
-Otherwise, a -1 is returned and the global variable
-.Va errno
-is set to indicate the error.
-.Sh ERRORS
-The
-.Fn read ,
-.Fn readv ,
-.Fn pread
-and
-.Fn preadv
-system calls
-will succeed unless:

-argument
-points outside the allocated address space.
-.It Bq Er EIO
-An I/O error occurred while reading from the file system.
-.It Bq Er EINTR
-A read from a slow device
-(i.e.\& one that might block for an arbitrary amount of time)
-was interrupted by the delivery of a signal
-before any data arrived.
-.It Bq Er EINVAL
-The pointer associated with
-.Fa d
-was negative.
-.It Bq Er EAGAIN
-The file was marked for non-blocking I/O,
-and no data were ready to be read.
-.It Bq Er EISDIR
-The file descriptor is associated with a directory residing
-on a file system that does not allow regular read operations on
-directories (e.g.\& NFS).
-.It Bq Er EOPNOTSUPP
-The file descriptor is associated with a file system and file type that
-do not allow regular read operations on it.
-.It Bq Er EOVERFLOW
-The file descriptor is associated with a regular file,
-.Fa nbytes
-is greater than 0,
-.Fa offset

-is greater than or equal to the offset maximum established
-for this file system.
-.It Bq Er EINVAL
-The value
-.Fa nbytes

-.Dt REBOOT 2
-.Os
-.Sh NAME
-.Nm reboot
-.Nd reboot system or halt processor
-.Sh LIBRARY
-.Lb libc
-.Sh SYNOPSIS
-.In unistd.h
-.In sys/reboot.h
-.Ft int
-.Fn reboot "int howto"
-.Sh DESCRIPTION
-The
-.Fn reboot
-system call
-reboots the system.
-Only the super-user may reboot a machine on demand.
-However, a reboot is invoked
-automatically in the event of unrecoverable system failures.
-.Pp
-The
-.Fa howto
-argument
-is a mask of options; the system call interface allows the following
-options, defined in the include file
-.In sys/reboot.h ,
-to be passed
-to the new kernel or the new bootstrap and init programs.
-.Bl -tag -width RB_INITNAMEA
-.It Dv RB_AUTOBOOT
-The default, causing the system to reboot in its usual fashion.
-.It Dv RB_ASKNAME
-Interpreted by the bootstrap program itself, causing it to
-prompt on the console as to what file should be booted.
-Normally, the system is booted from the file
-.Dq Ar xx Ns No (0,0)kernel ,
-where
-.Ar xx
-is the default disk name,
-without prompting for the file name.
-.It Dv RB_DFLTROOT
-Use the compiled in root device.
-Normally, the system uses the device from which it was booted
-as the root device if possible.
-(The default behavior is dependent on the ability of the bootstrap program
-to determine the drive from which it was loaded, which is not possible
-on all systems.)
-.It Dv RB_DUMP
-Dump kernel memory before rebooting; see
-.Xr savecore 8
-for more information.
-.It Dv RB_HALT
-the processor is simply halted; no reboot takes place.
-This option should be used with caution.
-.It Dv RB_POWEROFF
-After halting, the shutdown code will do what it can to turn
-off the power.
-This requires hardware support.
-.It Dv RB_INITNAME
-An option allowing the specification of an init program (see
-.Xr init 8 )
-other than
-.Pa /sbin/init
-to be run when the system reboots.
-This switch is not currently available.
-.It Dv RB_KDB
-Load the symbol table and enable a built-in debugger in the system.
-This option will have no useful function if the kernel is not configured
-for debugging.
-Several other options have different meaning if combined
-with this option, although their use may not be possible
-via the
-.Fn reboot
-system call.
-See
-.Xr ddb 4
-for more information.
-.It Dv RB_NOSYNC
-Normally, the disks are sync'd (see
-.Xr sync 8 )
-before the processor is halted or rebooted.
-This option may be useful if file system changes have been made manually
-or if the processor is on fire.
-.It Dv RB_RDONLY
-Initially mount the root file system read-only.
-This is currently the default, and this option has been deprecated.
-.It Dv RB_SINGLE
-Normally, the reboot procedure involves an automatic disk consistency
-check and then multi-user operations.
-.Dv RB_SINGLE
-prevents this, booting the system with a single-user shell
-on the console.
-.Dv RB_SINGLE
-is actually interpreted by the
-.Xr init 8
-program in the newly booted system.
-.El
-.Pp
-When no options are given (i.e.,
-.Dv RB_AUTOBOOT
-is used), the system is
-rebooted from file
-.Dq kernel
-in the root file system of unit 0
-of a disk chosen in a processor specific way.
-An automatic consistency check of the disks is normally performed
-(see
-.Xr fsck 8 ) .
-.Sh RETURN VALUES
-If successful, this call never returns.
-Otherwise, a -1 is returned and an error is returned in the global
-variable
-.Va errno .
-.Sh ERRORS
-.Bl -tag -width Er
-.It Bq Er EPERM
-The caller is not the super-user.
-.El
-.Sh SEE ALSO
-.Xr crash 8 ,
-.Xr halt 8 ,
-.Xr init 8 ,
-.Xr reboot 8 ,

-.Sh HISTORY
-The

-system call appeared in

-.Sh BUGS
-The HP300 implementation supports neither
-.Dv RB_DFLTROOT
-nor
-.Dv RB_KDB .

-.Dt RECV 2
-.Os
-.Sh NAME
-.Nm recv ,
-.Nm recvfrom ,
-.Nm recvmsg
-.Nd receive a message from a socket
-.Sh LIBRARY
-.Lb libc
-.Sh SYNOPSIS
-.In sys/types.h
-.In sys/socket.h
-.Ft ssize_t
-.Fn recv "int s" "void *buf" "size_t len" "int flags"
-.Ft ssize_t
-.Fn recvfrom "int s" "void * restrict buf" "size_t len" "int flags" "struct sockaddr * restrict from" "socklen_t * restrict fromlen"
-.Ft ssize_t
-.Fn recvmsg "int s" "struct msghdr *msg" "int flags"
-.Sh DESCRIPTION
-The
-.Fn recvfrom
-and
-.Fn recvmsg
-system calls
-are used to receive messages from a socket,
-and may be used to receive data on a socket whether or not
-it is connection-oriented.
-.Pp
-If
-.Fa from
-is not a null pointer
-and the socket is not connection-oriented,
-the source address of the message is filled in.
-The
-.Fa fromlen
-argument
-is a value-result argument, initialized to the size of
-the buffer associated with
-.Fa from ,
-and modified on return to indicate the actual size of the
-address stored there.
-.Pp
-The
-.Fn recv
-function is normally used only on a
-.Em connected
-socket (see
-.Xr connect 2 )
-and is identical to
-.Fn recvfrom
-with a
-null pointer passed as its
-.Fa from
-argument.
-.Pp
-All three routines return the length of the message on successful
-completion.
-If a message is too long to fit in the supplied buffer,
-excess bytes may be discarded depending on the type of socket
-the message is received from (see
-.Xr socket 2 ) .
-.Pp
-If no messages are available at the socket, the
-receive call waits for a message to arrive, unless
-the socket is non-blocking (see
-.Xr fcntl 2 )
-in which case the value
-\-1 is returned and the global variable
-.Va errno
-is set to
-.Er EAGAIN .
-The receive calls normally return any data available,
-up to the requested amount,
-rather than waiting for receipt of the full amount requested;
-this behavior is affected by the socket-level options
-.Dv SO_RCVLOWAT
-and
-.Dv SO_RCVTIMEO
-described in
-.Xr getsockopt 2 .
-.Pp
-The
-.Xr select 2
-system call may be used to determine when more data arrives.
-.Pp
-The
-.Fa flags
-argument to a
-.Fn recv
-function is formed by
-.Em or Ap ing
-one or more of the values:
-.Bl -column ".Dv MSG_DONTWAIT" -offset indent
-.It Dv MSG_OOB Ta process out-of-band data
-.It Dv MSG_PEEK Ta peek at incoming message
-.It Dv MSG_WAITALL Ta wait for full request or error
-.It Dv MSG_DONTWAIT Ta do not block
-.El
-.Pp
-The
-.Dv MSG_OOB
-flag requests receipt of out-of-band data
-that would not be received in the normal data stream.
-Some protocols place expedited data at the head of the normal
-data queue, and thus this flag cannot be used with such protocols.
-The
-.Dv MSG_PEEK
-flag causes the receive operation to return data
-from the beginning of the receive queue without removing that
-data from the queue.
-Thus, a subsequent receive call will return the same data.
-The
-.Dv MSG_WAITALL
-flag requests that the operation block until
-the full request is satisfied.
-However, the call may still return less data than requested
-if a signal is caught, an error or disconnect occurs,
-or the next data to be received is of a different type than that returned.
-The
-.Dv MSG_DONTWAIT
-flag requests the call to return when it would block otherwise.
-If no data is available,
-.Va errno
-is set to
-.Er EAGAIN .
-This flag is not available in strict
-.Tn ANSI
-or C99 compilation mode.
-.Pp
-The
-.Fn recvmsg
-system call uses a
-.Fa msghdr
-structure to minimize the number of directly supplied arguments.
-This structure has the following form, as defined in
-.In sys/socket.h :
-.Bd -literal
-struct msghdr {
- void *msg_name; /* optional address */
- socklen_t msg_namelen; /* size of address */
- struct iovec *msg_iov; /* scatter/gather array */
- int msg_iovlen; /* # elements in msg_iov */
- void *msg_control; /* ancillary data, see below */
- socklen_t msg_controllen;/* ancillary data buffer len */
- int msg_flags; /* flags on received message */
-};
-.Ed
-.Pp
-Here
-.Fa msg_name
-and
-.Fa msg_namelen
-specify the destination address if the socket is unconnected;
-.Fa msg_name
-may be given as a null pointer if no names are desired or required.
-The
-.Fa msg_iov
-and
-.Fa msg_iovlen
-arguments
-describe scatter gather locations, as discussed in
-.Xr read 2 .
-The
-.Fa msg_control
-argument,
-which has length
-.Fa msg_controllen ,
-points to a buffer for other protocol control related messages
-or other miscellaneous ancillary data.
-The messages are of the form:
-.Bd -literal
-struct cmsghdr {
- socklen_t cmsg_len; /* data byte count, including hdr */
- int cmsg_level; /* originating protocol */
- int cmsg_type; /* protocol-specific type */
-/* followed by
- u_char cmsg_data[]; */
-};
-.Ed
-.Pp
-As an example, one could use this to learn of changes in the data-stream
-in XNS/SPP, or in ISO, to obtain user-connection-request data by requesting
-a
-.Fn recvmsg
-with no data buffer provided immediately after an
-.Fn accept
-system call.
-.Pp
-Open file descriptors are now passed as ancillary data for
-.Dv AF_UNIX
-domain sockets, with
-.Fa cmsg_level
-set to
-.Dv SOL_SOCKET
-and
-.Fa cmsg_type
-set to
-.Dv SCM_RIGHTS .
-.Pp
-Process credentials can also be passed as ancillary data for
-.Dv AF_UNIX
-domain sockets using a
-.Fa cmsg_type
-of
-.Dv SCM_CREDS .
-In this case,
-.Fa cmsg_data
-should be a structure of type
-.Fa cmsgcred ,
-which is defined in
-.In sys/socket.h
-as follows:
-.Bd -literal
-struct cmsgcred {
- pid_t cmcred_pid; /* PID of sending process */
- uid_t cmcred_uid; /* real UID of sending process */
- uid_t cmcred_euid; /* effective UID of sending process */
- gid_t cmcred_gid; /* real GID of sending process */
- short cmcred_ngroups; /* number or groups */
- gid_t cmcred_groups[CMGROUP_MAX]; /* groups */
-};
-.Ed
-.Pp
-The kernel will fill in the credential information of the sending process
-and deliver it to the receiver.
-.Pp
-The
-.Fa msg_flags
-field is set on return according to the message received.
-.Dv MSG_EOR
-indicates end-of-record;
-the data returned completed a record (generally used with sockets of type
-.Dv SOCK_SEQPACKET ) .
-.Dv MSG_TRUNC
-indicates that
-the trailing portion of a datagram was discarded because the datagram
-was larger than the buffer supplied.
-.Dv MSG_CTRUNC
-indicates that some
-control data were discarded due to lack of space in the buffer
-for ancillary data.
-.Dv MSG_OOB
-is returned to indicate that expedited or out-of-band data were received.
-.Sh RETURN VALUES
-These calls return the number of bytes received, or -1
-if an error occurred.
-.Sh ERRORS
-The calls fail if:
-.Bl -tag -width Er
-.It Bq Er EBADF
-The argument
-.Fa s
-is an invalid descriptor.
-.It Bq Er ECONNRESET
-The remote socket end is forcibly closed.
-.It Bq Er ENOTCONN
-The socket is associated with a connection-oriented protocol
-and has not been connected (see
-.Xr connect 2
-and
-.Xr accept 2 ) .
-.It Bq Er ENOTSOCK
-The argument
-.Fa s
-does not refer to a socket.
-.It Bq Er EMSGSIZE
-The
-.Fn recvmsg
-system call
-was used to receive rights (file descriptors) that were in flight on the
-connection.
-However, the receiving program did not have enough free file
-descriptor slots to accept them.
-In this case the descriptors are
-closed, any pending data can be returned by another call to
-.Fn recvmsg .
-.It Bq Er EAGAIN
-The socket is marked non-blocking, and the receive operation
-would block, or
-a receive timeout had been set,
-and the timeout expired before data were received.
-.It Bq Er EINTR
-The receive was interrupted by delivery of a signal before

