+
+Version 1.7.1 (Mar 23, 2010)
+
+* May 31, 2010 (Jakub Hrozek)
+- Use the last instance of domain/search, not the first one
+
+* March 23, 2010 (Daniel Stenberg)
+- We switched from CVS to git. See http://github.com/bagder/c-ares
+
+* March 5, 2010 (Daniel Stenberg)
+- Daniel Johnson provided fixes for building with the clang compiler.
+
+* March 5, 2010 (Yang Tse)
+- Added IPv6 name servers support. Implementation has been based on code,
+  comments and feedback provided November and December of 2008 by Daniel
+  Stenberg, Gregor Jasny, Phil Blundell and myself, December 2009 by Cedric
+  Bail, and February 2010 by Jakub Hrozek on the c-ares mailing list. On
+  March I reviewed all that, selected the best of each, and adjusted or
+  extended parts of it to make the best fit.
+
+  The external and visible result of all this is that two new functions are
+  added to the external API, ares_get_servers() and ares_set_servers(), which
+  becomes now the preferred way of getting and setting name servers for any
+  ares channel as these support both IPv4 and IPv6 name servers.
+
+  In order to not break ABI compatibility, ares_init_options() with option
+  mask ARES_OPT_SERVERS and ares_save_options() may still be used in code
+  which is intended to run on IPv4-only stacks. But remember that these
+  functions do not support IPv6 name servers. This implies that if the user
+  is capable of defining or providing an IPv6 name server, and the app is
+  using ares_init_options() or ares_save_options() at some point to handle
+  the name servers, the app will likely lose IPv6 name servers.
+
+* January 28, 2010 (Daniel Stenberg)
+- Tommie Gannert pointed out a silly bug in ares_process_fd() since it didn't
+  check for broken connections like ares_process() did. Based on that, I
+  merged the two functions into a single generic one with two front-ends.
+
+* December 29, 2009 (Yang Tse)
+- Laszlo Tamas Szabo adjusted Makefile.msvc compiler options so that where
+  run-time error checks enabling compiler option /GZ was used it is replaced
+  with equivalent /RTCsu for Visual Studio 2003 and newer versions. Option
+  /GX is replaced with equivalent /EHsc for all versions. Also fixed socket
+  data type for internal configure_socket function.
+
+* December 21, 2009 (Yang Tse)
+- Ingmar Runge noticed that Windows config-win32.h configuration file
+  did not include a definition for HAVE_CLOSESOCKET which resulted in
+  function close() being inappropriately used to close sockets.
+
+Version 1.7.0 (Nov 30, 2009)
+
+* November 26, 2009 (Yang Tse)
+- Larry Lansing fixed ares_parse_srv_reply to properly parse replies
+  which might contain non-SRV answers, skipping over potential non-SRV
+  ones such as CNAMEs.
+
+* November 23, 2009 (Yang Tse)
+- Changed naming convention for c-ares libraries built with MSVC, details
+  and build instructions provided in README.msvc file.
+
+* November 22, 2009 (Yang Tse)
+- Jakub Hrozek fixed more function prototypes in man pages to sync them
+  with the ones declared in ares.h
+
+- Jakub Hrozek renamed addrttl and addr6ttl structs to ares_addrttl and
+  ares_addr6ttl in order to prevent name space pollution, along with
+  necessary changes to code base and man pages.This change does not break
+  ABI, there is no need to recompile existing applications. But existing
+  applications using these structs with the old name will need source code
+  adjustments when recompiled using c-ares 1.7.0.
+
+* November 21, 2009 (Yang Tse)
+- Added manifest stuff to Makefile.msvc.
+
+* November 20, 2009 (Yang Tse)
+- Fixed several function prototypes in man pages that were out of sync
+  with the ones declared in ares.h.  Added ares_free_data() along with
+  man page.  Updated ares_parse_srv_reply() and ares_parse_txt_reply()
+  with changes from Jakub Hrozek making these now return linked lists
+  instead of arrays, and merging the ares_free_data() adjustments.
+
+* November 10, 2009 (Yang Tse)
+- Updated MSVC 6.0 project files to match settings from Makefile.msvc.
+
+* November 9, 2009 (Yang Tse)
+- Makefile.msvc is now the reference method to build c-ares and sample
+  programs with any MSVC compiler or MS Visual Studio version.  If no
+  option or target are specified it builds dynamic and static c-ares
+  libraries in debug and release flavours and also builds all sample
+  programs using each of the different c-ares libraries.
+
+* November 2, 2009 (Yang Tse)
+- Renamed c-ares setup.h to ares_setup.h
+
+* October 31, 2009 (Yang Tse)
+- Symbol hiding configure options are named now --enable-symbol-hiding
+  and --disable-symbol-hiding in an attempt to make them less ambiguous.
+
+* October 30, 2009 (Yang Tse)
+- Many fixes for ares_parse_txt_reply()
+
+* October 29, 2009 (Daniel Stenberg)
+- Jakub Hrozek added ares_parse_txt_reply() for TXT parsing
+
+* October 29, 2009 (Yang Tse)
+- Updated MSVC 6.0 workspace and project files that allows building
+  dynamic and static c-ares libraries in debug and release flavours.
+  Additionally each of the three sample programs is built against
+  each of the four possible c-ares libraries, generating all this
+  a total number of 12 executables and 4 libraries.
+
+* October 28, 2009 (Yang Tse)
+- Initial step towards the ability to reduce c-ares exported symbols
+  when built as a shared library based on the 'visibility' attribute
+  for GNUC and Intel compilers and based on __global for Sun compilers,
+  taking also in account __declspec function decoration for Win32 and
+  Symbian DLL's.
+
+* October 27, 2009 (Yang Tse)
+- Fixed Pelles C Win32 target compilation issues.
+
+* October 23, 2009 (Yang Tse)
+- John Engelhart noticed an unreleased problem relative to a duplicate
+  ARES_ECANCELLED error code value and missing error code description.
+
+* October 7, 2009 (Yang Tse)
+- Overhauled ares__get_hostent() Fixing out of bounds memory overwrite
+  triggered with malformed /etc/hosts file. Improving parsing of /etc/hosts
+  file. Validating requested address family. Ensuring that failures always
+  return a NULL pointer. Adjusting header inclusions.
+
+* October 6, 2009 (Yang Tse)
+- Fix ssize_t redefinition errors on WIN64 reported by Alexey Simak.
+
+* September 29, 2009 (Yang Tse)
+- Make configure script also check if _REENTRANT definition is required to
+  make errno available as a preprocessor macro.
+
+* September 7, 2009 (Yang Tse)
+- Add T_SRV portability check to ares_parse_srv_reply.c
+
+* 4 Sep 2009 (Daniel Stenberg)
+- Jakub Hrozek added ares_parse_srv_reply() for SRV parsing
+
+* 3 Aug 2009 (Daniel Stenberg)
+- Joshua Kwan fixed the init routine to fill in the defaults for stuff that
+  fails to get inited by other means. This fixes a case of when the c-ares
+  init fails when internet access is fone.
+
+- Timo Teras changed the reason code used in the resolve callback done when
+  ares_cancel() is used, to be ARES_ECANCELLED instead of ARES_ETIMEOUT to
+  better allow the callback to know what's happening.
+
+* 14 Jul 2009 (Guenter Knauf)
+- renamed generated config.h to ares_config.h to avoid any future clashes
+  with config.h from other projects.
+
+* June 20 2009 (Yang Tse)
+- Refactor how libraries are checked for connect() function in configure
+  script and check for connect() as it is done for other functions.
+
+* June 19 2009 (Yang Tse)
+- Make sclose() function-like macro definition used to close a socket,
+  now solely based on HAVE_CLOSESOCKET and HAVE_CLOSESOCKET_CAMEL
+  config file preprocessor definitions
+
+* June 18 2009 (Yang Tse)
+- Add CloseSocket camel case function check for configure script.
+
+* June 17 2009 (Yang Tse)
+- Check for socket() and closesocket() as it is done for other functions
+  in configure script.
+
+* June 11 2009 (Yang Tse)
+- Modified buildconf so that when automake runs it copies missing files
+  instead of symlinking them.
+
+* June 8 2009 (Yang Tse)
+- Removed buildconf.bat from release and daily snapshot archives. This
+  file is only for CVS tree checkout builds.
+
+* May 26 2009 (Yang Tse)
+- Added --enable-curldebug configure option to enable and disable building
+  with the low-level curl debug memory tracking 'feature' to allow decoupled
+  setting from --enable-debug, allowing again to build c-ares independently
+  out of the CVS tree.
+
+  For the c-ares library option --enable-debug enables debug build features
+  which are _not_ related with memory tracking. For the c-ares library when
+  --enable-debug is given it does not enable the memory tracking feature. If
+  you wish to enable the curl debug memory tracking you must use configure
+  option --enable-curldebug explicitily to do so.
+
+  Internally, definition of preprocessor symbol DEBUGBUILD restricts code
+  which is only compiled for debug enabled builds. And symbol CURLDEBUG is
+  used to differentiate code which is _only_ used for memory tracking.
+
+  Make ares_init(), ares_dup() and ares_init_options() fail returning
+  ARES_ENOTINITIALIZED if library initialization has not been performed
+  calling ares_library_init().
+
+* May 20 2009 (Yang Tse)
+- Added ares_library_init() and ares_library_cleanup() man pages.
+
+* May 19 2009 (Yang Tse)
+- Introduced ares_library_init() and ares_library_cleanup() functions.
+
+  This is an API and ABI break for Win32/64 systems. Non-Win32/64 build targets
+  using c-ares 1.7.0 can still survive without calling these functions. Read all
+  the details on ares_library_init(3) and ares_library_cleanup(3) man pages that
+  are included.
+
+  curl/libcurl 7.19.5 is fully compatible with c-ares 1.7.0 on all systems.
+
+  In order to use c-ares 1.7.0 with curl/libcurl on Win32/64 systems it is
+  required that curl/libcurl is 7.19.5 or newer. In other words, it is not
+  possible on Win32/64 to use c-ares 1.7.0 with a curl/libcurl version less
+  than 7.19.5
+
+* May 11 2009 (Daniel Stenberg)
+- Gregor Jasny made c-ares link with libtool 's -export-symbols-regex option to
+  only expose functions starting with ares_.
+
+* May 7 2009 (Yang Tse)
+- Fix an m4 overquoting triggering a spurious 'AS_TR_CPP' symbol definition
+  attempt in generated config.h
+
+* May 2 2009 (Yang Tse)
+- Use a build-time configured ares_socklen_t data type instead of socklen_t.
+
+* April 21 2009 (Yang Tse)
+- Moved potential inclusion of system's malloc.h and memory.h header files to
+  setup_once.h.  Inclusion of each header file is based on the definition of
+  NEED_MALLOC_H and NEED_MEMORY_H respectively.
+
+* March 11 2009 (Yang Tse)
+- Japheth Cleaver fixed acountry.c replacing u_long with unsigned long.
+
+* February 20 2009 (Yang Tse)
+- Do not halt compilation when using VS2008 to build a Windows 2000 target.
+
+* February 3 2009 (Phil Blundell)
+- If the server returns garbage or nothing at all in response to an AAAA query,
+  go on and ask for A records anyway.
+
+* January 31 2009 (Daniel Stenberg)
+- ares_gethostbyname() now accepts 'AF_UNSPEC' as a family for resolving
+  either AF_INET6 or AF_INET. It works by accepting any of the looksups in the
+  hosts file, and it resolves the AAAA field with a fallback to A.
+
+* January 14 2009 (Daniel Stenberg)
+- ares.h no longer uses the HAVE_STRUCT_IN6_ADDR define check, but instead it
+  now declares the private struct ares_in6_addr for all systems instead of
+  relying on one possibly not present in the system.
+
+* January 13 2009 (Phil Blundell)
+- ares__send_query() now varies the retry timeout pseudo-randomly to avoid
+  packet storms when several queries were started at the same time.
+
+* January 11 2009 (Daniel Stenberg)
+- Phil Blundell added the internal function ares__expand_name_for_response()
