- Changelog for the c-ares project
-
-* March 5, 2010 (Daniel Stenberg)
-- Daniel Johnson provided fixes for building with the clang compiler.
-
-* March 5, 2010 (Yang Tse)
-- Added IPv6 name servers support. Implementation has been based on code,
- comments and feedback provided November and December of 2008 by Daniel
- Stenberg, Gregor Jasny, Phil Blundell and myself, December 2009 by Cedric
- Bail, and February 2010 by Jakub Hrozek on the c-ares mailing list. On
- March I reviewed all that, selected the best of each, and adjusted or
- extended parts of it to make the best fit.
-
- The external and visible result of all this is that two new functions are
- added to the external API, ares_get_servers() and ares_set_servers(), which
- becomes now the preferred way of getting and setting name servers for any
- ares channel as these support both IPv4 and IPv6 name servers.
-
- In order to not break ABI compatibility, ares_init_options() with option
- mask ARES_OPT_SERVERS and ares_save_options() may still be used in code
- which is intended to run on IPv4-only stacks. But remember that these
- functions do not support IPv6 name servers. This implies that if the user
- is capable of defining or providing an IPv6 name server, and the app is
- using ares_init_options() or ares_save_options() at some point to handle
- the name servers, the app will likely loose IPv6 name servers.
-
-* January 28, 2010 (Daniel Stenberg)
-- Tommie Gannert pointed out a silly bug in ares_process_fd() since it didn't
- check for broken connections like ares_process() did. Based on that, I
- merged the two functions into a single generic one with two front-ends.
-
-* December 29, 2009 (Yang Tse)
-- Laszlo Tamas Szabo adjusted Makefile.msvc compiler options so that where
- run-time error checks enabling compiler option /GZ was used it is replaced
- with equivalent /RTCsu for Visual Studio 2003 and newer versions. Option
- /GX is replaced with equivalent /EHsc for all versions. Also fixed socket
- data type for internal configure_socket function.
-
-* December 21, 2009 (Yang Tse)
-- Ingmar Runge noticed that Windows config-win32.h configuration file
- did not include a definition for HAVE_CLOSESOCKET which resulted in
- function close() being inappropriately used to close sockets.
-
-Version 1.7.0 (Nov 30, 2009)
-
-* November 26, 2009 (Yang Tse)
-- Larry Lansing fixed ares_parse_srv_reply to properly parse replies
- which might contain non-SRV answers, skipping over potential non-SRV
- ones such as CNAMEs.
-
-* November 23, 2009 (Yang Tse)
-- Changed naming convention for c-ares libraries built with MSVC, details
- and build instructions provided in README.msvc file.
-
-* November 22, 2009 (Yang Tse)
-- Jakub Hrozek fixed more function prototypes in man pages to sync them
- with the ones declared in ares.h
-
-- Jakub Hrozek renamed addrttl and addr6ttl structs to ares_addrttl and
- ares_addr6ttl in order to prevent name space pollution, along with
- necessary changes to code base and man pages.This change does not break
- ABI, there is no need to recompile existing applications. But existing
- applications using these structs with the old name will need source code
- adjustments when recompiled using c-ares 1.7.0.
-
-* November 21, 2009 (Yang Tse)
-- Added manifest stuff to Makefile.msvc.
-
-* November 20, 2009 (Yang Tse)
-- Fixed several function prototypes in man pages that were out of sync
- with the ones declared in ares.h. Added ares_free_data() along with
- man page. Updated ares_parse_srv_reply() and ares_parse_txt_reply()
- with changes from Jakub Hrozek making these now return linked lists
- instead of arrays, and merging the ares_free_data() adjustments.
-
-* November 10, 2009 (Yang Tse)
-- Updated MSVC 6.0 project files to match settings from Makefile.msvc.
-
-* November 9, 2009 (Yang Tse)
-- Makefile.msvc is now the reference method to build c-ares and sample
- programs with any MSVC compiler or MS Visual Studio version. If no
- option or target are specified it builds dynamic and static c-ares
- libraries in debug and release flavours and also builds all sample
- programs using each of the different c-ares libraries.
-
-* November 2, 2009 (Yang Tse)
-- Renamed c-ares setup.h to ares_setup.h
-
-* October 31, 2009 (Yang Tse)
-- Symbol hiding configure options are named now --enable-symbol-hiding
- and --disable-symbol-hiding in an attempt to make them less ambiguous.
-
-* October 30, 2009 (Yang Tse)
-- Many fixes for ares_parse_txt_reply()
-
-* October 29, 2009 (Daniel Stenberg)
-- Jakub Hrozek added ares_parse_txt_reply() for TXT parsing
-
-* October 29, 2009 (Yang Tse)
-- Updated MSVC 6.0 workspace and project files that allows building
- dynamic and static c-ares libraries in debug and release flavours.
- Additionally each of the three sample programs is built against
- each of the four possible c-ares libraries, generating all this
- a total number of 12 executables and 4 libraries.
-
-* October 28, 2009 (Yang Tse)
-- Initial step towards the ability to reduce c-ares exported symbols
- when built as a shared library based on the 'visibility' attribute
- for GNUC and Intel compilers and based on __global for Sun compilers,
- taking also in account __declspec function decoration for Win32 and
- Symbian DLL's.
-
-* October 27, 2009 (Yang Tse)
-- Fixed Pelles C Win32 target compilation issues.
-
-* October 23, 2009 (Yang Tse)
-- John Engelhart noticed an unreleased problem relative to a duplicate
- ARES_ECANCELLED error code value and missing error code description.
-
-* October 7, 2009 (Yang Tse)
-- Overhauled ares__get_hostent() Fixing out of bounds memory overwrite
- triggered with malformed /etc/hosts file. Improving parsing of /etc/hosts
- file. Validating requested address family. Ensuring that failures always
- return a NULL pointer. Adjusting header inclusions.
-
-* October 6, 2009 (Yang Tse)
-- Fix ssize_t redefinition errors on WIN64 reported by Alexey Simak.
-
-* September 29, 2009 (Yang Tse)
-- Make configure script also check if _REENTRANT definition is required to
- make errno available as a preprocessor macro.
-
-* September 7, 2009 (Yang Tse)
-- Add T_SRV portability check to ares_parse_srv_reply.c
-
-* 4 Sep 2009 (Daniel Stenberg)
-- Jakub Hrozek added ares_parse_srv_reply() for SRV parsing
-
-* 3 Aug 2009 (Daniel Stenberg)
-- Joshua Kwan fixed the init routine to fill in the defaults for stuff that
- fails to get inited by other means. This fixes a case of when the c-ares
- init fails when internet access is fone.
-
-- Timo Teras changed the reason code used in the resolve callback done when
- ares_cancel() is used, to be ARES_ECANCELLED instead of ARES_ETIMEOUT to
- better allow the callback to know what's happening.
-
-* 14 Jul 2009 (Guenter Knauf)
-- renamed generated config.h to ares_config.h to avoid any future clashes
- with config.h from other projects.
-
-* June 20 2009 (Yang Tse)
-- Refactor how libraries are checked for connect() function in configure
- script and check for connect() as it is done for other functions.
-
-* June 19 2009 (Yang Tse)
-- Make sclose() function-like macro definition used to close a socket,
- now solely based on HAVE_CLOSESOCKET and HAVE_CLOSESOCKET_CAMEL
- config file preprocessor definitions
-
-* June 18 2009 (Yang Tse)
-- Add CloseSocket camel case function check for configure script.
-
-* June 17 2009 (Yang Tse)
-- Check for socket() and closesocket() as it is done for other functions
- in configure script.
-
-* June 11 2009 (Yang Tse)
-- Modified buildconf so that when automake runs it copies missing files
- instead of symlinking them.
-
-* June 8 2009 (Yang Tse)
-- Removed buildconf.bat from release and daily snapshot archives. This
- file is only for CVS tree checkout builds.
-
-* May 26 2009 (Yang Tse)
-- Added --enable-curldebug configure option to enable and disable building
- with the low-level curl debug memory tracking 'feature' to allow decoupled
- setting from --enable-debug, allowing again to build c-ares independently
- out of the CVS tree.
-
- For the c-ares library option --enable-debug enables debug build features
- which are _not_ related with memory tracking. For the c-ares library when
- --enable-debug is given it does not enable the memory tracking feature. If
- you wish to enable the curl debug memory tracking you must use configure
- option --enable-curldebug explicitily to do so.
-
- Internally, definition of preprocessor symbol DEBUGBUILD restricts code
- which is only compiled for debug enabled builds. And symbol CURLDEBUG is
- used to differentiate code which is _only_ used for memory tracking.
-
- Make ares_init(), ares_dup() and ares_init_options() fail returning
- ARES_ENOTINITIALIZED if library initialization has not been performed
- calling ares_library_init().
-
-* May 20 2009 (Yang Tse)
-- Added ares_library_init() and ares_library_cleanup() man pages.
-
-* May 19 2009 (Yang Tse)
-- Introduced ares_library_init() and ares_library_cleanup() functions.
-
- This is an API and ABI break for Win32/64 systems. Non-Win32/64 build targets
- using c-ares 1.7.0 can still survive without calling these functions. Read all
- the details on ares_library_init(3) and ares_library_cleanup(3) man pages that
- are included.
-
- curl/libcurl 7.19.5 is fully compatible with c-ares 1.7.0 on all systems.
-
- In order to use c-ares 1.7.0 with curl/libcurl on Win32/64 systems it is
- required that curl/libcurl is 7.19.5 or newer. In other words, it is not
- possible on Win32/64 to use c-ares 1.7.0 with a curl/libcurl version less
- than 7.19.5
-
-* May 11 2009 (Daniel Stenberg)
-- Gregor Jasny made c-ares link with libtool 's -export-symbols-regex option to
- only expose functions starting with ares_.
-
-* May 7 2009 (Yang Tse)
-- Fix an m4 overquoting triggering a spurious 'AS_TR_CPP' symbol definition
- attempt in generated config.h
-
-* May 2 2009 (Yang Tse)
-- Use a build-time configured ares_socklen_t data type instead of socklen_t.
-
-* April 21 2009 (Yang Tse)
-- Moved potential inclusion of system's malloc.h and memory.h header files to
- setup_once.h. Inclusion of each header file is based on the definition of
- NEED_MALLOC_H and NEED_MEMORY_H respectively.
-
-* March 11 2009 (Yang Tse)
-- Japheth Cleaver fixed acountry.c replacing u_long with unsigned long.
-
-* February 20 2009 (Yang Tse)
-- Do not halt compilation when using VS2008 to build a Windows 2000 target.
-
-* February 3 2009 (Phil Blundell)
-- If the server returns garbage or nothing at all in response to an AAAA query,
- go on and ask for A records anyway.
-
-* January 31 2009 (Daniel Stenberg)
-- ares_gethostbyname() now accepts 'AF_UNSPEC' as a family for resolving
- either AF_INET6 or AF_INET. It works by accepting any of the looksups in the
- hosts file, and it resolves the AAAA field with a fallback to A.
-
-* January 14 2009 (Daniel Stenberg)
-- ares.h no longer uses the HAVE_STRUCT_IN6_ADDR define check, but instead it
- now declares the private struct ares_in6_addr for all systems instead of
- relying on one possibly not present in the system.
-
-* January 13 2009 (Phil Blundell)
-- ares__send_query() now varies the retry timeout pseudo-randomly to avoid
- packet storms when several queries were started at the same time.
-
-* January 11 2009 (Daniel Stenberg)
-- Phil Blundell added the internal function ares__expand_name_for_response()
- that is now used by the ares_parse_*_reply() functions instead of the
- ares_expand_name() simply to easier return ARES_EBADRESP for the cases where
- the name expansion fails as in responses that really isn't expected.
-
-Version 1.6.0 (Dec 9, 2008)
-
-* December 9 2008 (Gisle Vanem)
-
- Fixes for Win32 targets using the Watt-32 tcp/ip stack.
-
-* Dec 4 2008 (Daniel Stenberg)
-
- Gregor Jasny provided the patch that introduces ares_set_socket_callback(),
- and I edited it to also get duped by ares_dup().
-
-* Dec 3 2008 (Daniel Stenberg)
-
- API changes:
-
- I made sure the public ares_config struct looks like before and yet it
- supports the ROTATE option thanks to c-ares now storing the "optmask"
- internally. Thus we should be ABI compatible with the past release(s)
- now. My efforts mentioned below should not break backwards ABI compliance.
-
- Here's how I suggest we proceed with the API:
-
- ares_init() will be primary "channel creator" function.
-
- ares_init_options() will continue to work exactly like now and before. For
- starters, it will be the (only) way to set the existing options.
-
- ares_save_options() will continue to work like today, but will ONLY save
- options that you can set today (including ARES_OPT_ROTATE actually) but new
- options that we add may not be saved with this.
-
- Instead we introduce:
-
- ares_dup() that instead can make a new channel and clone the config used
- from an existing channel. It will then clone all config options, including
- future new things we add.
-
- ares_set_*() style functions that set (new) config options. As a start we
- simply add these for new functionality, but over time we can also introduce
- them for existing "struct ares_options" so that we can eventually deprecate
- the two ares_*_options() functions.
-
- ares_get_*() style functions for extracting info from a channel handle that
- should be used instead of ares_save_options().
-
-* Nov 26 2008 (Yang Tse)
-- Brad Spencer provided changes to allow buildconf to work on OS X.
-
-- Gerald Combs fixed a bug in ares_parse_ptr_reply() which would cause a
- buffer to shrink instead of expand if a reply contained 8 or more records.
-
-* Nov 25 2008 (Yang Tse)
-- In preparation for the upcomming IPv6 nameservers patch, the internal
- ares_addr union is now changed into an internal struct which also holds
- the address family.
-
-* Nov 19 2008 (Daniel Stenberg)
-- Brad Spencer brought the new function ares_gethostbyname_file() which simply
- resolves a host name from the given file, using the regular hosts syntax.
-
-* Nov 1 2008 (Daniel Stenberg)
-- Carlo Contavalli added support for the glibc "rotate" option, as documented
- in man resolv.conf:
-
- causes round robin selection of nameservers from among those listed. This
- has the effect of spreading the query load among all listed servers, rather
- than having all clients try the first listed server first every time.
-
- You can enable it with ARES_OPT_ROTATE
-
-* Oct 21 2008 (Yang Tse)
- Charles Hardin added handling of EINPROGRESS for UDP connects.
-
-* Oct 18 2008 (Daniel Stenberg)
- Charles Hardin made adig support a regular numerical dotted IP address for the
- -s option as well.
-
-* Oct 7 2008 (Yang Tse)
-- Added --enable-optimize configure option to enable and disable compiler
- optimizations to allow decoupled setting from --enable-debug.
-
-* Oct 2 2008 (Yang Tse)
-- Added --enable-warnings configure option to enable and disable strict
- compiler warnings to allow decoupled setting from --enable-debug.
-
-* Sep 17 2008 (Yang Tse)
-- Code reorganization to allow internal/private use of "nameser.h" to any
- system that lacks arpa/nameser.h or arpa/nameser_compat.h header files.
-
-* Sep 16 2008 (Yang Tse)
-- Code reorganization to allow internal/private use of ares_writev to any
- system that lacks the writev function.
-
-* Sep 15 2008 (Yang Tse)
-- Code reorganization to allow internal/private use of ares_strcasecmp to any
- system that lacks the strcasecmp function.
-
-- Improve configure detection of some string functions.
-
-* Sep 11 2008 (Yang Tse)
-- Code reorganization to allow internal/private use of ares_strdup to any
- system that lacks the strdup function.
-
-Version 1.5.3 (Aug 29, 2008)
-
-* Aug 25 2008 (Yang Tse)
-- Improvement by Brad House:
-
- This patch addresses an issue in which a response could be sent back to the
- source port of a client from a different address than the request was made to.
- This is one form of a DNS cache poisoning attack.
-
- The patch simply uses recvfrom() rather than recv() and validates that the
- address returned from recvfrom() matches the address of the server we have
- connected to. Only necessary on UDP sockets as they are connection-less, TCP
- is unaffected.
-
-- Fix by George Neill:
- Fixed compilation of acountry sample application failure on some systems.
-
-* Aug 4 2008 (Daniel Stenberg)
-- Fix by Tofu Linden:
-
- The symptom:
- * Users (usually, but not always) on 2-Wire routers and the Comcast service
- and a wired connection to their router would find that the second and
- subsequent DNS lookups from fresh processes using c-ares to resolve the same
- address would cause the process to never see a reply (it keeps polling for
- around 1m15s before giving up).
-
- The repro:
- * On such a machine (and yeah, it took us a lot of QA to find the systems
- that reproduce such a specific problem!), do 'ahost www.secondlife.com',
- then do it again. The first process's lookup will work, subsequent lookups
- will time-out and fail.
-
- The cause:
- * init_id_key() was calling randomize_key() *before* it initialized
- key->state, meaning that the randomness generated by randomize_key() is
- immediately overwritten with deterministic values. (/dev/urandom was also
- being read incorrectly in the c-ares version we were using, but this was
- fixed in a later version.)
- * This makes the stream of generated query-IDs from any new c-ares process
- be an identical and predictable sequence of IDs.
- * This makes the 2-Wire's default built-in DNS server detect these queries
- as probable-duplicates and (erroneously) not respond at all.
-
-
-* Aug 4 2008 (Yang Tse)
-- Autoconf 2.62 has changed the behaviour of the AC_AIX macro which we use.
- Prior versions of autoconf defined _ALL_SOURCE if _AIX was defined. 2.62
- version of AC_AIX defines _ALL_SOURCE and other four preprocessor symbols
- no matter if the system is AIX or not. To keep the traditional behaviour,
- and an uniform one across autoconf versions AC_AIX is replaced with our
- own internal macro CARES_CHECK_AIX_ALL_SOURCE.
-
-* Aug 1 2008 (Yang Tse)
-- Configure process now checks if the preprocessor _REENTRANT symbol is already
- defined. If it isn't currently defined a set of checks are performed to test
- if its definition is required to make visible to the compiler a set of *_r
- functions. Finally, if _REENTRANT is already defined or needed it takes care
- of making adjustments necessary to ensure that it is defined equally for the
- configure process tests and generated config file.
-
-* Jul 20 2008 (Yang Tse)
-- When recvfrom prototype uses a void pointer for arguments 2, 5 or 6 this will
- now cause the definition, as appropriate, of RECVFROM_TYPE_ARG2_IS_VOID,
- RECVFROM_TYPE_ARG5_IS_VOID or RECVFROM_TYPE_ARG6_IS_VOID.
-
-* Jul 17 2008 (Yang Tse)
-- RECVFROM_TYPE_ARG2, RECVFROM_TYPE_ARG5 and RECVFROM_TYPE_ARG6 are now defined
- to the data type pointed by its respective argument and not the pointer type.
-
-* Jul 16 2008 (Yang Tse)
-- Improved configure detection of number of arguments for getservbyport_r.
- Detection is now based on compilation checks instead of linker ones.
-
-- Configure process now checks availability of recvfrom() socket function and
- finds out its return type and the types of its arguments. Added definitions
- for non-configure systems config files, and introduced macro sreadfrom which
- will be used on udp sockets as a recvfrom() wrapper in the future.
-
-* Jul 15 2008 (Yang Tse)
-- Introduce definition of _REENTRANT symbol in setup.h to improve library
- usability. Previously the configure process only used the AC_SYS_LARGEFILE
- macro for debug builds, now it is also used for non-debug ones enabling the
- use of configure options --enable-largefile and --disable-largefile which
- might be needed for library compatibility. Remove checking the size of
- curl_off_t, it is no longer needed.
-
-* Jul 3 2008 (Daniel Stenberg)
-- Phil Blundell: If you ask ares_gethostbyname() to do an AF_INET6 lookup and
- the target host has only A records, it automatically falls back to an
- AF_INET lookup and gives you the A results. However, if the target host has
- a CNAME record, this behaviour is defeated since the original query does
- return some data even though ares_parse_aaa_reply() doesn't consider it
- relevant. Here's a small patch to make it behave the same with and without
- the CNAME.
-
-* Jul 2 2008 (Yang Tse)
-- Fallback to gettimeofday when monotonic clock is unavailable at run-time.
-
-* Jun 30 2008 (Daniel Stenberg)
-
-- As was pointed out to me by Andreas Schuldei, the MAXHOSTNAMELEN define is
- not posix or anything and thus c-ares failed to build on hurd (and possibly
- elsewhere). The define was also somewhat artificially used in the windows
- port. Now, I instead rewrote the use of gethostbyname to enlarge the host
- name buffer in case of need and totally avoid the use of the MAXHOSTNAMELEN
- define. I thus also removed the defien from the namser.h file where it was
- once added for the windows build.
-
- I also fixed init_by_defaults() function to not leak memory in case if
- error.
-
-* Jun 9 2008 (Yang Tse)
-
-- Make libcares.pc generated file for pkg-config include information relative
- to the libraries needed for the static linking of c-ares.
-
-* May 30 2008 (Yang Tse)
-
-- Brad House fixed a missing header file inclusion in adig sample program.
-
-Version 1.5.2 (May 29, 2008)
-
-* May 13 2008 (Daniel Stenberg)
-
-- Introducing millisecond resolution support for the timeout option. See
- ares_init_options()'s ARES_OPT_TIMEOUTMS.
-
-* May 9 2008 (Yang Tse)
-
-- Use monotonic time source if available, for private function ares__tvnow()
-
-* May 7 2008 (Daniel Stenberg)
-
-- Sebastian made c-ares able to return all PTR-records when doing reverse
- lookups. It is not common practice to have multiple PTR-Records for a single
- IP, but its perfectly legal and some sites have those.
-
-- Doug Goldstein provided a configure patch: updates autoconf 2.13 usage to
- autoconf 2.57 usage (which is the version you have specified as the minimum
- version). It's a minor change but it does clean up some warnings with newer
- autoconf (specifically 2.62).
-
-* May 5 2008 (Yang Tse)
-
-- Improved parsing of resolver configuration files.
-
-* April 4 2008 (Daniel Stenberg)
-
-- Eino Tuominen improved the code when a file is used to seed the randomizer.
-
-- Alexey Simak made adig support NAPTR records
-
-- Alexey Simak fixed the VC dsp file by adding the missing source file
- ares_expand_string.c
-
-* December 11 2007 (Gisle Vanem)
-
-- Added another sample application; acountry.c which converts an
- IPv4-address(es) and/or host-name(s) to country-name and country-code.
- This uses the service of the DNSBL at countries.nerd.dk.
-
-* December 3 2007 (Daniel Stenberg)
-
-- Brad Spencer fixed the configure script to assume that there's no
- /dev/urandom when built cross-compiled as then the script cannot check for
