-/*! \file
- * \brief
- * Functions to marshall and unmarshall various system data structures. We
- * use a printable ascii format that is as close to various system config
- * files as reasonable (e.g. /etc/passwd format).
- *
- * We are not forgiving with unmarhsalling misformatted buffers. In
- * particular whitespace in fields is not ignored. So a formatted password
- * entry "brister  :1364:100:...." will yield a username of "brister   "
- *
- * We potentially do a lot of mallocs to fill fields that are of type
- * (char **) like a hostent h_addr field. Building (for example) the
- * h_addr field and its associated addresses all in one buffer is
- * certainly possible, but not done here.
- *
- * The following description is true for all the marshalling functions:
- *
- * int irp_marshall_XX(struct yyyy *XX, char **buffer, size_t *len);
- *
- * The argument XX (of type struct passwd for example) is marshalled in the
- * buffer pointed at by *BUFFER, which is of length *LEN. Returns 0
- * on success and -1 on failure. Failure will occur if *LEN is
- * smaller than needed.
- *
- * If BUFFER is NULL, then *LEN is set to the size of the buffer
- * needed to marshall the data and no marshalling is actually done.
- *
- * If *BUFFER is NULL, then a buffer large enough will be allocated
- * with memget() and the size allocated will be stored in *LEN. An extra 2
- * bytes will be allocated for the client to append CRLF if wanted. The
- * value of *LEN will include these two bytes.
- *
- * All the marshalling functions produce a buffer with the fields
- * separated by colons (except for the hostent marshalling, which uses '@'
- * to separate fields). Fields that have multiple subfields (like the
- * gr_mem field in struct group) have their subparts separated by
- * commas.
- *
- * int irp_unmarshall_XX(struct YYYYY *XX, char *buffer);
- *
- * The unmashalling functions break apart the buffer and store the
- * values in the struct pointed to by XX. All pointer values inside
- * XX are allocated with malloc. All arrays of pointers have a NULL
- * as the last element.

- *  Notes:
- *	We hope to create a complete set of thread-safe entry points someday,
- *	which will mean a set of getXbyY() functions that take as an argument
- *	a pointer to the map class, which will have a pointer to the private
- *	data, which will be used preferentially to the static variables that
- *	are necessary to support the "classic" interface.  This "classic"
- *	interface will then be reimplemented as stubs on top of the thread
- *	safe modules, and will keep the map class pointers as their only
- *	static data.  HOWEVER, we are not there yet.  So while we will call
- *	the just-barely-converted map class methods with map class pointers,
- *	right now they probably all still use statics.  We're not fooling
- *	anybody, and we're not trying to (yet).

-/*! \file
- * Issues to be discussed:
- *\li  Thread safe-ness must be checked.
- *\li  Return values.  There are nonstandard return values defined and used
- *   in the source code.  This is because RFC2553 is silent about which error
- *   code must be returned for which situation.
- *\li  IPv4 classful (shortened) form.  RFC2553 is silent about it.  XNET 5.2
- *   says to use inet_aton() to convert IPv4 numeric to binary (allows
- *   classful form as a result).
- *   current code - disallow classful form for IPv4 (due to use of inet_pton).
- *\li  freeaddrinfo(NULL).  RFC2553 is silent about it.  XNET 5.2 says it is
- *   invalid.
- *   current code - SEGV on freeaddrinfo(NULL)
- * Note:
- *\li  We use getipnodebyname() just for thread-safeness.  There's no intent
- *   to let it do PF_UNSPEC (actually we never pass PF_UNSPEC to
- *   getipnodebyname().
- *\li  The code filters out AFs that are not supported by the kernel,
- *   when globbing NULL hostname (to loopback, or wildcard).  Is it the right
- *   thing to do?  What is the relationship with post-RFC2553 AI_ADDRCONFIG
- *   in ai_flags?
- *\li  (post-2553) semantics of AI_ADDRCONFIG itself is too vague.
- *   (1) what should we do against numeric hostname (2) what should we do
- *   against NULL hostname (3) what is AI_ADDRCONFIG itself.  AF not ready?
- *   non-loopback address configured?  global address configured?
- * \par Additional Issue:
- *  To avoid search order issue, we have a big amount of code duplicate
- *   from gethnamaddr.c and some other places.  The issues that there's no
- *   lower layer function to lookup "IPv4 or IPv6" record.  Calling
- *   gethostbyname2 from getaddrinfo will end up in wrong search order, as
- *   follows:
- *	\li The code makes use of following calls when asked to resolver with
- *	  ai_family  = PF_UNSPEC:
- *\code		getipnodebyname(host, AF_INET6);
- *		getipnodebyname(host, AF_INET);
- *\endcode
- *	\li  This will result in the following queries if the node is configure to
- *	  prefer /etc/hosts than DNS:
- *\code
- *		lookup /etc/hosts for IPv6 address
- *		lookup DNS for IPv6 address
- *		lookup /etc/hosts for IPv4 address
- *		lookup DNS for IPv4 address
- *\endcode
- *	  which may not meet people's requirement.
- *	 \li The right thing to happen is to have underlying layer which does
- *	  PF_UNSPEC lookup (lookup both) and return chain of addrinfos.
- *	  This would result in a bit of code duplicate with _dns_ghbyname() and
- *	  friends.

-.Sh DESCRIPTION
-The
-.Fn REQUIRE ,
-.Fn ENSURE ,
-.Fn INSIST ,
-and
-.Fn INVARIANT
-macros evaluate a boolean expression, and if it is false, they invoke the
-current assertion failure callback.  The default callback will print a message
-to 
-.Li stderr
-describing the failure, and then cause the program to dump core.
-If the
-.Dq Fn _ERR
-variant of the assertion is used, the callback will include
-.Fn strerror "errno"
-in its message.
-.Pp
-Each assertion type has an associated
-.Li CHECK
-macro.  If this macro's value is
-.Dq 0
-when
-.Dq "<isc/assertions.h>"
-is included, then assertions of that type will not be checked.  E.g.
-.Pp
-.Dl #define CHECK_ENSURE 0
-.Pp
-will disable checking of
-.Fn ENSURE
-and
-.Fn ENSURE_ERR .
-The macros
-.Li CHECK_ALL
-and
-.Li CHECK_NONE
-may also be used, respectively specifying that either all or none of the
-assertion types should be checked.
-.Pp
-.Fn set_assertion_failure_callback
-specifies the function to call when an assertion fails.
-.Pp
-When an
-.Fn assertion_failure_callback
-is called, the 
-.Fa filename
-and
-.Fa line
-arguments specify the filename and line number of the failing assertion.
-The
-.Fa type
-is one of:
-.Bd -literal -offset indent
-assert_require
-assert_ensure
-assert_insist
-assert_invariant
-.Ed
-.Pp
-and may be used by the callback to determine the type of the failing
-assertion.
-.Fa condition
-is the literal text of the assertion that failed. 
-.Fa print_errno
-will be non-zero if the callback should print
-.Fa strerror "errno"
-as part of its output.
-.Pp
-.Fn assertion_type_to_text
-returns a textual representation of
-.Fa type .
-For example,
-.Fn assertion_type_to_text "assert_require"
-returns the string
-.Dq REQUIRE .

-/* (From RFC1521 and draft-ietf-dnssec-secext-03.txt)
-   The following encoding technique is taken from RFC1521 by Borenstein
-   and Freed.  It is reproduced here in a slightly edited form for
-   convenience.
-
-   A 65-character subset of US-ASCII is used, enabling 6 bits to be
-   represented per printable character. (The extra 65th character, "=",
-   is used to signify a special processing function.)
-
-   The encoding process represents 24-bit groups of input bits as output
-   strings of 4 encoded characters. Proceeding from left to right, a
-   24-bit input group is formed by concatenating 3 8-bit input groups.
-   These 24 bits are then treated as 4 concatenated 6-bit groups, each
-   of which is translated into a single digit in the base64 alphabet.
-
-   Each 6-bit group is used as an index into an array of 64 printable
-   characters. The character referenced by the index is placed in the
-   output string.

-   Special processing is performed if fewer than 24 bits are available
-   at the end of the data being encoded.  A full encoding quantum is
-   always completed at the end of a quantity.  When fewer than 24 input
-   bits are available in an input group, zero bits are added (on the
-   right) to form an integral number of 6-bit groups.  Padding at the
-   end of the data is performed using the '=' character.