+  that is now used by the ares_parse_*_reply() functions instead of the
+  ares_expand_name() simply to easier return ARES_EBADRESP for the cases where
+  the name expansion fails as in responses that really isn't expected.
+
+Version 1.6.0 (Dec 9, 2008)
+
+* December 9 2008 (Gisle Vanem)
+
+  Fixes for Win32 targets using the Watt-32 tcp/ip stack.
+
+* Dec 4 2008 (Daniel Stenberg)
+
+  Gregor Jasny provided the patch that introduces ares_set_socket_callback(),
+  and I edited it to also get duped by ares_dup().
+
+* Dec 3 2008 (Daniel Stenberg)
+
+  API changes:
+
+  I made sure the public ares_config struct looks like before and yet it
+  supports the ROTATE option thanks to c-ares now storing the "optmask"
+  internally. Thus we should be ABI compatible with the past release(s)
+  now. My efforts mentioned below should not break backwards ABI compliance.
+
+  Here's how I suggest we proceed with the API:
+
+  ares_init() will be primary "channel creator" function.
+
+  ares_init_options() will continue to work exactly like now and before. For
+  starters, it will be the (only) way to set the existing options.
+
+  ares_save_options() will continue to work like today, but will ONLY save
+  options that you can set today (including ARES_OPT_ROTATE actually) but new
+  options that we add may not be saved with this.
+
+  Instead we introduce:
+
+  ares_dup() that instead can make a new channel and clone the config used
+  from an existing channel. It will then clone all config options, including
+  future new things we add.
+
+  ares_set_*() style functions that set (new) config options. As a start we
+  simply add these for new functionality, but over time we can also introduce
+  them for existing "struct ares_options" so that we can eventually deprecate
+  the two ares_*_options() functions.
+
+  ares_get_*() style functions for extracting info from a channel handle that
+  should be used instead of ares_save_options().
+
+* Nov 26 2008 (Yang Tse)
+- Brad Spencer provided changes to allow buildconf to work on OS X.
+
+- Gerald Combs fixed a bug in ares_parse_ptr_reply() which would cause a
+  buffer to shrink instead of expand if a reply contained 8 or more records.
+
+* Nov 25 2008 (Yang Tse)
+- In preparation for the upcomming IPv6 nameservers patch, the internal
+  ares_addr union is now changed into an internal struct which also holds
+  the address family.
+
+* Nov 19 2008 (Daniel Stenberg)
+- Brad Spencer brought the new function ares_gethostbyname_file() which simply
+  resolves a host name from the given file, using the regular hosts syntax.
+
+* Nov 1 2008 (Daniel Stenberg)
+- Carlo Contavalli added support for the glibc "rotate" option, as documented
+  in man resolv.conf:
+
+  causes round robin selection of nameservers from among those listed.  This
+  has the effect of spreading the query load among all listed servers, rather
+  than having all clients try the first listed server first every time.
+
+  You can enable it with ARES_OPT_ROTATE
+
+* Oct 21 2008 (Yang Tse)
+  Charles Hardin added handling of EINPROGRESS for UDP connects.
+
+* Oct 18 2008 (Daniel Stenberg)
+  Charles Hardin made adig support a regular numerical dotted IP address for the
+  -s option as well.
+
+* Oct 7 2008 (Yang Tse)
+- Added --enable-optimize configure option to enable and disable compiler
+  optimizations to allow decoupled setting from --enable-debug.
+
+* Oct 2 2008 (Yang Tse)
+- Added --enable-warnings configure option to enable and disable strict
+  compiler warnings to allow decoupled setting from --enable-debug.
+
+* Sep 17 2008 (Yang Tse)
+- Code reorganization to allow internal/private use of "nameser.h" to any
+  system that lacks arpa/nameser.h or arpa/nameser_compat.h header files.
+
+* Sep 16 2008 (Yang Tse)
+- Code reorganization to allow internal/private use of ares_writev to any
+  system that lacks the writev function.
+
+* Sep 15 2008 (Yang Tse)
+- Code reorganization to allow internal/private use of ares_strcasecmp to any
+  system that lacks the strcasecmp function.
+
+- Improve configure detection of some string functions.
+
+* Sep 11 2008 (Yang Tse)
+- Code reorganization to allow internal/private use of ares_strdup to any
+  system that lacks the strdup function.
+
+Version 1.5.3 (Aug 29, 2008)
+
+* Aug 25 2008 (Yang Tse)
+- Improvement by Brad House:
+
+  This patch addresses an issue in which a response could be sent back to the
+  source port of a client from a different address than the request was made to.
+  This is one form of a DNS cache poisoning attack.
+
+  The patch simply uses recvfrom() rather than recv() and validates that the
+  address returned from recvfrom() matches the address of the server we have
+  connected to. Only necessary on UDP sockets as they are connection-less, TCP
+  is unaffected.
+
+- Fix by George Neill:
+  Fixed compilation of acountry sample application failure on some systems.
+
+* Aug 4 2008 (Daniel Stenberg)
+- Fix by Tofu Linden:
+
+  The symptom:
+  * Users (usually, but not always) on 2-Wire routers and the Comcast service
+  and a wired connection to their router would find that the second and
+  subsequent DNS lookups from fresh processes using c-ares to resolve the same
+  address would cause the process to never see a reply (it keeps polling for
+  around 1m15s before giving up).
+
+  The repro:
+  * On such a machine (and yeah, it took us a lot of QA to find the systems
+  that reproduce such a specific problem!), do 'ahost www.secondlife.com',
+  then do it again.  The first process's lookup will work, subsequent lookups
+  will time-out and fail.
+
+  The cause:
+  * init_id_key() was calling randomize_key() *before* it initialized
+  key->state, meaning that the randomness generated by randomize_key() is
+  immediately overwritten with deterministic values. (/dev/urandom was also
+  being read incorrectly in the c-ares version we were using, but this was
+  fixed in a later version.)
+  * This makes the stream of generated query-IDs from any new c-ares process
+  be an identical and predictable sequence of IDs.
+  * This makes the 2-Wire's default built-in DNS server detect these queries
+  as probable-duplicates and (erroneously) not respond at all.
+
+
+* Aug 4 2008 (Yang Tse)
+- Autoconf 2.62 has changed the behaviour of the AC_AIX macro which we use.
+  Prior versions of autoconf defined _ALL_SOURCE if _AIX was defined. 2.62
+  version of AC_AIX defines _ALL_SOURCE and other four preprocessor symbols
+  no matter if the system is AIX or not. To keep the traditional behaviour,
+  and an uniform one across autoconf versions AC_AIX is replaced with our
+  own internal macro CARES_CHECK_AIX_ALL_SOURCE.
+
+* Aug 1 2008 (Yang Tse)
+- Configure process now checks if the preprocessor _REENTRANT symbol is already
+  defined. If it isn't currently defined a set of checks are performed to test
+  if its definition is required to make visible to the compiler a set of *_r
+  functions. Finally, if _REENTRANT is already defined or needed it takes care
+  of making adjustments necessary to ensure that it is defined equally for the
+  configure process tests and generated config file.
+
+* Jul 20 2008 (Yang Tse)
+- When recvfrom prototype uses a void pointer for arguments 2, 5 or 6 this will
+  now cause the definition, as appropriate, of RECVFROM_TYPE_ARG2_IS_VOID,
+  RECVFROM_TYPE_ARG5_IS_VOID or RECVFROM_TYPE_ARG6_IS_VOID.
+
+* Jul 17 2008 (Yang Tse)
+- RECVFROM_TYPE_ARG2, RECVFROM_TYPE_ARG5 and RECVFROM_TYPE_ARG6 are now defined
+  to the data type pointed by its respective argument and not the pointer type.
+
+* Jul 16 2008 (Yang Tse)
+- Improved configure detection of number of arguments for getservbyport_r.
+  Detection is now based on compilation checks instead of linker ones.
+
+- Configure process now checks availability of recvfrom() socket function and
+  finds out its return type and the types of its arguments. Added definitions
+  for non-configure systems config files, and introduced macro sreadfrom which
+  will be used on udp sockets as a recvfrom() wrapper in the future.
+
+* Jul 15 2008 (Yang Tse)
+- Introduce definition of _REENTRANT symbol in setup.h to improve library
+  usability.  Previously the configure process only used the AC_SYS_LARGEFILE
+  macro for debug builds, now it is also used for non-debug ones enabling the
+  use of configure options --enable-largefile and --disable-largefile which
+  might be needed for library compatibility.  Remove checking the size of
+  curl_off_t, it is no longer needed.
+
+* Jul 3 2008 (Daniel Stenberg)
+- Phil Blundell: If you ask ares_gethostbyname() to do an AF_INET6 lookup and
+  the target host has only A records, it automatically falls back to an
+  AF_INET lookup and gives you the A results.  However, if the target host has
+  a CNAME record, this behaviour is defeated since the original query does
+  return some data even though ares_parse_aaa_reply() doesn't consider it
+  relevant. Here's a small patch to make it behave the same with and without
+  the CNAME.
+
+* Jul 2 2008 (Yang Tse)
+- Fallback to gettimeofday when monotonic clock is unavailable at run-time.
+
+* Jun 30 2008 (Daniel Stenberg)
+
+- As was pointed out to me by Andreas Schuldei, the MAXHOSTNAMELEN define is
+  not posix or anything and thus c-ares failed to build on hurd (and possibly
+  elsewhere). The define was also somewhat artificially used in the windows
+  port. Now, I instead rewrote the use of gethostbyname to enlarge the host
+  name buffer in case of need and totally avoid the use of the MAXHOSTNAMELEN
+  define. I thus also removed the defien from the namser.h file where it was
+  once added for the windows build.
+
+  I also fixed init_by_defaults() function to not leak memory in case if
+  error.
+
+* Jun 9 2008 (Yang Tse)
+
+- Make libcares.pc generated file for pkg-config include information relative
+  to the libraries needed for the static linking of c-ares.
+
+* May 30 2008 (Yang Tse)
+
+- Brad House fixed a missing header file inclusion in adig sample program.
+
+Version 1.5.2 (May 29, 2008)
+
+* May 13 2008 (Daniel Stenberg)
+
+- Introducing millisecond resolution support for the timeout option. See
+  ares_init_options()'s ARES_OPT_TIMEOUTMS.
+
+* May 9 2008 (Yang Tse)
+
+- Use monotonic time source if available, for private function ares__tvnow()
+
+* May 7 2008 (Daniel Stenberg)
+
+- Sebastian made c-ares able to return all PTR-records when doing reverse
+  lookups. It is not common practice to have multiple PTR-Records for a single
+  IP, but its perfectly legal and some sites have those.
+
+- Doug Goldstein provided a configure patch: updates autoconf 2.13 usage to
+  autoconf 2.57 usage (which is the version you have specified as the minimum
+  version). It's a minor change but it does clean up some warnings with newer
+  autoconf (specifically 2.62).
+
+* May 5 2008 (Yang Tse)
+
+- Improved parsing of resolver configuration files.
+
+* April 4 2008 (Daniel Stenberg)
+
+- Eino Tuominen improved the code when a file is used to seed the randomizer.
+
+- Alexey Simak made adig support NAPTR records
+
+- Alexey Simak fixed the VC dsp file by adding the missing source file
+  ares_expand_string.c
+
+* December 11 2007 (Gisle Vanem)
+
+- Added another sample application; acountry.c which converts an
+  IPv4-address(es) and/or host-name(s) to country-name and country-code.
+  This uses the service of the DNSBL at countries.nerd.dk.
+
+* December 3 2007 (Daniel Stenberg)
+
+- Brad Spencer fixed the configure script to assume that there's no