- it.
-
-- Erik Kline cleaned up ares_gethostbyaddr.c:next_lookup() somewhat
-
-Version 1.5.1 (Nov 21, 2007)
-
-* November 21 2007 (Daniel Stenberg)
-
-- Robin Cornelius pointed out that ares_llist.h was missing in the release
- archive for 1.5.0
-
-Version 1.5.0 (Nov 21, 2007)
-
-* October 2 2007 (Daniel Stenberg)
-
-- ares_strerror() segfaulted if the input error number was out of the currently
- supported range.
-
-- Yang Tse: Avoid a segfault when generating a DNS "Transaction ID" in
- internal function init_id_key() under low memory conditions.
-
-* September 28 2007 (Daniel Stenberg)
-
-- Bumped version to 1.5.0 for next release and soname bumped to 2 due to ABI
- and API changes in the progress callback (and possibly more coming up from
- Steinar)
-
-* September 28 2007 (Steinar H. Gunderson)
-
-- Don't skip a server if it's the only one. (Bugfix from the Google tree.)
-
-- Made the query callbacks receive the number of timeouts that happened during
- the execution of a query, and updated documentation accordingly. (Patch from
- the Google tree.)
-
-- Support a few more socket options: ARES_OPT_SOCK_SNDBUF and
- ARES_OPT_SOCK_RCVBUF
-
-- Always register for TCP events even if there are no outstanding queries, as
- the other side could always close the connection, which is a valid event
- which should be responded to.
-
-* September 22 2007 (Daniel Stenberg)
-
-- Steinar H. Gunderson fixed: Correctly clear sockets from the fd_set on in
- several functions (write_tcp_data, read_tcp_data, read_udp_packets) so that
- if it fails and the socket is closed the following code doesn't try to use
- the file descriptor.
-
-- Steinar H. Gunderson modified c-ares to now also do to DNS retries even when
- TCP is used since there are several edge cases where it still makes sense.
-
-- Brad House provided a fix for ares_save_options():
-
- Apparently I overlooked something with the ares_save_options() where it
- would try to do a malloc(0) when no options of that type needed to be saved.
- On most platforms, this was fine because malloc(0) doesn't actually return
- NULL, but on AIX it does, so ares_save_options would return ARES_ENOMEM.
-
-* July 14 2007 (Daniel Stenberg)
-
-- Vlad Dinulescu fixed two outstanding valgrind reports:
-
- 1. In ares_query.c , in find_query_by_id we compare q->qid (which is a short
- int variable) with qid, which is declared as an int variable. Moreover,
- DNS_HEADER_SET_QID is used to set the value of qid, but DNS_HEADER_SET_QID
- sets only the first two bytes of qid. I think that qid should be declared as
- "unsigned short" in this function.
-
- 2. The same problem occurs in ares_process.c, process_answer() . query->qid
- (an unsigned short integer variable) is compared with id, which is an
- integer variable. Moreover, id is initialized from DNS_HEADER_QID which sets
- only the first two bytes of id. I think that the id variable should be
- declared as "unsigned short" in this function.
-
- Even after declaring these variables as "unsigned short", the valgrind
- errors are still there. Which brings us to the third problem.
-
- 3. The third problem is that Valgrind assumes that query->qid is not
- initialised correctly. And it does that because query->qid is set from
- DNS_HEADER_QID(qbuf); Valgrind says that qbuf has unitialised bytes. And
- qbuf has uninitialised bytes because of channel->next_id . And next_id is
- set by ares_init.c:ares__generate_new_id() . I found that putting short r=0
- in this function (instead of short r) makes all Valgrind warnings go away.
- I have studied ares__rc4() too, and this is the offending line:
-
- buffer_ptr[counter] ^= state[xorIndex]; (ares_query.c:62)
-
- This is what triggers Valgrind.. buffer_ptr is unitialised in this function,
- and by applying ^= on it, it remains unitialised.
-
-Version 1.4.0 (June 8, 2007)
-
-* June 4 2007 (Daniel Stenberg)
-
-- James Bursa reported a major memory problem when resolving multi-IP names
- and I found and fixed the problem. It was added by Ashish Sharma's patch
- two days ago.
-
- When I then tried to verify multiple entries in /etc/hosts after my fix, I
- got another segfault and decided this code was not ripe for inclusion and I
- reverted the patch.
-
-* June 2 2007
-
-- Brad Spencer found and fixed three flaws in the code, found with the new
- gcc 4.2.0 warning: -Waddress
-
-- Brad House fixed VS2005 compiler warnings due to time_t being 64bit.
- He also made recent Microsoft compilers use _strdup() instead of strdup().
-
-- Brad House's man pages for ares_save_options() and ares_destroy_options()
- were added.
-
-- Ashish Sharma provided a patch for supporting multiple entries in the
- /etc/hosts file. Patch edited for coding style and functionality by me
- (Daniel).
-
-* May 30 2007
-
-- Shmulik Regev brought cryptographically secure transaction IDs:
-
- The c-ares library implementation uses a DNS "Transaction ID" field that is
- seeded with a pseudo random number (based on gettimeofday) which is
- incremented (++) between consecutive calls and is therefore rather
- predictable. In general, predictability of DNS Transaction ID is a well
- known security problem (e.g.
- http://bak.spc.org/dms/archive/dns_id_attack.txt) and makes a c-ares based
- implementation vulnerable to DNS poisoning. Credit goes to Amit Klein
- (Trusteer) for identifying this problem.
-
- The patch I wrote changes the implementation to use a more secure way of
- generating unique IDs. It starts by obtaining a key with reasonable entropy
- which is used with an RC4 stream to generate the cryptographically secure
- transaction IDs.
-
- Note that the key generation code (in ares_init:randomize_key) has two
- versions, the Windows specific one uses a cryptographically safe function
- provided (but undocumented :) by the operating system (described at
- http://blogs.msdn.com/michael_howard/archive/2005/01/14/353379.aspx). The
- default implementation is a bit naive and uses the standard 'rand'
- function. Surely a better way to generate random keys exists for other
- platforms.
-
- The patch can be tested by using the adig utility and using the '-s' option.
-
-- Brad House added ares_save_options() and ares_destroy_options() that can be
- used to keep options for later re-usal when ares_init_options() is used.
-
- Problem: Calling ares_init() for each lookup can be unnecessarily resource
- intensive. On windows, it must LoadLibrary() or search the registry
- on each call to ares_init(). On unix, it must read and parse
- multiple files to obtain the necessary configuration information. In
- a single-threaded environment, it would make sense to only
- ares_init() once, but in a heavily multi-threaded environment, it is
- undesirable to ares_init() and ares_destroy() for each thread created
- and track that.
-
- Solution: Create ares_save_options() and ares_destroy_options() functions to
- retrieve and free options obtained from an initialized channel. The
- options populated can be used to pass back into ares_init_options(),
- it should populate all needed fields and not retrieve any information
- from the system. Probably wise to destroy the cache every minute or
- so to prevent the data from becoming stale.
-
-- Daniel S added ares_process_fd() to allow applications to ask for processing
- on specific sockets and thus avoiding select() and associated
- functions/macros. This function will be used by upcoming libcurl releases
- for this very reason. It also made me export the ares_socket_t type in the
- public ares.h header file, since ares_process_fd() uses that type for two of
- the arguments.
-
-* May 25 2007
-
-- Ravi Pratap fixed a flaw in the init_by_resolv_conf() function for windows
- that could cause it to return a bad return code.
-
-* April 16 2007
-
-- Yang Tse: Provide ares_getopt() command-line parser function as a source
- code helper function, not belonging to the actual c-ares library.
-
-* February 19 2007
-
-- Vlad Dinulescu added ares_parse_ns_reply().
-
-* February 13 2007
-
-- Yang Tse: Fix failure to get the search sequence of /etc/hosts and
- DNS from /etc/nsswitch.conf, /etc/host.conf or /etc/svc.conf when
- /etc/resolv.conf did not exist or was unable to read it.
-
-* November 22 2006
-
-- Install ares_dns.h too
-
-- Michael Wallner fixed this problem: When I set domains in the options
- struct, and there are domain/search entries in /etc/resolv.conf, the domains
- of the options struct will be overridden.
-
-* November 6 2006
-
-- Yang Tse removed a couple of potential zero size memory allocations.
-
-- Andreas Rieke fixed the line endings in the areslib.dsp file that I (Daniel)
- broke in the 1.3.2 release. We should switch to a system where that file is
- auto-generated. We could rip some code for that from curl...
-
-Version 1.3.2 (November 3, 2006)
-
-* October 12 2006
-
-- Prevent ares_getsock() to overflow if more than 16 sockets are used.
-
-* September 11 2006
-
-- Guilherme Balena Versiani: I noted a strange BUG in Win32 port
- (ares_init.c/get_iphlpapi_dns_info() function): when I disable the network
- by hand or disconnect the network cable in Windows 2000 or Windows XP, my
- application gets 127.0.0.1 as the only name server. The problem comes from
- 'GetNetworkParams' function, that returns the empty string "" as the only
- name server in that case. Moreover, the Windows implementation of
- inet_addr() returns INADDR_LOOPBACK instead of INADDR_NONE.
-
-* August 29 2006
-
-- Brad Spencer did
-
- o made ares_version.h use extern "C" for c++ compilers
- o fixed compiler warnings in ares_getnameinfo.c
- o fixed a buffer position init for TCP reads
-
-* August 3 2006
-
-- Ravi Pratap fixed ares_getsock() to actually return the proper bitmap and
- not always zero!
-
-Version 1.3.1 (June 24, 2006)
-
-* July 23, 2006
-
-- Gisle Vanem added getopt() to the ahost program. Currently accepts
- only [-t {a|aaaa}] to specify address family in ares_gethostbyname().
-
-* June 19, 2006
-
-- (wahern) Removed "big endian" DNS section and RR data integer parser
- macros from ares_dns.h, which break c-ares on my Sparc64. Bit-wise
- operations in C operate on logical values. And in any event the octets are
- already in big-endian (aka network) byte order so they're being reversed
- (thus the source of the breakage).
-
-* June 18, 2006
-
-- William Ahern handles EAGAIN/EWOULDBLOCK errors in most of the I/O calls
- from area_process.c.
-
- TODO: Handle one last EAGAIN for a UDP socket send(2) in
- ares__send_query().
-
-* May 10, 2006
-
-- Bram Matthys brought my attention to a libtool peculiarity where detecting
- things such as C++ compiler actually is a bad thing and since we don't need
- that detection I added a work-around, much inspired by a previous patch by
- Paolo Bonzini. This also shortens the configure script quite a lot.
-
-* May 3, 2006
-
-- Nick Mathewson added the ARES_OPT_SOCK_STATE_CB option that when set makes
- c-ares call a callback on socket state changes. A better way than the
- ares_getsock() to get full control over the socket state.
-
-* January 9, 2006
-
-- Alexander Lazic improved the getservbyport_r() configure check.
-
-* January 6, 2006
-
-- Alexander Lazic pointed out that the buildconf should use the ACLOCAL_FLAGS
- variable for easier controlling what it does and how it runs.
-
-* January 5, 2006
-
-- James Bursa fixed c-ares to find the hosts file on RISC OS, and made it
- build with newer gcc versions that no longer defines "riscos".
-
-* December 22
-
-- Daniel Stenberg added ares_getsock() that extracts the set of sockets to
- wait for action on. Similar to ares_fds() but not restricted to using
- select() for the waiting.
-
-* November 25
-
-- Yang Tse fixed some send() / recv() compiler warnings
-
-* September 18
-
-- Added constants that will be used by ares_getaddrinfo
-
-- Made ares_getnameinfo use the reentrant getservbyport (getservbyport_r) if it
- is available to ensure it works properly in a threaded environment.
-
-* September 10
-
-- configure fix for detecting a member in the sockaddr_in6 struct which failed
- on ipv6-enabled HP-UX 11.00
-
-Version 1.3.0 (August 29, 2005)
-
-* August 21
-
-- Alfredo Tupone provided a fix for the Windows code in get_iphlpapi_dns_info()
- when getting the DNS server etc.
-
-* June 19
-
-- Added some checks for the addrinfo structure.
-
-* June 2
-
-- William Ahern:
-
- Make UDP sockets non-blocking. I've confirmed that at least on Linux 2.4 a
- read event can come back from poll() on a valid SOCK_DGRAM socket but
- recv(2) will still block. This patch doesn't ignore EAGAIN in
- read_udp_packets(), though maybe it should. (This patch was edited by Daniel
- Stenberg and a new configure test was added (imported from curl's configure)
- to properly detect what non-blocking socket approach to use.)
-
- I'm not quite sure how this was happening, but I've been seeing PTR queries
- which seem to return empty responses. At least, they were empty when calling
- ares_expand_name() on the record. Here's a patch which guarantees to
- NUL-terminate the expanded name. The old behavior failed to NUL-terminate if
- len was 0, and this was causing strlen() to run past the end of the buffer
- after calling ares_expand_name() and getting ARES_SUCCESS as the return
- value. If q is not greater than *s then it's equal and *s is always
- allocated with at least one byte.
-
-* May 16
-
-- Added ares_getnameinfo which mimics the getnameinfo API (another feature
- that could use testing).
-
-* May 14
-
-- Added an inet_ntop function from BIND for systems that do not have it.
-
-* April 9
-
-- Made sortlist support IPv6 (this can probably use some testing).
-
-- Made sortlist support CIDR matching for IPv4.
-
-* April 8
-
-- Added preliminary IPv6 support to ares_gethostbyname. Currently, sortlist
- does not work with IPv6. Also provided an implementation of bitncmp from
- BIND for systems that do not supply this function. This will be used to add
- IPv6 support to sortlist.
-
-- Made ares_gethostbyaddr support IPv6 by specifying AF_INET6 as the family.
- The function can lookup IPv6 addresses both from files (/etc/hosts) and
- DNS lookups.
-
-* April 7
-
-- Tupone Alfredo fixed includes of arpa/nameser_compat.h to build fine on Mac
- OS X.
-
-* April 5
-
-- Dominick Meglio: Provided implementations of inet_net_pton and inet_pton
- from BIND for systems that do not include these functions.
-
-* March 11, 2005
-
-- Dominick Meglio added ares_parse_aaaa_reply.c and did various
- adjustments. The first little steps towards IPv6 support!
-
-* November 7
-
-- Fixed the VC project and makefile to use ares_cancel and ares_version
-
-* October 24
-
-- The released ares_version.h from 1.2.1 says 1.2.0 due to a maketgz flaw.
- This is now fixed.
-
-Version 1.2.1 (October 20, 2004)
-
-* September 29
-
-- Henrik Stoerner fix: got a report that Tru64 Unix (the unix from Digital
- when they made Alpha's) uses /etc/svc.conf for the purpose fixed below for
- other OSes. He made c-ares check for and understand it if present.
-
-- Now c-ares will use local host name lookup _before_ DNS resolving by default
- if nothing else is told.
-
-* September 26
-
-- Henrik Stoerner: found out that c-ares does not look at the /etc/host.conf
- file to determine the sequence in which to search /etc/hosts and DNS. So on
- systems where this order is defined by /etc/host.conf instead of a "lookup"
- entry in /etc/resolv.conf, c-ares will always default to looking in DNS
- first, and /etc/hosts second.
-
- c-ares now looks at
-
- 1) resolv.conf (for the "lookup" line);
- 2) nsswitch.fon (for the "hosts:" line);
- 3) host.conf (for the "order" line).
-
- First match wins.
-
-- Dominick Meglio patched: C-ares on Windows assumed that the HOSTS file is
- located in a static location. It assumed
- C:\Windows\System32\Drivers\Etc. This is a poor assumption to make. In fact,
- the location of the HOSTS file can be changed via a registry setting.
-
- There is a key called DatabasePath which specifies the path to the HOSTS
- file:
- http://www.microsoft.com/technet/itsolutions/network/deploy/depovg/tcpip2k.mspx
-
- The patch will make c-ares correctly consult the registry for the location
- of this file.
-
-* August 29
-
-- Gisle Vanem fixed the MSVC build files.
-
-* August 20
-
-- Gisle Vanem made c-ares build and work with his Watt-32 TCP/IP stack.
-
-* August 13
-
-- Harshal Pradhan made a minor syntax change in ares_init.c to make it build
- fine with MSVC 7.1
-
-* July 24
-
-- Made the lib get built static only if --enable-debug is used.
-
-- Gisle Vanem fixed:
-
- Basically in loops like handle_errors(), 'query->next' was assigned a local
- variable and then query was referenced after the memory was freed by
- next_server(). I've changed that so next_server() and end_query() returns
- the next query. So callers should use this ret-value.
-
- The next problem was that 'server->tcp_buffer_pos' had a random value at
- entry to 1st recv() (luckily causing Winsock to return ENOBUFS).
-
- I've also added a ares_writev() for Windows to streamline the code a bit
- more.
-
-* July 20
-- Fixed a few variable return types for some system calls. Made configure
- check for ssize_t to make it possible to use that when receiving the send()
- error code. This is necessary to prevent compiler warnings on some systems.
-
-- Made configure create config.h, and all source files now include setup.h that
- might include the proper config.h (or a handicrafted alternative).
-
-- Switched to 'ares_socket_t' type for sockets in ares, since Windows don't
- use 'int' for that.
-
-- automake-ified and libool-ified c-ares. Now it builds libcares as a shared
- lib on most platforms if wanted. (This bloated the size of the release
- archive with another 200K!)
-
-- Makefile.am now uses Makefile.inc for the c sources, h headers and man
- pages, to make it easier for other makefiles to use the exact same set of
- files.
-
-- Adjusted 'maketgz' to use the new automake magic when building distribution
- archives.
-
-- Anyone desires HTML and/or PDF versions of the man pages in the release
- archives?
-
-* July 3
-- Günter Knauf made c-ares build and run on Novell Netware.
-
-* July 1
-- Gisle Vanem provided Makefile.dj to build with djgpp, added a few more djgpp
- fixes and made ares not use 'errno' to provide further info on Windows.
-
-* June 30
-- Gisle Vanem made it build with djgpp and run fine with the Watt-32 stack.
-
-* June 10
-- Gisle Vanem's init patch for Windows:
-
- The init_by_resolv_conf() function fetches the DNS-server(s)
- from a series of registry branches.
-
- This can be wrong in the case where DHCP has assigned nameservers, but the
- user has overridden these servers with other prefered settings. Then it's
- wrong to use the DHCPNAMESERVER setting in registry.
-
- In the case of no global DHCP-assigned or fixed servers, but DNS server(s)
- per adapter, one has to query the adapter branches. But how can c-ares know
- which adapter is valid for use? AFAICS it can't. There could be one adapter
- that is down (e.g. a VPN adapter).
-
- So it's better to leave this to the IP Helper API (iphlapi) available in
- Win-98/2000 and later. My patch falls-back to the old way if not available.
-
-* June 8
-- James Bursa fixed an init issue for RISC OS.
-
-* May 11
-- Nico Stappenbelt reported that when processing domain and search lines in
- the resolv.conf file, the first entry encountered is processed and used as
- the search list. According to the manual pages for both Linux, Solaris and
- Tru64, the last entry of either a domain or a search field is used.
-
- This is now adjusted in the code
-
-Version 1.2.0 (April 13, 2004)
-
-* April 2, 2004
-- Updated various man pages to look nicer when converted to HTML on the web
- site.
-
-* April 1, 2004
-- Dirk Manske provided a new function that is now named ares_cancel(). It is
- used to cancel/cleanup a resolve/request made using ares functions on the
- given ares channel. It does not destroy/kill the ares channel itself.
-
-- Dominick Meglio cleaned up the formatting in several man pages.
-
-* March 30, 2004
-- Dominick Meglio's new ares_expand_string. A helper function when decoding
- incoming DNS packages.
-
-- Daniel Stenberg modified the Makefile.in to use a for loop for the man page
- installation to improve overview and make it easier to add man pages.
-
-Version 1.1.0 (March 11, 2004)
-
-* March 9, 2004
-- Gisle Vanem improved build on Windows.
-
-* February 25, 2004
-- Dan Fandrich found a flaw in the Feb 22 fix.
-
-- Added better configure --enable-debug logic (taken from the curl configure
- script). Added acinclude.m4 to the tarball.
-
-* February 23, 2004
-- Removed ares_free_errmem(), the function, the file and the man page. It was
- not used and it did nothing.
-
-- Fixed a lot of code that wasn't "64bit clean" and thus caused a lot of
- compiler warnings on picky compilers.
-
-* February 22, 2004
-- Dominick Meglio made ares init support multiple name servers in the
- NameServer key on Windows.
-
-* February 16, 2004
-- Modified ares_private.h to include libcurl's memory debug header if
- CURLDEBUG is set. This makes all the ares-functions supervised properly by
- the curl test suite. This also forced me to add inclusion of the
- ares_private.h header in a few more files that are using some kind of
- memory-related resources.
-
-- Made the makefile only build ahost and adig if 'make demos' is used.
-
-* February 10, 2004
-- Dirk Manske made ares_version.h installed with 'make install'
-
-* February 4, 2004
-- ares_free_errmem() is subject for removal, it is simply present for future
- purposes, and since we removed the extra parameter in strerror() it won't
- be used by c-ares!
-- configure --enable-debug now enables picky compiler options if gcc is used
-- fixed several compiler warnings --enable-debug showed and Joerg Mueller-Tolk
- reported
-
-Version 1.0.0 (February 3, 2004)
-
-* February 3, 2004
-- now we produce the libcares.a library instead of the previous libares.a
- since we are no longer compatible
-
-* February 2, 2004
-
-- ares_strerror() has one argument less. This is the first official
- modification of the existing provided ares API.
-
-* January 29, 2004
-
-- Dirk Manske fixed how the socket is set non-blocking.
-
-* January 4, 2004
-
-- Dominick Meglio made the private gettimeofday() become ares_gettimeofday()
- instead in order to not pollute the name space and risk colliding with
- other libraries' versions of this function.
-
-* October 24, 2003. Daniel Stenberg
-
- Added ares_version().
-
-Version 1.0-pre1 (8 October 2003)
-
-- James Bursa made it run on RISC OS
-
-- Dominick Meglio made it run fine on NT4
-
-- Duncan Wilcox made it work fine on Mac OS X
-
-- Daniel Stenberg adjusted the windows port
-
-- liren at vivisimo.com made the initial windows port

