release: 7.21.0

There is an implicit conversion from "unsigned long" to "long";
rounding, sign extension, or loss of accuracy may result.

Fixed by an added typecast.

+# Google Android makefile for curl and libcurl
+#
+# Place the curl source (including this makefile) into external/curl/ in the
+# Android source tree.  Then build them with 'make curl' or just 'make 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. The only way I've found to do this is tricky. Perform a
+# normal Android build with libcurl in the source tree, providing the target
+# "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 -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.
+#
+# The end result will be a configure command that looks something like this
+# (the environment variable A is set to the Android root path):
+#
+#  A=`realpath ../..` && \
+#  PATH="$A/prebuilt/linux-x86/toolchain/arm-eabi-X/bin:$PATH" \
+#  ./configure --host=arm-linux CC=arm-eabi-gcc \
+#  CPPFLAGS="-I $A/system/core/include ..." \
+#  CFLAGS="-nostdlib -fno-exceptions -Wno-multichar ..." \
+#  LIB="$A/prebuilt/linux-x86/toolchain/arm-eabi-X/lib/gcc/arm-eabi/X\
+#  /interwork/libgcc.a ..." \
+#
+# Finally, copy the file COPYING to NOTICE so that the curl license gets put
+# into the right place (see the note about this below).

+# Add full (4 or 5 libs) SSL support
+# Add INSTALL target (EXTRA_DIST variables in Makefile.am may be moved to Makefile.inc so that CMake/CPack is aware of what's to include).
+# Add CTests(?)
+# Check on all possible platforms
+# Test with as many configurations possible (With or without any option)
+# Create scripts that help keeping the CMake build system up to date (to reduce maintenance). According to Tetetest:
+#  - lists of headers that 'configure' checks for;
+#  - curl-specific tests (the ones that are in m4/curl-*.m4 files);
+#  - (most obvious thing:) curl version numbers.
+# Add documentation subproject
+#
+# To check:
+# (From Daniel Stenberg) The cmake build selected to run gcc with -fPIC on my box while the plain configure script did not.
+# (From Daniel Stenberg) The gcc command line use neither -g nor any -O options. As a developer, I also treasure our configure scripts's --enable-debug option that sets a long range of "picky" compiler options.

-  Changelog for the c-ares project
-
-* 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.

-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 repostitory.
-
-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:

-.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.

- * 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

-.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 .

-.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)

-.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 .

-.TH ARES_GETNAMEINFO 3 "16 May 2005"
-.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 	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

-.TH ARES_INIT 3 "13 May 2008"
-.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 communciations 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.
-.SH SEE ALSO
-.BR ares_destroy (3)

-.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)

-.SH NAME
-ares_parse_a_reply \- Parse a reply to a DNS query of type A into a hostent
-.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 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 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 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
-.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_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.

-.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
-.B ares_save_options
-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.