+  /dev/urandom when built cross-compiled as then the script cannot check for
+  it.
+
+- Erik Kline cleaned up ares_gethostbyaddr.c:next_lookup() somewhat
+
+Version 1.5.1 (Nov 21, 2007)
+
+* November 21 2007 (Daniel Stenberg)
+
+- Robin Cornelius pointed out that ares_llist.h was missing in the release
+  archive for 1.5.0
+
+Version 1.5.0 (Nov 21, 2007)
+
+* October 2 2007 (Daniel Stenberg)
+
+- ares_strerror() segfaulted if the input error number was out of the currently
+  supported range.
+
+- Yang Tse: Avoid a segfault when generating a DNS "Transaction ID" in
+  internal function init_id_key() under low memory conditions.
+
+* September 28 2007 (Daniel Stenberg)
+
+- Bumped version to 1.5.0 for next release and soname bumped to 2 due to ABI
+  and API changes in the progress callback (and possibly more coming up from
+  Steinar)
+
+* September 28 2007 (Steinar H. Gunderson)
+
+- Don't skip a server if it's the only one. (Bugfix from the Google tree.)
+
+- Made the query callbacks receive the number of timeouts that happened during
+  the execution of a query, and updated documentation accordingly. (Patch from
+  the Google tree.)
+
+- Support a few more socket options: ARES_OPT_SOCK_SNDBUF and
+  ARES_OPT_SOCK_RCVBUF
+
+- Always register for TCP events even if there are no outstanding queries, as
+  the other side could always close the connection, which is a valid event
+  which should be responded to.
+
+* September 22 2007 (Daniel Stenberg)
+
+- Steinar H. Gunderson fixed: Correctly clear sockets from the fd_set on in
+  several functions (write_tcp_data, read_tcp_data, read_udp_packets) so that
+  if it fails and the socket is closed the following code doesn't try to use
+  the file descriptor.
+
+- Steinar H. Gunderson modified c-ares to now also do to DNS retries even when
+  TCP is used since there are several edge cases where it still makes sense.
+
+- Brad House provided a fix for ares_save_options():
+
+  Apparently I overlooked something with the ares_save_options() where it
+  would try to do a malloc(0) when no options of that type needed to be saved.
+  On most platforms, this was fine because malloc(0) doesn't actually return
+  NULL, but on AIX it does, so ares_save_options would return ARES_ENOMEM.
+
+* July 14 2007 (Daniel Stenberg)
+
+- Vlad Dinulescu fixed two outstanding valgrind reports:
+
+  1. In ares_query.c , in find_query_by_id we compare q->qid (which is a short
+  int variable) with qid, which is declared as an int variable.  Moreover,
+  DNS_HEADER_SET_QID is used to set the value of qid, but DNS_HEADER_SET_QID
+  sets only the first two bytes of qid. I think that qid should be declared as
+  "unsigned short" in this function.
+
+  2. The same problem occurs in ares_process.c, process_answer() .  query->qid
+  (an unsigned short integer variable) is compared with id, which is an
+  integer variable. Moreover, id is initialized from DNS_HEADER_QID which sets
+  only the first two bytes of id. I think that the id variable should be
+  declared as "unsigned short" in this function.
+
+  Even after declaring these variables as "unsigned short", the valgrind
+  errors are still there. Which brings us to the third problem.
+
+  3. The third problem is that Valgrind assumes that query->qid is not
+  initialised correctly. And it does that because query->qid is set from
+  DNS_HEADER_QID(qbuf); Valgrind says that qbuf has unitialised bytes. And
+  qbuf has uninitialised bytes because of channel->next_id . And next_id is
+  set by ares_init.c:ares__generate_new_id() . I found that putting short r=0
+  in this function (instead of short r) makes all Valgrind warnings go away.
+  I have studied ares__rc4() too, and this is the offending line:
+
+        buffer_ptr[counter] ^= state[xorIndex];   (ares_query.c:62)
+
+  This is what triggers Valgrind.. buffer_ptr is unitialised in this function,
+  and by applying ^= on it, it remains unitialised.
+
+Version 1.4.0 (June 8, 2007)
+
+* June 4 2007 (Daniel Stenberg)
+
+- James Bursa reported a major memory problem when resolving multi-IP names
+  and I found and fixed the problem. It was added by Ashish Sharma's patch
+  two days ago.
+
+  When I then tried to verify multiple entries in /etc/hosts after my fix, I
+  got another segfault and decided this code was not ripe for inclusion and I
+  reverted the patch.
+
+* June 2 2007
+
+- Brad Spencer found and fixed three flaws in the code, found with the new
+  gcc 4.2.0 warning: -Waddress
+
+- Brad House fixed VS2005 compiler warnings due to time_t being 64bit.
+  He also made recent Microsoft compilers use _strdup() instead of strdup().
+
+- Brad House's man pages for ares_save_options() and ares_destroy_options()
+  were added.
+
+- Ashish Sharma provided a patch for supporting multiple entries in the
+  /etc/hosts file. Patch edited for coding style and functionality by me
+  (Daniel).
+
+* May 30 2007
+
+- Shmulik Regev brought cryptographically secure transaction IDs:
+
+  The c-ares library implementation uses a DNS "Transaction ID" field that is
+  seeded with a pseudo random number (based on gettimeofday) which is
+  incremented (++) between consecutive calls and is therefore rather
+  predictable. In general, predictability of DNS Transaction ID is a well
+  known security problem (e.g.
+  http://bak.spc.org/dms/archive/dns_id_attack.txt) and makes a c-ares based
+  implementation vulnerable to DNS poisoning. Credit goes to Amit Klein
+  (Trusteer) for identifying this problem.
+
+  The patch I wrote changes the implementation to use a more secure way of
+  generating unique IDs. It starts by obtaining a key with reasonable entropy
+  which is used with an RC4 stream to generate the cryptographically secure
+  transaction IDs.
+
+  Note that the key generation code (in ares_init:randomize_key) has two
+  versions, the Windows specific one uses a cryptographically safe function
+  provided (but undocumented :) by the operating system (described at
+  http://blogs.msdn.com/michael_howard/archive/2005/01/14/353379.aspx).  The
+  default implementation is a bit naive and uses the standard 'rand'
+  function. Surely a better way to generate random keys exists for other
+  platforms.
+
+  The patch can be tested by using the adig utility and using the '-s' option.
+
+- Brad House added ares_save_options() and ares_destroy_options() that can be
+  used to keep options for later re-usal when ares_init_options() is used.
+
+  Problem: Calling ares_init() for each lookup can be unnecessarily resource
+         intensive.  On windows, it must LoadLibrary() or search the registry
+         on each call to ares_init().  On unix, it must read and parse
+         multiple files to obtain the necessary configuration information.  In
+         a single-threaded environment, it would make sense to only
+         ares_init() once, but in a heavily multi-threaded environment, it is
+         undesirable to ares_init() and ares_destroy() for each thread created
+         and track that.
+
+  Solution: Create ares_save_options() and ares_destroy_options() functions to
+         retrieve and free options obtained from an initialized channel.  The
+         options populated can be used to pass back into ares_init_options(),
+         it should populate all needed fields and not retrieve any information
+         from the system.  Probably wise to destroy the cache every minute or
+         so to prevent the data from becoming stale.
+
+- Daniel S added ares_process_fd() to allow applications to ask for processing
+  on specific sockets and thus avoiding select() and associated
+  functions/macros.  This function will be used by upcoming libcurl releases
+  for this very reason. It also made me export the ares_socket_t type in the
+  public ares.h header file, since ares_process_fd() uses that type for two of
+  the arguments.
+
+* May 25 2007
+
+- Ravi Pratap fixed a flaw in the init_by_resolv_conf() function for windows
+  that could cause it to return a bad return code.
+
+* April 16 2007
+
+- Yang Tse: Provide ares_getopt() command-line parser function as a source
+  code helper function, not belonging to the actual c-ares library.
+
+* February 19 2007
+
+- Vlad Dinulescu added ares_parse_ns_reply().
+
+* February 13 2007
+
+- Yang Tse: Fix failure to get the search sequence of /etc/hosts and
+  DNS from /etc/nsswitch.conf, /etc/host.conf or /etc/svc.conf when
+  /etc/resolv.conf did not exist or was unable to read it.
+
+* November 22 2006
+
+- Install ares_dns.h too
+
+- Michael Wallner fixed this problem: When I set domains in the options
+  struct, and there are domain/search entries in /etc/resolv.conf, the domains
+  of the options struct will be overridden.
+
+* November 6 2006
+
+- Yang Tse removed a couple of potential zero size memory allocations.
+
+- Andreas Rieke fixed the line endings in the areslib.dsp file that I (Daniel)
+  broke in the 1.3.2 release. We should switch to a system where that file is
+  auto-generated. We could rip some code for that from curl...
+
+Version 1.3.2 (November 3, 2006)
+
+* October 12 2006
+
+- Prevent ares_getsock() to overflow if more than 16 sockets are used.
+
+* September 11 2006
+
+- Guilherme Balena Versiani: I noted a strange BUG in Win32 port
+  (ares_init.c/get_iphlpapi_dns_info() function): when I disable the network
+  by hand or disconnect the network cable in Windows 2000 or Windows XP, my
+  application gets 127.0.0.1 as the only name server. The problem comes from
+  'GetNetworkParams' function, that returns the empty string "" as the only
+  name server in that case. Moreover, the Windows implementation of
+  inet_addr() returns INADDR_LOOPBACK instead of INADDR_NONE.
+
+* August 29 2006
+
+- Brad Spencer did
+
+  o made ares_version.h use extern "C" for c++ compilers
+  o fixed compiler warnings in ares_getnameinfo.c
+  o fixed a buffer position init for TCP reads
+
+* August 3 2006
+
+- Ravi Pratap fixed ares_getsock() to actually return the proper bitmap and
+  not always zero!
+
+Version 1.3.1 (June 24, 2006)
+
+* July 23, 2006
+
+- Gisle Vanem added getopt() to the ahost program. Currently accepts
+  only [-t {a|aaaa}] to specify address family in ares_gethostbyname().
+
+* June 19, 2006
+
+- (wahern) Removed "big endian" DNS section and RR data integer parser
+  macros from ares_dns.h, which break c-ares on my Sparc64. Bit-wise
+  operations in C operate on logical values. And in any event the octets are
+  already in big-endian (aka network) byte order so they're being reversed
+  (thus the source of the breakage).
+
+* June 18, 2006
+
+- William Ahern handles EAGAIN/EWOULDBLOCK errors in most of the I/O calls
+  from area_process.c.
+
+  TODO: Handle one last EAGAIN for a UDP socket send(2) in
+  ares__send_query().
+
+* May 10, 2006
+
+- Bram Matthys brought my attention to a libtool peculiarity where detecting
+  things such as C++ compiler actually is a bad thing and since we don't need
+  that detection I added a work-around, much inspired by a previous patch by
+  Paolo Bonzini. This also shortens the configure script quite a lot.
+
+* May 3, 2006
+
+- Nick Mathewson added the ARES_OPT_SOCK_STATE_CB option that when set makes
+  c-ares call a callback on socket state changes. A better way than the
+  ares_getsock() to get full control over the socket state.
+
+* January 9, 2006
+
+- Alexander Lazic improved the getservbyport_r() configure check.
+
+* January 6, 2006
+
+- Alexander Lazic pointed out that the buildconf should use the ACLOCAL_FLAGS
+  variable for easier controlling what it does and how it runs.
+
+* January 5, 2006
+
