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.

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. - */ - -#include "port_before.h" - -#include <sys/types.h> -#include <sys/param.h> -#include <sys/socket.h> - -#include <net/if.h> -#include <netinet/in.h> - -#include <arpa/inet.h> -#include <arpa/nameser.h> - -#include <netdb.h> -#include <resolv.h> -#include <string.h> -#include <stdlib.h> -#include <stddef.h> -#include <ctype.h> -#include <unistd.h> -#include <stdio.h> -#include <errno.h> - -#include <stdarg.h> - -#include <irs.h> -#include <isc/assertions.h> - -#include "port_after.h" - -#include "irs_data.h" - -#define SUCCESS 0 -#define ANY 0 -#define YES 1 -#define NO 0 - -static const char in_addrany[] = { 0, 0, 0, 0 };

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. -.El -.Sh SEE ALSO -.Xr gettimeofday 2 , -.Xr select 2 , -.Xr fcntl 3 , -.Xr malloc 3 , -.Xr @INDOT@named @SYS_OPS_EXT@ , -.Xr readv 3 , -.Xr writev 3 . -.Sh BUGS -This huge man page needs to be broken up into a handful of smaller ones. -.Sh HISTORY -The -.Nm eventlib -library was designed by Paul Vixie with excellent advice from his friends -and with tips 'o the cap to the X Consortium and the implementors of DEC SRC -Modula-3. diff --git a/contrib/bind9/lib/bind/isc/eventlib_p.h b/contrib/bind9/lib/bind/isc/eventlib_p.h deleted file mode 100644 index 5896553..0000000 --- a/contrib/bind9/lib/bind/isc/eventlib_p.h +++ /dev/null @@ -1,281 +0,0 @@ -/* - * Copyright (c) 2005 by Internet Systems Consortium, Inc.

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 . -.\" The following requests should be uncommented and -.\" used where appropriate.

(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 . -can be any valid -.Xr syslog 3 -facility; see the appropriate system header file or manpage for more -information. -.Pp -.Ft log_channel -.Fn log_new_file_channel "unsigned int flags" "int level" \ - "char *name" "FILE *stream" "unsigned int versions" \ - "unsigned long max_size" -.Pp -.Fn log_new_null_channel -.Pp -The functions -.Fn log_inc_references -and -.Fn log_dec_references -increment or decrements, respectively, the -.Va references -field of the logging channel pointed to by -.Dq Fa chan , -if it is a valid channel (and if the -.Va references -field is strictly positive, in the case of -.Fn log_dec_references ) . -These functions are meant to track changes in the number of different clients -which refer to the given logging channel. -.Pp -The -.Fn log_free_channel -function frees the -field of the logging channel pointed to by -.Dq Fa chan -if there are no more outstanding references to it. If the channel uses a file, -the stream is -.Xr fclose 3 Ns -d -(if the -.Dv LOG_CLOSE_STREAM -flag is set), and the filename, if -.No non- Ns Dv NULL , -is -.Xr free 3 Ns -d -before -.Dq Fa chan -is -.Xr free 3 Ns -d . -.Pp -.\" The following requests should be uncommented and -.\" used where appropriate.

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.

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 , -Niklaus Wirth, Prentice\-Hall, ISBN 0\-13\-022005\-1. diff --git a/contrib/bind9/lib/bind/make/includes.in b/contrib/bind9/lib/bind/make/includes.in deleted file mode 100644 index d7e21cb..0000000 --- a/contrib/bind9/lib/bind/make/includes.in +++ /dev/null @@ -1,44 +0,0 @@ -# Copyright (C) 2004 Internet Systems Consortium, Inc.