-.Fn renameat "int fromfd" "const char *from" "int tofd" "const char *to"
-.Sh DESCRIPTION
-The
-.Fn rename
-system call
-causes the link named
-.Fa from
-to be renamed as
-.Fa to .
-If
-.Fa to
-exists, it is first removed.
-Both
-.Fa from
-and
-.Fa to
-must be of the same type (that is, both directories or both
-non-directories), and must reside on the same file system.
-.Pp
-The
-.Fn rename
-system call
-guarantees that if
-.Fa to
-already exists, an instance of
-.Fa to
-will always exist, even if the system should crash in
-the middle of the operation.
-.Pp
-If the final component of
-.Fa from
-is a symbolic link,
-the symbolic link is renamed,
-not the file or directory to which it points.
-.Pp
-The
-.Fn renameat
-system call is equivalent to
-.Fn rename
-except in the case where either
-.Fa from
-or
-.Fa to
-specifies a relative path.
-If
-.Fa from
-is a relative path, the file to be renamed is located
-relative to the directory associated with the file descriptor
-.Fa fromfd
-instead of the current working directory.
-If the
-.Fa to
-is a relative path, the same happens only relative to the directory associated
-with
-.Fa tofd .
-If the
-.Fn renameat
-is passed the special value
-.Dv AT_FDCWD
-in the
-.Fa fromfd
-or
-.Fa tofd
-parameter, the current working directory is used in the determination
-of the file for the respective path parameter.
-.\".Sh CAVEAT

-.Sh DESCRIPTION
-The
-.Fn revoke
-system call invalidates all current open file descriptors in the system
-for the file named by

-Subsequent operations on any such descriptors
-fail, with the exceptions that a
-.Fn read

-.Pp
-Access to a file may be revoked only by its owner or the super user.
-The

-.Dt RFORK 2
-.Os
-.Sh NAME
-.Nm rfork
-.Nd manipulate process resources
-.Sh LIBRARY
-.Lb libc
-.Sh SYNOPSIS
-.In unistd.h
-.Ft pid_t
-.Fn rfork "int flags"
-.Sh DESCRIPTION
-Forking, vforking or rforking are the only ways new processes are created.
-The
-.Fa flags
-argument to
-.Fn rfork
-selects which resources of the
-invoking process (parent) are shared
-by the new process (child) or initialized to
-their default values.
-The resources include
-the open file descriptor table (which, when shared, permits processes
-to open and close files for other processes),
-and open files.
-The
-.Fa flags
-argument
-is the logical OR of some subset of:
-.Bl -tag -width ".Dv RFLINUXTHPN"
-.It Dv RFPROC
-If set a new process is created; otherwise changes affect the
-current process.
-.It Dv RFNOWAIT
-If set, the child process will be dissociated from the parent.
-Upon
-exit the child will not leave a status for the parent to collect.
-See
-.Xr wait 2 .
-.It Dv RFFDG
-If set, the invoker's file descriptor table (see
-.Xr intro 2 )
-is copied; otherwise the two processes share a
-single table.
-.It Dv RFCFDG
-If set, the new process starts with a clean file descriptor table.
-Is mutually exclusive with
-.Dv RFFDG .
-.It Dv RFTHREAD
-If set, the new process shares file descriptor to process leaders table
-with its parent.
-Only applies when neither
-.Dv RFFDG
-nor
-.Dv RFCFDG
-are set.
-.It Dv RFMEM
-If set, the kernel will force sharing of the entire address space,
-typically by sharing the hardware page table directly.
-The child
-will thus inherit and share all the segments the parent process owns,
-whether they are normally shareable or not.
-The stack segment is
-not split (both the parent and child return on the same stack) and thus
-.Fn rfork
-with the RFMEM flag may not generally be called directly from high level
-languages including C.
-May be set only with
-.Dv RFPROC .
-A helper function is provided to assist with this problem and will cause
-the new process to run on the provided stack.
-See
-.Xr rfork_thread 3
-for information.
-.It Dv RFSIGSHARE
-If set, the kernel will force sharing the sigacts structure between the
-child and the parent.
-.It Dv RFLINUXTHPN
-If set, the kernel will return SIGUSR1 instead of SIGCHILD upon thread
-exit for the child.
-This is intended to mimic certain Linux clone behaviour.
-.El
-.Pp
-File descriptors in a shared file descriptor table are kept
-open until either they are explicitly closed
-or all processes sharing the table exit.
-.Pp
-If
-.Dv RFPROC
-is set, the
-value returned in the parent process
-is the process id
-of the child process; the value returned in the child is zero.
-Without
-.Dv RFPROC ,
-the return value is zero.
-Process id's range from 1 to the maximum integer
-.Ft ( int )
-value.
-The
-.Fn rfork
-system call
-will sleep, if necessary, until required process resources are available.
-.Pp
-The
-.Fn fork
-system call
-can be implemented as a call to
-.Fn rfork "RFFDG | RFPROC"
-but is not for backwards compatibility.
-.Sh RETURN VALUES
-Upon successful completion,
-.Fn rfork
-returns a value
-of 0 to the child process and returns the process ID of the child
-process to the parent process.
-Otherwise, a value of -1 is returned
-to the parent process, no child process is created, and the global
-variable
-.Va errno
-is set to indicate the error.
-.Sh ERRORS
-The
-.Fn rfork
-system call
-will fail and no child process will be created if:
-.Bl -tag -width Er
-.It Bq Er EAGAIN
-The system-imposed limit on the total
-number of processes under execution would be exceeded.
-The limit is given by the
-.Xr sysctl 3
-MIB variable
-.Dv KERN_MAXPROC .
-(The limit is actually ten less than this
-except for the super user).
-.It Bq Er EAGAIN
-The user is not the super user, and

-The limit is given by the
-.Xr sysctl 3

-.Dv KERN_MAXPROCPERUID .
-.It Bq Er EAGAIN
-The user is not the super user, and
-the soft resource limit corresponding to the
-.Fa resource

-.Dv RLIMIT_NOFILE
-would be exceeded (see
-.Xr getrlimit 2 ) .
-.It Bq Er EINVAL
-Both the RFFDG and the RFCFDG flags were specified.

-.Ft int
-.Fn sched_setparam "pid_t pid" "const struct sched_param *param"
-.Ft int
-.Fn sched_getparam "pid_t pid" "struct sched_param *param"
-.Sh DESCRIPTION
-The
-.Fn sched_setparam
-system call sets the scheduling parameters of the process specified by
-.Fa pid
-to the values specified by the
-.Fa sched_param
-structure pointed to by
-.Fa param .
-The value of the
-.Fa sched_priority
-member in the
-.Fa param
-structure must be any integer within the inclusive priority range for
-the current scheduling policy of the process specified by
-.Fa pid .
-Higher numerical values for the priority represent higher priorities.
-.Pp
-In this implementation, if the value of
-.Fa pid
-is negative the system call will fail.
-.Pp
-If a process specified by
-.Fa pid
-exists and if the calling process has permission, the scheduling
-parameters are set for the process whose process ID is equal to
-.Fa pid .
-.Pp
-If
-.Fa pid
-is zero, the scheduling parameters are set for the calling process.
-.Pp
-In this implementation, the policy of when a process can affect
-the scheduling parameters of another process is specified in
-.St -p1003.1b-93
-as a write-style operation.
-.Pp
-The target process, whether it is running or not running, will resume
-execution after all other runnable processes of equal or greater
-priority have been scheduled to run.
-.Pp
-If the priority of the process specified by the
-.Fa pid
-argument is set higher than that of the lowest priority running process
-and if the specified process is ready to run, the process specified by
-the
-.Fa pid
-argument will preempt a lowest priority running process.
-Similarly, if
-the process calling
-.Fn sched_setparam
-sets its own priority lower than that of one or more other nonempty
-process lists, then the process that is the head of the highest priority
-list will also preempt the calling process.
-Thus, in either case, the
-originating process might not receive notification of the completion of
-the requested priority change until the higher priority process has
-executed.
-.Pp
-In this implementation, when the current scheduling policy for the
-process specified by