-
-   Since all base64 input is an integral number of octets, only the
-         -------------------------------------------------                       
-   following cases can arise:
-   
-       (1) the final quantum of encoding input is an integral
-           multiple of 24 bits; here, the final unit of encoded
-	   output will be an integral multiple of 4 characters
-	   with no "=" padding,
-       (2) the final quantum of encoding input is exactly 8 bits;
-           here, the final unit of encoded output will be two
-	   characters followed by two "=" padding characters, or
-       (3) the final quantum of encoding input is exactly 16 bits;
-           here, the final unit of encoded output will be three
-	   characters followed by one "=" padding character.

-.Dt BITNCMP 3
-.Os BSD 4
-.Sh NAME
-.Nm bitncmp 
-.Nd compare bit masks
-.Sh SYNOPSIS
-.Ft int
-.Fn bitncmp "const void *l" "const void *r" "int n"
-.Sh DESCRIPTION
-The function
-.Fn bitncmp
-compares the
-.Dq Fa n
-most-significant bits of the two masks pointed to by
-.Dq Fa l
-and
-.Dq Fa r ,
-and returns an integer less than, equal to, or greater than 0, according to
-whether or not
-.Dq Fa l
-is lexicographically less than, equal to, or greater than
-.Dq Fa r
-when taken to be unsigned characters (this behaviour is just like that of
-.Xr memcmp 3 ) .
-.Pp
-.Sy NOTE :
-.Fn Bitncmp 
-assumes 
-.Sy network byte order ;
-this means that the fourth octet of 
-.Li 192.5.5.240/28 
-.Li 0x11110000 .
-.Sh RETURN VALUES
-.Fn Bitncmp
-returns values in the manner of
-.Xr memcmp 3 :
-.Bd -ragged -offset indent
-+1 if 
-.Dq Fa 1
-is greater than 
-.Dq Fa r ;
-.Pp
--1 if 
-.Dq Fa l
-is less than 
-.Dq Fa r ; 
-and
-.Pp
-0 if 
-.Dq Fa l
-is equal to
-.Dq Fa r ,
-.Ed
-.Pp
-where 
-.Dq Fa l
-and 
-.Dq Fa r
-are both interpreted as strings of unsigned characters (through bit 
-.Dq Fa n . )
-.Sh SEE ALSO
-.Xr memcmp 3 .

-.Sh DESCRIPTION
-This library provides multiple outstanding asynchronous timers and I/O
-to a cooperating application.  The model is similar to that of the X
-Toolkit, in that events are registered with the library and the application
-spends most of its time in the
-.Fn evMainLoop
-function.  If an application already has a main loop, it can safely register
-events with this library as long as it periodically calls the
-.Fn evGetNext
-and
-.Fn evDispatch
-functions.  (Note that
-.Fn evGetNext
-has both polling and blocking modes.)
-.Pp
-The function
-.Fn evCreate
-creates an event context which is needed by all the other functions in this
-library.  All information used internally by this library is bound to this
-context, rather than to static storage.  This makes the library 
-.Dq thread safe ,
-and permits other library functions to use events without
-disrupting the application's use of events.
-.Pp
-The function
-.Fn evDestroy
-destroys a context that has been created by
-.Fn evCreate .
-All dynamic memory bound to this context will be freed.  An implicit
-.Fn evTimerClear
-will be done on all timers set in this event context.  An implicit
-.Fn evDeselectFD
-will be done on all file descriptors selected in this event context.
-.Pp
-The function
-.Fn evGetNext
-potentially waits for and then retrieves the next asynchronous event,
-placing it in the object of the
-.Fa ev
-pointer argument.  The following
-.Fa options
-are available:
-.Fa EV_POLL ,
-meaning that
-.Fn evGetNext
-should not block, but rather return
-.Dq Fa -1
-with
-.Fa errno
-set to
-.Fa EWOULDBLOCK
-if no events have occurred;
-.Fa EV_WAIT ,
-which tells
-.Fn evGetNext
-to block internally until the next event occurs; and
-.Fa EV_NULL ,
-which tells
-.Fn evGetNext
-that it should return a special 
-.Dq no-op 
-event, which is ignored by
-.Fn evDispatch
-but handled correctly by
-.Fn evDrop .
-.Fa EV_NULL
-can be necessary to the correct functioning of a caller\-written equivilent to
-.Fn evMainLoop ,
-wherein perterbations caused by external system events must be polled for, and
-the default behaviour of internally ignoring such events is undesirable.
-Note that
-.Fa EV_POLL
-and
-.Fa EV_WAIT
-are mutually exclusive.
-.Pp
-The function
-.Fn evDispatch
-dispatches an event retrieved by
-.Fn evGetNext .
-This usually involves calling the function that was associated with the event
-when the event was registered with
-.Fn evSetTimer ,
-.Fn evResetTimer ,
-or
-.Fn evSelectFD .
-All events retrieved by
-.Fn evGetNext
-must be given over to
-.Fn evDispatch
-at some point, since there is some dynamic memory associated with each event.
-.Pp
-The function
-.Fn evDrop
-deallocates dynamic memory that has been allocated by
-.Fn evGetNext .
-Calling
-.Fn evDispatch
-has the side effect of calling
-.Fn evDrop ,
-but if you are going to drop the event rather than dispatch it, you will have
-to call
-.Fn evDrop
-directly.
-.Pp
-The function
-.Fn evMainLoop
-is just:
-.Bd -literal -offset indent
-while ((x = evGetNext(opaqueCtx, &event, EV_WAIT)) == 0)
-	if ((x = evDispatch(opaqueCtx, event)) < 0)
-		break;
-return (x);
-.Ed
-.Pp
-In other words, get events and dispatch them until an error occurs.  One such
-error would be that all the events under this context become unregistered; in
-that event, there will be nothing to wait for and
-.Fn evGetNext
-becomes an undefined operation.
-.Pp
-The function
-.Fn evConsTime
-is a constructor for
-.Dq Fa struct timespec
-which allows these structures to be created and then passed as arguments to
-other functions without the use of temporary variables.  (If C had inline
-constructors, there would be no need for this function.)
-.Pp
-The functions
-.Fn evTimeSpec
-and
-.Fn evTimeVal 
-are utilities which allow the caller to convert a
-.Dq Fa struct timeval
-to a 
-.Dq Fa struct timespec
-(the function of
-.Fn evTimeSpec )
-or vice versa (the function of
-.Fn evTimeVal ) .
-Note that the name of the function indicates the type of the return value.
-.Pp
-The function
-.Fn evAddTime
-adds two
-.Dq Fa struct timespec
-values and returns the result as a
-.Dq Fa struct timespec .
-.Pp
-The function
-.Fn evSubTime
-subtracts its second
-.Dq Fa struct timespec
-argument from its first
-.Dq Fa struct timespec
-argument and returns the result as a
-.Dq Fa struct timespec .
-.Pp
-The function
-.Fn evCmpTime
-compares its two
-.Dq Fa struct timespec
-arguments and returns an
-.Dq Fa int
-that is less than zero if the first argument specifies an earlier time than
-the second, or more than zero if the first argument specifies a later time
-than the second, or equal to zero if both arguments specify the same time.
-.Pp
-The function
-.Fn evNowTime
-returns a
-.Dq Fa struct timespec
-which either describes the current time
-(using
-.Xr clock_gettime 2 or
-.Xr gettimeofday 2 ) ,
-if successful, or has its fields set to zero, if there is an error.
-(In the latter case, the caller can check
-.Va errno ,
-since it will be set by
-.Xr gettimeofday 2 . )
-The timestamp returned may not be UTC time if
-the "monotime" option has been enabled with
-.Fn evSetOption .
-.Pp
-The function 
-.Fn evUTCTime
-is like 
-.Fn evNowTime
-except the result is always on the UTC timescale.
-.Pp
-The function
-.Fn evLastEventTime 
-returns the
-.Dq Fa struct timespec
-which describes the last time that certain events happened to the 
-event context indicated by 
-.Fa opaqueCtx .
-This value is updated by
-.Fn evCreate 
-and
-.Fn evGetNext 
-(upon entry and after
-.Xr select 2
-returns); it is routinely compared with other times in the internal handling
-of, e.g., timers.
-.Pp
-The function
-.Fn evSetTimer
-registers a timer event, which will be delivered as a function call to the
-function specified by the
-.Fa func
-argument.  The event will be delivered at absolute time
-.Fa due ,
-and then if time
-.Fa inter
-is not equal to
-.Dq Fn evConsTime 0 0 ,
-subsequently at intervals equal to time
-.Fa inter .
-As a special case, specifying a
-.Fa due
-argument equal to
-.Dq Fn evConsTime 0 0
-means 
-.Dq due immediately .
