-The

-This implementation does not support shared semaphores, and reports this fact
-by setting

-This is perhaps a stretch of the intention of POSIX, but is

-.Sh DESCRIPTION
-The
-.Fn sem_open
-function creates or opens the named semaphore specified by
-.Fa name .
-The returned semaphore may be used in subsequent calls to
-.Fn sem_getvalue ,
-.Fn sem_wait ,
-.Fn sem_trywait ,
-.Fn sem_post
-and
-.Fn sem_close .
-.Pp
-The following bits may be set in the
-.Fa oflag
-argument:
-.Bl -tag -width ".Dv O_CREAT"
-.It Dv O_CREAT
-Create the semaphore if it does not already exist.
-.Pp
-The third argument to the call to
-.Fn sem_open
-must be of type
-.Vt mode_t
-and specifies the mode for the semaphore.
-Only the
-.Dv S_IWUSR ,
-.Dv S_IWGRP ,
-and
-.Dv S_IWOTH
-bits are examined;
-it is not possible to grant only

-permission on a semaphore.
-The mode is modified according to the process's file creation
-mask; see
-.Xr umask 2 .
-.Pp
-The fourth argument must be an
-.Vt "unsigned int"
-and specifies the initial value for the semaphore,
-and must be no greater than
-.Dv SEM_VALUE_MAX .
-.It Dv O_EXCL
-Create the semaphore if it does not exist.
-If the semaphore already exists,
-.Fn sem_open
-will fail.
-This flag is ignored unless
-.Dv O_CREAT
-is also specified.
-.El
-.Pp
-The
-.Fn sem_close
-function closes a named semaphore that was opened by a call to
-.Fn sem_open .
-.Pp
-The
-.Fn sem_unlink
-function removes the semaphore named
-.Fa name .
-Resources allocated to the semaphore are only deallocated when all
-processes that have the semaphore open close it.
-.Sh RETURN VALUES
-If successful,
-the
-.Fn sem_open
-function returns the address of the opened semaphore.
-If the same
-.Fa name
-argument is given to multiple calls to
-.Fn sem_open
-by the same process without an intervening call to
-.Fn sem_close ,
-the same address is returned each time.
-If the semaphore cannot be opened,
-.Fn sem_open
-returns
-.Dv SEM_FAILED
-and the global variable
-.Va errno
-is set to indicate the error.

-The

-The semaphore exists and the permissions specified by
-.Fa oflag
-at the time it was created deny access to the this process.

-The semaphore does not exist, but permission to create it is denied.
-.It Bq Er EEXIST
-.Dv O_CREAT