-#
-# 1.Start with version information of 0:0:0 for each libtool library.
-#
-# 2.Update the version information only immediately before a public release of
-# your software. More frequent updates are unnecessary, and only guarantee
-# that the current interface number gets larger faster.
-#
-# 3.If the library source code has changed at all since the last update, then
-# increment revision (c:r+1:a)
-#
-# 4.If any interfaces have been added, removed, or changed since the last
-# update, increment current, and set revision to 0. (c+1:r=0:a)
-#
-# 5.If any interfaces have been added since the last public release, then
-# increment age. (c:r:a+1)
-#
-# 6.If any interfaces have been removed since the last public release, then
-# set age to 0. (c:r:a=0)

-Major changes since:
-* see the CHANGES file
-
-Major changes in release 1.1.1:
-* ares should now compile as C++ code (no longer uses reserved word
- "class").
-* Added SRV support to adig test program.
-* Fixed a few error handling bugs in query processing.
-
-Major changes in release 1.1.0:
-* Added ares_free_string() function so that memory can be freed in the
- same layer as it is allocated, a desirable feature in some
- environments.
-* A few of the ares_dns.h macros are fixed to use the proper bitwise
- operator.
-* Fixed a couple of fenceposts fixed in ares_expand_name()'s
- bounds-checking.
-* In process_timeouts(), extract query->next before calling
- next_server() and possibly freeing the query structure.
-* Casted arguments to ctype macros casted to unsigned char, since not
- all char values are valid inputs to those macros according to ANSI.