+- James Bursa fixed c-ares to find the hosts file on RISC OS, and made it
+  build with newer gcc versions that no longer defines "riscos".
+
+* December 22
+
+- Daniel Stenberg added ares_getsock() that extracts the set of sockets to
+  wait for action on. Similar to ares_fds() but not restricted to using
+  select() for the waiting.
+
+* November 25
+
+- Yang Tse fixed some send() / recv() compiler warnings
+
+* September 18
+
+- Added constants that will be used by ares_getaddrinfo
+
+- Made ares_getnameinfo use the reentrant getservbyport (getservbyport_r) if it
+  is available to ensure it works properly in a threaded environment.
+
+* September 10
+
+- configure fix for detecting a member in the sockaddr_in6 struct which failed
+  on ipv6-enabled HP-UX 11.00
+
+Version 1.3.0 (August 29, 2005)
+
+* August 21
+
+- Alfredo Tupone provided a fix for the Windows code in get_iphlpapi_dns_info()
+  when getting the DNS server etc.
+
+* June 19
+
+- Added some checks for the addrinfo structure.
+
+* June 2
+
+- William Ahern:
+
+  Make UDP sockets non-blocking. I've confirmed that at least on Linux 2.4 a
+  read event can come back from poll() on a valid SOCK_DGRAM socket but
+  recv(2) will still block. This patch doesn't ignore EAGAIN in
+  read_udp_packets(), though maybe it should. (This patch was edited by Daniel
+  Stenberg and a new configure test was added (imported from curl's configure)
+  to properly detect what non-blocking socket approach to use.)
+
+  I'm not quite sure how this was happening, but I've been seeing PTR queries
+  which seem to return empty responses. At least, they were empty when calling
+  ares_expand_name() on the record. Here's a patch which guarantees to
+  NUL-terminate the expanded name. The old behavior failed to NUL-terminate if
+  len was 0, and this was causing strlen() to run past the end of the buffer
+  after calling ares_expand_name() and getting ARES_SUCCESS as the return
+  value. If q is not greater than *s then it's equal and *s is always
+  allocated with at least one byte.
+
+* May 16
+
+- Added ares_getnameinfo which mimics the getnameinfo API (another feature
+  that could use testing).
+
+* May 14
+
+- Added an inet_ntop function from BIND for systems that do not have it.
+
+* April 9
+
+- Made sortlist support IPv6 (this can probably use some testing).
+
+- Made sortlist support CIDR matching for IPv4.
+
+* April 8
+
+- Added preliminary IPv6 support to ares_gethostbyname. Currently, sortlist
+  does not work with IPv6. Also provided an implementation of bitncmp from
+  BIND for systems that do not supply this function. This will be used to add
+  IPv6 support to sortlist.
+
+- Made ares_gethostbyaddr support IPv6 by specifying AF_INET6 as the family.
+  The function can lookup IPv6 addresses both from files (/etc/hosts) and
+  DNS lookups.
+
+* April 7
+
+- Tupone Alfredo fixed includes of arpa/nameser_compat.h to build fine on Mac
+  OS X.
+
+* April 5
+
+- Dominick Meglio: Provided implementations of inet_net_pton and inet_pton
+  from BIND for systems that do not include these functions.
+
+* March 11, 2005
+
+- Dominick Meglio added ares_parse_aaaa_reply.c and did various
+  adjustments. The first little steps towards IPv6 support!
+
+* November 7
+
+- Fixed the VC project and makefile to use ares_cancel and ares_version
+
+* October 24
+
+- The released ares_version.h from 1.2.1 says 1.2.0 due to a maketgz flaw.
+  This is now fixed.
+
+Version 1.2.1 (October 20, 2004)
+
+* September 29
+
+- Henrik Stoerner fix: got a report that Tru64 Unix (the unix from Digital
+  when they made Alpha's) uses /etc/svc.conf for the purpose fixed below for
+  other OSes. He made c-ares check for and understand it if present.
+
+- Now c-ares will use local host name lookup _before_ DNS resolving by default
+  if nothing else is told.
+
+* September 26
+
+- Henrik Stoerner: found out that c-ares does not look at the /etc/host.conf
+  file to determine the sequence in which to search /etc/hosts and DNS.  So on
+  systems where this order is defined by /etc/host.conf instead of a "lookup"
+  entry in /etc/resolv.conf, c-ares will always default to looking in DNS
+  first, and /etc/hosts second.
+
+  c-ares now looks at
+
+  1) resolv.conf (for the "lookup" line);
+  2) nsswitch.fon (for the "hosts:" line);
+  3) host.conf (for the "order" line).
+
+  First match wins.
+
+- Dominick Meglio patched: C-ares on Windows assumed that the HOSTS file is
+  located in a static location. It assumed
+  C:\Windows\System32\Drivers\Etc. This is a poor assumption to make. In fact,
+  the location of the HOSTS file can be changed via a registry setting.
+
+  There is a key called DatabasePath which specifies the path to the HOSTS
+  file:
+  http://www.microsoft.com/technet/itsolutions/network/deploy/depovg/tcpip2k.mspx
+
+  The patch will make c-ares correctly consult the registry for the location
+  of this file.
+
+* August 29
+
+- Gisle Vanem fixed the MSVC build files.
+
+* August 20
+
+- Gisle Vanem made c-ares build and work with his Watt-32 TCP/IP stack.
+
+* August 13
+
+- Harshal Pradhan made a minor syntax change in ares_init.c to make it build
+  fine with MSVC 7.1
+
+* July 24
+
+- Made the lib get built static only if --enable-debug is used.
+
+- Gisle Vanem fixed:
+
+  Basically in loops like handle_errors(), 'query->next' was assigned a local
+  variable and then query was referenced after the memory was freed by
+  next_server(). I've changed that so next_server() and end_query() returns
+  the next query. So callers should use this ret-value.
+
+  The next problem was that 'server->tcp_buffer_pos' had a random value at
+  entry to 1st recv() (luckily causing Winsock to return ENOBUFS).
+
+  I've also added a ares_writev() for Windows to streamline the code a bit
+  more.
+
+* July 20
+- Fixed a few variable return types for some system calls. Made configure
+  check for ssize_t to make it possible to use that when receiving the send()
+  error code. This is necessary to prevent compiler warnings on some systems.
+
+- Made configure create config.h, and all source files now include setup.h that
+  might include the proper config.h (or a handicrafted alternative).
+
+- Switched to 'ares_socket_t' type for sockets in ares, since Windows don't
+  use 'int' for that.
+
+- automake-ified and libool-ified c-ares. Now it builds libcares as a shared
+  lib on most platforms if wanted. (This bloated the size of the release
+  archive with another 200K!)
+
+- Makefile.am now uses Makefile.inc for the c sources, h headers and man
+  pages, to make it easier for other makefiles to use the exact same set of
+  files.
+
+- Adjusted 'maketgz' to use the new automake magic when building distribution
+  archives.
+
+- Anyone desires HTML and/or PDF versions of the man pages in the release
+  archives?
+
+* July 3
+- Günter Knauf made c-ares build and run on Novell Netware.
+
+* July 1
+- Gisle Vanem provided Makefile.dj to build with djgpp, added a few more djgpp
+  fixes and made ares not use 'errno' to provide further info on Windows.
+
+* June 30
+- Gisle Vanem made it build with djgpp and run fine with the Watt-32 stack.
+
+* June 10
+- Gisle Vanem's init patch for Windows:
+
+  The init_by_resolv_conf() function fetches the DNS-server(s)
+  from a series of registry branches.
+
+  This can be wrong in the case where DHCP has assigned nameservers, but the
+  user has overridden these servers with other prefered settings. Then it's
+  wrong to use the DHCPNAMESERVER setting in registry.
+
+  In the case of no global DHCP-assigned or fixed servers, but DNS server(s)
+  per adapter, one has to query the adapter branches.  But how can c-ares know
+  which adapter is valid for use? AFAICS it can't. There could be one adapter
+  that is down (e.g. a VPN adapter).
+
+  So it's better to leave this to the IP Helper API (iphlapi) available in
+  Win-98/2000 and later. My patch falls-back to the old way if not available.
+
+* June 8
+- James Bursa fixed an init issue for RISC OS.
+
+* May 11
+- Nico Stappenbelt reported that when processing domain and search lines in
+  the resolv.conf file, the first entry encountered is processed and used as
+  the search list. According to the manual pages for both Linux, Solaris and
+  Tru64, the last entry of either a domain or a search field is used.
+
+  This is now adjusted in the code
+
+Version 1.2.0 (April 13, 2004)
+
+* April 2, 2004
+- Updated various man pages to look nicer when converted to HTML on the web
+  site.
+
+* April 1, 2004
+- Dirk Manske provided a new function that is now named ares_cancel(). It is
+  used to cancel/cleanup a resolve/request made using ares functions on the
+  given ares channel. It does not destroy/kill the ares channel itself.
+
+- Dominick Meglio cleaned up the formatting in several man pages.
+
+* March 30, 2004
+- Dominick Meglio's new ares_expand_string. A helper function when decoding
+  incoming DNS packages.
+
+- Daniel Stenberg modified the Makefile.in to use a for loop for the man page
+  installation to improve overview and make it easier to add man pages.
+
+Version 1.1.0 (March 11, 2004)
+
+* March 9, 2004
+- Gisle Vanem improved build on Windows.
+
+* February 25, 2004
+- Dan Fandrich found a flaw in the Feb 22 fix.
+
+- Added better configure --enable-debug logic (taken from the curl configure
+  script). Added acinclude.m4 to the tarball.
+
+* February 23, 2004
+- Removed ares_free_errmem(), the function, the file and the man page. It was
+  not used and it did nothing.
+
+- Fixed a lot of code that wasn't "64bit clean" and thus caused a lot of
+  compiler warnings on picky compilers.
+
+* February 22, 2004
+- Dominick Meglio made ares init support multiple name servers in the
+  NameServer key on Windows.
+
+* February 16, 2004
+- Modified ares_private.h to include libcurl's memory debug header if
+  CURLDEBUG is set. This makes all the ares-functions supervised properly by
+  the curl test suite. This also forced me to add inclusion of the
+  ares_private.h header in a few more files that are using some kind of
+  memory-related resources.
+
+- Made the makefile only build ahost and adig if 'make demos' is used.
+
+* February 10, 2004
+- Dirk Manske made ares_version.h installed with 'make install'
+
+* February 4, 2004
+- ares_free_errmem() is subject for removal, it is simply present for future
+  purposes, and since we removed the extra parameter in strerror() it won't
+  be used by c-ares!
+- configure --enable-debug now enables picky compiler options if gcc is used
+- fixed several compiler warnings --enable-debug showed and Joerg Mueller-Tolk
+  reported
+
+Version 1.0.0 (February 3, 2004)
+
+* February 3, 2004
+- now we produce the libcares.a library instead of the previous libares.a
+  since we are no longer compatible
+
+* February 2, 2004
+
+- ares_strerror() has one argument less. This is the first official
+  modification of the existing provided ares API.
+
+* January 29, 2004
+
+- Dirk Manske fixed how the socket is set non-blocking.
+
+* January 4, 2004
+
+- Dominick Meglio made the private gettimeofday() become ares_gettimeofday()
+  instead in order to not pollute the name space and risk colliding with
+  other libraries' versions of this function.
+
+* October 24, 2003. Daniel Stenberg
+
+  Added ares_version().
+
+Version 1.0-pre1 (8 October 2003)
+
+- James Bursa made it run on RISC OS
+
+- Dominick Meglio made it run fine on NT4
+
+- Duncan Wilcox made it work fine on Mac OS X
+
+- Daniel Stenberg adjusted the windows port
+
+- liren at vivisimo.com made the initial windows port
+
+* Imported the sources from ares 1.1.1