-.Sh LIBRARY

-.Sh SYNOPSIS
-.In sys/select.h
-.Ft int
-.Fn select "int nfds" "fd_set *readfds" "fd_set *writefds" "fd_set *exceptfds" "struct timeval *timeout"
-.Fn FD_SET fd &fdset
-.Fn FD_CLR fd &fdset
-.Fn FD_ISSET fd &fdset
-.Fn FD_ZERO &fdset
-.Sh DESCRIPTION
-The
-.Fn select
-system call
-examines the I/O descriptor sets whose addresses are passed in
-.Fa readfds ,
-.Fa writefds ,
-and
-.Fa exceptfds
-to see if some of their descriptors
-are ready for reading, are ready for writing, or have an exceptional
-condition pending, respectively.
-The only exceptional condition detectable is out-of-band
-data received on a socket.
-The first
-.Fa nfds
-descriptors are checked in each set;
-i.e., the descriptors from 0 through
-.Fa nfds Ns No -1
-in the descriptor sets are examined.
-On return,
-.Fn select
-replaces the given descriptor sets
-with subsets consisting of those descriptors that are ready
-for the requested operation.
-The
-.Fn select
-system call
-returns the total number of ready descriptors in all the sets.
-.Pp
-The descriptor sets are stored as bit fields in arrays of integers.
-The following macros are provided for manipulating such descriptor sets:
-.Fn FD_ZERO &fdset
-initializes a descriptor set
-.Fa fdset
-to the null set.
-.Fn FD_SET fd &fdset
-includes a particular descriptor
-.Fa fd
-in
-.Fa fdset .
-.Fn FD_CLR fd &fdset
-removes
-.Fa fd
-from
-.Fa fdset .
-.Fn FD_ISSET fd &fdset
-is non-zero if
-.Fa fd
-is a member of
-.Fa fdset ,
-zero otherwise.
-The behavior of these macros is undefined if
-a descriptor value is less than zero or greater than or equal to
-.Dv FD_SETSIZE ,
-which is normally at least equal
-to the maximum number of descriptors supported by the system.
-.Pp
-If
-.Fa timeout
-is not a null pointer, it specifies the maximum interval to wait for the
-selection to complete.
-System activity can lengthen the interval by
-an indeterminate amount.
-.Pp
-If
-.Fa timeout
-is a null pointer, the select blocks indefinitely.
-.Pp
-To effect a poll, the
-.Fa timeout
-argument should not be a null pointer,
-but it should point to a zero-valued timeval structure.
-.Pp
-Any of
-.Fa readfds ,
-.Fa writefds ,
-and
-.Fa exceptfds
-may be given as null pointers if no descriptors are of interest.
-.Sh RETURN VALUES
-The
-.Fn select
-system call
-returns the number of ready descriptors that are contained in
-the descriptor sets,
-or -1 if an error occurred.
-If the time limit expires,
-.Fn select
-returns 0.
-If
-.Fn select
-returns with an error,
-including one due to an interrupted system call,
-the descriptor sets will be unmodified.
-.Sh ERRORS
-An error return from
-.Fn select
-indicates:
-.Bl -tag -width Er
-.It Bq Er EBADF
-One of the descriptor sets specified an invalid descriptor.
-.It Bq Er EFAULT
-One of the arguments
-.Fa readfds , writefds , exceptfds ,
-or
-.Fa timeout
-points to an invalid address.
-.It Bq Er EINTR
-A signal was delivered before the time limit expired and
-before any of the selected events occurred.
-.It Bq Er EINVAL
-The specified time limit is invalid.
-One of its components is
-negative or too large.
-.It Bq Er EINVAL
-The
-.Fa nfds
-argument
-was invalid.

-.Sh NOTES
-The default size of
-.Dv FD_SETSIZE
-is currently 1024.
-In order to accommodate programs which might potentially
-use a larger number of open files with
-.Fn select ,
-it is possible
-to increase this size by having the program define
-.Dv FD_SETSIZE
-before the inclusion of any header which includes
-.In sys/types.h .
-.Pp
-If
-.Fa nfds
-is greater than the number of open files,
-.Fn select
-is not guaranteed to examine the unused file descriptors.
-For historical
-reasons,
-.Fn select
-will always examine the first 256 descriptors.
-.Sh STANDARDS
-The
-.Fn select
-system call and
-.Fn FD_CLR ,
-.Fn FD_ISSET ,
-.Fn FD_SET ,
-and

-may be

-The operation performed depends as follows on the value of
-.Va sem_op :
-.\"
-.\" This section is based on the description of semop() in
-.\" Stevens, _Advanced Programming in the UNIX Environment_,
-.\" and the semop(2) description in The Open Group Unix2 specification.
-.\"
-.Bl -bullet
-.It
-When
-.Va sem_op
-is positive and the process has alter permission,
-the semaphore's value is incremented by
-.Va sem_op Ns 's
-value.
-If
-.Dv SEM_UNDO
-is specified, the semaphore's adjust on exit value is decremented by
-.Va sem_op Ns 's
-value.
-A positive value for
-.Va sem_op
-generally corresponds to a process releasing a resource
-associated with the semaphore.
-.It
-The behavior when
-.Va sem_op
-is negative and the process has alter permission,
-depends on the current value of the semaphore:
-.Bl -bullet
-.It
-If the current value of the semaphore is greater than or equal to
-the absolute value of
-.Va sem_op ,
-then the value is decremented by the absolute value of
-.Va sem_op .
-If
-.Dv SEM_UNDO
-is specified, the semaphore's adjust on exit
-value is incremented by the absolute value of
-.Va sem_op .
-.It
-If the current value of the semaphore is less than the absolute value of
-.Va sem_op ,
-one of the following happens:
-.\" XXX a *second* sublist?
-.Bl -bullet
-.It
-If
-.Dv IPC_NOWAIT
-was specified, then

-.It
-The process receives a signal that is to be caught.
-In this case, the process will resume execution as defined by

-.It
-The semaphore's
-value is greater than or equal to the absolute value of

-When this condition becomes true, the semaphore's value is decremented
-by the absolute value of

-the semaphore's adjust on exit value is incremented by the
-absolute value of
-.Va sem_op .
-.El
-.El
-.El
-.Pp
-A negative value for
-.Va sem_op
-generally means that a process is waiting for a resource to become
-available.
-.It
-When
-.Va sem_op
-is zero and the process has read permission,
-one of the following will occur:
-.Bl -bullet
-.It
-If the current value of the semaphore is equal to zero
-then
-.Fn semop
-can return immediately.
-.It
-If
-.Dv IPC_NOWAIT
-was specified, then

-Otherwise, the calling process is put to sleep until one of the following
-conditions is satisfied:

-For each semaphore a process has in use, the kernel maintains an

-value, as alluded to earlier.
-When a process
-exits, either voluntarily or involuntarily, the adjust on exit value

-.Sh DESCRIPTION
-The
-.Fn send
-function,
-and
-.Fn sendto
-and
-.Fn sendmsg
-system calls
-are used to transmit a message to another socket.
-The
-.Fn send
-function
-may be used only when the socket is in a
-.Em connected
-state, while
-.Fn sendto
-and
-.Fn sendmsg
-may be used at any time.
-.Pp
-The address of the target is given by
-.Fa to
-with
-.Fa tolen
-specifying its size.
-The length of the message is given by
-.Fa len .
-If the message is too long to pass atomically through the
-underlying protocol, the error
-.Er EMSGSIZE
-is returned, and
-the message is not transmitted.
-.Pp
-No indication of failure to deliver is implicit in a
-.Fn send .
-Locally detected errors are indicated by a return value of -1.
-.Pp
-If no messages space is available at the socket to hold
-the message to be transmitted, then
-.Fn send
-normally blocks, unless the socket has been placed in
-non-blocking I/O mode.
-The
-.Xr select 2
-system call may be used to determine when it is possible to
-send more data.
-.Pp
-The
-.Fa flags
-argument may include one or more of the following:
-.Bd -literal
-#define MSG_OOB 0x00001 /* process out-of-band data */
-#define MSG_DONTROUTE 0x00004 /* bypass routing, use direct interface */
-#define MSG_EOR 0x00008 /* data completes record */
-#define MSG_EOF 0x00100 /* data completes transaction */
-#define MSG_NOSIGNAL 0x20000 /* do not generate SIGPIPE on EOF */
-.Ed
-.Pp
-The flag
-.Dv MSG_OOB
-is used to send
-.Dq out-of-band
-data on sockets that support this notion (e.g.\&
-.Dv SOCK_STREAM ) ;
-the underlying protocol must also support
-.Dq out-of-band
-data.
-.Dv MSG_EOR
-is used to indicate a record mark for protocols which support the
-concept.
-.Dv MSG_EOF
-requests that the sender side of a socket be shut down, and that an
-appropriate indication be sent at the end of the specified data;
-this flag is only implemented for
-.Dv SOCK_STREAM
-sockets in the
-.Dv PF_INET
-protocol family.
-.Dv MSG_DONTROUTE
-is usually used only by diagnostic or routing programs.
-.Dv MSG_NOSIGNAL
-is used to prevent
-.Dv SIGPIPE
-generation when writing a socket that
-may be closed.
-.Pp
-See
-.Xr recv 2
-for a description of the
-.Fa msghdr
-structure.
-.Sh RETURN VALUES