-This is c-ares, a forked version of the original ares. The original ares
-README follows below, the c-ares specific details are in README.cares
-
-====================================================================
-
-This is ares, an asynchronous resolver library. It is intended for
-applications which need to perform DNS queries without blocking, or
-need to perform multiple DNS queries in parallel. The primary
-examples of such applications are servers which communicate with
-multiple clients and programs with graphical user interfaces.
-
-This library implementation is not especially portable to crufty old
-systems like SunOS 4. It assumes a compiler which can handle ANSI C
-syntax, a system malloc which properly handles realloc(NULL, foo) and
-free(NULL), and a reasonably up-to-date <arpa/nameser.h>.
-
-I have attempted to preserve the externally visible behavior of the
-BIND resolver in nearly all respects. The API of the library is, of
-course, very different from the synchronous BIND API; instead of
-invoking a function like res_send() and getting a return value back
-indicating the number of bytes in the response, you invoke a function
-like ares_send() and give it a callback function to invoke when the
-response arrives. You then have to select() on the file descriptors
-indicated by ares_fds(), with a timeout given by ares_timeout(). You
-call ares_process() when select() returns.
-
-Some features are missing from the current version of ares, relative
-to the BIND resolver:
-
- * There is no IPV6 support. [not true for c-ares]
- * There is no hostname verification.
- * There is no logging of unexpected events.
- * There is no debugging-oriented logging.
- * There is no YP support.
-
-libares requires an ANSI compiler to compile and use. To build the
-library, just run "./configure" and "make". To install it, run "make
-install". Run "./configure --help" to see a list of options you can
-provide to configure to change how the library builds. libares has no
-data files, so you can move the include file and library around freely
-without leaving behind any dependencies on old paths. Building the
-library will also build the "adig" program, a little toy for trying
-out the library. It doesn't get installed.
-
-libares is distributed at athena-dist.mit.edu:pub/ATHENA/ares. Please
-send bug reports and comments to ghudson@mit.edu.

-c-ares
-======
-
-This package is based on ares 1.1.1 (written by Greg Hudson). I decided to
-fork and release a separate project since the ares author didn't want the
-improvements that were vital for our use of it.
-
-This package is dubbed 'c-ares' since I (Daniel Stenberg) wanted this for use
-within the curl project (hence the letter C) and it makes a nice pun. Also,
-c-ares is not API compatible with ares: a new name makes that more obvious to
-the public.
-
-The full source code is available in the 'c-ares' release archives, and in the
-'ares' subdir of the curl CVS source repository.
-
-If you find bugs, correct flaws, have questions or have comments in general in
-regard to c-ares (or by all means the original ares too), get in touch with us
-on the c-ares mailing list: http://cool.haxx.se/mailman/listinfo/c-ares
-
-c-ares is of course distributed under the same MIT-style license as the
-original ares.
-
-You'll find all c-ares details and news here:
-
- http://c-ares.haxx.se/
-
-
-NOTES FOR C-ARES HACKERS
-
-The following notes apply to c-ares version 1.7.0 and later.
-
-* The distributed ares_build.h file is only intended to be used on systems
- which can not run the also distributed configure script.
-
-* The distributed ares_build.h file is generated as a copy of ares_build.h.dist
- when the c-ares source code distribution archive file is originally created.
-
-* If you check out from CVS on a non-configure platform, you must run the
- appropriate buildconf* script to set up ares_build.h and other local files
- before being able of compiling the library.
-
-* On systems capable of running the configure script, the configure process
- will overwrite the distributed ares_build.h file with one that is suitable
- and specific to the library being configured and built, this new file is
- generated from the ares_build.h.in template file.
-
-* If you intend to distribute an already compiled c-ares library you _MUST_
- also distribute along with it the generated ares_build.h which has been
- used to compile it. Otherwise the library will be of no use for the users of
- the library that you have built. It is _your_ responsability to provide this
- file. No one at the c-ares project can know how you have built the library.
-
-* File ares_build.h includes platform and configuration dependent info,
- and must not be modified by anyone. Configure script generates it for you.
-
-* We cannot assume anything else but very basic compiler features being
- present. While c-ares requires an ANSI C compiler to build, some of the
- earlier ANSI compilers clearly can't deal with some preprocessor operators.
-
-* Newlines must remain unix-style for older compilers' sake.
-
-* Comments must be written in the old-style /* unnested C-fashion */

- How to build c-ares using MSVC or Visual Studio
- =================================================
-
-
-
- How to build using MSVC from the command line
- ---------------------------------------------
-
- Open a command prompt window and ensure that the environment is properly
- set up in order to use MSVC or Visual Studio compiler tools.
-
- Change to c-ares source folder where Makefile.msvc file is located and run:
-
- > nmake -f Makefile.msvc
-
- This will build all c-ares libraries as well as three sample programs.
-
- Once the above command has finished a new folder named MSVCXX will exist
- below the folder where makefile.msvc is found. The name of the folder
- depends on the MSVC compiler version being used to build c-ares.
-
- Below the MSVCXX folder there will exist four folders named 'cares',
- 'ahost', 'acountry', and 'adig'. The 'cares' folder is the one that
- holds the c-ares libraries you have just generated, the other three
- hold sample programs that use the libraries.
-
- The above command builds four versions of the c-ares library, dynamic
- and static versions and each one in release and debug flavours. Each
- of these is found in folders named dll-release, dll-debug, lib-release,
- and lib-debug, which hang from the 'cares' folder mentioned above. Each
- sample program also has folders with the same names to reflect which
- library version it is using.
-
-
- How to build using Visual Studio 6 IDE
- --------------------------------------
-
- A VC++ 6.0 reference workspace (vc6aws.dsw) is available within the 'vc'
- folder to allow proper building of the library and sample programs.
-
- 1) Open the vc6aws.dsw workspace with MSVC6's IDE.
- 2) Select 'Build' from top menu.
- 3) Select 'Batch Build' from dropdown menu.
- 4) Make sure that the sixteen project configurations are 'checked'.
- 5) Click on the 'Build' button.
- 6) Once the sixteen project configurations are built you are done.
-
- Dynamic and static c-ares libraries are built in debug and release flavours,
- and can be located each one in its own subdirectory, dll-debug, dll-release,
- lib-debug and lib-release, all of them below the 'vc\cares' subdirectory.
-
- In the same way four executable versions of each sample program are built,
- each using its respective library. The resulting sample executables are
- located in its own subdirectory, dll-debug, dll-release, lib-debug and
- lib-release, below the 'vc\acountry', 'vc\adig' and 'vc\ahost'folders.
-
- These reference VC++ 6.0 configurations are generated using the dynamic CRT.
-
-
- How to build using Visual Studio 2003 or newer IDE
- --------------------------------------------------
-
- First you have to convert the VC++ 6.0 reference workspace and project files
- to the Visual Studio IDE version you are using, following next steps:
-
- 1) Open vc\vc6aws.dsw with VS20XX.
- 2) Allow VS20XX to update all projects and workspaces.
- 3) Save ALL and close VS20XX.
- 4) Open vc\vc6aws.sln with VS20XX.
- 5) Select batch build, check 'all' projects and click 'build' button.
-
- Same comments relative to generated files and folders as done above for
- Visual Studio 6 IDE apply here.
-
-
- Relationship between c-ares library file names and versions
- -----------------------------------------------------------
-
- c-ares static release library version files:
-
- libcares.lib -> static release library
-
- c-ares static debug library version files:
-
- libcaresd.lib -> static debug library
-
- c-ares dynamic release library version files:
-
- cares.dll -> dynamic release library
- cares.lib -> import library for the dynamic release library
- cares.exp -> export file for the dynamic release library
-
- c-ares dynamic debug library version files:
-
- caresd.dll -> dynamic debug library
- caresd.lib -> import library for the dynamic debug library
- caresd.exp -> export file for the dynamic debug library
- caresd.pdb -> debug symbol file for the dynamic debug library
-
-
- How to use c-ares static libraries
- ----------------------------------
-
- When using the c-ares static library in your program, you will have to
- define preprocessor symbol CARES_STATICLIB while building your program,
- otherwise you will get errors at linkage stage.
-

- * IP-address/hostname to country converter.
- *
- * Problem; you want to know where IP a.b.c.d is located.
- *
- * Use ares_gethostbyname ("d.c.b.a.zz.countries.nerd.dk")
- * and get the CNAME (host->h_name). Result will be:
- * CNAME = zz<CC>.countries.nerd.dk with address 127.0.x.y (ver 1) or
- * CNAME = <a.b.c.d>.zz.countries.nerd.dk with address 127.0.x.y (ver 2)
- *
- * The 2 letter country code is in <CC> and the ISO-3166 country
- * number is in x.y (number = x*256 + y). Version 2 of the protocol is missing
- * the <CC> number.