+                                How To Compile
+```
+
+Installing Binary Packages
+==========================
+
+Lots of people download binary distributions of c-ares. This document
+does not describe how to install c-ares using such a binary package.
+This document describes how to compile, build and install c-ares from
+source code.
+
+Building from Git
+=================
+
+If you get your code off a Git repository rather than an official
+release tarball, see the [GIT-INFO](GIT-INFO) file in the root directory
+for specific instructions on how to proceed.
+
+In particular, if not using CMake you will need to run `./buildconf` (Unix) or
+`buildconf.bat` (Windows) to generate build files, and for the former
+you will need a local installation of Autotools.  If using CMake the steps are
+the same for both Git and official release tarballs.
+
+AutoTools Build
+===============
+
+### General Information, works on most Unix Platforms (Linux, FreeBSD, etc)
+
+A normal Unix installation is made in three or four steps (after you've
+unpacked the source archive):
+
+    ./configure
+    make
+    make install
+
+You probably need to be root when doing the last command.
+
+If you have checked out the sources from the git repository, read the
+[GIT-INFO](GIT_INFO) on how to proceed.
+
+Get a full listing of all available configure options by invoking it like:
+
+    ./configure --help
+
+If you want to install c-ares in a different file hierarchy than /usr/local,
+you need to specify that already when running configure:
+
+    ./configure --prefix=/path/to/c-ares/tree
+
+If you happen to have write permission in that directory, you can do `make
+install` without being root. An example of this would be to make a local
+install in your own home directory:
+
+    ./configure --prefix=$HOME
+    make
+    make install
+
+### More Options
+
+To force configure to use the standard cc compiler if both cc and gcc are
+present, run configure like
+
+    CC=cc ./configure
+    # or
+    env CC=cc ./configure
+
+To force a static library compile, disable the shared library creation
+by running configure like:
+
+    ./configure --disable-shared
+
+If you're a c-ares developer and use gcc, you might want to enable more
+debug options with the `--enable-debug` option.
+
+### Special Cases
+
+Some versions of uClibc require configuring with `CPPFLAGS=-D_GNU_SOURCE=1`
+to get correct large file support.
+
+The Open Watcom C compiler on Linux requires configuring with the variables:
+
+    ./configure CC=owcc AR="$WATCOM/binl/wlib" AR_FLAGS=-q \
+        RANLIB=/bin/true STRIP="$WATCOM/binl/wstrip" CFLAGS=-Wextra
+
+
+### CROSS COMPILE
+
+(This section was graciously brought to us by Jim Duey, with additions by
+Dan Fandrich)
+
+Download and unpack the c-ares package.
+
+`cd` to the new directory. (e.g. `cd c-ares-1.7.6`)
+
+Set environment variables to point to the cross-compile toolchain and call
+configure with any options you need.  Be sure and specify the `--host` and
+`--build` parameters at configuration time.  The following script is an
+example of cross-compiling for the IBM 405GP PowerPC processor using the
+toolchain from MonteVista for Hardhat Linux.
+
+```sh
+#! /bin/sh
+
+export PATH=$PATH:/opt/hardhat/devkit/ppc/405/bin
+export CPPFLAGS="-I/opt/hardhat/devkit/ppc/405/target/usr/include"
+export AR=ppc_405-ar
+export AS=ppc_405-as
+export LD=ppc_405-ld
+export RANLIB=ppc_405-ranlib
+export CC=ppc_405-gcc
+export NM=ppc_405-nm
+
+./configure --target=powerpc-hardhat-linux \
+     --host=powerpc-hardhat-linux \
+     --build=i586-pc-linux-gnu \
+     --prefix=/opt/hardhat/devkit/ppc/405/target/usr/local \
+     --exec-prefix=/usr/local
+```
+
+You may also need to provide a parameter like `--with-random=/dev/urandom`
+to configure as it cannot detect the presence of a random number
+generating device for a target system.  The `--prefix` parameter
+specifies where c-ares will be installed.  If `configure` completes
+successfully, do `make` and `make install` as usual.
+
+In some cases, you may be able to simplify the above commands to as
+little as:
+
+    ./configure --host=ARCH-OS
+
+
+### Cygwin (Windows)
+
+Almost identical to the unix installation. Run the configure script in the
+c-ares root with `sh configure`. Make sure you have the sh executable in
+`/bin/` or you'll see the configure fail toward the end.
+
+Run `make`
+
+
+### QNX
+
+(This section was graciously brought to us by David Bentham)
+
+As QNX is targeted for resource constrained environments, the QNX headers
+set conservative limits. This includes the `FD_SETSIZE` macro, set by default
+to 32. Socket descriptors returned within the c-ares library may exceed this,
+resulting in memory faults/SIGSEGV crashes when passed into `select(..)`
+calls using `fd_set` macros.
+
+A good all-round solution to this is to override the default when building
+c-ares, by overriding `CFLAGS` during configure, example:
+
+    # configure CFLAGS='-DFD_SETSIZE=64 -g -O2'
+
+
+### RISC OS
+
+The library can be cross-compiled using gccsdk as follows:
+
+    CC=riscos-gcc AR=riscos-ar RANLIB='riscos-ar -s' ./configure \
+         --host=arm-riscos-aof --without-random --disable-shared
+    make
+
+where `riscos-gcc` and `riscos-ar` are links to the gccsdk tools.
+You can then link your program with `c-ares/lib/.libs/libcares.a`.
+
+
+### Android
+
+Method using a configure cross-compile (tested with Android NDK r7b):
+
+  - prepare the toolchain of the Android NDK for standalone use; this can
+    be done by invoking the script:
+
+        ./tools/make-standalone-toolchain.sh
+
+    which creates a usual cross-compile toolchain. Lets assume that you put
+    this toolchain below `/opt` then invoke configure with something
+    like:
+
+    ```
+        export PATH=/opt/arm-linux-androideabi-4.4.3/bin:$PATH
+       ./configure --host=arm-linux-androideabi [more configure options]
+        make
+    ```
+  - if you want to compile directly from our GIT repo you might run into
+    this issue with older automake stuff:
+
+    ```
+        checking host system type...
+        Invalid configuration `arm-linux-androideabi':
+        system `androideabi' not recognized
+        configure: error: /bin/sh ./config.sub arm-linux-androideabi failed
+    ```
+    this issue can be fixed with using more recent versions of `config.sub`
+    and `config.guess` which can be obtained here:
+    http://git.savannah.gnu.org/gitweb/?p=config.git;a=tree
+    you need to replace your system-own versions which usually can be
+    found in your automake folder:
+    `find /usr -name config.sub`
+
+
+CMake builds
+============
+
+Current releases of c-ares introduce a CMake v3+ build system that has been
+tested on most platforms including Windows, Linux, FreeBSD, MacOS, AIX and
+Solaris.
+
+In the most basic form, building with CMake might look like:
+
+```sh
+cd /path/to/cmake/source
+mkdir build
+cd build
+cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=/usr/local/cares ..
+make
+sudo make install
+```
+
+Options
+-------
+
+Options to CMake are passed on the command line using "-D${OPTION}=${VALUE}".
+The values defined are all boolean and take values like On, Off, True, False.
+
+* CARES_STATIC - Build the static library (off by default)
+* CARES_SHARED - Build the shared library (on by default)
+* CARES_INSTALL - Hook in installation, useful to disable if chain building
+* CARES_STATIC_PIC - Build the static library as position-independent (off by
+   default)
+
+
+Ninja
+-----
+
+Ninja is the next-generation build system meant for generators like CMake that
+heavily parallize builds.  Its use is very similar to the normal build:
+
+```sh
+cd /path/to/cmake/source
+mkdir build
+cd build
+cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=/usr/local/cares -G "Ninja" ..
+ninja
+sudo ninja install
+```
+
+Windows MSVC Command Line
+-------------------------
+
+```
+cd \path\to\cmake\source
+mkdir build
+cd build
+cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=C:\cares -G "NMake Makefiles" ..
+nmake
+nmake install
+```
+
+Windows MinGW-w64 Command Line via MSYS
+---------------------------------------
+```
+cd \path\to\cmake\source
+mkdir build
+cd build
+cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=C:\cares -G "MSYS Makefiles" ..
+make
+make install
+```
+
+
+Platform-specific build systems
+===============================
+
+Win32
+-----
+
+### Building Windows DLLs and C run-time (CRT) linkage issues
+
+As a general rule, building a DLL with static CRT linkage is highly
+discouraged, and intermixing CRTs in the same app is something to
+avoid at any cost.
+
+Reading and comprehension of Microsoft Knowledge Base articles
+KB94248 and KB140584 is a must for any Windows developer. Especially
+important is full understanding if you are not going to follow the
+advice given above.
+
+ - [KB94248](http://support.microsoft.com/kb/94248/en-us) - How To Use the C Run-Time
+
+ - [KB140584](http://support.microsoft.com/kb/140584/en-us) - How to link with the correct C Run-Time (CRT) library
+
+ - [KB190799](http://msdn.microsoft.com/en-us/library/ms235460) - Potential Errors Passing CRT Objects Across DLL Boundaries
+
+If your app is misbehaving in some strange way, or it is suffering
+from memory corruption, before asking for further help, please try
+first to rebuild every single library your app uses as well as your
+app using the debug multithreaded dynamic C runtime.
+
+
+### MingW32
+
+Make sure that MinGW32's bin dir is in the search path, for example:
+
+    set PATH=c:\mingw32\bin;%PATH%
+
+then run 'make -f Makefile.m32' in the root dir.
+
+
+### MSVC 6 caveats
+
+If you use MSVC 6 it is required that you use the February 2003 edition PSDK:
+http://www.microsoft.com/msdownload/platformsdk/sdkupdate/psdk-full.htm
+
+
+### MSVC from command line
+
+Run the `vcvars32.bat` file to get a proper environment. The
+`vcvars32.bat` file is part of the Microsoft development environment and
+you may find it in `C:\Program Files\Microsoft Visual Studio\vc98\bin`
+provided that you installed Visual C/C++ 6 in the default directory.
+
+Further details in [README.msvc](README.msvc)
+
+
+### Important static c-ares usage note
+
+When building an application that uses the static c-ares library, you must
+add `-DCARES_STATICLIB` to your `CFLAGS`.  Otherwise the linker will look for
+dynamic import symbols.
+
+
+IBM OS/2
+--------
+
+Building under OS/2 is not much different from building under unix.
+You need:
+
+  - emx 0.9d
+  - GNU make
+  - GNU patch
+  - ksh
+  - GNU bison
+  - GNU file utilities
+  - GNU sed
+  - autoconf 2.13
+
+If during the linking you get an error about `_errno` being an undefined
+symbol referenced from the text segment, you need to add `-D__ST_MT_ERRNO__`
+in your definitions.
+
+If you're getting huge binaries, probably your makefiles have the `-g` in
+`CFLAGS`.
+
+
+NetWare
+-------
+
+To compile `libcares.a` / `libcares.lib` you need:
+
+ - either any gcc / nlmconv, or CodeWarrior 7 PDK 4 or later.
+ - gnu make and awk running on the platform you compile on;
+   native Win32 versions can be downloaded from:
+   http://www.gknw.net/development/prgtools/
+ - recent Novell LibC SDK available from:
+   http://developer.novell.com/ndk/libc.htm
+ - or recent Novell CLib SDK available from:
+   http://developer.novell.com/ndk/clib.htm
+
+Set a search path to your compiler, linker and tools; on Linux make
+sure that the var `OSTYPE` contains the string 'linux'; set the var
+`NDKBASE` to point to the base of your Novell NDK; and then type
+`make -f Makefile.netware` from the top source directory;
+
+