-Because

-(see

-.Dt SENDFILE 2
-.Os
-.Sh NAME
-.Nm sendfile
-.Nd send a file to a socket
-.Sh LIBRARY
-.Lb libc
-.Sh SYNOPSIS
-.In sys/types.h
-.In sys/socket.h
-.In sys/uio.h
-.Ft int
-.Fo sendfile
-.Fa "int fd" "int s" "off_t offset" "size_t nbytes"
-.Fa "struct sf_hdtr *hdtr" "off_t *sbytes" "int flags"
-.Fc
-.Sh DESCRIPTION
-The
-.Fn sendfile
-system call
-sends a regular file specified by descriptor
-.Fa fd
-out a stream socket specified by descriptor
-.Fa s .
-.Pp
-The
-.Fa offset
-argument specifies where to begin in the file.
-Should
-.Fa offset
-fall beyond the end of file, the system will return
-success and report 0 bytes sent as described below.
-The
-.Fa nbytes
-argument specifies how many bytes of the file should be sent, with 0 having the special
-meaning of send until the end of file has been reached.
-.Pp
-An optional header and/or trailer can be sent before and after the file data by specifying
-a pointer to a
-.Vt "struct sf_hdtr" ,
-which has the following structure:
-.Pp
-.Bd -literal -offset indent -compact
-struct sf_hdtr {
- struct iovec *headers; /* pointer to header iovecs */
- int hdr_cnt; /* number of header iovecs */
- struct iovec *trailers; /* pointer to trailer iovecs */
- int trl_cnt; /* number of trailer iovecs */
-};
-.Ed
-.Pp
-The
-.Fa headers
-and
-.Fa trailers
-pointers, if
-.Pf non- Dv NULL ,
-point to arrays of
-.Vt "struct iovec"
-structures.
-See the
-.Fn writev
-system call for information on the iovec structure.
-The number of iovecs in these
-arrays is specified by
-.Fa hdr_cnt
-and
-.Fa trl_cnt .
-.Pp
-If
-.Pf non- Dv NULL ,
-the system will write the total number of bytes sent on the socket to the
-variable pointed to by
-.Fa sbytes .
-.Pp
-The
-.Fa flags
-argument is a bitmap of these values:
-.Bl -item -offset indent
-.It
-.Dv SF_NODISKIO .
-This flag causes any
-.Fn sendfile
-call which would block on disk I/O to instead
-return
-.Er EBUSY .
-Busy servers may benefit by transferring requests that would
-block to a separate I/O worker thread.
-.It
-.Dv SF_MNOWAIT .
-Do not wait for some kernel resource to become available,
-in particular,
-.Vt mbuf
-and
-.Vt sf_buf .
-The flag does not make the
-.Fn sendfile
-syscall truly non-blocking, since other resources are still allocated
-in a blocking fashion.
-.It
-.Dv SF_SYNC .
-.Nm
-sleeps until the network stack no longer references the VM pages
-of the file, making subsequent modifications to it safe.
-Please note that this is not a guarantee that the data has actually
-been sent.
-.El
-.Pp
-When using a socket marked for non-blocking I/O,
-.Fn sendfile
-may send fewer bytes than requested.
-In this case, the number of bytes successfully
-written is returned in
-.Fa *sbytes
-(if specified),
-and the error
-.Er EAGAIN
-is returned.
-.Sh IMPLEMENTATION NOTES
-The
-.Fx
-implementation of
-.Fn sendfile
-is "zero-copy", meaning that it has been optimized so that copying of the file data is avoided.
-.Sh TUNING
-On some architectures, this system call internally uses a special
-.Fn sendfile
-buffer
-.Pq Vt "struct sf_buf"
-to handle sending file data to the client.
-If the sending socket is
-blocking, and there are not enough
-.Fn sendfile
-buffers available,
-.Fn sendfile
-will block and report a state of
-.Dq Li sfbufa .
-If the sending socket is non-blocking and there are not enough
-.Fn sendfile
-buffers available, the call will block and wait for the
-necessary buffers to become available before finishing the call.
-.Pp
-The number of
-.Vt sf_buf Ns 's
-allocated should be proportional to the number of nmbclusters used to
-send data to a client via
-.Fn sendfile .
-Tune accordingly to avoid blocking!
-Busy installations that make extensive use of
-.Fn sendfile
-may want to increase these values to be inline with their
-.Va kern.ipc.nmbclusters
-(see
-.Xr tuning 7
-for details).
-.Pp
-The number of
-.Fn sendfile
-buffers available is determined at boot time by either the
-.Va kern.ipc.nsfbufs
-.Xr loader.conf 5
-variable or the
-.Dv NSFBUFS
-kernel configuration tunable.
-The number of
-.Fn sendfile
-buffers scales with
-.Va kern.maxusers .
-The
-.Va kern.ipc.nsfbufsused
-and
-.Va kern.ipc.nsfbufspeak
-read-only
-.Xr sysctl 8
-variables show current and peak
-.Fn sendfile
-buffers usage respectively.
-These values may also be viewed through
-.Nm netstat Fl m .
-.Pp
-If a value of zero is reported for
-.Va kern.ipc.nsfbufs ,
-your architecture does not need to use
-.Fn sendfile
-buffers because their task can be efficiently performed
-by the generic virtual memory structures.
-.Sh RETURN VALUES
-.Rv -std sendfile
-.Sh ERRORS
-.Bl -tag -width Er
-.It Bq Er EAGAIN
-The socket is marked for non-blocking I/O and not all data was sent due to
-the socket buffer being filled.
-If specified, the number of bytes successfully sent will be returned in
-.Fa *sbytes .
-.It Bq Er EBADF
-The
-.Fa fd
-argument
-is not a valid file descriptor.
-.It Bq Er EBADF
-The
-.Fa s
-argument
-is not a valid socket descriptor.
-.It Bq Er EBUSY
-Completing the entire transfer would have required disk I/O, so
-it was aborted.
-Partial data may have been sent.

-is specified.)
-.It Bq Er EFAULT
-An invalid address was specified for an argument.
-.It Bq Er EINTR
-A signal interrupted

-.Sh NAME
-.Nm shm_open , shm_unlink
-.Nd "shared memory object operations"
-.Sh LIBRARY
-.Lb libc
-.Sh SYNOPSIS
-.In sys/types.h
-.In sys/mman.h
-.In fcntl.h
-.Ft int
-.Fn shm_open "const char *path" "int flags" "mode_t mode"
-.Ft int
-.Fn shm_unlink "const char *path"
-.Sh DESCRIPTION
-The
-.Fn shm_open
-system call opens (or optionally creates) a
-.Tn POSIX
-shared memory object named
-.Fa path .
-The
-.Fa flags
-argument contains a subset of the flags used by
-.Xr open 2 .
-An access mode of either
-.Dv O_RDONLY
-or
-.Dv O_RDWR
-must be included in
-.Fa flags .
-The optional flags
-.Dv O_CREAT ,
-.Dv O_EXCL ,
-and
-.Dv O_TRUNC
-may also be specified.
-.Pp
-If
-.Dv O_CREAT
-is specified,
-then a new shared memory object named
-.Fa path
-will be created if it does not exist.
-In this case,
-the shared memory object is created with mode
-.Fa mode
-subject to the process' umask value.
-If both the
-.Dv O_CREAT
-and
-.Dv O_EXCL
-flags are specified and a shared memory object named
-.Fa path
-already exists,
-then
-.Fn shm_open
-will fail with
-.Er EEXIST.
-.Pp
-Newly created objects start off with a size of zero.
-If an existing shared memory object is opened with
-.Dv O_RDWR
-and the
-.Dv O_TRUNC
-flag is specified,
-then the shared memory object will be truncated to a size of zero.
-The size of the object can be adjusted via
-.Xr ftruncate 2
-and queried via
-.Xr fstat 2 .
-.Pp
-The new descriptor is set to close during
-.Xr execve 2
-system calls;
-see
-.Xr close 2
-and
-.Xr fcntl 2 .
-.Pp
-As a FreeBSD extension,
-the constant
-.Dv SHM_ANON
-may be used for the
-.Fa path
-argument to
-.Fn shm_open .
-In this case, an anonymous, unnamed shared memory object is created.
-Since the object has no name,
-it cannot be removed via a subsequent call to
-.Fn shm_unlink .
-Instead,
-the shared memory object will be garbage collected when the last reference to
-the shared memory object is removed.
-The shared memory object may be shared with other processes by sharing the
-file descriptor via
-.Xr fork 2
-or
-.Xr sendmsg 2 .
-Attempting to open an anonymous shared memory object with
-.Dv O_RDONLY
-will fail with
-.Er EINVAL .
-All other flags are ignored.
-.Pp
-The
-.Fn shm_unlink
-system call removes a shared memory object named
-.Fa path .
-.Pp
-.Sh RETURN VALUES
-If successful,
-.Fn shm_open
-returns a non-negative integer,
-and
-.Fn shm_unlink
-returns zero.
-Both functions return -1 on failure, and set
-.Va errno
-to indicate the error.
-.Sh COMPATIBILITY
-The
-.Fa path
-argument does not necessarily represent a pathname (although it does in
-most other implementations).
-Two processes opening the same
-.Fa path
-are guaranteed to access the same shared memory object if and only if
-.Fa path
-begins with a slash
-.Pq Ql \&/
-character.
-.Pp
-Only the
-.Dv O_RDONLY ,
-.Dv O_RDWR ,
-.Dv O_CREAT ,
-.Dv O_EXCL ,
-and
-.Dv O_TRUNC
-flags may be used in portable programs.
-.Pp
-The result of using
-.Xr open 2 ,
-.Xr read 2 ,
-or
-.Xr write 2
-on a shared memory object, or on the descriptor returned by
-.Fn shm_open ,
-is undefined.
-It is also undefined whether the shared memory object itself, or its
-contents, persist across reboots.
-.Pp
-In FreeBSD,
-.Xr read 2
-and
-.Xr write 2
-on a shared memory object will fail with
-.Er EOPNOTSUPP
-and neither shared memory objects nor their contents persist across reboots.
-.Sh ERRORS
-The following errors are defined for
-.Fn shm_open :
-.Bl -tag -width Er
-.It Bq Er EINVAL
-A flag other than

-.Dt SIGACTION 2

-.Sh NAME
-.Nm sigaction
-.Nd software signal facilities
-.Sh LIBRARY

-.Sh SYNOPSIS
-.In signal.h
-.Bd -literal
-struct sigaction {
- void (*sa_handler)(int);
- void (*sa_sigaction)(int, siginfo_t *, void *);