-The
-.Fa opaqueID
-argument, if specified as a value other than
-.Fa NULL ,
-will be used to store the resulting 
-.Dq timer \s-1ID\s+1 , 
-useful as an argument to
-.Fn evClearTimer .
-Note that in a 
-.Dq one\-shot 
-timer (which has an
-.Fa inter
-argument equal to
-.Dq Fa evConsTime(0,0) )
-the user function
-.Fa func
-should deallocate any dynamic memory that is uniquely bound to the
-.Fa uap ,
-since no handles to this memory will exist within the event library
-after a one\-shot timer has been delivered.
-.Pp
-The function
-.Fn evResetTimer
-resets the values of the timer specified by
-.Fa id
-to the given arguments.  The arguments are the same as in the description of
-.Fn evSetTimer
-above.
-.Pp
-The function
-.Fn evClearTimer
-will unregister the timer event specified by
-.Fa id .
-Note that if the
-.Fa uap
-specified in the corresponding
-.Fn evSetTimer
-call is uniquely bound to any dynamic memory, then that dynamic memory should
-be freed by the caller before the handle is lost.  After a call to
-.Fn evClearTimer ,
-no handles to this
-.Fa uap
-will exist within the event library.
-.Pp
-The function
-.Fn evConfigTimer
-can be used to manipulate other aspects of a timer.
-Currently two modes are defined "rate" and "interval" which affect the
-way recurrent timers are scheduled.
-The default mode is "interval" where the event gets scheduled
-.Fa inter
-after last time it was run.
-If mode "rate" is selected the event gets scheduled
-.Fa inter
-after last time it was scheduled.
-For both "rate" and "interval" the numerical argument
-.Fa value
-is ignored.
-.Pp
-The function
-.Fn evSetIdleTimer 
-is similar to (and built on)
-.Fn evSetTimer ;
-it registers an idle timer event which provides for the function call to
-.Fa func
-to occur.  However, for an
-.Em idle
-timer, the call will occur after at least
-.Dq Fa max_idle
-time has passed since the time the idle timer was
-.Dq last touched ;
-originally, this is set to the time returned by
-.Fn evLastEventTime 
-(described above) for the event context specified by 
-.Fa opaqueCtx .  
-This is a 
-.Dq one\-shot 
-timer, but the time at which the
-.Fa func
-is actually called can be changed by recourse to
-.Fn evTouchIdleTimer
-(described below).  The pointer to the underlying 
-.Dq timer \s-1ID\s+1 
-is returned in
-.Fa opaqueID ,
-if it is
-.No non- Ns Dv NULL .
-.Pp
-The
-.Fn evTouchIdleTimer 
-function updates the idle timer associated with
-.Fa id ,
-setting its idea of the time it was last accessed to the value returned by
-.Fn evLastEventTime
-(described above) for the event context specified by
-.Fa opaqueCtx .
-This means that the idle timer will expire after at least
-.Fa max_idle
-time has passed since this (possibly new) time, providing a caller mechanism
-for resetting the call to the
-.Fa func
-associated with the idle timer.  (See the description of
-.Fn evSetIdleTimer ,
-above, for information about
-.Fa func
-and
-.Fa max_idle . )
-.Pp
-The
-.Fn evResetIdleTimer
-function reschedules a timer and resets the callback function and its argument.
-Note that resetting a timer also ``touches'' it.
-.Pp
-The
-.Fn evClearIdleTimer
-function unregisters the idle timer associated with
-.Fa id .
-See the discussion under
-.Fn evClearTimer , 
-above, for information regarding caller handling of the
-.Fa uap
-associated with the corresponding
-.Fn evSetIdleTimer
-call.
-.Pp
-The function
-.Fn evWaitFor
-places the function
-.Fa func
-on the given event context's wait queue with the associated (possibly
-.Dv NULL )
-.Dq Fa tag ;
-if 
-.Fa id
-is 
-.No non- Ns Dv NULL ,
-then it will contain the 
-.Dq wait \s-1ID\s+1 
-associated with the created queue element.
-.Pp
-The function
-.Fn evDo 
-marks 
-.Em all
-of the 
-.Dq waiting 
-functions in the given event context's wait queue with the associated (possibly
-.Dv NULL )
-.Dq Fa tag
-as runnable.  This places these functions in a
-.Dq done
-queue which will be read by
-.Fn evGetNext .
-.Pp
-The function
-.Fn evUnwait 
-will search for the
-.Dq wait \s-1ID\s+1 
-.Fa id
-in the wait queue of the given event context; if an element with the given
-.Fa id 
-is not found, then the
-.Dq done
-queue of that context is searched.  If found, the queue element is removed
-from the appropriate list.
-.Pp
-The function
-.Fn evDefer
-causes a function (specified as
-.Fa func ,
-with argument
-.Fa uap )
-to be dispatched at some later time.  Note that the
-.Fa tag
-argument to
-.Fa func
-will always be
-.Fa NULL
-when dispatched.
-.Pp
-The function
-.Fn evSelectFD
-registers a file I/O event for the file descriptor specified by
-.Fa fd .
-Bits in the
-.Fa eventmask
-argument are named
-.Fa EV_READ ,
-.Fa EV_WRITE ,
-and
-.Fa EV_EXCEPT .
-At least one of these bits must be specified.  If the
-.Fa id
-argument is not equal to
-.Fa NULL ,
-it will be used to store a unique ``file event \s-1ID\s+1'' for this event,
-which is useful in subsequent calls to
-.Fn evDeselectFD .
-A file descriptor will be made nonblocking using the
-.Fa O_NONBLOCK
-flag with
-.Xr fcntl 2
-on its first concurrent registration via
-.Fn evSelectFD .
-An
-.Fn evSelectFD
-remains in effect until cancelled via
-.Fn evDeselectFD .
-.Pp
-The function
-.Fn evDeselectFD
-unregisters the ``file event'' specified by the
-.Fa id
-argument.  If the corresponding
-.Fa uap
-uniquely points to dynamic memory, that memory should be freed before its
-handle is lost, since after a call to
-.Fn evDeselectFD ,
-no handles to this event's
-.Fa uap
-will remain within the event library.  A file descriptor will be taken out of
-nonblocking mode (see
-.Fa O_NONBLOCK
-and
-.Xr fcntl 2 )
-when its last event registration is removed via
-.Fn evDeselectFD ,
-if it was in blocking mode before the first registration via
-.Fn evSelectFD .
-.Pp
-The function
-.Fn evConsIovec
-is a constructor for a single
-.Ft struct iovec
-structure, which is useful for
-.Fn evWrite
-and
-.Fn evRead .
-.Pp
-The functions
-.Fn evWrite
-and
-.Fn evRead
-start asynchronous stream I/O operations on file descriptor
-.Fa fd .
-The data to be written or read is in the scatter/gather descriptor specified by
-.Fa iov
-and
-.Fa cnt .
-The supplied function
-.Fa func
-will be called with argument
-.Fa uap
-when the I/O operation is complete.  If
-.Fa id
-is not
-.Fa NULL ,
-it will be filled a with the stream event identifier suitable for use with
-.Fn evCancelRW .
-.Pp
-The function
-.Fn evCancelRW
-extinguishes an outstanding
-.Fn evWrite
-or
-.Fn evRead
-call.  System I/O calls cannot always be cancelled, but you are guaranteed
-that the
-.Fa func
-function supplied to
-.Fn evWrite
-or
-.Fn evRead
-will not be called after a call to
-.Fn evCancelRW .
-Care should be taken not to deallocate or otherwise reuse the space pointed
-to by the segment descriptors in
-.Fa iov
-unless the underlying file descriptor is closed first.
-.Pp
-The function
-.Fn evTimeRW
-sets the stream associated with the given stream \s-1ID\s+1 
-.Dq Fa id
-to have the idle timer associated with the timer \s-1ID\s+1 
-.Dq Fa timer .
-.Pp
-The function
-.Fn evUntimeRW
-says that the stream associated with the given stream \s-1ID\s+1
-.Dq Fa id
-should ignore its idle timer, if present.
-.Pp
-The functions
-.Fn evListen ,
-.Fn evConnect ,
-and
-.Fn evCancelConn
-can be used to manage asynchronous incoming and outgoing socket connections.
-Sockets to be used with these functions should first be created with
-.Xr socket 2
-and given a local name with
-.Xr bind 2 .
-It is extremely unlikely that the same socket will ever be
-useful for both incoming and outgoing connections.  The
-.Fa id
-argument to
-.Fn evListen
-and
-.Fn evConnect
-is either
-.Fa NULL
-or the address of a
-.Ft evFileID
-variable which can then be used in a subsequent call to
-.Fn evCancelConn .