+Major changes since:

+
+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.

+c-ares
+======
+
+This package is based on ares 1.1.1 (written by Greg Hudson). Daniel Stenberg
+decided to fork and release a separate project since the original ares author
+didn't want the improvements that were vital for our use of it.
+
+This package is dubbed 'c-ares' since Daniel wanted this for use within the
+curl project (hence the letter C) and it makes a nice pun. c-ares is not API
+compatible with ares: a new name makes that more obvious to the public.
+
+The original libares was distributed at
+ftp://athena-dist.mit.edu:pub/ATHENA/ares (which seems to not be alive
+anymore).  A local copy of the original ares package is kept here:
+https://c-ares.haxx.se/download/ares-1.1.1.tar.gz

+This is c-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.
+
+The full source code is available in the ['c-ares' release archives](https://c-ares.haxx.se/download/),
+and in a git repository: http://github.com/c-ares/c-ares.  See the
+[INSTALL.md](INSTALL.md) file for build information.
+
+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:
+        https://c-ares.haxx.se/
+
+
+Notes for c-ares hackers
+------------------------
+
+* 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 git 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 to compile 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** responsibility to provide this
+  file. No one at the c-ares project can know how you have built the library.
+
+* File `ares_build.h` includes platform and configuration dependent info,
+  and must not be modified by anyone. Configure script generates it for you.
+
+* We cannot assume anything else but very basic compiler features being
+  present. While c-ares requires an ANSI C compiler to build, some of the
+  earlier ANSI compilers clearly can't deal with some preprocessor operators.
+
+* Newlines must remain unix-style for older compilers' sake.
+
+* Comments must be written in the old-style /* unnested C-fashion */
+
+* Try to keep line lengths below 80 columns.

+
+                How to build c-ares using MSVC or Visual Studio
+               =================================================
+
+
+
+  How to build using MSVC from the command line
+  ---------------------------------------------
+
+  Open a command prompt window and ensure that the environment is properly
+  set up in order to use MSVC or Visual Studio compiler tools.
+
+  Change to c-ares source folder where Makefile.msvc file is located and run:
+
+  > nmake -f Makefile.msvc
+
+  This will build all c-ares libraries as well as three sample programs.
+
+  Once the above command has finished a new folder named MSVCXX will exist
+  below the folder where makefile.msvc is found. The name of the folder
+  depends on the MSVC compiler version being used to build c-ares.
+
+  Below the MSVCXX folder there will exist four folders named 'cares',
+  'ahost', 'acountry', and 'adig'. The 'cares' folder is the one that
+  holds the c-ares libraries you have just generated, the other three
+  hold sample programs that use the libraries.
+
+  The above command builds four versions of the c-ares library, dynamic
+  and static versions and each one in release and debug flavours. Each
+  of these is found in folders named dll-release, dll-debug, lib-release,
+  and lib-debug, which hang from the 'cares' folder mentioned above. Each
+  sample program also has folders with the same names to reflect which
+  library version it is using.
+
+
+  How to install using MSVC from the command line
+  -----------------------------------------------
+
+  In order to allow easy usage of c-ares libraries it may be convenient to
+  install c-ares libraries and header files to a common subdirectory tree.
+
+  Once that c-ares libraries have been built using procedure described above,
+  use same command prompt window to define environment variable INSTALL_DIR
+  to designate the top subdirectory where installation of c-ares libraries and
+  header files will be done.
+
+  > set INSTALL_DIR=c:\c-ares
+
+  Afterwards, run following command to actually perform the installation:
+
+  > nmake -f Makefile.msvc install
+
+  Installation procedure will copy c-ares libraries to subdirectory 'lib' and
+  c-ares header files to subdirectory 'include' below the INSTALL_DIR subdir.
+
+  When environment variable INSTALL_DIR is not defined, installation is done
+  to c-ares source folder where Makefile.msvc file is located.
+
+
+
+  Relationship between c-ares library file names and versions
+  -----------------------------------------------------------
+
+  c-ares static release library version files:
+
+      libcares.lib -> static release library
+
+  c-ares static debug library version files:
+
+      libcaresd.lib -> static debug library
+
+  c-ares dynamic release library version files:
+
+      cares.dll -> dynamic release library
+      cares.lib -> import library for the dynamic release library
+      cares.exp -> export file for the dynamic release library
+
+  c-ares dynamic debug library version files:
+
+      caresd.dll -> dynamic debug library
+      caresd.lib -> import library for the dynamic debug library
+      caresd.exp -> export file for the dynamic debug library
+      caresd.pdb -> debug symbol file for the dynamic debug library
+
+
+  How to use c-ares static libraries
+  ----------------------------------
+
+  When using the c-ares static library in your program, you will have to
+  define preprocessor symbol CARES_STATICLIB while building your program,
+  otherwise you will get errors at linkage stage.
+
+
+Have Fun!

+c-ares version 1.17.2
+
+This is a security and bugfix release.  It addresses a few security related
+issues along with various bugfixes mostly related to portability.
+
+Security:
+ o NodeJS passes NULL for addr and 0 for addrlen to ares_parse_ptr_reply() on
+   systems where malloc(0) returns NULL.  This would cause a crash. [8]
+ o When building c-ares with CMake, the RANDOM_FILE would not be set and
+   therefore downgrade to the less secure random number generator [12]
+ o If ares_getaddrinfo() was terminated by an ares_destroy(), it would cause
+   a crash [13]
+ o Crash in sortaddrinfo() if the list size equals 0 due to an unexpected
+   DNS response [14]
+ o Expand number of escaped characters in DNS replies as per RFC1035 5.1 to
+   prevent spoofing [16], [17]
+ o Perform validation on hostnames to prevent possible XSS due to applications
+   not performing valiation themselves [18]
+
+Changes:
+ o Use non-blocking /dev/urandom for random data to prevent early startup
+   performance issues [5]
+ o z/OS port [6]
+ o ares_malloc(0) is now defined behavior (returns NULL) rather than
+   system-specific to catch edge cases [7]
+
+Bug fixes:
+ o Fuzz testing files were not distributed with official archives [1]
+ o Building tests should not force building of static libraries except on
+   Windows [2]
+ o Windows builds of the tools would fail if built as static due to a missing
+   CARES_STATICLIB definition [3]
+ o Relative headers must use double quotes to prevent pulling in a system
+   library [4]
+ o Fix OpenBSD building by implementing portability updates for including
+   arpa/nameser.h [9]
+ o Fix building out-of-tree for autotools [10]
+ o Make install on MacOS/iOS with CMake was missing the bundle destination so
+   libraries weren't actually installed [11]
+ o Fix retrieving DNS server configuration on MacOS and iOS if the configuration
+   did not include search domains [15]
+ o ares_parse_a_reply and ares_parse_aaa_reply were erroneously using strdup()
+   instead of ares_strdup() [19]