-.Fa "struct sigaction * restrict oact"
-.Fc
-.Sh DESCRIPTION
-The system defines a set of signals that may be delivered to a process.
-Signal delivery resembles the occurrence of a hardware interrupt:
-the signal is normally blocked from further occurrence, the current process
-context is saved, and a new one is built.
-A process may specify a
-.Em handler
-to which a signal is delivered, or specify that a signal is to be
-.Em ignored .
-A process may also specify that a default action is to be taken
-by the system when a signal occurs.
-A signal may also be
-.Em blocked ,
-in which case its delivery is postponed until it is
-.Em unblocked .
-The action to be taken on delivery is determined at the time
-of delivery.
-Normally, signal handlers execute on the current stack
-of the process.
-This may be changed, on a per-handler basis,
-so that signals are taken on a special
-.Em "signal stack" .
-.Pp
-Signal routines normally execute with the signal that caused their
-invocation
-.Em blocked ,
-but other signals may yet occur.
-A global
-.Em "signal mask"
-defines the set of signals currently blocked from delivery
-to a process.
-The signal mask for a process is initialized
-from that of its parent (normally empty).
-It may be changed with a
-.Xr sigprocmask 2
-call, or when a signal is delivered to the process.
-.Pp
-When a signal
-condition arises for a process, the signal is added to a set of
-signals pending for the process.
-If the signal is not currently
-.Em blocked
-by the process then it is delivered to the process.
-Signals may be delivered any time a process enters the operating system
-(e.g., during a system call, page fault or trap, or clock interrupt).
-If multiple signals are ready to be delivered at the same time,
-any signals that could be caused by traps are delivered first.
-Additional signals may be processed at the same time, with each
-appearing to interrupt the handlers for the previous signals
-before their first instructions.
-The set of pending signals is returned by the
-.Xr sigpending 2
-system call.
-When a caught signal
-is delivered, the current state of the process is saved,
-a new signal mask is calculated (as described below),
-and the signal handler is invoked.
-The call to the handler
-is arranged so that if the signal handling routine returns
-normally the process will resume execution in the context
-from before the signal's delivery.
-If the process wishes to resume in a different context, then it
-must arrange to restore the previous context itself.
-.Pp
-When a signal is delivered to a process a new signal mask is
-installed for the duration of the process' signal handler
-(or until a
-.Xr sigprocmask 2
-system call is made).
-This mask is formed by taking the union of the current signal mask set,
-the signal to be delivered, and
-the signal mask associated with the handler to be invoked.
-.Pp
-The
-.Fn sigaction
-system call
-assigns an action for a signal specified by
-.Fa sig .
-If
-.Fa act
-is non-zero, it
-specifies an action
-.Dv ( SIG_DFL ,
-.Dv SIG_IGN ,
-or a handler routine) and mask
-to be used when delivering the specified signal.
-If
-.Fa oact
-is non-zero, the previous handling information for the signal
-is returned to the user.
-.Pp
-The above declaration of
-.Vt "struct sigaction"
-is not literal.
-It is provided only to list the accessible members.
-See
-.In sys/signal.h
-for the actual definition.
-In particular, the storage occupied by sa_handler and sa_sigaction overlaps,
-and an application can not use both simultaneously.
-.Pp
-Once a signal handler is installed, it normally remains installed
-until another
-.Fn sigaction
-system call is made, or an
-.Xr execve 2
-is performed.
-A signal-specific default action may be reset by
-setting
-.Va sa_handler
-to
-.Dv SIG_DFL .
-The defaults are process termination, possibly with core dump;
-no action; stopping the process; or continuing the process.
-See the signal list below for each signal's default action.
-If
-.Va sa_handler
-is
-.Dv SIG_DFL ,
-the default action for the signal is to discard the signal,
-and if a signal is pending,
-the pending signal is discarded even if the signal is masked.
-If
-.Va sa_handler
-is set to
-.Dv SIG_IGN
-current and pending instances
-of the signal are ignored and discarded.
-.Pp
-Options may be specified by setting
-.Va sa_flags .
-The meaning of the various bits is as follows:
-.Bl -tag -offset indent -width SA_RESETHANDXX
-.It Dv SA_NOCLDSTOP
-If this bit is set when installing a catching function
-for the
-.Dv SIGCHLD
-signal,
-the
-.Dv SIGCHLD
-signal will be generated only when a child process exits,
-not when a child process stops.
-.It Dv SA_NOCLDWAIT
-If this bit is set when calling
-.Fn sigaction
-for the
-.Dv SIGCHLD
-signal, the system will not create zombie processes when children of
-the calling process exit.
-If the calling process subsequently issues a
-.Xr wait 2
-(or equivalent), it blocks until all of the calling process's child
-processes terminate, and then returns a value of \-1 with
-.Va errno
-set to
-.Er ECHILD .
-The same effect of avoiding zombie creation can also be achieved by setting
-.Va sa_handler
-for
-.Dv SIGCHLD
-to
-.Dv SIG_IGN .
-.It Dv SA_ONSTACK
-If this bit is set, the system will deliver the signal to the process
-on a
-.Em "signal stack" ,
-specified with
-.Xr sigaltstack 2 .
-.It Dv SA_NODEFER
-If this bit is set, further occurrences of the delivered signal are
-not masked during the execution of the handler.
-.It Dv SA_RESETHAND
-If this bit is set, the handler is reset back to
-.Dv SIG_DFL
-at the moment the signal is delivered.
-.It Dv SA_RESTART
-See paragraph below.
-.It Dv SA_SIGINFO
-If this bit is set, the handler function is assumed to be pointed to by the
-.Va sa_sigaction
-member of
-.Vt "struct sigaction"
-and should match the prototype shown above or as below in
-.Sx EXAMPLES .
-This bit should not be set when assigning
-.Dv SIG_DFL
-or
-.Dv SIG_IGN .
-.El
-.Pp
-If a signal is caught during the system calls listed below,
-the call may be forced to terminate
-with the error
-.Er EINTR ,
-the call may return with a data transfer shorter than requested,
-or the call may be restarted.
-Restart of pending calls is requested
-by setting the
-.Dv SA_RESTART
-bit in
-.Va sa_flags .
-The affected system calls include
-.Xr open 2 ,
-.Xr read 2 ,
-.Xr write 2 ,
-.Xr sendto 2 ,
-.Xr recvfrom 2 ,
-.Xr sendmsg 2
-and
-.Xr recvmsg 2
-on a communications channel or a slow device (such as a terminal,
-but not a regular file)
-and during a
-.Xr wait 2
-or
-.Xr ioctl 2 .
-However, calls that have already committed are not restarted,
-but instead return a partial success (for example, a short read count).
-.Pp
-After a
-.Xr fork 2
-or
-.Xr vfork 2
-all signals, the signal mask, the signal stack,
-and the restart/interrupt flags are inherited by the child.
-.Pp
-The
-.Xr execve 2
-system call reinstates the default
-action for all signals which were caught and
-resets all signals to be caught on the user stack.
-Ignored signals remain ignored;
-the signal mask remains the same;
-signals that restart pending system calls continue to do so.
-.Pp
-The following is a list of all signals

-All functions not in the above lists are considered to be unsafe
-with respect to signals.
-That is to say, the behaviour of such
-functions when called from a signal handler is undefined.
-In general though, signal handlers should do little more than set a
-flag; most other actions are not safe.
-.Pp
-Also, it is good practice to make a copy of the global variable
-.Va errno
-and restore it before returning from the signal handler.
-This protects against the side effect of
-.Va errno
-being set by functions called from inside the signal handler.
-.Sh RETURN VALUES
-.Rv -std sigaction
-.Sh EXAMPLES
-There are three possible prototypes the handler may match:
-.Bl -tag -offset indent -width short
-.It Tn ANSI C :
-.Ft void
-.Fn handler int ;
-.It Traditional BSD style:
-.Ft void
-.Fn handler int "int code" "struct sigcontext *scp" ;
-.It Tn POSIX Dv SA_SIGINFO :
-.Ft void
-.Fn handler int "siginfo_t *info" "ucontext_t *uap" ;
-.El
-.Pp
-The handler function should match the
-.Dv SA_SIGINFO
-prototype if the
-.Dv SA_SIGINFO
-bit is set in
-.Va sa_flags .
-It then should be pointed to by the
-.Va sa_sigaction
-member of
-.Vt "struct sigaction" .
-Note that you should not assign
-.Dv SIG_DFL
-or
-.Dv SIG_IGN
-this way.
-.Pp
-If the
-.Dv SA_SIGINFO
-flag is not set, the handler function should match
-either the
-.Tn ANSI C
-or traditional
-.Bx
-prototype and be pointed to by
-the
-.Va sa_handler
-member of
-.Vt "struct sigaction" .
-In practice,
-.Fx
-always sends the three arguments of the latter and since the
-.Tn ANSI C
-prototype is a subset, both will work.
-The
-.Va sa_handler
-member declaration in
-.Fx
-include files is that of
-.Tn ANSI C
-(as required by
-.Tn POSIX ) ,
-so a function pointer of a
-.Bx Ns -style
-function needs to be casted to
-compile without warning.
-The traditional
-.Bx
-style is not portable and since its capabilities
-are a full subset of a
-.Dv SA_SIGINFO
-handler,
-its use is deprecated.
-.Pp
-The
-.Fa sig
-argument is the signal number, one of the
-.Dv SIG...
-values from
-.In signal.h .
-.Pp
-The
-.Fa code
-argument of the
-.Bx Ns -style
-handler and the
-.Va si_code
-member of the
-.Fa info
-argument to a
-.Dv SA_SIGINFO
-handler contain a numeric code explaining the
-cause of the signal, usually one of the
-.Dv SI_...
-values from
-.In sys/signal.h
-or codes specific to a signal, i.e., one of the
-.Dv FPE_...
-values for
-.Dv SIGFPE .
-.Pp
-The
-.Fa scp
-argument to a
-.Bx Ns -style
-handler points to an instance of
-.Vt "struct sigcontext" .
-.Pp
-The
-.Fa uap
-argument to a
-.Tn POSIX
-.Dv SA_SIGINFO
-handler points to an instance of
-ucontext_t.
-.Sh ERRORS
-The
-.Fn sigaction
-system call
-will fail and no new signal handler will be installed if one
-of the following occurs:
-.Bl -tag -width Er
-.It Bq Er EFAULT
-Either
-.Fa act

-.Os
-.Sh NAME
-.Nm sigaltstack
-.Nd set and/or get signal stack context
-.Sh LIBRARY
-.Lb libc
-.Sh SYNOPSIS
-.In signal.h
-.Bd -literal
-typedef struct {
- char *ss_sp;
- size_t ss_size;
- int ss_flags;
-} stack_t;
-.Ed
-.Ft int
-.Fn sigaltstack "const stack_t * restrict ss" "stack_t * restrict oss"
-.Sh DESCRIPTION
-The
-.Fn sigaltstack
-system call
-allows defining an alternate stack on which signals
-are to be processed for the current thread.
-If
-.Fa ss
-is non-zero,
-it specifies a pointer to and the size of a
-.Em "signal stack"
-on which to deliver signals.
-When a signal's action indicates its handler
-should execute on the signal stack (specified with a
-.Xr sigaction 2
-system call), the system checks to see
-if the thread is currently executing on that stack.
-If the thread is not currently executing on the signal stack,
-the system arranges a switch to the signal stack for the
-duration of the signal handler's execution.
-.Pp
-An active stack cannot be modified.
-.Pp
-If
-.Dv SS_DISABLE
-is set in
-.Fa ss_flags ,
-.Fa ss_sp
-and
-.Fa ss_size
-are ignored and the signal stack will be disabled.
-A disabled stack will cause all signals to be
-taken on the regular user stack.
-If the stack is later re-enabled then all signals that were specified
-to be processed on an alternate stack will resume doing so.
-.Pp
-If
-.Fa oss
-is non-zero, the current signal stack state is returned.
-The
-.Fa ss_flags
-field will contain the value
-.Dv SS_ONSTACK
-if the thread is currently on a signal stack and
-.Dv SS_DISABLE
-if the signal stack is currently disabled.
-.Sh NOTES
-The value
-.Dv SIGSTKSZ
-is defined to be the number of bytes/chars that would be used to cover
-the usual case when allocating an alternate stack area.
-The following code fragment is typically used to allocate an alternate stack.
-.Bd -literal -offset indent
-if ((sigstk.ss_sp = malloc(SIGSTKSZ)) == NULL)
- /* error return */
-sigstk.ss_size = SIGSTKSZ;
-sigstk.ss_flags = 0;
-if (sigaltstack(&sigstk, NULL) < 0)
- perror("sigaltstack");
-.Ed
-An alternative approach is provided for programs with signal handlers
-that require a specific amount of stack space other than the default size.
-The value
-.Dv MINSIGSTKSZ
-is defined to be the number of bytes/chars that is required by
-the operating system to implement the alternate stack feature.
-In computing an alternate stack size,
-programs should add
-.Dv MINSIGSTKSZ
-to their stack requirements to allow for the operating system overhead.
-.Pp
-Signal stacks are automatically adjusted for the direction of stack
-growth and alignment requirements.
-Signal stacks may or may not be protected by the hardware and
-are not ``grown'' automatically as is done for the normal stack.
-If the stack overflows and this space is not protected
-unpredictable results may occur.
-.Sh RETURN VALUES
-.Rv -std sigaltstack
-.Sh ERRORS
-The
-.Fn sigaltstack
-system call
-will fail and the signal stack context will remain unchanged
-if one of the following occurs.
-.Bl -tag -width Er