-
-/*
- * NOTE 1:
- * -------
- *
- * Nothing in this file is intended to be modified or adjusted by the
- * c-ares library user nor by the c-ares library builder.
- *
- * If you think that something actually needs to be changed, adjusted
- * or fixed in this file, then, report it on the c-ares development
- * mailing list: http://cool.haxx.se/mailman/listinfo/c-ares/
- *
- * Try to keep one section per platform, compiler and architecture,
- * otherwise, if an existing section is reused for a different one and
- * later on the original is adjusted, probably the piggybacking one can
- * be adversely changed.
- *
- * In order to differentiate between platforms/compilers/architectures
- * use only compiler built in predefined preprocessor symbols.
- *
- * This header file shall only export symbols which are 'cares' or 'CARES'
- * prefixed, otherwise public name space would be polluted.
- *
- * NOTE 2:
- * -------
- *
- * Right now you might be staring at file ares_build.h.dist or ares_build.h,
- * this is due to the following reason: file ares_build.h.dist is renamed
- * to ares_build.h when the c-ares source code distribution archive file is
- * created.
- *
- * File ares_build.h.dist is not included in the distribution archive.
- * File ares_build.h is not present in the CVS tree.
- *
- * The distributed ares_build.h file is only intended to be used on systems
- * which can not run the also distributed configure script.
- *
- * On systems capable of running the configure script, the configure process
- * will overwrite the distributed ares_build.h file with one that is suitable
- * and specific to the library being configured and built, which is generated
- * from the ares_build.h.in template file.
- *
- * If you check out from CVS on a non-configure platform, you must run the
- * appropriate buildconf* script to set up ares_build.h and other local files.

-.TH ARES_CANCEL 3 "31 March 2004"
-.SH NAME
-ares_cancel \- Cancel a resolve
-.SH SYNOPSIS
-.nf
-.B #include <ares.h>
-.PP
-.B void ares_cancel(ares_channel \fIchannel\fP)
-.fi
-.SH DESCRIPTION
-The \fBares_cancel\fP function cancels all lookups/requests made on the the
-name service channel identified by \fIchannel\fP. \fBares_cancel\fP invokes
-the callbacks for each pending query on the channel, passing a status of
-.BR ARES_ECANCELLED .
-These calls give the callbacks a chance to clean up any state which
-might have been stored in their arguments.
-.SH SEE ALSO
-.BR ares_init (3)
-.BR ares_destroy (3)
-.SH NOTES
-This function was added in c-ares 1.2.0
-
-c-ares 1.6.0 and earlier pass a status of
-.BR ARES_ETIMEOUT
-instead of
-.BR ARES_ECANCELLED .

-.TH ARES_DUP 3 "26 May 2009"
-.SH NAME
-ares_dup \- Duplicate a resolver channel
-.SH SYNOPSIS
-.nf
-.B #include <ares.h>
-.PP
-.B int ares_dup(ares_channel *\fIdest\fP, ares_channel \fIsource\fP)
-.fi
-.SH DESCRIPTION
-The \fBares_dup(3)\fP function duplicates an existing communications channel
-for name service lookups. If it returns successfully, \fBares_dup(3)\fP will
-set the variable pointed to by \fIdest\fP to a handle used to identify the
-name service channel. The caller should invoke \fIares_destroy(3)\fP on the
-handle when the channel is no longer needed.
-
-The \fBares_dup_options\fP function also initializes a name service channel,
-with additional options set exactly as the \fIsource\fP channel has them
-configured.
-.SH SEE ALSO
-.BR ares_destroy(3),
-.BR ares_init(3),
-.BR ares_library_init(3)
-.SH AVAILABILITY
-ares_dup(3) was added in c-ares 1.6.0

-.SH SYNOPSIS

-.PP
-.B int ares_expand_name(const unsigned char *\fIencoded\fP,
-.B const unsigned char *\fIabuf\fP, int \fIalen\fP, char **\fIs\fP,
-.B long *\fIenclen\fP)
-.fi
-.SH DESCRIPTION
-The
-.B ares_expand_name
-function converts a DNS-encoded domain name to a dot-separated C
-string. The argument
-.I encoded
-gives the beginning of the encoded domain name, and the arguments
-.I abuf
-and
-.I alen
-give the containing message buffer (necessary for the processing of
-indirection pointers within the encoded domain name). The result is
-placed in a NUL-terminated allocated buffer, a pointer to which is
-stored in the variable pointed to by
-.IR s .
-The length of the encoded name is stored in the variable pointed to by
-.I enclen
-so that the caller can advance past the encoded domain name to read
-further data in the message.
-.SH RETURN VALUES
-.B ares_expand_name
-can return any of the following values:
-.TP 15
-.B ARES_SUCCESS
-Expansion of the encoded name succeeded.
-.TP 15
-.B ARES_EBADNAME
-The encoded domain name was malformed and could not be expanded.
-.TP 15
-.B ARES_ENOMEM
-Memory was exhausted.

-.TH ARES_GET_SERVERS 3 "5 March 2010"
-.SH NAME
-ares_get_servers \- Retrieve name servers from an initialized ares_channel
-.SH SYNOPSIS
-.nf
-.B #include <ares.h>
-.PP
-.B int ares_get_servers(ares_channel \fIchannel\fP, struct ares_addr_node **\fIservers\fP)
-.fi
-.SH DESCRIPTION
-The \fBares_get_servers(3)\fP function retrieves name servers configuration
-from the
-channel data identified by
-.IR channel ,
-as a linked list of ares_addr_node structs storing a pointer to the first
-node at the address specified by
-.IR servers .
-
-Function caller may traverse the returned name server linked list, or may use
-it directly as suitable input for the \fBares_set_servers(3)\fP function, but
-shall not shrink or extend the list on its own.
-
-Each node of the name server linked list is stored in memory dynamically
-allocated and managed by c-ares. It is the caller's responsibility to free
-the resulting linked list, using \fBares_free_data(3)\fP , once the caller
-does not need it any longer.
-
-This function is capable of handling IPv4 and IPv6 name server
-addresses simultaneously, rendering \fBares_save_options(3)\fP with
-optmask \fBARES_OPT_SERVERS\fP functionally obsolete except for
-IPv4-only name server usage.
-
-.SH RETURN VALUES
-.B ares_get_servers(3)
-may return any of the following values:
-.TP 15
-.B ARES_SUCCESS
-The name servers configuration was successfuly retrieved
-.TP 15
-.B ARES_ENOMEM
-The memory was exhausted
-.TP 15
-.B ARES_ENODATA
-The channel data identified by
-.IR channel
-was invalid.
-.SH SEE ALSO
-.BR ares_set_servers (3),
-.BR ares_init_options (3),
-.BR ares_save_options(3)
-.SH AVAILABILITY
-ares_get_servers(3) was added in c-ares 1.7.1
-.SH AUTHOR
-Implementation of this function and associated library internals are based
-on code, comments and feedback provided November and December of 2008 by
-Daniel Stenberg, Gregor Jasny, Phil Blundell and Yang Tse, December 2009
-by Cedric Bail, February 2010 by Jakub Hrozek. On March 2010 Yang Tse
-shuffled all the bits and this function popped out.

-.TH ARES_GETHOSTBYADDR 3 "24 July 1998"
-.SH NAME
-ares_gethostbyaddr \- Initiate a host query by address
-.SH SYNOPSIS
-.nf
-.B #include <ares.h>
-.PP
-.B typedef void (*ares_host_callback)(void *\fIarg\fP, int \fIstatus\fP,
-.B int \fItimeouts\fP, struct hostent *\fIhostent\fP)
-.PP
-.B void ares_gethostbyaddr(ares_channel \fIchannel\fP, const void *\fIaddr\fP,
-.B int \fIaddrlen\fP, int \fIfamily\fP, ares_host_callback \fIcallback\fP,
-.B void *\fIarg\fP)
-.fi
-.SH DESCRIPTION
-The
-.B ares_gethostbyaddr
-function initiates a host query by address on the name service channel
-identified by
-.IR channel .
-The parameters
-.I addr
-and
-.I addrlen
-give the address as a series of bytes, and
-.I family
-gives the type of address. When the query is complete or has failed, the ares
-library will invoke \fIcallback\fP. Completion or failure of the query may
-happen immediately, or may happen during a later call to
-\fIares_process(3)\fP, \fIares_destroy(3)\fP or \fIares_cancel(3)\fP.
-.PP
-The callback argument
-.I arg
-is copied from the
-.B ares_gethostbyaddr
-argument
-.IR arg .
-The callback argument
-.I status
-indicates whether the query succeeded and, if not, how it failed. It
-may have any of the following values:
-.TP 19
-.B ARES_SUCCESS
-The host lookup completed successfully.
-.TP 19
-.B ARES_ENOTIMP
-The ares library does not know how to look up addresses of type
-.IR family .
-.TP 19
-.B ARES_ENOTFOUND
-The address
-.I addr
-was not found.
-.TP 19
-.B ARES_ENOMEM
-Memory was exhausted.
-.TP 19
-.B ARES_EDESTRUCTION
-The name service channel
-.I channel
-is being destroyed; the query will not be completed.
-.PP
-The callback argument
-.I timeouts
-reports how many times a query timed out during the execution of the
-given request.
-.PP
-On successful completion of the query, the callback argument
-.I hostent
-points to a
-.B struct hostent
-containing the name of the host returned by the query. The callback
-need not and should not attempt to free the memory pointed to by
-.IR hostent ;
-the ares library will free it when the callback returns. If the query
-did not complete successfully,
-.I hostent
-will be
-.BR NULL .

-.TH ARES_GETHOSTBYNAME 3 "25 July 1998"
-.SH NAME
-ares_gethostbyname \- Initiate a host query by name
-.SH SYNOPSIS
-.nf
-.B #include <ares.h>
-.PP
-.B typedef void (*ares_host_callback)(void *\fIarg\fP, int \fIstatus\fP,
-.B int \fItimeouts\fP, struct hostent *\fIhostent\fP)
-.PP
-.B void ares_gethostbyname(ares_channel \fIchannel\fP, const char *\fIname\fP,
-.B int \fIfamily\fP, ares_host_callback \fIcallback\fP, void *\fIarg\fP)
-.fi
-.SH DESCRIPTION
-The
-.B ares_gethostbyname
-function initiates a host query by name on the name service channel
-identified by
-.IR channel .
-The parameter
-.I name
-gives the hostname as a NUL-terminated C string, and
-.I family
-gives the desired type of address for the resulting host entry. When the
-query is complete or has failed, the ares library will invoke \fIcallback\fP.
-Completion or failure of the query may happen immediately, or may happen
-during a later call to \fIares_process(3)\fP, \fIares_destroy(3)\fP or
-\fIares_cancel(3)\fP.
-.PP
-The callback argument
-.I arg
-is copied from the
-.B ares_gethostbyname
-argument
-.IR arg .
-The callback argument
-.I status
-indicates whether the query succeeded and, if not, how it failed. It
-may have any of the following values:
-.TP 19
-.B ARES_SUCCESS
-The host lookup completed successfully.
-.TP 19
-.B ARES_ENOTIMP
-The ares library does not know how to find addresses of type
-.IR family .
-.TP 19
-.B ARES_EBADNAME
-The hostname
-.B name
-is composed entirely of numbers and periods, but is not a valid
-representation of an Internet address.
-.TP 19
-.B ARES_ENOTFOUND
-The address
-.I addr
-was not found.
-.TP 19
-.B ARES_ENOMEM
-Memory was exhausted.
-.TP 19
-.B ARES_EDESTRUCTION
-The name service channel
-.I channel
-is being destroyed; the query will not be completed.
-.PP
-The callback argument
-.I timeouts
-reports how many times a query timed out during the execution of the
-given request.
-.PP
-On successful completion of the query, the callback argument
-.I hostent
-points to a
-.B struct hostent
-containing the name of the host returned by the query. The callback
-need not and should not attempt to free the memory pointed to by
-.IR hostent ;
-the ares library will free it when the callback returns. If the query
-did not complete successfully,
-.I hostent
-will be
-.BR NULL .

-.SH NAME
-ares_gethostbyname_file \- Lookup a name in the system's hosts file
-.SH SYNOPSIS
-.nf
-.B #include <ares.h>
-.PP
-.B int ares_gethostbyname_file(ares_channel \fIchannel\fP, const char *\fIname\fP,
-.B int \fIfamily\fP, struct hostent **host)
-.fi
-.SH DESCRIPTION
-The
-.B ares_gethostbyname_file
-function performs a host lookup by name against the system's hosts file (or equivalent local hostname database).
-The
-.IR channel
-parameter is required, but no asynchronous queries are performed. Instead, the
-lookup is done via the same mechanism used to perform 'f' lookups
-(see the
-.I lookups
-options field in \fIares_init_options(3)\fP).
-The parameter
-.I name
-gives the hostname as a NUL-terminated C string, and
-.I family
-gives the desired type of address for the resulting host entry.
-.PP
-The return value indicates whether the query succeeded and, if not, how it
-failed. It may have any of the following values:
-.TP 19
-.B ARES_SUCCESS
-The host lookup completed successfully and
-.I host
-now points to the result (and must be freed with \fIares_free_hostent(3)\fP).
-.TP 19
-.B ARES_ENOTFOUND
-The hostname
-.I name
-was not found.
-.TP 19
-.B ARES_EFILE
-There was a file I/O error while performing the lookup.
-.TP 19
-.B ARES_ENOMEM
-Memory was exhausted.
-.PP
-On successful completion of the query, the pointer pointed to by
-.I host
-points to a
-.B struct hostent
-containing the address of the host returned by the lookup. The user must
-free the memory pointed to by
-.IR host
-when finished with it by calling \fIares_free_hostent(3)\fP. If the lookup did
-not complete successfully,
-.I host
-will be
-.BR NULL .