-.Pp
-After a call to
-.Fn evListen ,
-each incoming connection arriving on
-.Fa fd
-will cause
-.Fa func
-to be called with
-.Fa uap
-as one of its arguments.
-.Fn evConnect
-initiates an outgoing connection on
-.Fa fd
-to destination address
-.Fa ra
-(whose length is
-.Fa ralen ) .
-When the connection is complete,
-.Fa func
-will be called with
-.Fa uap
-as one of its arguments.  The argument
-.Fa fd
-to
-.Fn \*(lp*func\*(rp
-will be
-.Fa -1
-if an error occurred that prevented this connection from completing 
-successfully.  In this case
-.Fn errno
-will have been set and the socket described by
-.Fa fd
-will have been closed.  The
-.Fn evCancelConn
-function will prevent delivery of all pending and subsequent
-events for the outstanding connection.  The
-.Fn evHold
-function will suspend the acceptance of new connections on the listener
-specified by
-.Fa id .
-Connections will be queued by the protocol stack up to the system's limit.  The
-.Fn evUnhold
-function will reverse the effects of
-.Fn evHold ,
-allowing incoming connections to be delivered for listener
-.Fa id .
-The
-.Fn evTryAccept
-function will poll the listener specified by
-.Fa id ,
-accepting a new connection if one is available, and queuing a connection event
-for later retrieval by
-.Fn evGetNext .
-If the connection event queued is an accept error(), sys_errno will contain
-the error code; otherwise it will be zero.  All connection events queued by
-.Fn evTryAccept
-will be delivered by
-.Fn evGetNext
-before a new select is done on the listener.
-.Pp
-The function
-.Fn evSetDebug
-sets the debugging
-.Fa level
-and diagnostic
-.Fa output
-file handle for an event context.  Greater numeric levels will
-result in more verbose output being sent to the output FILE during program
-execution.
-.Pp
-The function
-.Fn evPrintf
-prints a message with the format
-.Dq Fa fmt
-and the following arguments (if any), on the output stream associated
-with the event context pointed to by
-.Fa ctx .
-The message is output if the event context's debug level is greater than
-or equal to the indicated
-.Fa level .
-.Pp
-The function
-.Fn evInitID
-will initialize an opaque 
-.Dq evConn \s-1ID\s+1 , 
-.Dq evFile \s-1ID\s+1 , 
-.Dq evStream \s-1ID\s+1 , 
-.Dq evTimer \s-1ID\s+1 , 
-.Dq evWait \s-1ID\s+1 , 
-.Dq evContext , 
-or
-.Dq evEvent ,
-which is passed by reference to a state which
-.Fn evTestID
-will recognize.
-This is useful to make a handle as "not in use".
-.Pp
-The function
-.Fn evTestID
-will examine an opaque \s-1ID\s+1 and return
-.Dq TRUE
-only if it is not in its initialized state.
-.Pp
-The functions
-.Fn evGetOption
-and 
-.Fn evSetOption
-can be used to inspect and modify options.
-Currently there is only one option,  "monotime" and it is global for all 
-instances of eventlib so the ctx argument must be passed as NULL.
-.Pp
-The default value for the "monotime" option is zero which selects
-the UTC timescale.
-When set to a value of one, eventlib will use the
-CLOCK_MONOTONIC timescale from
-.Xr clock_gettime
-instead.
-The CLOCK_MONOTONIC timescale is never stepped and should
-run at a rate as close to TAI as possible, so it is unaffected
-when the system clock is set.
-If timerevents should run at a predictable rate, set the value
-to one, of they should run at a predictable time of day, leave
-it at zero.
-If the CLOCK_MONOTONIC timescale is not available on the system,
-attempts to set/get this option will fail.
-.Sh RETURN VALUES
-All the functions whose return type is
-.Dq Fa int
-use the standard convention of returning zero (0) to indicate success, or
-returning
-.Dq Fa -1
-and setting
-.Fa errno
-to indicate failure.
-.Sh FILE
-.Pa heap.h ,
-which is in the 
-.Pa src/lib/isc
-directory of the current 
-.Sy BIND
-distribution.
-.Sh ERRORS
-The possible values for
-.Fa errno
-when one of the
-.Dq Fa int
-functions in this library returns
-.Dq Fa -1
-include those of the Standard C Library and also:
-.Bl -tag -width EWOULDBLOCKAA
-.It Bq Er EINVAL
-Some function argument has an unreasonable value.
-.It Bq Er EINVAL
-The specified file descriptor has an integer value greater than the default
-.Fa FD_SETSIZE ,
-meaning that the application's limit is higher than the library's.
-.It Bq Er ENOENT
-The specified 
-.Dq event \s-1ID\s+1 
-does not exist.
-.It Bq Er EWOULDBLOCK
-No events have occurred and the
-.Fa EV_POLL
-option was specified.
-.It Bq Er EBADF
-The specified signal was unblocked outside the library.

-.Sh DESCRIPTION
-These functions implement heap\-based priority queues.  The user defines a
-priority scheme, and provides a function for comparison of the priority
-of heap elements
-(see the description of the
-.Ft heap_higher_priority_func
-function pointer, below).
-.Pp
-Each of the functions depends upon the
-.Ft heap_context
-type, which is a pointer to a
-.Ft struct heap_context 
-.Pq see Pa heap.h No for more information .
-.Pp
-The
-.Pa heap.h
-header file also defines the following set of function
-function pointers:
-.Bd -literal -offset indent
-typedef int (*heap_higher_priority_func)(void *, void *);
-typedef void (*heap_index_func)(void *, int);
-typedef void (*heap_for_each_func)(void *, void *);
-.Ed
-.Pp
-These are pointers to user-defined functions.
-The 
-.Ft heap_higher_priority_func
-type is a pointer to a function which compares two
-different heap (queue) elements and returns an
-.Ft int
-which answers the question, "Does the first queue element 
-have a higher priority than the second?"  In other words, 
-a function pointer of this type 
-.Em must 
-return a number greater than zero
-if the element indicated by the first argument is of a higher priority than 
-that indicated by the second element, and zero otherwise.  
-.Pp
-The other two function pointers are documented in the descriptions
-of 
-.Fn heap_new
-.Pq Va heap_index_func
-and
-.Fn heap_for_each
-.Pq Va heap_for_each_func ,
-below.
-.Pp
-The function
-.Fn heap_new
-initializes a 
-.Ft struct heap_context
-and returns a pointer to it.  The
-.Fa higher_priority
-function pointer 
-.Em must 
-be 
-.No non\- Ns Dv NULL .
-As explained above, this refers to a 
-function supplied by the user which compares the priority of two different
-queue or heap elements; see above for more information. 
-The second argument, 
-.Fa index ,
-is a pointer to a user-defined function whose arguments are
-a heap element and its index in the heap.
-.Fa Index 
-is intended to provide the user a means of knowing the internal index
-of an element in the heap while maintaining the opacity of the implementation;
-since the user has to know the actual indexes of heap elements in order to use,
-e.g., 
-.Fn heap_delete
-or
-.Fn heap_element ,
-the user 
-.Fa index
-function could store the index in the heap element, itself.  If 
-.Fa index
-is 
-.No non\- Ns Dv NULL ,
-then it is called 
-.Em whenever 
-the index of an element changes, allowing the user to stay up\-to\-date
-with index changes.
-The last argument, 
-.Fa array_size_increment
-will be used, as its name suggests, by
-.Xr malloc 3
-or
-.Xr realloc 3
-to increment the array which implements the heap; if zero, a default value 
-will be used.
-.Pp
-The
-.Fn heap_free
-function frees the given
-.Ft heap_context
-argument 
-.Pq Fa ctx ,
-which also frees the entire
-.Nm heap ,
-if it is
-.No non\- Ns Dv NULL .
-The argument
-.Fa ctx
-should be
-.No non\- Ns Dv NULL .
-.Pp
-The 
-.Fn heap_insert
-function is used to insert the new heap element
-.Fa elt
-into the appropriate place (priority\-wise) in the
-.Ft heap
-indicated by 
-.Fa ctx
-(a pointer to a
-.Ft heap_context ) .
-If 
-.No non\- Ns Dv NULL ,
-the user-defined
-.Ft higher_priority
-function pointer associated with the indicated 
-.Nm heap
-is used to determine that
-.Dq appropriate place ;
-the highest\-priority elements are at the front of the queue (top of
-the heap).