-Either
-.Fa ss

-.Sh DESCRIPTION
-The
-.Fn sigwait
-system call selects a set of signals, specified by
-.Fa set .
-If none of the selected signals are pending,
-.Fn sigwait
-waits until one or more of the selected signals has been generated.
-Then
-.Fn sigwait
-atomically clears one of the selected signals from the set of pending signals
-for the process and sets the location pointed to by
-.Fa sig
-to the signal number that was cleared.
-.Pp
-The signals specified by

-should be blocked at the time of the call to
-.Fn sigwait .
-.Pp
-If more than one thread is using
-.Fn sigwait
-to wait for the same signal, no more than one of these threads will return from
-.Fn sigwait
-with the signal number.
-If more than a single thread is blocked in
-.Fn sigwait
-for a signal when that signal is generated for the process, it is unspecified
-which of the waiting threads returns from
-.Fn sigwait .
-If the signal is generated for a specific thread, as by
-.Fn pthread_kill ,
-only that thread will return.
-.Pp
-Should any of the multiple pending signals in the range

-be

-The selection order between realtime
-and non-realtime signals, or between multiple pending non-realtime signals,

-.Sh RETURN VALUES
-If successful,

-The

-are pending,
-.Fn sigtimedwait
-waits for the time interval specified in the

-If the
-.Vt timespec
-structure pointed to by

-returns immediately with an error.
-If
-.Fa timeout
-is the
-.Dv NULL
-pointer, the behavior is unspecified.
-.Dv CLOCK_MONOTONIC
-clock is used to measure the time interval specified by the
-.Fa timeout
-argument.
-.Pp
-The
-.Fn sigwaitinfo
-system call selects the pending signal from the set specified by
-.Fa set .
-Should any of multiple pending signals in the range
-.Dv SIGRTMIN
-to
-.Dv SIGRTMAX
-be selected, it shall be the lowest numbered one.
-The
-selection order between realtime and non-realtime signals, or
-between multiple pending non-realtime signals, is unspecified.
-If no signal in
-.Fa set
-is pending at the time of the call, the calling thread
-is suspended until one or more signals in
-.Fa set
-become pending or until it is interrupted by an unblocked, caught signal.
-.Pp
-The
-.Fn sigwaitinfo
-system call is equivalent to the
-.Fn sigwait
-system call if the
-.Fa info
-argument is
-.Dv NULL .
-If the
-.Fa info
-argument is

-If any value is queued to the selected signal, the first such queued
-value is dequeued and, if the info argument is
-.Pf non- Dv NULL ,
-the value is stored in the
-.Va si_value
-member of
-.Fa info .
-The system resource used to queue the signal
-is released and returned to the system for other use.
-If no value is queued,
-the content of the
-.Va si_value
-member is zero-valued.
-If no further signals are
-queued for the selected signal, the pending indication for that signal
-is reset.
-.Sh RETURN VALUES
-Upon successful completion (that is, one of the signals specified by
-.Fa set
-is pending or is generated)
-.Fn sigwaitinfo
-and

-return the selected signal number.
-Otherwise, the functions return a value of \-1

-two-way connection based byte streams.
-An out-of-band data transmission mechanism may be supported.
-A
-.Dv SOCK_DGRAM
-socket supports
-datagrams (connectionless, unreliable messages of
-a fixed (typically small) maximum length).
-A
-.Dv SOCK_SEQPACKET
-socket may provide a sequenced, reliable,
-two-way connection-based data transmission path for datagrams
-of fixed maximum length; a consumer may be required to read
-an entire packet with each read system call.
-This facility is protocol specific, and presently unimplemented.
-.Dv SOCK_RAW
-sockets provide access to internal network protocols and interfaces.
-The types
-.Dv SOCK_RAW ,
-which is available only to the super-user, and
-.Dv SOCK_RDM ,
-which is planned,
-but not yet implemented, are not described here.
-.Pp
-The
-.Fa protocol
-argument
-specifies a particular protocol to be used with the socket.
-Normally only a single protocol exists to support a particular
-socket type within a given protocol family.
-However, it is possible
-that many protocols may exist, in which case a particular protocol
-must be specified in this manner.
-The protocol number to use is
-particular to the
-.Dq "communication domain"
-in which communication
-is to take place; see
-.Xr protocols 5 .
-.Pp
-The
-.Fa protocol
-argument may be set to zero (0) to request the default
-implementation of a socket type for the protocol, if any.
-.Pp
-Sockets of type
-.Dv SOCK_STREAM
-are full-duplex byte streams, similar
-to pipes.
-A stream socket must be in a
-.Em connected
-state before any data may be sent or received
-on it.
-A connection to another socket is created with a
-.Xr connect 2
-system call.
-Once connected, data may be transferred using
-.Xr read 2
-and
-.Xr write 2
-calls or some variant of the
-.Xr send 2
-and
-.Xr recv 2
-functions.
-(Some protocol families, such as the Internet family,
-support the notion of an
-.Dq implied connect ,
-which permits data to be sent piggybacked onto a connect operation by
-using the
-.Xr sendto 2
-system call.)
-When a session has been completed a
-.Xr close 2
-may be performed.
-Out-of-band data may also be transmitted as described in
-.Xr send 2
-and received as described in
-.Xr recv 2 .
-.Pp
-The communications protocols used to implement a
-.Dv SOCK_STREAM
-ensure that data
-is not lost or duplicated.
-If a piece of data for which the
-peer protocol has buffer space cannot be successfully transmitted
-within a reasonable length of time, then
-the connection is considered broken and calls
-will indicate an error with
--1 returns and with
-.Er ETIMEDOUT
-as the specific code
-in the global variable
-.Va errno .
-The protocols optionally keep sockets
-.Dq warm
-by forcing transmissions
-roughly every minute in the absence of other activity.
-An error is then indicated if no response can be
-elicited on an otherwise
-idle connection for an extended period (e.g.\& 5 minutes).
-By default, a
-.Dv SIGPIPE
-signal is raised if a process sends
-on a broken stream, but this behavior may be inhibited via
-.Xr setsockopt 2 .
-.Pp
-.Dv SOCK_SEQPACKET
-sockets employ the same system calls
-as
-.Dv SOCK_STREAM
-sockets.
-The only difference
-is that
-.Xr read 2
-calls will return only the amount of data requested,
-and any remaining in the arriving packet will be discarded.
-.Pp
-.Dv SOCK_DGRAM
-and
-.Dv SOCK_RAW
-sockets allow sending of datagrams to correspondents
-named in
-.Xr send 2
-calls.
-Datagrams are generally received with
-.Xr recvfrom 2 ,
-which returns the next datagram with its return address.
-.Pp
-An
-.Xr fcntl 2
-system call can be used to specify a process group to receive
-a
-.Dv SIGURG
-signal when the out-of-band data arrives.
-It may also enable non-blocking I/O
-and asynchronous notification of I/O events
-via
-.Dv SIGIO .
-.Pp
-The operation of sockets is controlled by socket level
-.Em options .
-These options are defined in the file
-.In sys/socket.h .
-The
-.Xr setsockopt 2
-and
-.Xr getsockopt 2
-system calls are used to set and get options, respectively.
-.Sh RETURN VALUES
-A -1 is returned if an error occurs, otherwise the return
-value is a descriptor referencing the socket.
-.Sh ERRORS
-The
-.Fn socket
-system call fails if:
-.Bl -tag -width Er

-.Ft int
-.Fn stat "const char *path" "struct stat *sb"
-.Ft int
-.Fn lstat "const char *path" "struct stat *sb"
-.Ft int
-.Fn fstat "int fd" "struct stat *sb"
-.Ft int
-.Fn fstatat "int fd" "const char *path" "struct stat *buf" "int flag"
-.Sh DESCRIPTION
-The
-.Fn stat
-system call obtains information about the file pointed to by
-.Fa path .
-Read, write or execute
-permission of the named file is not required, but all directories
-listed in the path name leading to the file must be searchable.
-.Pp
-The
-.Fn lstat
-system call is like
-.Fn stat
-except in the case where the named file is a symbolic link,
-in which case
-.Fn lstat
-returns information about the link,
-while
-.Fn stat
-returns information about the file the link references.
-.Pp
-The
-.Fn fstat
-system call obtains the same information about an open file
-known by the file descriptor
-.Fa fd .
-.Pp
-The
-.Fn fstatat
-system call is equivalent to
-.Fn stat
-and
-.Fn lstat
-except in the case where the
-.Fa path
-specifies a relative path.
-In this case the status is retrieved from a file relative to
-the directory associated with the file descriptor
-.Fa fd
-instead of the current working directory.
-.Pp
-The values for the
-.Fa flag
-are constructed by a bitwise-inclusive OR of flags from the following list,
-defined in
-.In fcntl.h :
-.Bl -tag -width indent
-.It Dv AT_SYMLINK_NOFOLLOW
-If
-.Fa path
-names a symbolic link, the status of the symbolic link is returned.
-.El
-.Pp
-If
-.Fn fstatat
-is passed the special value
-.Dv AT_FDCWD
-in the
-.Fa fd
-parameter, the current working directory is used and the behavior is
-identical to a call to
-.Fn stat
-or
-.Fn lstat
-respectively, depending on whether or not the
-.Dv AT_SYMLINK_NOFOLLOW
-bit is set in
-.Fa flag .
-.Pp
-The
-.Fa sb
-argument is a pointer to a
-.Vt stat
-structure
-as defined by
-.In sys/stat.h
-and into which information is placed concerning the file.
-.Pp
-The fields of
-.Vt "struct stat"
-related to the file system are as follows:
-.Bl -tag -width ".Va st_nlink"
-.It Va st_dev
-The numeric ID of the device containing the file.
-.It Va st_ino
-The file's inode number.
-.It Va st_nlink
-The number of hard links to the file.
-.El
-.Pp
-The
-.Va st_dev
-and
-.Va st_ino
-fields together identify the file uniquely within the system.
-.Pp
-The time-related fields of
-.Vt "struct stat"
-are as follows:
-.Bl -tag -width ".Va st_birthtim"
-.It Va st_atim
-Time when file data last accessed.
-Changed by the
-.Xr mknod 2 ,

-system calls.
-.It Va st_birthtim
-Time when the inode was created.

