RELEASE-NOTES: synced with a865bd9fba

The function that checks if pipelining is possible now requires the HTTP
bit to be set so that it doesn't mistakenly tries to do it for other
protocols.

Bug: http://curl.haxx.se/mail/lib-2010-12/0152.html
Reported by: Dmitri Shubin

 # Google Android makefile for curl and libcurl

+# from the Android root. Tested with Android 1.5 and 2.1
 #
 # Note: you must first create a curl_config.h file by running configure in the
-# Android environment. I haven't found an easy way to do this yet. If there is
+# Android environment. The only way I've found to do this is tricky. Perform a
-# no easy way, a static config-android.h may need to be created and checked in

+# "showcommands" to make. The build will eventually fail (because curl_config.h
+# doesn't exist yet), but the compiler commands used to build curl will be
+# shown. Now, from the external/curl/ directory, run curl's normal configure
+# command with flags that match what Android itself uses. This will mean
+# putting the compiler directory into the PATH, putting the -I, -isystem and
+# -D options into CPPFLAGS, putting the -W, -m, -f, -O and -nostdlib options
+# into CFLAGS, and putting the -Wl, -L and -l options into LIBS, along with the
+# path to the files libgcc.a, crtbegin_dynamic.o, and ccrtend_android.o.
+# Remember that the paths must be absolute since you will not be running
+# configure from the same directory as the Android make.  The normal
+# cross-compiler options must also be set. Note that the -c, -o, -MD and
+# similar flags must not be set.
+#
+# To see all the LIBS options, you'll need to do the "showcommands" trick on an
+# executable that's already buildable and watch what flags Android uses to link
+# it (dhcpcd is a good choice to watch). You'll also want to add -L options to
+# LIBS that point to the out/.../obj/lib/ and out/.../obj/system/lib/
+# directories so that additional libraries can be found and used by curl.
+#
+# The end result will be a configure command that looks something like this
+# (the environment variable A is set to the Android root path which makes the
+# command shorter):
+#
+#  A=`realpath ../..` && \
+#  PATH="$A/prebuilt/linux-x86/toolchain/arm-eabi-X/bin:$PATH" \

-  Changelog for the c-ares project
-
-* 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 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.
-
-* 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 1.6.1 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 1.6.1 on all systems.
-
-  In order to use c-ares 1.6.1 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 1.6.1 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 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
-- G<>nter 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
-
-* Imported the sources from ares 1.1.1

-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.

ares/README

@@ -1,46 +0,0 @@
-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.

-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 1.6.1 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 dependant 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 */
-

-This is what's new and changed in the c-ares 1.6.1 release:
-
-Changed:
-
- o in6_addr is not used in ares.h anymore, but a private ares_in6_addr is
-   instead declared and used
- o ares_gethostbyname() now supports 'AF_UNSPEC' as a family for resolving
-   either AF_INET6 or AF_INET
- o a build-time configured ares_socklen_t is now used instead of socklen_t
- o new ares_library_init() and ares_library_cleanup() functions
- o new --enable-curldebug configure option
- o ARES_ECANCELLED is now sent as reason for ares_cancel()
-
-Fixed:
-
- o ares_parse_*_reply() functions now return ARES_EBADRESP instead of
-   ARES_EBADNAME if the name in the response failed to decode
- o only expose/export symbols starting with 'ares_'
- o fix \Device\TCP handle leaks triggered by buggy iphlpapi.dll
- o init without internet gone no longer fails
-
-Thanks go to these friendly people for their efforts and contributions:
-
- Phil Blundell, Japheth Cleaver, Yang Tse, Gregor Jasny, Joshua Kwan,
- Timo Teras
-
-Have fun!

-ares_gethostbyname

-- When built to support IPv6, it needs to also support PF_UNSPEC or similar,
-  so that an application can ask for any protocol and then c-ares would return
-  all known resolves and not just explicitly IPv4 _or_ IPv6 resolves.
-
-ares_process

-- Upon next ABI breakage ares_process() should be changed to return 'int'

-ares_cancel \- Cancel a resolve
-.SH SYNOPSIS
-.nf
-.B #include <ares.h>
-.PP
-.B int 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

-.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 .

-.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 \fIchannel\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.

-.TH ARES_EXPAND_NAME 3 "23 July 1998"
-.SH NAME
-ares_expand_name \- Expand a DNS-encoded domain name
-.SH SYNOPSIS
-.nf
-.B #include <ares.h>
-.PP
-.B int ares_expand_name(const unsigned char *\fIencoded\fP,
-.B      const unsigned char *\fIabuf\fP, int \fIalen\fP, char **\fIs\fP,
-.B 	int *\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.