-(See the description of 
-.Fn heap_new , 
-above, for more information.)
-.Pp
-The function
-.Fn heap_delete
-is used to delete the 
-.Fa i\- Ns th
-element of the queue (heap), and fixing up the queue (heap) from that
-element onward via the priority as determined by the user function
-pointed to by
-.Ft higher_priority 
-function pointer
-(see description of
-.Fn heap_new ,
-above).
-.Pp
-.Fn heap_increased
-.Pp
-.Fn heap_decreased
-.Pp
-The 
-.Fn heap_element
-function returns the
-.Fa i\- Ns th
-element of the queue/heap indicated by
-.Fa ctx ,
-if possible.
-.Pp
-The
-.Fn heap_for_each
-function provides a mechanism for the user to increment through the entire
-queue (heap) and perform some
-.Fa action 
-upon each of the queue elements.  This
-.Fa action 
-is pointer to a user\-defined function with two arguments, the first of
-which should be interpreted by the user's function as a heap element.  The 
-second value passed to the user function is just the
-.Fa uap
-argument to 
-.Fn heap_for_each ;
-this allows the user to specify additional arguments, if necessary, to
-the function pointed to by 
-.Fa action .

-.Sh DESCRIPTION
-The
-.Sy ISC
-.Nm logging library
-is flexible logging system which is based upon a set of concepts:
-.Nm logging channels ,
-.Nm categories ,
-and 
-.Nm logging contexts .
-.Pp
-The basic building block is the
-.Dq Nm logging channel , 
-which includes a 
-.Nm priority 
-(logging level), which type of logging is to occur, and other
-flags and information associated with technical aspects of the logging.  
-The set of priorities which are supported is shown below, in the section
-.Sx Message Priorities .
-A priority sets a threshold for message logging; a logging channel will
-.Em only
-log those messages which are 
-.Em at least as important
-as its priority indicates.  (The fact that 
-.Dq more important
-means 
-.Dq more negative ,
-under the current scheme, is an implementation detail; if a channel has
-a priority of
-.Dv log_error ,
-then it will
-.Em not
-log messages with the
-.Dv log_warning
-priority, but it
-.Em will
-log messages with the
-.Dv log_error
-or 
-.Dv log_critical
-priority.)
-.Pp
-The
-.Nm logging channel
-also has an indication of the type of logging performed.  Currently, 
-the supported
-.Nm logging types 
-include (see also 
-.Sx Logging Types ,
-below):
-.Bl -tag -width "log_syslog" -compact -offset indent
-.It Dv log_syslog
-for 
-.Xr syslog 3 Ns -style
-logging
-.It Dv log_file
-for use of a file
-.It Dv log_null
-for 
-.Em no
-logging
-.El
-A new logging channel is created by calling either
-.Fn log_new_syslog_channel ,
-.Fn log_new_file_channel ,
-or
-.Fn log_new_null_channel ,
-respectively.  
-When a channel is no longer to be used, it can be freed using
-.Fn log_free_channel .
-.Pp
-Both 
-.Dv log_syslog
-and
-.Dv log_file
-channel types can include more information; for instance, a
-.Dv log_syslog Ns -type 
-channel allows the specification of a 
-.Xr syslog 3 Ns -style
-.Dq facility , 
-and a
-.Dv log_file Ns -type
-channels allows the caller to set a maximum file size and number
-of versions.  (See 
-.Fn log_new_syslog_channel
-or
-.Fn log_new_file_channel ,
-below.)
-Additionally, once a logging channel of type
-.Dv log_file
-is defined, the functions
-.Fn log_open_stream
-and 
-.Fn log_close_stream
-can open or close the stream associated with the logging channel's logging
-filename.  The
-.Fn log_get_stream
-and
-.Fn log_get_filename
-functions return the stream or filename, respectively, of such a logging 
-channel.  Also unique to logging channels of type
-.Dv log_file
-is the
-.Fn log_set_file_owner
-function, which tells the logging system what user and group ought to own
-newly created files (which is only effective if the caller is privileged.)
-.Pp
-Callers provide
-.Dq Nm categories ,
-determining both the number of such categories and any (optional) names.
-Categories are like array indexes in C; if the caller declares 
-.Dq Va n
-categories, then they are considered to run from 0 to
-.Va n-1 ;
-with this scheme, a category number would be invalid if it were negative or 
-greater than/equal to 
-.Va n .
-Each category can have its own list of 
-.Nm logging channels 
-associated with it; we say that such a channel is 
-.Dq in 
-the particular category.
-.Sy NOTE :
-Individual logging channels can appear in more than one category.
-.Pp
-A
-.Dq Nm logging context
-is the set of all 
-.Nm logging channels 
-associated with the context's
-.Nm categories ;
-thus, a particular 
-.Nm category 
-scheme is associated with a particular
-.Nm logging context .
-.Sy NOTE :
-A logging channel may appear in more than one logging context, and in 
-multiple categories within each logging context.
-.Pp
-Use 
-.Fn log_add_channel
-and
-.Fn log_remove_channel
-to add or remove a logging channel to some category in a logging context.
-To see if a given category in a logging context is being used, use the
-Boolean test
-.Fn log_category_is_active .
-.Pp
-A 
-.Nm logging context
-can also have a 
-.Nm priority
-(logging level)
-and various flags associated with the whole context; in order to alter the
-flags or change the priority of a context, use
-.Fn log_option .
-.Ss Message Priorities
-Currently, five 
-.Nm priorities
-(logging levels) are supported (they can also be found in the header file):
-.Bd -literal -offset indent
-#define log_critical            (-5)
-#define log_error               (-4)
-#define log_warning             (-3)
-#define log_notice              (-2)
-#define log_info                (-1)
-.Ed
-.Pp
-In the current implementation, logging messages which have a level greater
-than 0 are considered to be debugging messages.
-.Ss Logging Types
-The three different
-.Nm logging types 
-currently supported are different values of the enumerated type
-.Ft log_output_type 
-(these are also listed in the header file): 
-.Bd -literal -offset indent
-typedef enum { log_syslog, log_file, log_null } log_output_type;
-.Ed
-.Ss Logging Channel Flags 
-There are several flags which can be set on a logging channel; the flags 
-and their meanings are as follows (they are also found in the header file):
-.Bl -tag -width "LOG_USE_CONTEXT_LEVEL  " -offset indent
-.It Dv LOG_CHANNEL_BROKEN
-This is set only when some portion of 
-.Fn log_open_stream
-fails:
-.Xr open 2 
-or
-.Xr fdopen 3  
-fail;
-.Xr stat 2
-fails in a
-.Dq bad
-way; versioning or truncation is requested on a non-normal file.
-.It Dv LOG_CHANNEL_OFF
-This is set for channels opened by 
-.Fn log_new_null_channel .
-.It Dv LOG_CLOSE_STREAM
-If this flag is set, then 
-.Fn log_free_channel
-will free a 
-.No non- Dv NULL
-stream of a logging channel which is being
-.Xr free 3 Ns -d 
-(if the logging channel is of type
-.Dv log_file ,
-of course).
-.It Dv LOG_PRINT_CATEGORY
-If set, 
-.Fn log_vwrite
-will insert the category name, if available, into logging messages which are 
-logged to channels of type
-.Dv log_syslog
-or 
-.Dv log_file .
-.It Dv LOG_PRINT_LEVEL
-If set, 
-.Fn log_vwrite
-will insert a string identifying the message priority level into the 
-information logged to channels of type
-.Dv log_syslog
-or 
-.Dv log_file .
-.It Dv LOG_REQUIRE_DEBUG
-Only log debugging messages (i.e., those with a priority greater than zero).
-.It Dv LOG_TIMESTAMP
-If set, 
-.Fn log_vwrite
-will insert a timestamp into logging messages which are logged to channels of
-type
-.Dv log_syslog
-or 
-.Dv log_file .
-.It Dv LOG_TRUNCATE
-Truncate logging file when re-opened
-.Fn ( log_open_stream 
-will
-.Xr unlink 2
-the file and then 
-.Xr open 2
-a new file of the same name with the
-.Dv O_EXCL
-bit set).
-.It Dv LOG_USE_CONTEXT_LEVEL
-Use the logging context's priority or logging level, rather than the logging 
-channel's own priority.  This can be useful for those channels which are 
-included in multiple logging contexts.
-.El
-.Ss FUNCTION DESCRIPTIONS
-The function
-.Fn log_open_stream 
-is for use with channels which log to a file; i.e., logging channels with a
-.Va type 
-field set to
-.Dq Dv log_file .