-.TH ARES_GETNAMEINFO 3 "1 May 2009"
-.SH NAME
-ares_getnameinfo \- Address-to-nodename translation in protocol-independent manner
-.SH SYNOPSIS
-.nf
-.B #include <ares.h>
-.PP
-.B typedef void (*ares_nameinfo_callback)(void *\fIarg\fP, int \fIstatus\fP,
-.B int \fItimeouts\fP, char *\fInode\fP, char *\fIservice\fP)
-.PP
-.B void ares_getnameinfo(ares_channel \fIchannel\fP, const struct sockaddr *\fIsa\fP,
-.B ares_socklen_t \fIsalen\fP, int \fIflags\fP, ares_nameinfo_callback \fIcallback\fP,
-.B void *\fIarg\fP)
-.fi
-.SH DESCRIPTION
-The
-.B ares_getnameinfo
-function is defined for protocol-independent address translation. The function
-is a combination of \fIares_gethostbyaddr(3)\fP and \fIgetservbyport(3)\fP. The function will
-translate the address either by executing a host query on the name service channel
-identified by
-.IR channel
-or it will attempt to resolve it locally if possible.
-The parameters
-.I sa
-and
-.I len
-give the address as a sockaddr structure, and
-.I flags
-gives the options that the function will use. Valid flags are listed below:
-.TP 19
-.B ARES_NI_NOFQDN
-Only the nodename portion of the FQDN is returned for local hosts.
-.TP 19
-.B ARES_NI_NUMERICHOST
-The numeric form of the hostname is returned rather than the name.
-.TP 19
-.B ARES_NI_NAMEREQD
-An error is returned if the hostname cannot be found in the DNS.
-.TP 19
-.B ARES_NI_NUMERICSERV
-The numeric form of the service is returned rather than the name.
-.TP 19
-.B ARES_NI_TCP
-The service name is to be looked up for the TCP protocol.
-.TP 19
-.B ARES_NI_UDP
-The service name is to be looked up for the UDP protocol.
-.TP 19
-.B ARES_NI_SCTP
-The service name is to be looked up for the SCTP protocol.
-.TP 19
-.B ARES_NI_DCCP
-The service name is to be looked up for the DCCP protocol.
-.TP 19
-.B ARES_NI_NUMERICSCOPE
-The numeric form of the scope ID is returned rather than the name.
-.TP 19
-.B ARES_NI_LOOKUPHOST
-A hostname lookup is being requested.
-.TP 19
-.B ARES_NI_LOOKUPSERVICE
-A service name lookup is being requested.
-.PP
-When the query
-is complete or has
-failed, the ares library will invoke \fIcallback\fP. Completion or failure of
-the query may happen immediately, or may happen during a later call to
-\fIares_process(3)\fP, \fIares_destroy(3)\fP or \fIares_cancel(3)\fP.
-.PP
-The callback argument
-.I arg
-is copied from the
-.B ares_getnameinfo
-argument
-.IR arg .
-The callback argument
-.I status
-indicates whether the query succeeded and, if not, how it failed. It
-may have any of the following values:
-.TP 19
-.B ARES_SUCCESS
-The host lookup completed successfully.
-.TP 19
-.B ARES_ENOTIMP
-The ares library does not know how to look up addresses of type
-.IR family .
-.TP 19
-.B ARES_ENOTFOUND
-The address
-.I addr
-was not found.
-.TP 19
-.B ARES_ENOMEM
-Memory was exhausted.
-.TP 19
-.B ARES_EDESTRUCTION
-The name service channel
-.I channel
-is being destroyed; the query will not be completed.
-.TP 19
-.B ARES_EBADFLAGS
-The
-.I flags
-parameter contains an illegal value.
-.PP
-The callback argument
-.I timeouts
-reports how many times a query timed out during the execution of the
-given request.
-.PP
-On successful completion of the query, the callback argument
-.I node
-contains a string representing the hostname (assuming
-.B ARES_NI_LOOKUPHOST
-was specified). Additionally,
-.I service
-contains a string representing the service name (assuming
-.B ARES_NI_LOOKUPSERVICE
-was specified).
-If the query did not complete successfully, or one of the values
-was not requested,
-.I node
-or
-.I service
-will be
-.BR NULL .

-.TH ARES_GETSOCK 3 "11 March 2010"
-.SH NAME
-ares_getsock \- get socket descriptors to wait on
-.SH SYNOPSIS
-.nf
-.B #include <ares.h>
-.PP
-.B int ares_getsock(ares_channel \fIchannel\fP, ares_socket_t *\fIsocks\fP,
-.B int \fInumsocks\fP);
-.fi
-.SH DESCRIPTION
-The
-.B ares_getsock
-function retrieves the set of socket descriptors which the calling
-application should wait on for reading and/or writing for the
-processing of name service queries pending on the name service channel
-identified by
-.IR channel .
-Socket descriptors will be set in the socket descriptor array pointed to by
-\fIsocks\fP.
-\fInumsocks\fP is the size of the given array in number of ints.
-
-This function can only return information about up to 16 sockets. If more are
-in use (however unlikely that is), they are simply not reported back.
-.SH RETURN VALUES
-\fBares_getsock\fP returns a bitmask for what actions to wait for on the
-different sockets. The ares.h header file provides these convenience macros to
-extract the information appropriately:
-
-.nf
-#define ARES_GETSOCK_MAXNUM 16 /* ares_getsock() can return info about
- this many sockets */
-#define ARES_GETSOCK_READABLE(bits,num) (bits & (1<< (num)))
-#define ARES_GETSOCK_WRITABLE(bits,num) (bits & (1 << ((num) + \

-.TH ARES_INIT 3 "5 March 2010"
-.SH NAME
-ares_init, ares_init_options \- Initialize a resolver channel
-.SH SYNOPSIS
-.nf
-.B #include <ares.h>
-.PP
-.B int ares_init(ares_channel *\fIchannelptr\fP)
-.B int ares_init_options(ares_channel *\fIchannelptr\fP,
-.B struct ares_options *\fIoptions\fP, int \fIoptmask\fP)
-.PP
-.B cc file.c -lcares
-.fi
-.SH DESCRIPTION
-The \fBares_init\fP function initializes a communications channel for name
-service lookups. If it returns successfully, \fBares_init\fP will set the
-variable pointed to by \fIchannelptr\fP to a handle used to identify the name
-service channel. The caller should invoke
-.BR ares_destroy (3)
-on the handle when the channel is no longer needed.
-.PP
-The \fBares_init_options\fP function also initializes a name service channel,
-with additional options useful for applications requiring more control over
-name service configuration. The \fIoptmask\fP parameter specifies which fields
-in the structure pointed to by \fIoptions\fP are set, as follows:
-.TP 18
-.B ARES_OPT_FLAGS
-.B int \fIflags\fP;
-.br
-Flags controlling the behavior of the resolver. See below for a
-description of possible flag values.
-.TP 18
-.B ARES_OPT_TIMEOUT
-.B int \fItimeout\fP;
-.br
-The number of seconds each name server is given to respond to a query on the
-first try. (After the first try, the timeout algorithm becomes more
-complicated, but scales linearly with the value of \fItimeout\fP.) The
-default is five seconds. This option is being deprecated by
-\fIARES_OPT_TIMEOUTMS\fP starting in c-ares 1.5.2.
-.TP 18
-.B ARES_OPT_TIMEOUTMS
-.B int \fItimeout\fP;
-.br
-The number of milliseconds each name server is given to respond to a query on
-the first try. (After the first try, the timeout algorithm becomes more
-complicated, but scales linearly with the value of \fItimeout\fP.) The
-default is five seconds. Note that this option is specified with the same
-struct field as the former \fIARES_OPT_TIMEOUT\fP, it is but the option bits
-that tell c-ares how to interpret the number. This option was added in c-ares
-1.5.2.
-.TP 18
-.B ARES_OPT_TRIES
-.B int \fItries\fP;
-.br
-The number of tries the resolver will try contacting each name server
-before giving up. The default is four tries.
-.TP 18
-.B ARES_OPT_NDOTS
-.B int \fIndots\fP;
-.br
-The number of dots which must be present in a domain name for it to be
-queried for "as is" prior to querying for it with the default domain
-extensions appended. The default value is 1 unless set otherwise by
-resolv.conf or the RES_OPTIONS environment variable.
-.TP 18
-.B ARES_OPT_PORT
-.B unsigned short \fIport\fP;
-.br
-The port to use for queries (both TCP and UDP), in network byte order.
-The default value is 53 (in network byte order), the standard name
-service port.
-.TP 18
-.B ARES_OPT_SERVERS
-.B struct in_addr *\fIservers\fP;
-.br
-.B int \fInservers\fP;
-.br
-The list of IPv4 servers to contact, instead of the servers specified in
-resolv.conf or the local named. In order to allow specification of either
-IPv4 or IPv6 name servers, function
-.BR ares_set_servers(3)
-must be used instead.
-.TP 18
-.B ARES_OPT_DOMAINS
-.B char **\fIdomains\fP;
-.br
-.B int \fIndomains\fP;
-.br
-The domains to search, instead of the domains specified in resolv.conf
-or the domain derived from the kernel hostname variable.
-.TP 18
-.B ARES_OPT_LOOKUPS
-.B char *\fIlookups\fP;
-.br
-The lookups to perform for host queries.
-.I lookups
-should be set to a string of the characters "b" or "f", where "b"
-indicates a DNS lookup and "f" indicates a lookup in the hosts file.
-.TP 18
-.B ARES_OPT_SOCK_STATE_CB
-.B void (*\fIsock_state_cb\fP)(void *data, int s, int read, int write);
-.br
-.B void *\fIsock_state_cb_data\fP;
-.br
-A callback function to be invoked when a socket changes state.
-.I s
-will be passed the socket whose state has changed;
-.I read
-will be set to true if the socket should listen for read events, and
-.I write
-will be set to true if the socket should listen for write events.
-The value of
-.I sock_state_cb_data
-will be passed as the
-.I data
-argument.
-.PP
-The
-.I flags
-field should be the bitwise or of some subset of the following values:
-.TP 23
-.B ARES_FLAG_USEVC
-Always use TCP queries (the "virtual circuit") instead of UDP
-queries. Normally, TCP is only used if a UDP query yields a truncated
-result.
-.TP 23
-.B ARES_FLAG_PRIMARY
-Only query the first server in the list of servers to query.
-.TP 23
-.B ARES_FLAG_IGNTC
-If a truncated response to a UDP query is received, do not fall back
-to TCP; simply continue on with the truncated response.
-.TP 23
-.B ARES_FLAG_NORECURSE
-Do not set the "recursion desired" bit on outgoing queries, so that the name
-server being contacted will not try to fetch the answer from other servers if
-it doesn't know the answer locally. Be aware that ares will not do the
-recursion for you. Recursion must be handled by the application calling ares
-if \fIARES_FLAG_NORECURSE\fP is set.
-.TP 23
-.B ARES_FLAG_STAYOPEN
-Do not close communications sockets when the number of active queries
-drops to zero.
-.TP 23
-.B ARES_FLAG_NOSEARCH
-Do not use the default search domains; only query hostnames as-is or
-as aliases.
-.TP 23
-.B ARES_FLAG_NOALIASES
-Do not honor the HOSTALIASES environment variable, which normally
-specifies a file of hostname translations.
-.TP 23
-.B ARES_FLAG_NOCHECKRESP
-Do not discard responses with the SERVFAIL, NOTIMP, or REFUSED
-response code or responses whose questions don't match the questions
-in the request. Primarily useful for writing clients which might be
-used to test or debug name servers.
-.SH RETURN VALUES
-.I ares_init
-or
-.I ares_init_options
-can return any of the following values:
-.TP 14
-.B ARES_SUCCESS
-Initialization succeeded.
-.TP 14
-.B ARES_EFILE
-A configuration file could not be read.
-.TP 14
-.B ARES_ENOMEM
-The process's available memory was exhausted.
-.TP 14
-.B ARES_ENOTINITIALIZED
-c-ares library initialization not yet performed.

-.TH ARES_LIBRARY_CLEANUP 3 "19 May 2009"
-.SH NAME
-ares_library_cleanup \- c-ares library deinitialization
-.SH SYNOPSIS
-.nf
-.B #include <ares.h>
-.PP
-.B void ares_library_cleanup(void)
-.PP
-.B cc file.c -lcares
-.fi
-.SH DESCRIPTION
-.PP
-The
-.B ares_library_cleanup
-function uninitializes the c-ares library, freeing all resources
-previously aquired by \fIares_library_init(3)\fP when the library
-was initialized.
-.PP
-This function must be called when the program using c-ares will
-no longer need any c-ares function. Once the program has called
-\fIares_library_cleanup(3)\fP it shall not make any further call to any
-c-ares function.
-.PP
-This function does not cancel any pending c-ares lookups or requests
-previously done. Program must use \fIares_cancel(3)\fP for this purpose.
-.PP
-.B This function is not thread safe.
-You have to call it once the program is about to terminate, but this call must
-be done once the program has terminated every single thread that it could have
-initiated. This is required to avoid potential race conditions in library
-deinitialization, and also due to the fact that \fIares_library_cleanup(3)\fP
-might call functions from other libraries that are thread unsafe, and could
-conflict with any other thread that is already using these other libraries.
-.PP
-Win32/64 application DLLs shall not call \fIares_library_cleanup(3)\fP from
-the DllMain function. Doing so will produce deadlocks and other problems.
-.SH AVAILABILITY
-This function was first introduced in c-ares version 1.7.0 along with the
-definition of preprocessor symbol \fICARES_HAVE_ARES_LIBRARY_CLEANUP\fP as an
-indication of the availability of this function.
-.PP
-Since the introduction of this function, it is absolutely mandatory to call it
-for any Win32/64 program using c-ares.
-.PP
-Non-Win32/64 systems can still use c-ares version 1.7.0 without calling
-\fIares_library_cleanup(3)\fP due to the fact that \fIcurrently\fP it is nearly
-a do-nothing function on non-Win32/64 platforms.