-The size-related fields of the
-.Vt "struct stat"
-are as follows:
-.Bl -tag -width ".Va st_blksize"
-.It Va st_size
-The file size in bytes.
-.It Va st_blksize
-The optimal I/O block size for the file.
-.It Va st_blocks
-The actual number of blocks allocated for the file in 512-byte units.
-As short symbolic links are stored in the inode, this number may

-.Fc
-.Sh DESCRIPTION
-The
-.Fn timer_create
-system call creates a per-process timer using the specified clock,
-.Fa clock_id ,
-as the timing base.
-The
-.Fn timer_create
-system call returns, in the location referenced by
-.Fa timerid ,
-a timer ID of type
-.Vt timer_t
-used to identify the timer in timer requests.
-This timer ID is unique within the calling process until the timer is deleted.
-The particular clock,
-.Fa clock_id ,
-is defined in
-.In time.h .
-The timer whose ID is returned is in a disarmed state upon return from
-.Fn timer_create .
-.Pp
-The
-.Fa evp
-argument, if
-.Pf non- Dv NULL ,
-points to a
-.Vt sigevent
-structure.
-This structure,
-allocated by the application, defines the asynchronous notification to occur
-when the timer expires.
-If the
-.Fa evp
-argument is
-.Dv NULL ,
-the effect is as if the
-.Fa evp
-argument pointed to a

-a thread stack address specified by a call to
-.Fn pthread_attr_setstack
-or
-.Fn pthread_attr_setstackaddr ,
-the results are unspecified if the signal is generated more than once.
-.Sh RETURN VALUES
-If the call succeeds,
-.Fn timer_create
-returns zero and updates the location referenced by

-which can be passed to the per-process timer calls.
-If an error
-occurs, the system call returns a value of \-1
-and the global variable

-.Sh DESCRIPTION
-The
-.Fn timer_gettime
-system call stores the amount of time until the specified timer,
-.Fa timerid ,
-expires and the reload value of the timer into the space pointed to by the
-.Fa value
-argument.
-The
-.Va it_value
-member of this structure contains the amount of time
-before the timer expires, or zero if the timer is disarmed.
-This value is
-returned as the interval until timer expiration, even if the timer was armed
-with absolute time.
-The
-.Va it_interval
-member of
-.Fa value
-contains the reload
-value last set by
-.Fn timer_settime .
-.Pp
-The
-.Fn timer_settime
-system call sets the time until the next expiration of the timer specified
-by
-.Fa timerid
-from the
-.Va it_value
-member of the
-.Fa value
-argument and arms the timer if the
-.Va it_value
-member of
-.Fa value
-is non-zero.
-If the specified timer was already
-armed when
-.Fn timer_settime
-is called, this call resets the time until next expiration to the value
-specified.
-If the
-.Va it_value
-member of
-.Fa value
-is zero, the timer is disarmed.
-If the timer is disarmed, then pending signal is removed.
-.Pp
-If the flag
-.Dv TIMER_ABSTIME
-is not set in the argument
-.Fa flags ,
-.Fn timer_settime
-behaves as if the time until next expiration is set to
-be equal to the interval specified by the
-.Va it_value
-member of
-.Fa value .
-That is,
-the timer expires in
-.Va it_value
-nanoseconds from when the call is made.
-If the flag
-.Dv TIMER_ABSTIME
-is set in the argument
-.Fa flags ,
-.Fn timer_settime
-behaves as if the time until next expiration is set to be equal to the
-difference between the absolute time specified by the it_value member of
-value and the current value of the clock associated with
-.Fa timerid .
-That is, the timer expires when the clock reaches the value specified by the
-.Va it_value
-member of
-.Fa value .
-If the specified time has already passed, the
-system call succeeds and the expiration notification is made.
-.Pp
-The reload value of the timer is set to the value specified by the
-.Va it_interval
-member of
-.Fa value .
-When a timer is armed with a non-zero
-.Va it_interval ,
-a periodic
-(or repetitive) timer is specified.
-.Pp
-Time values that are between two consecutive non-negative integer multiples of
-the resolution of the specified timer are rounded up to the larger multiple of
-the resolution.
-Quantization error will not cause the timer to expire earlier
-than the rounded time value.
-.Pp
-If the argument
-.Fa ovalue
-is not
-.Dv NULL ,
-the
-.Fn timer_settime
-system call stores, in the location referenced by
-.Fa ovalue ,
-a value representing
-the previous amount of time before the timer would have expired, or zero if the
-timer was disarmed, together with the previous timer reload value.
-Timers do not
-expire before their scheduled time.
-.Pp
-Only a single signal is queued to the process for a given timer at any point in
-time.
-When a timer for which a signal is still pending expires, no signal is
-queued, and a timer overrun will occur.
-When a timer expiration signal is
-accepted by a process, the
-.Fn timer_getoverrun
-system call returns the timer expiration overrun count for the specified timer.
-The overrun count returned contains the number of extra timer expirations that
-occurred between the time the signal was generated (queued) and when it was
-accepted, up to but not including an maximum of
-.Brq Dv DELAYTIMER_MAX .
-If the number of
-such extra expirations is greater than or equal to
-.Brq Dv DELAYTIMER_MAX ,
-then the overrun count is set to
-.Brq Dv DELAYTIMER_MAX .
-The value returned by
-.Fn timer_getoverrun
-applies to the most recent expiration signal acceptance for the timer.
-If no
-expiration signal has been delivered for the timer, the return value of
-.Fn timer_getoverrun
-is unspecified.
-.Sh RETURN VALUES
-If the
-.Fn timer_getoverrun
-system call succeeds, it returns the timer expiration overrun count as explained
-above.
-Otherwise the value \-1 is returned, and the global variable

-.Sh DESCRIPTION
-The
-.Fn unlink
-system call
-removes the link named by
-.Fa path
-from its directory and decrements the link count of the
-file which was referenced by the link.
-If that decrement reduces the link count of the file
-to zero,
-and no process has the file open, then
-all resources associated with the file are reclaimed.
-If one or more process have the file open when the last link is removed,
-the link is removed, but the removal of the file is delayed until
-all references to it have been closed.
-The
-.Fa path
-argument
-may not be a directory.

-The

-system call is equivalent to

-except in the case where

-specifies a relative path.
-In this case the directory entry to be removed is determined
-relative to the directory associated with the file descriptor

-.Pp
-If

-is passed the special value
-.Dv AT_FDCWD
-in the

-.Sh DESCRIPTION
-The access and modification times of the file named by
-.Fa path
-or referenced by
-.Fa fd
-are changed as specified by the argument
-.Fa times .
-.Pp
-If
-.Fa times
-is
-.Dv NULL ,
-the access and modification times are set to the current time.
-The caller must be the owner of the file, have permission to
-write the file, or be the super-user.
-.Pp
-If
-.Fa times
-is
-.No non- Ns Dv NULL ,
-it is assumed to point to an array of two timeval structures.
-The access time is set to the value of the first element, and the
-modification time is set to the value of the second element.
-For file systems that support file birth (creation) times (such as
-.Dv UFS2 ) ,
-the birth time will be set to the value of the second element
-if the second element is older than the currently set birth time.
-To set both a birth time and a modification time,
-two calls are required; the first to set the birth time
-and the second to set the (presumably newer) modification time.
-Ideally a new system call will be added that allows the setting
-of all three times at once.
-The caller must be the owner of the file or be the super-user.
-.Pp
-In either case, the inode-change-time of the file is set to the current
-time.
-.Pp
-The
-.Fn lutimes
-system call
-is like
-.Fn utimes
-except in the case where the named file is a symbolic link,
-in which case
-.Fn lutimes
-changes the access and modification times of the link,
-while
-.Fn utimes
-changes the times of the file the link references.
-.Pp
-The
-.Fn futimesat
-system call is equivalent to
-.Fn utimes

-specifies a relative path.
-In this case the access and modification time
-is set to that of a file relative to the directory associated with the file

-.Sh NAME
-.Nm uuidgen
-.Nd generate universally unique identifiers
-.Sh LIBRARY
-.Lb libc
-.Sh SYNOPSIS
-.In sys/uuid.h
-.Ft int
-.Fn uuidgen "struct uuid *store" "int count"
-.Sh DESCRIPTION
-The
-.Fn uuidgen
-system call generates
-.Fa count
-universally unique identifiers (UUIDs) and writes them to the buffer
-pointed to by
-.Fa store .
-The identifiers are generated according to the syntax and semantics of the
-DCE version 1 variant of universally unique identifiers.
-See below for a more in-depth description of the identifiers.
-When no IEEE 802
-address is available for the node field, a random multicast address is
-generated for each invocation of the system call.
-According to the algorithm of generating time-based UUIDs, this will also
-force a new random clock sequence, thereby increasing the likelihood for
-the identifier to be unique.
-.Pp
-When multiple identifiers are to be generated, the
-.Fn uuidgen
-system call will generate a set of identifiers that is dense in such a way
-that there is no identifier that is larger than the smallest identifier in the
-set and smaller than the largest identifier in the set and that is not already
-in the set.
-.Pp
-Universally unique identifiers, also known as globally unique identifiers
-(GUIDs), have a binary representation of 128-bits.
-The grouping and meaning of these bits is described by the following
-structure and its description of the fields that follow it:
-.Bd -literal
-struct uuid {
- uint32_t time_low;
- uint16_t time_mid;
- uint16_t time_hi_and_version;
- uint8_t clock_seq_hi_and_reserved;
- uint8_t clock_seq_low;
- uint8_t node[_UUID_NODE_LEN];
-};
-.Ed
-.Bl -tag -width ".Va clock_seq_hi_and_reserved"
-.It Va time_low
-The least significant 32 bits of a 60-bit timestamp.
-This field is stored in the native byte-order.
-.It Va time_mid
-The least significant 16 bits of the most significant 28 bits of the 60-bit
-timestamp.
-This field is stored in the native byte-order.
-.It Va time_hi_and_version
-The most significant 12 bits of the 60-bit timestamp multiplexed with a 4-bit
-version number.
-The version number is stored in the most significant 4 bits of the 16-bit
-field.
-This field is stored in the native byte-order.
-.It Va clock_seq_hi_and_reserved
-The most significant 6 bits of a 14-bit sequence number multiplexed with a
-2-bit variant value.
-Note that the width of the variant value is determined by the variant itself.
-Identifiers generated by the
-.Fn uuidgen
-system call have variant value 10b.
-the variant value is stored in the most significant bits of the field.
-.It Va clock_seq_low
-The least significant 8 bits of a 14-bit sequence number.
-.It Va node
-The 6-byte IEEE 802 (MAC) address of one of the interfaces of the node.
-If no such interface exists, a random multi-cast address is used instead.
-.El
-.Pp
-The binary representation is sensitive to byte ordering.
-Any multi-byte field is to be stored in the local or native byte-order and
-identifiers must be converted when transmitted to hosts that do not agree
-on the byte-order.
-The specification does not however document what this means in concrete
-terms and is otherwise beyond the scope of this system call.
-.Sh RETURN VALUES
-.Rv -std
-.Sh ERRORS
-The
-.Fn uuidgen
-system call can fail with:
-.Bl -tag -width Er
-.It Bq Er EFAULT
-The buffer pointed to by
-.Fa store
-could not be written to for any or all identifiers.
-.It Bq Er EINVAL