-If the logging channel pointed to by 
-.Dq Fa chan
-is valid, it attempts to open (and return) the stream associated with that
-channel.  If the stream is already opened, then it is returned; otherwise,
-.Xr stat 2
-is used to test the filename for the stream.
-.Pp
-At this point, if the logging file is supposed to have different
-.Va versions 
-(i.e., incremented version numbers; higher numbers indicate older versions
-of the logging file).  If so, then any existing versions are
-.Xr rename 2 Ns -d
-to have one version-number higher than previously, and the
-.Dq current
-filename for the stream is set to the
-.Dq \&.0
-form of the name.  Next, if the logging file is supposed to be truncated
-(i.e., the
-.Dv LOG_TRUNCATE
-bit of the
-.Va flags
-field of the logging channel structure is set), then any file with the
-.Dq current
-filename for the stream is
-.Xr unlink 2 Ns -d .
-.Sy NOTE :
-If the logging file is 
-.Em not 
-a regular file, and either of the above operations (version numbering
-or truncation) is supposed to take place, a
-.Dv NULL
-file pointer is returned.
-.Pp
-Finally, the filename associated with the logging channel is
-.Xr open 2 Ns -d
-using the appropriate flags and a mode which sets the read/write permissions
-for the user, group, and others.  The file descriptor returned by 
-.Xr open 2
-is then passed to
-.Xr fopen 3 ,
-with the append mode set, and the stream returned by this call is stored
-in the 
-.Fa chan
-structure and returned.
-.Pp
-If 
-.Fn log_open_stream
-fails at any point, then the 
-.Dv LOG_CHANNEL_BROKEN 
-bit of the
-.Va flags 
-field of the logging channel pointed to by
-.Fa chan
-is set, a 
-.Dv NULL
-is returned, and 
-.Va errno
-contains pertinent information.
-.Pp
-The
-.Fn log_close_stream
-function closes the stream associated with the logging channel pointed to by
-.Dq Fa chan 
-(if
-.Fa chan 
-is valid and the stream exists and can be closed properly by
-.Xr fclose 3 ) .  
-The stream is set to 
-.Dv NULL
-even if the call to 
-.Xr fclose 3
-fails.
-.Pp
-The function
-.Fn log_get_stream
-returns the stream associated with the logging channel pointed to by
-.Dq Fa chan ,
-if it is 
-.No non- Ns Dv NULL
-and specifies a logging channel which has a 
-.Dv FILE *
-or stream associated with it.
-.Pp
-The
-.Fn log_get_filename
-function returns the name of the file associated with the logging channel 
-pointed to by
-.Dq Fa chan ,
-if it is 
-.No non- Ns Dv NULL
-and specifies a logging channel which has a file associated with it.
-.Pp
-The
-.Fn log_vwrite 
-function performs the actual logging of a message to the various logging
-channels of a logging context
-.Fa lc .
-The message consists of an
-.Xr fprint 3 Ns -style
-.Fa format 
-and its associated
-.Fa args 
-(if any); it will be written to all logging channels in the given
-.Fa category
-which have a priority set to
-.Fa level
-or any 
-.Em less important
-priority value.  If the
-.Fa category
-is not valid or has no logging channels, then the category defaults to 0.
-.Pp
-There are a number of conditions under which a call to 
-.Fn log_vwrite
-will not result in actually logging the message: if there is no logging channel 
-at even the default category (0), or if a given channel is either 
-.Dq broken
-or
-.Dq off
-(i.e., its flags have 
-.Dv LOG_CHANNEL_BROKEN
-or
-.Dv LOG_CHANNEL_OFF
-set, respectively), or if the logging channel channel is of type
-.Dv log_null .
-Additionally, if the logging channel's flag has
-.Dv LOG_REQUIRE_DEBUG
-set and the message is not a debugging message (i.e., has a level greater
-than 0), then it will not be logged.
-Finally, if the message's priority is less important than the
-channel's logging level (the priority threshold), will not be logged.
-.Sy NOTE :
-If a logging channel's flag has
-.Dv LOG_USE_CONTEXT_LEVEL
-set, it will use the logging context's priority, rather than its own.
-.Pp
-If all of these hurdles are passed, then only
-.Dv log_syslog
-and
-.Dv log_file
-channels actually can have logging.  For channels which use
-.Xr syslog 3 ,
-the channel's 
-.Xr syslog 3
-facility is used in conjunction with a potentially modified form of the
-message's priority level, since 
-.Xr syslog 3
-has its own system of priorities
-.Pq Pa /usr/include/syslog.h . 
-All debug messages (priority >= 0) are mapped to 
-.Xr syslog 3 Ns 's
-.Dv LOG_DEBUG
-priority, all messages 
-.Dq more important
-than
-.Dv log_critical
-are mapped to
-.Dv LOG_CRIT ,
-and the priorities corresponding to the ones listed in the section
-.Sx Message Priorities
-are given the obvious corresponding 
-.Xr syslog 3
-priority.
-.Pp
-For 
-.Dv log_file
-type logging channels, if the file size is greater than the maximum file 
-size, then no logging occurs.  (The same thing happens if a 
-.Dv NULL
-stream is encountered and
-.Fn log_open_stream
-fails to open the channel's stream.)
-.Pp
-For both logging to normal files and logging via
-.Xr syslog 3 ,
-the value of the flags
-.Dv LOG_TIMESTAMP ,
-.Dv LOG_PRINT_CATEGORY , 
-and
-.Dv LOG_PRINT_LEVEL 
-are used in determining whether or not these items are included in the logged 
-information.
-.Pp
-The 
-.Fn log_write 
-function is merely a front-end to a call to 
-.Fn log_vwrite ;
-see the description of that function, above, for more information.
-.Pp
-.Fn log_check
-and
-.Fn log_check_channel
-are used to see if a contemplated logging call will actually generate any
-output, which is useful when creating a log message involves non-trivial
-work.
-.Fn log_check
-will return non-zero if a call to
-.Fn log_vwrite
-with the given 
-.Fa category
-and
-.Fa level
-would generate output on any channels, and zero otherwise.
-.Fn log_check_channel
-will return non-zero if writing to the
-.Fa chan
-at the given
-.Fa level
-would generate output.
-.Pp
-The function
-.Fn log_new_context 
-creates a new 
-.Nm logging context ,
-and stores this in the
-.Dq Va opaque
-field of the argument
-.Dq Fa lc , 
-and opaque structure used internally.  This new 
-.Nm context 
-will include the
-.Dq Fa num_categories
-and
-.Dq Fa category_names
-which are supplied; the latter can be
-.Dv NULL .
-.Sy NOTE :
-Since 
-.Dq Fa category_names
-is used directly, it 
-.Em must not 
-be freed by the caller, if it is 
-.No non- Ns Dv NULL .
-The initial logging flags and priority are both set to zero.
-.Pp
-The
-.Fn log_free_context 
-function is used to free the opaque structure 
-.Dq Va lc.opaque
-and its components.
-.Sy NOTE :
-The
-.Dq Va opaque
-field of 
-.Dq Fa lc
-.Em must 
-be
-.No non- Ns Dv NULL .
-For each of the various
-.Dq categories
-(indicated by the
-.Dq Va num_categories
-which were in the corresponding call to
-.Fn log_new_context ) 
-associated with the given 
-.Nm logging context ,
-.Em all 
-of the 
-.Nm logging channels
-are 
-.Xr free 3 Ns -d .
-The opaque structure itself is then
-.Xr free 3 Ns -d ,
-and 
-.Dq Va lc.opaque
-is set to
-.Dv NULL .
-.Pp
-.Sy NOTE :
-The function 
-.Fn log_free_context 
-does
-.Em not
-free the memory associated with 
-.Fa category_names ,
-since the logging library did not allocate the memory for it, originally;
-it was supplied in the call to
-.Fn log_new_context .
-.Pp
-The function
-.Fn log_add_channel 
-adds the 
-.Nm logging channel
-.Dq Fa chan
-to the list of logging channels in the given 
-.Fa category
-of the 
-.Nm logging context
-.Dq Fa lc .
-No checking is performed to see whether or not
-.Fa chan
-is already present in the given
-.Fa category ,
-so multiple instances in a single 
-.Fa category 
-can occur (but see
-.Fn log_remove_channel ,
-below).
-.Pp
-The
-.Fn log_remove_channel 
-function
-removes 
-.Em all
-occurrences of the
-.Nm logging channel
-.Dq Fa chan
-from the list of logging channels in the given 
-.Fa category
-of the 
-.Nm logging context
-.Dq Fa lc .