-.TH ARES_LIBRARY_INIT 3 "19 May 2009"
-.SH NAME
-ares_library_init \- c-ares library initialization
-.SH SYNOPSIS
-.nf
-.B #include <ares.h>
-.PP
-.B int ares_library_init(int \fIflags\fP)
-.PP
-.B cc file.c -lcares
-.fi
-.SH DESCRIPTION
-.PP
-The
-.B ares_library_init
-function performs initializations internally required by the c-ares
-library that must take place before any other function provided by
-c-ares can be used in a program.
-.PP
-This function must be called one time within the life of a program,
-before the program actually executes any other c-ares library function.
-Initializations done by this function remain effective until a
-call to \fIares_library_cleanup(3)\fP is performed.
-.PP
-Successive calls to this function do nothing, only the first call done
-when c-ares is in an uninitialized state is actually effective.
-.PP
-The
-.I flags
-parameter is a bit pattern that tells c-ares exactly which features
-should be initialized, as described below. Set the desired bits by
-ORing the values together. In normal operation you should specify
-\fIARES_LIB_INIT_ALL\fP. Don't use any other value unless you are
-familiar with it and trying to control some internal c-ares feature.
-.PP
-.B This function is not thread safe.
-You have to call it once the program has started, but this call must be done
-before the program starts any other thread. This is required to avoid
-potential race conditions in library initialization, and also due to the fact
-that \fIares_library_init(3)\fP might call functions from other libraries that
-are thread unsafe, and could conflict with any other thread that is already
-using these other libraries.
-.PP
-Win32/64 application DLLs shall not call \fIares_library_init(3)\fP from the
-DllMain function. Doing so will produce deadlocks and other problems.
-.SH FLAGS
-.TP 5
-.B ARES_LIB_INIT_ALL
-Initialize everything possible. This sets all known bits.
-.TP
-.B ARES_LIB_INIT_WIN32
-Initialize Win32/64 specific libraries.
-.TP
-.B ARES_LIB_INIT_NONE
-Initialize nothing extra. This sets no bit.
-.SH RETURN VALUE
-Upon successful completion, ares_library_init() will return 0. Otherwise, a
-non-zero error number will be returned to indicate the error. Except for
-\fIares_strerror(3)\fP, you shall not call any other c-ares function upon
-\fIares_library_init(3)\fP failure.
-.SH AVAILABILITY
-This function was first introduced in c-ares version 1.7.0 along with the
-definition of preprocessor symbol \fICARES_HAVE_ARES_LIBRARY_INIT\fP as an
-indication of the availability of this function.
-.PP
-Since the introduction of this function it is absolutely mandatory to
-call it for any Win32/64 program using c-ares.
-.PP
-Non-Win32/64 systems can still use c-ares version 1.7.0 without calling
-\fIares_library_init(3)\fP due to the fact that \fIcurrently\fP it is nearly
-a do-nothing function on non-Win32/64 platforms at this point.

-.TH ARES_MKQUERY 3 "20 Nov 2009"
-.SH NAME
-ares_mkquery \- Compose a single-question DNS query buffer
-.SH SYNOPSIS
-.nf
-.B #include <ares.h>
-.PP
-.B int ares_mkquery(const char *\fIname\fP, int \fIdnsclass\fP, int \fItype\fP,
-.B unsigned short \fIid\fP, int \fIrd\fP, unsigned char **\fIbuf\fP,
-.B int *\fIbuflen\fP)
-.fi
-.SH DESCRIPTION
-The
-.B ares_mkquery
-function composes a DNS query with a single question.
-The parameter
-.I name
-gives the query name as a NUL-terminated C string of period-separated
-labels optionally ending with a period; periods and backslashes within
-a label must be escaped with a backlash. The parameters
-.I dnsclass
-and
-.I type
-give the class and type of the query using the values defined in
-.BR <arpa/nameser.h> .
-The parameter
-.I id
-gives a 16-bit identifier for the query. The parameter
-.I rd
-should be nonzero if recursion is desired, zero if not. The query
-will be placed in an allocated buffer, a pointer to which will be
-stored in the variable pointed to by
-.IR buf ,
-and the length of which will be stored in the variable pointed to by
-.IR buflen .
-It is the caller's responsibility to free this buffer using
-\fIares_free_string(3)\fP when it is no longer needed.
-.SH RETURN VALUES
-.B ares_mkquery
-can return any of the following values:
-.TP 15
-.B ARES_SUCCESS
-Construction of the DNS query succeeded.
-.TP 15
-.B ARES_EBADNAME
-The query name
-.I name
-could not be encoded as a domain name, either because it contained a
-zero-length label or because it contained a label of more than 63
-characters.
-.TP 15
-.B ARES_ENOMEM
-Memory was exhausted.
-.SH SEE ALSO
-.BR ares_expand_name (3),
-.BR ares_free_string (3)

-.SH NAME
-ares_parse_a_reply \- Parse a reply to a DNS query of type A
-.SH SYNOPSIS
-.nf
-.B #include <ares.h>
-.PP
-.B int ares_parse_a_reply(const unsigned char *\fIabuf\fP, int \fIalen\fP,
-.B struct hostent **\fIhost\fP,
-.B struct ares_addrttl *\fIaddrttls\fB, int *\fInaddrttls\fB);
-.fi
-.SH DESCRIPTION
-The
-.B ares_parse_a_reply
-function parses the response to a query of type A into a
-.BR "struct hostent"
-and/or an array of
-.BR "struct ares_addrttls" .
-The parameters
-.I abuf
-and
-.I alen
-give the contents of the response. The result is stored in allocated
-memory and a pointer to it stored into the variable pointed to by
-.IR host ,
-if host is nonnull.
-It is the caller's responsibility to free the resulting host structure
-using
-.BR ares_free_hostent (3)
-when it is no longer needed.
-.PP
-If
-.IR addrttls
-and
-.IR naddrttls
-are both nonnull,
-then up to *naddrttls
-.BR "struct ares_addrttl"
-records are stored in the array pointed to by addrttls,
-and then *naddrttls is set to the number of records so stored.
-Note that the memory for these records is supplied by the caller.
-.SH RETURN VALUES
-.B ares_parse_a_reply
-can return any of the following values:
-.TP 15
-.B ARES_SUCCESS
-The response was successfully parsed.
-.TP 15

-.TH ARES_PARSE_AAAA_REPLY 3 "20 Nov 2009"
-.SH NAME
-ares_parse_aaaa_reply \- Parse a reply to a DNS query of type AAAA
-.SH SYNOPSIS
-.nf
-.B #include <ares.h>
-.PP
-.B int ares_parse_aaaa_reply(const unsigned char *\fIabuf\fP, int \fIalen\fP,
-.B struct hostent **\fIhost\fP,
-.B struct ares_addr6ttl *\fIaddrttls\fB, int *\fInaddrttls\fB);
-.fi
-.SH DESCRIPTION
-The
-.B ares_parse_aaaa_reply
-function parses the response to a query of type AAAA into a
-.BR "struct hostent"
-and/or an array of
-.BR "struct ares_addr6ttl" .
-The parameters
-.I abuf
-and
-.I alen
-give the contents of the response. The result is stored in allocated
-memory and a pointer to it stored into the variable pointed to by
-.IR host ,
-if host is nonnull.
-It is the caller's responsibility to free the resulting host structure
-using
-.BR ares_free_hostent (3)
-when it is no longer needed.
-.PP
-If
-.IR addrttls
-and
-.IR naddrttls
-are both nonnull,
-then up to *naddrttls
-.BR "struct ares_addr6ttl"
-records are stored in the array pointed to by addrttls,
-and then *naddrttls is set to the number of records so stored.
-Note that the memory for these records is supplied by the caller.
-.SH RETURN VALUES
-.B ares_parse_aaaa_reply
-can return any of the following values:
-.TP 15
-.B ARES_SUCCESS
-The response was successfully parsed.
-.TP 15
-.B ARES_EBADRESP
-The response was malformatted.
-.TP 15
-.B ARES_ENODATA
-The response did not contain an answer to the query.
-.TP 15
-.B ARES_ENOMEM
-Memory was exhausted.

-.TH ARES_PARSE_PTR_REPLY 3 "25 July 1998"
-.SH NAME
-ares_parse_ptr_reply \- Parse a reply to a DNS query of type PTR into a hostent
-.SH SYNOPSIS
-.nf
-.B #include <ares.h>
-.PP
-.B int ares_parse_ptr_reply(const unsigned char *\fIabuf\fP, int \fIalen\fP,
-.B const void *\fIaddr\fP, int \fIaddrlen\fP, int \fIfamily\fP,
-.B struct hostent **\fIhost\fP);
-.fi
-.SH DESCRIPTION
-The
-.B ares_parse_ptr_reply
-function parses the response to a query of type PTR into a
-.BR "struct hostent" .
-The parameters
-.I abuf
-and
-.I alen
-give the contents of the response. The parameters
-.IR addr ,
-.IR addrlen ,
-and
-.I family
-specify which address was queried for; they are not used to verify the
-response, merely used to fill in the address of the
-.BR "struct hostent" .
-The resulting
-.B struct hostent
-is stored in allocated memory and a pointer to it stored into the
-variable pointed to by
-.IR host .
-It is the caller's responsibility to free the resulting host structure
-using
-.BR ares_free_hostent (3)
-when it is no longer needed.
-.SH RETURN VALUES
-.B ares_parse_ptr_reply
-can return any of the following values:
-.TP 15
-.B ARES_SUCCESS
-The response was successfully parsed.
-.TP 15
-.B ARES_EBADRESP
-The response was malformatted.
-.TP 15
-.B ARES_ENODATA
-The response did not contain an answer to the query.
-.TP 15
-.B ARES_ENOMEM
-Memory was exhausted.
-.SH SEE ALSO

-.TH ARES_PROCESS 3 "25 July 1998"
-.SH NAME
-ares_process \- Process events for name resolution
-.SH SYNOPSIS
-.nf
-.B #include <ares.h>
-.PP
-.B void ares_process(ares_channel \fIchannel\fP, fd_set *\fIread_fds\fP,
-.B fd_set *\fIwrite_fds\fP)
-.fi
-.PP
-.B void ares_process_fd(ares_channel \fIchannel\fP,
-.B ares_socket_t \fIread_fd\fP,
-.B ares_socket_t \fIwrite_fd\fP)
-.fi
-.SH DESCRIPTION
-The \fBares_process(3)\fP function handles input/output events and timeouts
-associated with queries pending on the name service channel identified by
-.IR channel .
-The file descriptor sets pointed to by \fIread_fds\fP and \fIwrite_fds\fP
-should have file descriptors set in them according to whether the file
-descriptors specified by \fIares_fds(3)\fP are ready for reading and writing.
-(The easiest way to determine this information is to invoke
-.B select
-with a timeout no greater than the timeout given by \fIares_timeout(3)\fP ).
-.PP
-The
-.B ares_process
-function will invoke callbacks for pending queries if they complete
-successfully or fail.
-
-\fBares_process_fd(3)\fP works the same way but acts and operates only on the
-specific file descriptors (sockets) you pass in to the function. Use
-ARES_SOCKET_BAD for "no action". This function is of course provided to allow
-users of c-ares to void select() in their applications and within c-ares.
-.SS EXAMPLE
-The following code fragment waits for all pending queries on a channel
-to complete:
-.PP
-.RS
-.nf
-int nfds, count;
-fd_set readers, writers;
-struct timeval tv, *tvp;
-
-while (1)
- {
- FD_ZERO(&readers);
- FD_ZERO(&writers);
- nfds = ares_fds(channel, &readers, &writers);
- if (nfds == 0)
- break;
- tvp = ares_timeout(channel, NULL, &tv);
- count = select(nfds, &readers, &writers, NULL, tvp);
- ares_process(channel, &readers, &writers);
- }

-.TH ARES_QUERY 3 "24 July 1998"
-.SH NAME
-ares_query \- Initiate a single-question DNS query
-.SH SYNOPSIS
-.nf
-.B #include <ares.h>
-.PP
-.B typedef void (*ares_callback)(void *\fIarg\fP, int \fIstatus\fP,
-.B int \fItimeouts\fP, unsigned char *\fIabuf\fP, int \fIalen\fP)
-.PP
-.B void ares_query(ares_channel \fIchannel\fP, const char *\fIname\fP,
-.B int \fIdnsclass\fP, int \fItype\fP, ares_callback \fIcallback\fP,
-.B void *\fIarg\fP)
-.fi
-.SH DESCRIPTION
-The
-.B ares_query
-function initiates a single-question DNS query on the name service
-channel identified by
-.IR channel .
-The parameter
-.I name
-gives the query name as a NUL-terminated C string of period-separated
-labels optionally ending with a period; periods and backslashes within
-a label must be escaped with a backslash. The parameters
-.I dnsclass
-and
-.I type
-give the class and type of the query using the values defined in
-.BR <arpa/nameser.h> .
-When the query is complete or has failed, the ares library will invoke
-.IR callback .
-Completion or failure of the query may happen immediately, or may
-happen during a later call to
-.BR ares_process (3)
-or
-.BR ares_destroy (3).
-.PP
-The callback argument
-.I arg
-is copied from the
-.B ares_query
-argument
-.IR arg .
-The callback argument
-.I status
-indicates whether the query succeeded and, if not, how it failed. It
-may have any of the following values:
-.TP 19
-.B ARES_SUCCESS
-The query completed successfully.
-.TP 19
-.B ARES_ENODATA
-The query completed but contains no answers.
-.TP 19
-.B ARES_EFORMERR
-The query completed but the server claims that the query was
-malformatted.
-.TP 19
-.B ARES_ESERVFAIL
-The query completed but the server claims to have experienced a
-failure. (This code can only occur if the
-.B ARES_FLAG_NOCHECKRESP
-flag was specified at channel initialization time; otherwise, such
-responses are ignored at the
-.BR ares_send (3)
-level.)
-.TP 19
-.B ARES_ENOTFOUND
-The query completed but the queried-for domain name was not found.
-.TP 19
-.B ARES_ENOTIMP
-The query completed but the server does not implement the operation
-requested by the query. (This code can only occur if the
-.B ARES_FLAG_NOCHECKRESP
-flag was specified at channel initialization time; otherwise, such
-responses are ignored at the
-.BR ares_send (3)
-level.)
-.TP 19
-.B ARES_EREFUSED
-The query completed but the server refused the query. (This code can
-only occur if the
-.B ARES_FLAG_NOCHECKRESP
-flag was specified at channel initialization time; otherwise, such
-responses are ignored at the
-.BR ares_send (3)
-level.)
-.TP 19
-.B ARES_EBADNAME
-The query name
-.I name
-could not be encoded as a domain name, either because it contained a
-zero-length label or because it contained a label of more than 63
-characters.
-.TP 19
-.B ARES_ETIMEOUT
-No name servers responded within the timeout period.
-.TP 19
-.B ARES_ECONNREFUSED
-No name servers could be contacted.
-.TP 19
-.B ARES_ENOMEM
-Memory was exhausted.
-.TP 19
-.B ARES_EDESTRUCTION
-The name service channel
-.I channel
-is being destroyed; the query will not be completed.
-.PP
-The callback argument
-.I timeouts
-reports how many times a query timed out during the execution of the
-given request.
-.PP
-If the query completed (even if there was something wrong with it, as
-indicated by some of the above error codes), the callback argument
-.I abuf
-points to a result buffer of length
-.IR alen .
-If the query did not complete,
-.I abuf
-will be NULL and
-.I alen
-will be 0.