+c-ares release procedure - how to do a release
+==============================================
+
+in the source code repo
+-----------------------
+
+- edit `RELEASE-NOTES` to be accurate
+
+- edit `configure.ac`'s `CARES_VERSION_INFO`, and `CMakeLists.txt`'s
+  `CARES_LIB_VERSIONINFO` set to the same value to denote the current shared
+  object versioning.
+
+- make sure all relevant changes are committed on the master branch
+
+- tag the git repo in this style: `git tag -a cares-1_14_0` -a annotates the
+  tag and we use underscores instead of dots in the version number.
+
+- run "./maketgz 1.14.0" to build the release tarball. It is important that
+  you run this on a machine with the correct set of autotools etc installed
+  as this is what then will be shipped and used by most users on *nix like
+  systems.
+
+- push the git commits and the new tag
+
+- gpg sign the tarball
+
+- upload the resulting files to https://c-ares.haxx.se/download/
+
+- update `ares_version.h` for the next version
+
+in the c-ares-www repo
+----------------------
+
+- edit `index.t` (version number and date),
+
+- edit `changelog.t` (add the new release in there)
+
+- commit all local changes
+
+- tag the repo with the same tag as used for the source repo
+
+- push the git commits and the new tag
+
+inform
+------
+
+- send an email to the c-ares mailing list. Insert the RELEASE-NOTES into the
+  mail.
+
+celebrate
+---------

+c-ares security
+===============
+
+This document is intended to provide guidance on how security vulnerabilities
+should be handled in the c-ares project.
+
+Publishing Information
+----------------------
+
+All known and public c-ares vulnerabilities will be listed on [the c-ares web
+site](https://c-ares.haxx.se/vulns.html).
+
+Security vulnerabilities should not be entered in the project's public bug
+tracker unless the necessary configuration is in place to limit access to the
+issue to only the reporter and the project's security team.
+
+Vulnerability Handling
+----------------------
+
+The typical process for handling a new security vulnerability is as follows.
+
+No information should be made public about a vulnerability until it is
+formally announced at the end of this process. That means, for example that a
+bug tracker entry must NOT be created to track the issue since that will make
+the issue public and it should not be discussed on the project's public
+mailing list. Also messages associated with any commits should not make any
+reference to the security nature of the commit if done prior to the public
+announcement.
+
+- The person discovering the issue, the reporter, reports the vulnerability
+  privately to `c-ares-security@haxx.se`. That's an email alias that reaches a
+  handful of selected and trusted people.
+
+- Messages that do not relate to the reporting or managing of an undisclosed
+  security vulnerability in c-ares are ignored and no further action is
+  required.
+
+- A person in the security team sends an e-mail to the original reporter to
+  acknowledge the report.
+
+- The security team investigates the report and either rejects it or accepts
+  it.
+
+- If the report is rejected, the team writes to the reporter to explain why.
+
+- If the report is accepted, the team writes to the reporter to let him/her
+  know it is accepted and that they are working on a fix.
+
+- The security team discusses the problem, works out a fix, considers the
+  impact of the problem and suggests a release schedule. This discussion
+  should involve the reporter as much as possible.
+
+- The release of the information should be "as soon as possible" and is most
+  often synced with an upcoming release that contains the fix. If the
+  reporter, or anyone else, thinks the next planned release is too far away
+  then a separate earlier release for security reasons should be considered.
+
+- Write a security advisory draft about the problem that explains what the
+  problem is, its impact, which versions it affects, solutions or
+  workarounds, when the release is out and make sure to credit all
+  contributors properly.
+
+- Request a CVE number from
+  [distros@openwall](http://oss-security.openwall.org/wiki/mailing-lists/distros)
+  when also informing and preparing them for the upcoming public security
+  vulnerability announcement - attach the advisory draft for information. Note
+  that 'distros' won't accept an embargo longer than 19 days.
+
+- Update the "security advisory" with the CVE number.
+
+- The security team commits the fix in a private branch. The commit message
+  should ideally contain the CVE number. This fix is usually also distributed
+  to the 'distros' mailing list to allow them to use the fix prior to the
+  public announcement.
+
+- At the day of the next release, the private branch is merged into the master
+  branch and pushed. Once pushed, the information is accessible to the public
+  and the actual release should follow suit immediately afterwards.
+
+- The project team creates a release that includes the fix.
+
+- The project team announces the release and the vulnerability to the world in
+  the same manner we always announce releases. It gets sent to the c-ares
+  mailing list and the oss-security mailing list.
+
+- The security web page on the web site should get the new vulnerability
+  mentioned.
+
+C-ARES-SECURITY (at haxx dot se)
+--------------------------------
+
+Who is on this list? There are a couple of criteria you must meet, and then we
+might ask you to join the list or you can ask to join it. It really isn't very
+formal. We basically only require that you have a long-term presence in the
+c-ares project and you have shown an understanding for the project and its way
+of working. You must've been around for a good while and you should have no
+plans in vanishing in the near future.
+
+We do not make the list of partipants public mostly because it tends to vary
+somewhat over time and a list somewhere will only risk getting outdated.

+- When built to support IPv6, it needs to also support PF_UNSPEC or similar,

+dnl This flag accepts an argument of the form current[:revision[:age]]. So,
+dnl passing -version-info 3:12:1 sets current to 3, revision to 12, and age to
+dnl 1.
+dnl
+dnl If either revision or age are omitted, they default to 0. Also note that age
+dnl must be less than or equal to the current interface number.
+dnl
+dnl Here are a set of rules to help you update your library version information:
+dnl
+dnl 1.Start with version information of 0:0:0 for each libtool library.
+dnl
+dnl 2.Update the version information only immediately before a public release of
+dnl your software. More frequent updates are unnecessary, and only guarantee
+dnl that the current interface number gets larger faster.
+dnl
+dnl 3.If the library source code has changed at all since the last update, then
+dnl increment revision (c:r+1:a)
+dnl
+dnl 4.If any interfaces have been added, removed, or changed since the last
+dnl update, increment current, and set revision to 0. (c+1:r=0:a)
+dnl
+dnl 5.If any interfaces have been added since the last public release, then
+dnl increment age. (c:r:a+1)
+dnl
+dnl 6.If any interfaces have been removed since the last public release, then
+dnl set age to 0. (c:r:a=0)

+.SH NAME
+ares_cancel \- Cancel a resolve
+.SH SYNOPSIS
+.nf
+#include <ares.h>
+
+void ares_cancel(ares_channel \fIchannel\fP)
+.fi
+.SH DESCRIPTION
+The \fBares_cancel(3)\fP function cancels all lookups/requests made on the the
+name service channel identified by \fIchannel\fP.  \fBares_cancel(3)\fP
+invokes the callbacks for each pending query on the channel, passing a status
+of
+.BR ARES_ECANCELLED .
+These calls give the callbacks a chance to clean up any state which might have
+been stored in their arguments. If such a callback invocation adds a new
+request to the channel, that request will \fInot\fP be cancelled by the
+current invocation of \fBares_cancel(3)\fP.
+.SH SEE ALSO
+.BR ares_init (3)
+.BR ares_destroy (3)
+.SH NOTES
+This function was added in c-ares 1.2.0
+
+c-ares 1.6.0 and earlier pass a status of
+.BR ARES_ETIMEOUT
+instead of
+.BR ARES_ECANCELLED .

+.TH ARES_CREATE_QUERY 3 "17 Aug 2012"
+.SH NAME
+ares_create_query \- Compose a single-question DNS query buffer
+.SH SYNOPSIS
+.nf
+#include <ares.h>
+
+int ares_create_query(const char *\fIname\fP,
+                      int \fIdnsclass\fP,
+                      int \fItype\fP,
+                      unsigned short \fIid\fP,
+                      int \fIrd\fP,
+                      unsigned char **\fIbuf\fP,
+                      int *\fIbuflen\fP,
+                      int \fImax_udp_size\fP)
+.fi
+.SH DESCRIPTION
+The \fIares_create_query(3)\fP function composes a DNS query with a single
+question.  The parameter \fIname\fP 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 \fIdnsclass\fP and \fItype\fP give the class and type of the
+query using the values defined in \fB<arpa/nameser.h>\fP.
+
+The parameter \fIid\fP gives a 16-bit identifier for the query.
+
+The parameter \fIrd\fP 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 \fIbuf\fP, and the length of which will
+be stored in the variable pointed to by \fIbuflen\fP.
+
+It is the caller's responsibility to free this buffer using
+\fIares_free_string(3)\fP when it is no longer needed.  The parameter
+\fImax_udp_size\fP should be nonzero to activate EDNS. Usage of
+\fIares_create_query(3)\fP\ with \fImax_udp_size\fP set to zero is equivalent
+to using \fIares_mkquery(3)\fP.
+.SH RETURN VALUES
+.B ares_create_query
+can return any of the following values:
+.TP 15
+.B ARES_SUCCESS
+Construction of the DNS query succeeded.
+.TP 15
+.B ARES_ENOTFOUND
+The query name
+.I name
+refers to a
+.I .onion
+domain name. See RFC 7686.
+.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 AVAILABILITY
+Added in c-ares 1.10.0

+ares_destroy \- Destroy a resolver channel
+.SH SYNOPSIS
+.nf
+#include <ares.h>
+
+void ares_destroy(ares_channel \fIchannel\fP)

+.SH DESCRIPTION
+The \fBares_destroy(3)\fP function destroys the name service channel
+identified by \fIchannel\fP, freeing all memory and closing all sockets used
+by the channel.
+
+\fBares_destroy(3)\fP invokes the callbacks for each pending query on the
+channel, passing a status of \fIARES_EDESTRUCTION\fP. These calls give the
+callbacks a chance to clean up any state which might have been stored in their
+arguments. A callback must not add new requests to a channel being destroyed.