-It also attempts to free the channel by calling
-.Fn log_free_channel 
-(see its description, below).
-.Pp
-The
-.Fn log_option 
-function is used to change the
-.Fa option 
-of the indicated logging context
-.Fa lc
-to the given
-.Fa value .
-The 
-.Fa option
-can be either
-.Dv LOG_OPTION_LEVEL
-or
-.Dv LOG_OPTION_DEBUG ;
-in the first case, the log context's debugging level is reset to the
-indicated level.  If the
-.Fa option 
-is 
-.Dv LOG_OPTION_DEBUG , 
-then a non-zero
-.Fa value
-results in setting the debug flag of the logging context, while a zero
-.Fa value
-means that the debug flag is reset.
-.Pp
-The
-.Fn log_category_is_active 
-test returns a 1 if the given
-.Fa category
-of the indicated logging context
-.Fa lc
-has at least one logging channel, and 0, otherwise.
-.Pp
-The functions
-.Fn log_new_syslog_channel ,
-.Fn log_new_file_channel ,
-and 
-.Fn log_new_null_channel
-create a new channel of the type specified (thus, the difference in arguments);
-the 
-.Dq Va type
-field of the new
-.Do
-.Ft struct log_channel
-.Dc
-is always set to the appropriate value.
-.Pp
-The 
-.Fn log_new_syslog_channel
-function 
-.Xr malloc 3 Ns -s
-a new
-.Ft struct log_channel
-of
-.Va type
-.Dv log_syslog ,
-i.e., a logging channel which will use
-.Xr syslog 3 .
-The new structure is filled out with the 
-.Dq Fa flags ,
-.Dq Fa level , 
-and 
-.Dq Fa facility 
-which are given; the 
-.Va references
-field is initialized to zero.
-See 
-.Sx Logging Channel Flags
-and
-.Sx Message Priorities ,
-above, or the header file for information about acceptable values for
-.Dq Fa flags ,
-and 
-.Dq Fa level .
-The
-.Dq Fa facility .

-.Fn memput "void *mem" "size_t size"
-.Ft void 
-.Fn memstats "FILE *out"
-.Sh DESCRIPTION
-These functions access a memory management system which allows callers to not 
-fragment memory to the extent which can ordinarily occur through many random 
-calls to
-.Xr malloc 3 .
-Instead, 
-.Fn memget
-gets a large contiguous chunk of blocks of the requested 
-.Fa size 
-and parcels out these blocks as requested.  The symmetric call is
-.Fn memput ,
-which callers use to return a piece of memory obtained from
-.Fn memget .
-Statistics about memory usage are returned by
-.Fn memstats , 
-which prints a report on the stream
-.Fa out .
-.Ss INTERNALS
-Internally, linked lists of free memory blocks are stored in an array.
-The size of this array is determined by the value
-.Dv MEM_FREECOUNT ,
-currently set to 1100.  In general, for any requested blocksize
-.Dq Fa size ,
-any free blocks will be stored on the linked list at that index.
-No free lists are managed for blocks greater than or equal to
-.Dv MEM_FREECOUNT
-bytes; instead, calls to
-.Xr malloc 3
-or
-.Xr free 3
-are made, directly.
-.Pp
-Since the blocks are actually stored as linked lists, they must at least
-be large enough to hold a pointer to the next block.  This size, which is
-.Dv SMALL_SIZE_LIMIT ,
-is currently defined as
-.Bd -literal -offset indent
-#define SMALL_SIZE_LIMIT sizeof(struct { void *next; })
-.Ed
-.Pp
-Both 
-.Fn memget
-and
-.Fn memput
-enforce this limit; for example, any call to 
-.Fn memget 
-requesting a block smaller than
-.Dv SMALL_SIZE_LIMIT
-bytes will actually be considered to be of size
-.Dv SMALL_SIZE_LIMIT 
-internally.  (Such a caller request will be logged for 
-.Fn memstats
-purposes using the caller-requested
-.Fa size ;
-see the discussion of
-.Fn memstats ,
-below, for more information.)
-.Pp
-Additionally, the requested
-.Fa size
-will be adjusted so that when a large 
-.Xr malloc 3 Ns No -d
-chunk of memory is broken up into a linked list, the blocks will all fall on
-the correct memory alignment boundaries.  Thus, one can conceptualize a call
-which mentions
-.Fa size
-as resulting in a
-.Fa new_size
-which is used internally.
-.Pp
-In order to more efficiently allocate memory, there is a 
-.Dq target
-size for calls to 
-.Xr malloc 3 .
-It is given by the pre-defined value
-.Dv MEM_TARGET , 
-which is currently 4096 bytes.
-For any requested block
-.Fa size ,
-enough memory is 
-.Xr malloc 3 Ns No -d
-in order to fill up a block of about
-.Dv MEM_TARGET
-bytes.  
-.No [ Ns Sy NOTE :
-For allocations larger than
-.Dv MEM_TARGET Ns No /2
-bytes, there is a 
-.Dq fudge factor
-introduced which boosts the target size by 25% of
-.Dv MEM_TARGET .
-This means that enough memory for two blocks
-will actually be allocated for any 
-.Fa size
-such that
-.Pq Dv MEM_TARGET Ns No / 3 
-.No < Fa size No < 
-.Pq Dv MEM_TARGET Ns No *5/8 ,
-provided that the value of
-.Dv MEM_FREECOUNT 
-is at least as large as the upper limit shown above.]
-.Pp
-.Ss FUNCTION DESCRIPTIONS
-.Pp
-The function
-.Fn memget
-returns a pointer to a block of memory of at least the requested
-.Fa size .
-After adjusting
-.Fa size
-to the value
-.Va new_size
-as mentioned above in the 
-.Sx INTERNALS
-subsection, the internal array of free lists is checked.
-If there is no block of the needed
-.Va new_size ,
-then
-.Fn memget 
-will 
-.Xr malloc 3
-a chunk of memory which is as many times as 
-.Va new_size
-will fit into the target size.  This memory is then turned into a linked list 
-of 
-.Va new_size Ns No -sized
-blocks which are given out as requested; the last such block is the first one 
-returned by 
-.Fn memget .
-If the requested
-.Fa size
-is zero or negative, then 
-.Dv NULL
-is returned and
-.Va errno
-is set to
-.Dv EINVAL ;
-if 
-.Fa size
-is larger than or equal to the pre-defined maximum size
-.Dv MEM_FREECOUNT ,
-then only a single block of exactly 
-.Fa size
-will be
-.Xr malloc 3 Ns No -d
-and returned.
-.Pp
-The
-.Fn memput
-call is used to return memory once the caller is finished with it.
-After adjusting
-.Fa size
-the the value
-.Va new_size
-as mentioned in the 
-.Sx INTERNALS 
-subsection, above, the block is placed at the head of the free list of 
-.Va new_size Ns -sized
-blocks.
-If the given
-.Fa size
-is zero or negative, then 
-.Va errno
-is set to
-.Dv EINVAL ,
-as for
-.Fn memget .
-If 
-.Fa size
-is larger than or equal to the pre-defined maximum size
-.Dv MEM_FREECOUNT ,
-then the block is immediately
-.Xr free 3 Ns No -d .
-.Pp
-.Sy NOTE :
-It is important that callers give 
-.Fn memput
-.Em only
-blocks of memory which were previously obtained from
-.Fn memget 
-if the block is 
-.Em actually 
-less than
-.Dv SMALL_SIZE_LIMIT
-bytes in size.  Since all blocks will be added to a free list, any block 
-which is not at least
-.Dv SMALL_SIZE_LIMIT
-bytes long will not be able to hold a pointer to the next block in the
-free list.
-.Pp
-The
-.Fn memstats
-function will summarize the number of calls to 
-.Fn memget
-and
-.Fn memput
-for any block size from 1 byte up to
-.Pq Dv MEM_FREECOUNT No - 1  
-bytes, followed by a single line for any calls using a 
-.Fa size
-greater than or equal to 
-.Dv MEM_FREECOUNT ; 
-a brief header with shell-style comment lines prefaces the report and
-explains the information.  The 
-.Dv FILE 
-pointer
-.Fa out
-identifies the stream which is used for this report.  Currently, 
-.Fn memstat
-reports the number of calls to 
-.Fn memget
-and
-.Fn memput
-using the caller-supplied value 
-.Fa size ; 
-the percentage of outstanding blocks of a given size (i.e., the percentage
-by which calls to
-.Fn memget
-exceed 
-.Fn memput )
-are also reported on the line for blocks of the given
-.Fa size .