-.El
-.Sh SEE ALSO

-.Sh LIBRARY
-.Lb libc
-.Sh SYNOPSIS
-.In unistd.h
-.Ft pid_t
-.Fn vfork void
-.Sh DESCRIPTION
-The
-.Fn vfork
-system call
-can be used to create new processes without fully copying the address
-space of the old process, which is horrendously inefficient in a paged
-environment.
-It is useful when the purpose of
-.Xr fork 2
-would have been to create a new system context for an
-.Xr execve 2 .
-The
-.Fn vfork
-system call
-differs from
-.Xr fork 2
-in that the child borrows the parent's memory and thread of
-control until a call to
-.Xr execve 2
-or an exit (either by a call to
-.Xr _exit 2
-or abnormally).
-The parent process is suspended while the child is using its resources.
-.Pp
-The
-.Fn vfork
-system call
-returns 0 in the child's context and (later) the pid of the child in
-the parent's context.
-.Pp
-The
-.Fn vfork
-system call
-can normally be used just like
-.Xr fork 2 .
-It does not work, however, to return while running in the child's context
-from the procedure that called
-.Fn vfork
-since the eventual return from
-.Fn vfork
-would then return to a no longer existent stack frame.
-Be careful, also, to call
-.Xr _exit 2
-rather than
-.Xr exit 3
-if you cannot
-.Xr execve 2 ,
-since
-.Xr exit 3
-will flush and close standard I/O channels, and thereby mess up the
-parent processes standard I/O data structures.
-(Even with
-.Xr fork 2
-it is wrong to call
-.Xr exit 3
-since buffered data would then be flushed twice.)
-.Sh RETURN VALUES

-.Xr fork 2 .

-are never sent

-or

-.Sh DESCRIPTION
-The
-.Fn wait
-function suspends execution of its calling process until
-.Fa status
-information is available for a terminated child process,
-or a signal is received.
-On return from a successful
-.Fn wait
-call,
-the
-.Fa status
-area contains termination information about the process that exited
-as defined below.
-.Pp
-The
-.Fn wait4
-system call provides a more general interface for programs
-that need to wait for certain child processes,
-that need resource utilization statistics accumulated by child processes,
-or that require options.
-The other wait functions are implemented using
-.Fn wait4 .
-.Pp
-The
-.Fa wpid
-argument specifies the set of child processes for which to wait.
-If
-.Fa wpid
-is -1, the call waits for any child process.
-If
-.Fa wpid
-is 0,
-the call waits for any child process in the process group of the caller.
-If
-.Fa wpid
-is greater than zero, the call waits for the process with process id
-.Fa wpid .
-If
-.Fa wpid
-is less than -1, the call waits for any process whose process group id
-equals the absolute value of
-.Fa wpid .
-.Pp
-The
-.Fa status
-argument is defined below.
-.Pp
-The
-.Fa options
-argument contains the bitwise OR of any of the following options.
-The
-.Dv WCONTINUED
-option indicates that children of the current process that
-have continued from a job control stop, by receiving a
-.Dv SIGCONT
-signal, should also have their status reported.
-The
-.Dv WNOHANG
-option
-is used to indicate that the call should not block if
-there are no processes that wish to report status.
-If the
-.Dv WUNTRACED
-option is set,
-children of the current process that are stopped
-due to a
-.Dv SIGTTIN , SIGTTOU , SIGTSTP ,
-or
-.Dv SIGSTOP
-signal also have their status reported.
-The
-.Dv WSTOPPED
-option is an alias for
-.Dv WUNTRACED .
-The
-.Dv WNOWAIT
-option keeps the process whose status is returned in a waitable state.
-The process may be waited for again after this call completes.
-.Pp
-If
-.Fa rusage
-is non-zero, a summary of the resources used by the terminated
-process and all its
-children is returned (this information is currently not available
-for stopped or continued processes).
-.Pp
-When the
-.Dv WNOHANG
-option is specified and no processes
-wish to report status,
-.Fn wait4
-returns a
-process id
-of 0.
-.Pp
-The
-.Fn waitpid
-function is identical to
-.Fn wait4
-with an
-.Fa rusage
-value of zero.
-The older
-.Fn wait3
-call is the same as
-.Fn wait4
-with a
-.Fa wpid
-value of -1.
-.Pp
-The following macros may be used to test the manner of exit of the process.
-One of the first three macros will evaluate to a non-zero (true) value:
-.Bl -tag -width Ds
-.It Fn WIFCONTINUED status
-True if the process has not terminated, and
-has continued after a job control stop.
-This macro can be true only if the wait call specified the
-.Dv WCONTINUED
-option).
-.It Fn WIFEXITED status
-True if the process terminated normally by a call to
-.Xr _exit 2
-or
-.Xr exit 3 .
-.It Fn WIFSIGNALED status
-True if the process terminated due to receipt of a signal.
-.It Fn WIFSTOPPED status
-True if the process has not terminated, but has stopped and can be restarted.
-This macro can be true only if the wait call specified the
-.Dv WUNTRACED
-option
-or if the child process is being traced (see
-.Xr ptrace 2 ) .
-.El
-.Pp
-Depending on the values of those macros, the following macros
-produce the remaining status information about the child process:
-.Bl -tag -width Ds
-.It Fn WEXITSTATUS status
-If
-.Fn WIFEXITED status
-is true, evaluates to the low-order 8 bits
-of the argument passed to
-.Xr _exit 2
-or
-.Xr exit 3
-by the child.
-.It Fn WTERMSIG status
-If
-.Fn WIFSIGNALED status
-is true, evaluates to the number of the signal
-that caused the termination of the process.
-.It Fn WCOREDUMP status
-If
-.Fn WIFSIGNALED status
-is true, evaluates as true if the termination
-of the process was accompanied by the creation of a core file
-containing an image of the process when the signal was received.
-.It Fn WSTOPSIG status
-If
-.Fn WIFSTOPPED status
-is true, evaluates to the number of the signal
-that caused the process to stop.
-.El
-.Sh NOTES
-See
-.Xr sigaction 2
-for a list of termination signals.
-A status of 0 indicates normal termination.
-.Pp
-If a parent process terminates without
-waiting for all of its child processes to terminate,
-the remaining child processes are assigned the parent
-process 1 ID (the init process ID).
-.Pp
-If a signal is caught while any of the
-.Fn wait
-calls are pending,
-the call may be interrupted or restarted when the signal-catching routine
-returns,
-depending on the options in effect for the signal;
-see discussion of
-.Dv SA_RESTART
-in
-.Xr sigaction 2 .
-.Pp
-The implementation queues one
-.Dv SIGCHLD
-signal for each child process whose
-status has changed, if
-.Fn wait
-returns because the status of a child process is available, the pending
-SIGCHLD signal associated with the process ID of the child process will
-be discarded.
-Any other pending
-.Dv SIGCHLD
-signals remain pending.
-.Pp
-If
-.Dv SIGCHLD
-is blocked,
-.Fn wait
-returns because the status of a child process is available, the pending
-.Dv SIGCHLD
-signal will be cleared unless another status of the child process
-is available.
-.Sh RETURN VALUES
-If
-.Fn wait
-returns due to a stopped, continued,
-or terminated child process, the process ID of the child
-is returned to the calling process.
-Otherwise, a value of \-1
-is returned and
-.Va errno
-is set to indicate the error.
-.Pp
-If
-.Fn wait4 ,
-.Fn wait3 ,
-or
-.Fn waitpid
-returns due to a stopped, continued,
-or terminated child process, the process ID of the child
-is returned to the calling process.
-If there are no children not previously awaited,
--1 is returned with
-.Va errno
-set to
-.Er ECHILD .
-Otherwise, if
-.Dv WNOHANG
-is specified and there are
-no stopped, continued or exited children,
-0 is returned.
-If an error is detected or a caught signal aborts the call,
-a value of -1
-is returned and
-.Va errno
-is set to indicate the error.
-.Sh ERRORS
-The

-will fail and return immediately if:
-.Bl -tag -width Er
-.It Bq Er ECHILD
-The calling process has no existing unwaited-for
-child processes.
-.It Bq Er ECHILD

-.Fn pwritev "int d" "const struct iovec *iov" "int iovcnt" "off_t offset"
-.Sh DESCRIPTION
-The
-.Fn write
-system call
-attempts to write
-.Fa nbytes
-of data to the object referenced by the descriptor
-.Fa d
-from the buffer pointed to by
-.Fa buf .
-The
-.Fn writev
-system call
-performs the same action, but gathers the output data
-from the
-.Fa iovcnt
-buffers specified by the members of the
-.Fa iov
-array: iov[0], iov[1], ..., iov[iovcnt\|-\|1].
-The
-.Fn pwrite
-and
-.Fn pwritev
-system calls
-perform the same functions, but write to the specified position in
-the file without modifying the file pointer.
-.Pp
-For
-.Fn writev
-and
-.Fn pwritev ,
-the
-.Fa iovec
-structure is defined as:
-.Pp
-.Bd -literal -offset indent -compact
-struct iovec {
- void *iov_base; /* Base address. */
- size_t iov_len; /* Length. */
-};
-.Ed
-.Pp
-Each
-.Fa iovec
-entry specifies the base address and length of an area
-in memory from which data should be written.
-The
-.Fn writev
-system call
-will always write a complete area before proceeding
-to the next.
-.Pp
-On objects capable of seeking, the
-.Fn write
-starts at a position
-given by the pointer associated with
-.Fa d ,
-see
-.Xr lseek 2 .
-Upon return from
-.Fn write ,
-the pointer is incremented by the number of bytes which were written.
-.Pp
-Objects that are not capable of seeking always write from the current
-position.
-The value of the pointer associated with such an object
-is undefined.
-.Pp
-If the real user is not the super-user, then
-.Fn write
-clears the set-user-id bit on a file.
-This prevents penetration of system security
-by a user who
-.Dq captures
-a writable set-user-id file
-owned by the super-user.
-.Pp
-When using non-blocking I/O on objects such as sockets that are subject
-to flow control,
-.Fn write
-and