-/* ================================================================ */
-
-/*
- * NOTE 1:
- * -------
- *
- * All checks done in this file are intentionally placed in a public
- * header file which is pulled by ares.h when an application is
- * being built using an already built c-ares library. Additionally
- * this file is also included and used when building the library.
- *
- * If compilation fails on this file it is certainly sure that the
- * problem is elsewhere. It could be a problem in the ares_build.h
- * header file, or simply that you are using different compilation
- * settings than those used to build the library.
- *
- * Nothing in this file is intended to be modified or adjusted by the
- * c-ares library user nor by the c-ares library builder.
- *
- * Do not deactivate any check, these are done to make sure that the
- * library is properly built and used.
- *
- * You can find further help on the c-ares development mailing list:
- * http://cool.haxx.se/mailman/listinfo/c-ares/
- *
- * NOTE 2
- * ------
- *
- * Some of the following compile time checks are based on the fact
- * that the dimension of a constant array can not be a negative one.
- * In this way if the compile time verification fails, the compilation
- * will fail issuing an error. The error description wording is compiler
- * dependent but it will be quite similar to one of the following:
- *
- * "negative subscript or subscript is too large"
- * "array must have at least one element"
- * "-1 is an illegal array size"
- * "size of array is negative"
- *
- * If you are building an application which tries to use an already
- * built c-ares library and you are getting this kind of errors on
- * this file, it is a clear indication that there is a mismatch between
- * how the library was built and how you are trying to use it for your
- * application. Your already compiled or binary library provider is the
- * only one who can give you the details you need to properly use it.

-.TH ARES_SAVE_OPTIONS 3 "5 March 2010"
-.SH NAME
-ares_save_options \- Save configuration values obtained from initialized ares_channel
-.SH SYNOPSIS
-.nf
-.B #include <ares.h>
-.PP
-.B int ares_save_options(ares_channel \fIchannel\fP, struct ares_options *\fIoptions\fP, int *\fIoptmask\fP)
-.fi
-.SH DESCRIPTION
-The \fBares_save_options(3)\fP function saves the channel data identified by
-.IR channel ,
-into the options struct identified by
-.IR options ,
-and saves the mask of options which are set to the integer
-pointer (passed by reference) identified by
-.IR optmask .
-
-The resultant options and optmask are then able to be
-passed directly to ares_init_options. When the options
-are no longer needed, ares_destroy_options should be called
-to free any associated memory.
-.SH RETURN VALUES
-.B ares_save_options(3)
-can return any of the following values:
-.TP 15
-.B ARES_SUCCESS
-The channel data was successfuly stored
-.TP 15
-.B ARES_ENOMEM
-The memory was exhausted
-.TP 15
-.B ARES_ENODATA
-The channel data identified by
-.IR channel
-were invalid.
-.SH NOTE
-Since c-ares 1.6.0 the ares_options struct has been "locked" meaning that it
-won't be extended to cover new functions. This function will remain
-functioning, but it can only return config data that can be represented in
-this config struct, which may no longer be the complete set of config
-options. \fBares_dup(3)\fP will not have that restriction.
-
-The ares_options struct can not handle potential IPv6 name servers the
-ares_channel might be configured to use. Function \fBares_save_options(3)\fP
-will only return IPv4 servers if any. In order to retrieve all name servers
-an ares_channel might be using, function \fBares_get_servers(3)\fP must be
-used instead.
-.SH SEE ALSO
-.BR ares_destroy_options (3),
-.BR ares_init_options (3),
-.BR ares_get_servers (3),
-.BR ares_dup (3)
-.SH AVAILABILITY
-ares_save_options(3) was added in c-ares 1.4.0

-.TH ARES_SEARCH 3 "24 July 1998"
-.SH NAME
-ares_search \- Initiate a DNS query with domain search
-.SH SYNOPSIS
-.nf
-.B #include <ares.h>
-.PP
-.B typedef void (*ares_callback)(void *\fIarg\fP, int \fIstatus\fP,
-.B int \fItimeouts\fP, unsigned char *\fIabuf\fP, int \fIalen\fP)
-.PP
-.B void ares_search(ares_channel \fIchannel\fP, const char *\fIname\fP,
-.B int \fIdnsclass\fP, int \fItype\fP, ares_callback \fIcallback\fP,
-.B void *\fIarg\fP)
-.fi
-.SH DESCRIPTION
-The
-.B ares_search
-function initiates a series of single-question DNS queries on the name
-service channel identified by
-.IR channel ,
-using the channel's search domains as well as a host alias file given
-by the HOSTALIAS environment variable. The parameter
-.I name
-gives the alias name or the base of the query name as a NUL-terminated
-C string of period-separated labels; if it ends with a period, the
-channel's search domains will not be used. Periods and backslashes
-within a label must be escaped with a backslash. The parameters
-.I dnsclass
-and
-.I type
-give the class and type of the query using the values defined in
-.BR <arpa/nameser.h> .
-When the query sequence is complete or has failed, the ares library
-will invoke
-.IR callback .
-Completion or failure of the query sequence may happen immediately, or
-may happen during a later call to
-.BR ares_process (3)
-or
-.BR ares_destroy (3).
-.PP
-The callback argument
-.I arg
-is copied from the
-.B ares_search
-argument
-.IR arg .
-The callback argument
-.I status
-indicates whether the query sequence ended with a successful query
-and, if not, how the query sequence failed. It may have any of the
-following values:
-.TP 19
-.B ARES_SUCCESS
-A query completed successfully.
-.TP 19
-.B ARES_ENODATA
-No query completed successfully; when the query was tried without a
-search domain appended, a response was returned with no answers.
-.TP 19
-.B ARES_EFORMERR
-A query completed but the server claimed that the query was
-malformatted.
-.TP 19
-.B ARES_ESERVFAIL
-No query completed successfully; when the query was tried without a
-search domain appended, the server claimed to have experienced a
-failure. (This code can only occur if the
-.B ARES_FLAG_NOCHECKRESP
-flag was specified at channel initialization time; otherwise, such
-responses are ignored at the
-.BR ares_send (3)
-level.)
-.TP 19
-.B ARES_ENOTFOUND
-No query completed successfully; when the query was tried without a
-search domain appended, the server reported that the queried-for
-domain name was not found.
-.TP 19
-.B ARES_ENOTIMP
-A query completed but the server does not implement the operation
-requested by the query. (This code can only occur if the
-.B ARES_FLAG_NOCHECKRESP
-flag was specified at channel initialization time; otherwise, such
-responses are ignored at the
-.BR ares_send (3)
-level.)
-.TP 19
-.B ARES_EREFUSED
-A query completed but the server refused the query. (This code can
-only occur returned if the
-.B ARES_FLAG_NOCHECKRESP
-flag was specified at channel initialization time; otherwise, such
-responses are ignored at the
-.BR ares_send (3)
-level.)
-.TP 19
-.B ARES_TIMEOUT
-No name servers responded to a query within the timeout period.
-.TP 19
-.B ARES_ECONNREFUSED
-No name servers could be contacted.
-.TP 19
-.B ARES_ENOMEM
-Memory was exhausted.
-.TP 19
-.B ARES_EDESTRUCTION
-The name service channel
-.I channel
-is being destroyed; the query will not be completed.
-.PP
-The callback argument
-.I timeouts
-reports how many times a query timed out during the execution of the
-given request.
-.PP
-If a query completed successfully, the callback argument
-.I abuf
-points to a result buffer of length
-.IR alen .
-If the query did not complete successfully,
-.I abuf
-will usually be NULL and
-.I alen
-will usually be 0, but in some cases an unsuccessful query result may
-be placed in
-.IR abuf .

-.TH ARES_SEND 3 "25 July 1998"
-.SH NAME
-ares_send \- Initiate a DNS query
-.SH SYNOPSIS
-.nf
-.B #include <ares.h>
-.PP
-.B typedef void (*ares_callback)(void *\fIarg\fP, int \fIstatus\fP,
-.B int \fItimeouts\fP, unsigned char *\fIabuf\fP, int \fIalen\fP)
-.PP
-.B void ares_send(ares_channel \fIchannel\fP, const unsigned char *\fIqbuf\fP,
-.B int \fIqlen\fP, ares_callback \fIcallback\fP, void *\fIarg\fP)
-.fi
-.SH DESCRIPTION
-The
-.B ares_send
-function initiates a DNS query on the name service channel identified
-by
-.IR channel .
-The parameters
-.I qbuf
-and
-.I qlen
-give the DNS query, which should already have been formatted according
-to the DNS protocol. When the query is complete or has failed, the
-ares library will invoke
-.IR callback .
-Completion or failure of the query may happen immediately, or may
-happen during a later call to
-.BR ares_process (3)
-or
-.BR ares_destroy (3).
-.PP
-The callback argument
-.I arg
-is copied from the
-.B ares_send
-argument
-.IR arg .
-The callback argument
-.I status
-indicates whether the query succeeded and, if not, how it failed. It
-may have any of the following values:
-.TP 19
-.B ARES_SUCCESS
-The query completed.
-.TP 19
-.B ARES_EBADQUERY
-The query buffer was poorly formed (was not long enough for a DNS
-header or was too long for TCP transmission).
-.TP 19
-.B ARES_ETIMEOUT
-No name servers responded within the timeout period.
-.TP 19
-.B ARES_ECONNREFUSED
-No name servers could be contacted.
-.TP 19
-.B ARES_ENOMEM
-Memory was exhausted.
-.TP 19
-.B ARES_EDESTRUCTION
-The name service channel
-.I channel
-is being destroyed; the query will not be completed.
-.PP
-The callback argument
-.I timeouts
-reports how many times a query timed out during the execution of the
-given request.
-.PP
-If the query completed, the callback argument
-.I abuf
-points to a result buffer of length
-.IR alen .
-If the query did not complete,
-.I abuf
-will be NULL and
-.I alen
-will be 0.
-.PP
-Unless the flag
-.B ARES_FLAG_NOCHECKRESP
-was set at channel initialization time,
-.B ares_send
-will normally ignore responses whose questions do not match the
-questions in
-.IR qbuf ,
-as well as responses with reply codes of
-.BR SERVFAIL ,
-.BR NOTIMP ,
-and
-.BR REFUSED .
-Unlike other query functions in the ares library, however,
-.B ares_send
-does not inspect the header of the reply packet to determine the error
-status, so a callback status of
-.B ARES_SUCCESS
-does not reflect as much about the response as for other query
-functions.

-.TH ARES_SET_SERVERS 3 "5 March 2010"
-.SH NAME
-ares_set_servers \- Initialize an ares_channel name servers configuration
-.SH SYNOPSIS
-.nf
-.B #include <ares.h>
-.PP
-.B int ares_set_servers(ares_channel \fIchannel\fP, struct ares_addr_node *\fIservers\fP)
-.fi
-.SH DESCRIPTION
-The \fBares_set_servers(3)\fP function initializes name servers configuration
-for the channel data identified by
-.IR channel ,
-from a
-.IR servers
-pointer to a linked list of ares_addr_node structs holding name servers
-address data.
-
-The name server linked list pointer argument may be the result of a previous
-call to \fBares_get_servers(3)\fP or a linked list of ares_addr_node structs
-setup by other means.
-
-This function replaces any potentially previously configured name servers
-with the ones given in the linked list. So, in order to configure a channel
-with more than one name server all the desired ones must be specified in a
-single list.
-
-\fBares_set_servers(3)\fP does not take ownership of the linked list argument.
-The caller is responsible to free the linked list when no longer needed.
-
-This function is capable of handling IPv4 and IPv6 name server
-addresses simultaneously, rendering \fBares_init_options(3)\fP with
-optmask \fBARES_OPT_SERVERS\fP functionally obsolete except for
-IPv4-only name server usage.
-
-.SH RETURN VALUES
-.B ares_set_servers(3)
-may return any of the following values:
-.TP 15
-.B ARES_SUCCESS
-The name servers configuration was successfuly initialized.
-.TP 15
-.B ARES_ENOMEM
-The process's available memory was exhausted.
-.TP 15
-.B ARES_ENODATA
-The channel data identified by
-.IR channel
-was invalid.
-.TP 15
-.B ARES_ENOTINITIALIZED
-c-ares library initialization not yet performed.

-.SH DESCRIPTION
-.PP
-This function sets a \fIcallback\fP in the given ares channel handle. This
-callback function will be invoked after the socket has been created, and
-connected to the remote server. The callback must return ARES_SUCCESS if
-things are fine, or use the standard ares error codes to signal errors
-back. Returned errors will abort the ares operation.
