+/*! \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.

+/*! \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.
+
+ Table 1: The Base64 Alphabet
+
+ Value Encoding Value Encoding Value Encoding Value Encoding
+ 0 A 17 R 34 i 51 z
+ 1 B 18 S 35 j 52 0
+ 2 C 19 T 36 k 53 1
+ 3 D 20 U 37 l 54 2
+ 4 E 21 V 38 m 55 3
+ 5 F 22 W 39 n 56 4
+ 6 G 23 X 40 o 57 5
+ 7 H 24 Y 41 p 58 6
+ 8 I 25 Z 42 q 59 7
+ 9 J 26 a 43 r 60 8
+ 10 K 27 b 44 s 61 9
+ 11 L 28 c 45 t 62 +
+ 12 M 29 d 46 u 63 /
+ 13 N 30 e 47 v
+ 14 O 31 f 48 w (pad) =
+ 15 P 32 g 49 x
+ 16 Q 33 h 50 y
+
+ 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.

+.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 .

+.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

+.Nd memory allocation/deallocation system
+.Sh SYNOPSIS
+.Fd #include \&<isc/memcluster.h\&>
+.Ft void *
+.Fn memget "size_t size"
+.Ft void
+.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.]

+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.

+.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)()" \
+"void *data" "void (*del_uar)()"

+.Ft int
+.Fn tree_trav "void **tree" "int (*trav_uar)()"
+.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.

+ * 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.