- * In the simple case, an encoded name is a series of labels, each
- * composed of a one-byte length (limited to values between 0 and 63
- * inclusive) followed by the label contents.  The name is terminated
- * by a zero-length label.
- *
- * In the more complicated case, a label may be terminated by an
- * indirection pointer, specified by two bytes with the high bits of
- * the first byte (corresponding to INDIR_MASK) set to 11.  With the
- * two high bits of the first byte stripped off, the indirection
- * pointer gives an offset from the beginning of the containing
- * message with more labels to decode.  Indirection can happen an
- * arbitrary number of times, so we have to detect loops.
- *
- * Since the expanded name uses '.' as a label separator, we use
- * backslashes to escape periods or backslashes in the expanded name.

-.TH ARES_EXPAND_NAME 3 "23 July 1998"
-.SH NAME
-ares_expand_string \- Expand a length encoded string
-.SH SYNOPSIS
-.nf
-.B #include <ares.h>
-.PP
-.B int ares_expand_string(const unsigned char *\fIencoded\fP,
-.B      const unsigned char *\fIabuf\fP, int \fIalen\fP, unsigned char **\fIs\fP,
-.B 	int *\fIenclen\fP)
-.fi
-.SH DESCRIPTION
-The
-.B ares_expand_string
-function converts a length encoded string to a NUL-terminated C
-string.  The argument
-.I encoded
-gives the beginning of the encoded string, 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 string is stored in the variable pointed to by
-.I enclen
-so that the caller can advance past the encoded string to read
-further data in the message.
-.SH RETURN VALUES
-.B ares_expand_string
-can return any of the following values:
-.TP 15
-.B ARES_SUCCESS
-Expansion of the encoded string succeeded.
-.TP 15
-.B ARES_EBADSTR
-The encoded string was malformed and could not be expanded.
-.TP 15
-.B ARES_ENOMEM
-Memory was exhausted.

-.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 SEE ALSO
-.BR ares_process (3),
-.BR ares_gethostbyaddr (3)

-.TH ARES_GETHOSTBYNAME 3 "25 July 1998"
-.SH NAME
-ares_gethostbyname_file \- Lookup a name in the system's hosts file
-.SH SYNOPSIS
-.nf
-.B #include <ares.h>
-.PP
-.B void 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 .
-.SH AVAILABILITY
-Added in c-ares 1.5.4

-.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 "22 December 2005"
-.SH NAME
-ares_getsock \- get file descriptors to wait on
-.SH SYNOPSIS
-.nf
-.B #include <ares.h>
-.PP
-.B int ares_getsock(ares_channel \fIchannel\fP, int *\fIsocks\fP, 
-.B int \fInumsocks\fP);
-.fi
-.SH DESCRIPTION
-The
-.B ares_getsock
-function retrieves the set of file 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 .
-File descriptors will be set in the integer 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) + \
-                                         ARES_GETSOCK_MAXNUM)))
-.fi
-.SH NOTES
-This function was added in c-ares 1.3.1
-.SH SEE ALSO

-.TH ARES_INIT 3 "26 May 2009"
-.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 *\fIchannel\fP)
-.B int ares_init_options(ares_channel *\fIchannel\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 \fIchannel\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 servers to contact, instead of the servers specified in
-resolv.conf or the local named.
-.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.

-.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 1.6.1 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 1.6.1 without calling
-\fIares_library_cleanup(3)\fP due to the fact that it is nearly a do-nothing
-function on non-Win32/64 platforms.

-.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.

-.TH ARES_MKQUERY 3 "4 January 2000"
-.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, 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)

-.TH ARES_PARSE_AAAA_REPLY 3 "10 March 2005"
-.SH NAME
-ares_parse_aaaa_reply \- Parse a reply to a DNS query of type AAAA into a hostent
-.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 addrttl *\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 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 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.
-.SH SEE ALSO
-.BR ares_gethostbyname (3),
-.BR ares_free_hostent (3)

-.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
- * dependant 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 "1 June 2007"
-.SH NAME
-ares_save_options \- Save configuration values obtained from initialized ares_channel
-.SH SYNOPSIS
-.nf
-.B #include <ares.h>
-.PP
-.B void 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 NOTE
-Since c-ares 1.6.0 the ares_options struct has been "locked" meaning that it
-won't be extended to cover new funtions. 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.
-.SH SEE ALSO
-.BR ares_destroy_options (3),
-.BR ares_init_options (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 .