-However, the percent of blocks used is computed using the number of 
-blocks allocated according to the internal parameter
-.Va new_size ;
-it is the percentage of blocks used to those available at a given
-.Va new_size ,
-and is computed using the
-.Em total
-number of caller 
-.Dq gets
-for any caller
-.Fa size Ns No -s
-which map to the internally-computed
-.Va new_size .
-Keep in mind that
-.Va new_size
-is generally 
-.Em not
-equal to
-.Fa size , 
-which has these implications:
-.Bl -enum -offset indent
-.It
-For
-.Fa size
-smaller than
-.Dv SMALL_SIZE_LIMIT ,
-.Fn memstat
-.Em will 
-show statistics for caller requests under
-.Fa size , 
-but "percent used" information about such blocks will be reported under
-.Dv SMALL_SIZE_LIMIT Ns No -sized
-blocks.  
-.It
-As a general case of point 1, internal statistics are reported on the the
-line corresponding to
-.Va new_size ,
-so that, for a given caller-supplied
-.Fa size ,
-the associated internal information will appear on that line or on the next
-line which shows "percent used" information.
-.El
-.Pp
-.Sy NOTE :
-If the caller returns blocks of a given
-.Fa size
-and requests others of 
-.Fa size Ns No -s 
-which map to the same internal
-.Va new_size ,
-it is possible for
-.Fn memstats
-to report usage of greater than 100% for blocks of size
-.Va new_size .
-This should be viewed as A Good Thing.
-.Sh RETURN VALUES
-The function
-.Fn memget
-returns a 
-.No non- Ns Dv NULL
-pointer to a block of memory of the requested
-.Fa size .
-It returns
-.Dv NULL
-if either the
-.Fa size
-is invalid (less than or equal to zero) or a 
-.Xr malloc 3
-of a new block of memory fails.  In the former case, 
-.Va errno
-is set to 
-.Dv EINVAL ; 
-in the latter, it is set to
-.Dv ENOMEM .
-.Pp
-Neither
-.Fn memput
-nor
-.Fn memstats
-return a value.

-.Nm tree_init ,

-.Sh SYNOPSIS
-.Ft void
-.Fn tree_init "void **tree"
-.Ft void *
-.Fn tree_srch "void **tree" "int (*compare)()" "void *data"
-.Ft void
-.Fn tree_add "void **tree" "int (*compare)()" \

-.Ft void
-.Fn tree_mung "void **tree" "void (*del_uar)()"
-.Sh DESCRIPTION
-These functions create and manipulate a balanced binary (AVL) tree.  Each node
-of the tree contains the expected left & right subtree pointers, a short int
-balance indicator, and a pointer to the user data.  On a 32 bit system, this
-means an overhead of 4+4+2+4 bytes per node (or, on a RISC or otherwise
-alignment constrained system with implied padding, 4+4+4+4 bytes per node).
-There is no key data type enforced by this package; a caller supplied
-compare routine is used to compare user data blocks.
-.Pp
-Balanced binary trees are very fast on searches and replacements, but have a
-moderately high cost for additions and deletions.  If your application does a
-lot more searches and replacements than it does additions and deletions, the
-balanced (AVL) binary tree is a good choice for a data structure.
-.Pp
-.Fn Tree_init
-creates an empty tree and binds it to
-.Dq Fa tree
-(which for this and all other routines in this package should be declared as
-a pointer to void or int, and passed by reference), which can then be used by
-other routines in this package.  Note that more than one
-.Dq Fa tree
-variable can exist at once; thus multiple trees can be manipulated
-simultaneously.
-.Pp
-.Fn Tree_srch
-searches a tree for a specific node and returns either
-.Fa NULL
-if no node was found, or the value of the user data pointer if the node
-was found.
-.Fn compare
-is the address of a function to compare two user data blocks.  This routine
-should work much the way 
-.Xr strcmp 3
-does; in fact,
-.Xr strcmp
-could be used if the user data was a \s-2NUL\s+2 terminated string.
-.Dq Fa Data
-is the address of a user data block to be used by
-.Fn compare
-as the search criteria.  The tree is searched for a node where
-.Fn compare
-returns 0.
-.Pp
-.Fn Tree_add
-inserts or replaces a node in the specified tree.  The tree specified by
-.Dq Fa tree
-is searched as in
-.Fn tree_srch ,
-and if a node is found to match
-.Dq Fa data ,
-then the
-.Fn del_uar
-function, if non\-\s-2NULL\s+2, is called with the address of the user data
-block for the node (this routine should deallocate any dynamic memory which
-is referenced exclusively by the node); the user data pointer for the node
-is then replaced by the value of
-.Dq Fa data .
-If no node is found to match, a new node is added (which may or may not
-cause a transparent rebalance operation), with a user data pointer equal to
-.Dq Fa data .
-A rebalance may or may not occur, depending on where the node is added
-and what the rest of the tree looks like.
-.Fn Tree_add
-will return the
-.Dq Fa data
-pointer unless catastrophe occurs in which case it will return \s-2NULL\s+2.
-.Pp
-.Fn Tree_delete
-deletes a node from
-.Dq Fa tree .
-A rebalance may or may not occur, depending on where the node is removed from
-and what the rest of the tree looks like.
-.Fn Tree_delete
-returns TRUE if a node was deleted, FALSE otherwise.
-.Pp
-.Fn Tree_trav
-traverses all of
-.Dq Fa tree ,
-calling
-.Fn trav_uar
-with the address of each user data block.  If
-.Fn trav_uar
-returns FALSE at any time,
-.Fn tree_trav
-will immediately return FALSE to its caller.  Otherwise all nodes will be 
-reached and
-.Fn tree_trav
-will return TRUE.
-.Pp
-.Fn Tree_mung
-deletes every node in
-.Dq Fa tree ,
-calling
-.Fn del_uar
-(if it is not \s-2NULL\s+2) with the user data address from each node (see
-.Fn tree_add
-and
-.Fn tree_delete
-above).  The tree is left in the same state that
-.Fn tree_init
-leaves it in \- i.e., empty.
-.Sh BUGS
-Should have a way for the caller to specify application-specific
-.Xr malloc
-and
-.Xr free
-functions to be used internally when allocating meta data.
-.Sh AUTHOR
-Paul Vixie, converted and augumented from Modula\-2 examples in
-.Dq Algorithms & Data Structures ,

- *	find enclosing zone for a <dname,class>, and some server addresses
- *
- * parameters:
- *\li	res - resolver context to work within (is modified)
- *\li	dname - domain name whose enclosing zone is desired
- *\li	class - class of dname (and its enclosing zone)
- *\li	zname - found zone name
- *\li	zsize - allocated size of zname
- *\li	addrs - found server addresses
- *\li	naddrs - max number of addrs
- *
- * return values:
- *\li	< 0 - an error occurred (check errno)
- *\li	= 0 - zname is now valid, but addrs[] wasn't changed
- *\li	> 0 - zname is now valid, and return value is number of addrs[] found
- *
- * notes:
- *\li	this function calls res_nsend() which means it depends on correctly
- *	functioning recursive nameservers (usually defined in /etc/resolv.conf
- *	or its local equivilent).
- *
- *\li	we start by asking for an SOA<dname,class>.  if we get one as an
- *	answer, that just means <dname,class> is a zone top, which is fine.
- *	more than likely we'll be told to go pound sand, in the form of a
- *	negative answer.
- *
- *\li	note that we are not prepared to deal with referrals since that would
- *	only come from authority servers and our correctly functioning local
- *	recursive server would have followed the referral and got us something
- *	more definite.
- *
- *\li	if the authority section contains an SOA, this SOA should also be the
- *	closest enclosing zone, since any intermediary zone cuts would've been
- *	returned as referrals and dealt with by our correctly functioning local
- *	recursive name server.  but an SOA in the authority section should NOT
- *	match our dname (since that would have been returned in the answer
- *	section).  an authority section SOA has to be "above" our dname.
- *
- *\li	however, since authority section SOA's were once optional, it's
- *	possible that we'll have to go hunting for the enclosing SOA by
- *	ripping labels off the front of our dname -- this is known as "doing
- *	it the hard way."
- *
- *\li	ultimately we want some server addresses, which are ideally the ones
- *	pertaining to the SOA.MNAME, but only if there is a matching NS RR.
- *	so the second phase (after we find an SOA) is to go looking for the
- *	NS RRset for that SOA's zone.
- *
- *\li	no answer section processed by this code is allowed to contain CNAME
- *	or DNAME RR's.  for the SOA query this means we strip a label and
- *	keep going.  for the NS and A queries this means we just give up.