+.TH ARES_GET_SERVERS 3 "5 March 2010"
+.SH NAME
+ares_get_servers, ares_get_servers_ports \- Retrieve name servers from an initialized ares_channel
+.SH SYNOPSIS
+.nf
+.B #include <ares.h>
+.PP
+.B int ares_get_servers(ares_channel \fIchannel\fP, struct ares_addr_node **\fIservers\fP)
+.B int ares_get_servers_ports(ares_channel \fIchannel\fP, struct ares_addr_port_node **\fIservers\fP)
+.fi
+.SH DESCRIPTION
+The \fBares_get_servers(3)\fP function retrieves name servers configuration
+from the
+channel data identified by
+.IR channel ,
+as a linked list of ares_addr_node structs storing a pointer to the first
+node at the address specified by
+.IR servers .
+
+The \fBares_get_servers_ports(3)\fP function also retrieves any per-server
+port information that may have been previously configured, returning a linked
+list of ares_addr_port structures.
+
+Function caller may traverse the returned name server linked list, or may use
+it directly as suitable input for the \fBares_set_servers(3)\fP /
+\fBares_set_servers_ports(3)\fP functions, but
+shall not shrink or extend the list on its own.
+
+Each node of the name server linked list is stored in memory dynamically
+allocated and managed by c-ares. It is the caller's responsibility to free
+the resulting linked list, using \fBares_free_data(3)\fP , once the caller
+does not need it any longer.
+
+This function is capable of handling IPv4 and IPv6 name server
+addresses simultaneously, rendering \fBares_save_options(3)\fP with
+optmask \fBARES_OPT_SERVERS\fP functionally obsolete except for
+IPv4-only name server usage.
+
+.SH RETURN VALUES
+This function may return any of the following values:
+.TP 15
+.B ARES_SUCCESS
+The name servers configuration was successfully retrieved
+.TP 15
+.B ARES_ENOMEM
+The memory was exhausted
+.TP 15
+.B ARES_ENODATA
+The channel data identified by
+.IR channel
+was invalid.
+.SH SEE ALSO
+.BR ares_set_servers (3),
+.BR ares_init_options (3),
+.BR ares_save_options(3)
+.SH AVAILABILITY
+\fBares_get_servers(3)\fP was added in c-ares 1.7.1;
+\fBares_get_servers_ports(3)\fP was added in c-ares 1.11.0.

+.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.

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

+
+int ares_init(ares_channel *\fIchannelptr\fP)
+.fi
+.SH DESCRIPTION
+The \fBares_init(3)\fP function initializes a communications channel for name
+service lookups.  If it returns successfully, \fBares_init(3)\fP will set the
+variable pointed to by \fIchannelptr\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 \fIares_init_options(3)\fP function is provide to offer more init
+alternatives.
+.SH RETURN VALUES
+\fIares_init(3)\fP 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.
+.SH NOTES
+When initializing from

+.SH DESCRIPTION
+The \fBares_init_options(3)\fP function initializes a communications channel
+for name service lookups.  If it returns successfully,
+\fBares_init_options(3)\fP will set the variable pointed to by
+\fIchannelptr\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 \fIoptmask\fP parameter generally 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_UDP_PORT
+.B unsigned short \fIudp_port\fP;
+.br
+The port to use for queries over UDP, in network byte order.
+The default value is 53 (in network byte order), the standard name
+service port.
+.TP 18
+.B ARES_OPT_TCP_PORT
+.B unsigned short \fItcp_port\fP;
+.br
+The port to use for queries over TCP, in network byte order.
+The default value is 53 (in network byte order), the standard name
+service port.
+.TP 18
+.B ARES_OPT_SERVERS
+.B struct in_addr *\fIservers\fP;
+.br
+.B int \fInservers\fP;
+.br
+The list of IPv4 servers to contact, instead of the servers specified in
+resolv.conf or the local named. In order to allow specification of either
+IPv4 or IPv6 name servers, the
+.BR ares_set_servers(3)
+function must be used instead.
+.TP 18
+.B ARES_OPT_DOMAINS
+.B char **\fIdomains\fP;
+.br
+.B int \fIndomains\fP;
+.br
+The domains to search, instead of the domains specified in resolv.conf
+or the domain derived from the kernel hostname variable.
+.TP 18
+.B ARES_OPT_LOOKUPS
+.B char *\fIlookups\fP;
+.br
+The lookups to perform for host queries.
+.I lookups
+should be set to a string of the characters "b" or "f", where "b"
+indicates a DNS lookup and "f" indicates a lookup in the hosts file.
+.TP 18
+.B ARES_OPT_SOCK_STATE_CB
+.B void (*\fIsock_state_cb\fP)(void *data, ares_socket_t socket_fd, int readable, int writable);
+.br
+.B void *\fIsock_state_cb_data\fP;
+.br
+A callback function to be invoked when a socket changes state.
+.I socket_fd
+will be passed the socket whose state has changed;
+.I readable
+will be set to true if the socket should listen for read events, and
+.I writable
+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.
+.TP 18
+.B ARES_OPT_SORTLIST
+.B struct apattern *\fIsortlist\fP;
+.br
+.B int \fInsort\fP;
+.br
+A list of IP address ranges that specifies the order of preference that
+results from \fIares_gethostbyname\fP should be returned in.  Note that
+this can only be used with a sortlist retrieved via
+\fBares_save_options(3)\fP (because
+.B struct apattern
+is opaque); to set a fresh sort list, use \fBares_set_sortlist(3)\fP.
+.TP 18
+.B ARES_OPT_SOCK_SNDBUF
+.B int \fIsocket_send_buffer_size\fP;
+.br
+The send buffer size to set for the socket.
+.TP 18
+.B ARES_OPT_SOCK_RCVBUF
+.B int \fIsocket_receive_buffer_size\fP;
+.br
+The receive buffer size to set for the socket.
+.TP 18

+.B ARES_FLAG_EDNS
+flag is set.
+.TP 18
+.B ARES_OPT_RESOLVCONF
+.B char *\fIresolvconf_path\fP;
+.br
+The path to use for reading the resolv.conf file. The
+.I resolvconf_path
+should be set to a path string, and will be honoured on *nix like systems. The
+default is
+.B /etc/resolv.conf
+.br
+.PP
+The \fIoptmask\fP parameter also includes options without a corresponding
+field in the
+.B ares_options
+structure, as follows:
+.TP 23
+.B ARES_OPT_ROTATE
+Perform round-robin selection of the nameservers configured for the channel
+for each resolution.
+.TP 23
+.B ARES_OPT_NOROTATE
+Do not perform round-robin nameserver selection; always use the list of
+nameservers in the same order.
+.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.
+.TP 23
+.B ARES_FLAG_EDNS
+Include an EDNS pseudo-resource record (RFC 2671) in generated requests.
+.SH RETURN VALUES
+\fBares_init_options(3)\fP 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.
+.SH NOTES
+When initializing from
+.B /etc/resolv.conf,
+(or, alternatively when specified by the
+.I resolvconf_path
+path location)
+\fBares_init_options(3)\fP reads the \fIdomain\fP and \fIsearch\fP directives

+.TH ARES_LIBRARY_CLEANUP 3 "19 May 2009"
+.SH NAME
+ares_library_cleanup \- c-ares library deinitialization
+.SH SYNOPSIS
+.nf
+#include <ares.h>
+
+void ares_library_cleanup(void)
+.fi
+.SH DESCRIPTION
+.PP
+The
+.B ares_library_cleanup
+function uninitializes the c-ares library, freeing all resources
+previously acquired by \fIares_library_init(3)\fP when the library
+was initialized, provided there was only one single previous call to
+\fIares_library_init(3)\fP. If there was more than one previous call to
+\fIares_library_init(3)\fP, this function uninitializes the c-ares
+library only if it is the call matching the call to
+\fIares_library_init(3)\fP which initialized the library
+(usually the very first call to \fIares_library_init(3)\fP).
+Other calls to \fIares_library_cleanup(3)\fP have no effect other than
+decrementing an internal counter.
+.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 sufficiently often such that the
+library is uninitialised, 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

+.SH NAME
+ares_library_init \- c-ares library initialization
+.SH SYNOPSIS
+.nf
+#include <ares.h>
+
+int ares_library_init(int \fIflags\fP)
+
+int ares_library_init_mem(int \fIflags\fP,
+                          void *(*\fIamalloc\fP)(size_t),
+                          void (*\fIafree\fP)(void *ptr),

+.fi
+.SH DESCRIPTION
+.PP
+The
+.B ares_library_init
+function performs initializations internally required by the c-ares
+library that must take place before any other function provided by
+c-ares can be used in a program.
+.PP
+This function must be called at least once 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 number of
+calls to \fIares_library_cleanup(3)\fP equal to the number of calls to
+this function are performed.
+.PP
+Successive calls to this function do nothing further, 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
+The
+.B ares_library_init_mem
+function allows the caller to provide memory management functions that the
+c-ares library will be use instead of \fImalloc(3)\fP, \fIfree(3)\fP and
+\fIrealloc(3)\fP.
+.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
+On Windows platforms, the library user should ensure that \fIWSAStartup()\fP
+is called before the c-ares library is initialized and used.
+.PP
+Win32/64 application DLLs shall not call \fIares_library_init(3)\fP from the
+DllMain function. Doing so will produce deadlocks and other problems.
+.SH FLAGS
+.TP 5
+.B ARES_LIB_INIT_ALL
+Initialize everything possible. This sets all known bits.
+.TP
+.B ARES_LIB_INIT_WIN32
+Initialize Win32/64 specific libraries.
+.TP
+.B ARES_LIB_INIT_NONE
+Initialize nothing extra. This sets no bit.
+.SH RETURN VALUE
+Upon successful completion, ares_library_init() will return 0.  Otherwise, a
+non-zero error number will be returned to indicate the error. Except for
+\fIares_strerror(3)\fP, you shall not call any other c-ares function upon
+\fIares_library_init(3)\fP failure.
+.SH AVAILABILITY
+This function was first introduced in c-ares version 1.7.0 along with the
+definition of preprocessor symbol \fICARES_HAVE_ARES_LIBRARY_INIT\fP as an
+indication of the availability of this function. Its recursive behavior,
+which requires a matching number of calls to \fIares_library_cleanup()\fP
+in order to deinitialize the library, is present since c-ares version
+1.10.0. Earlier versions would deinitialize the library on the first call
+to \fIares_library_cleanup()\fP.
+.PP
+Since the introduction of this function it is absolutely mandatory to
+call it for any Win32/64 program using c-ares.
+.PP
+Non-Win32/64 systems can still use c-ares version 1.7.0 without calling
+\fIares_library_init(3)\fP due to the fact that \fIcurrently\fP it is nearly
+a do-nothing function on non-Win32/64 platforms at this point.

+.TH ARES_LIBRARY_INIT_ANDROID 3 "13 Sept 2017"
+.SH NAME
+ares_library_init_android \- c-ares library Android initialization
+.SH SYNOPSIS
+.nf
+#include <ares.h>
+
+int ares_library_init_android(jobject \fIconnectivity_manager\fP)
+
+int ares_library_android_initialized();
+
+void ares_library_init_jvm(JavaVM *\fIjvm\fP)
+
+.fi
+.SH DESCRIPTION
+The \fIares_library_init_android(3)\fP function performs initializations
+internally required by the c-ares library when used on Android. This can take
+place anytime after \fIares_library_init(3)\fP. It must take place after
+\fIares_library_init_jvm\fP. ares_library_init_android must be called before
+DNS resolution will work on Android 8 (Oreo) or newer when targetSdkVersion is
+set to 26+.
+
+As of Android 8 (API level 26) getting DNS server information has
+becomei more restrictive and can only be accessed using the
+Connectivity Manager. It is necessary to pass the connectivity
+manager to c-ares via JNI. Also, the ACCESS_NETWORK_STATE permission
+must be present in the Android application.
+
+Android older than 8 do not need to to be initialized as they
+are less restrictive. However, this is a run time not compile time
+limitation. Proper Android initialization should take place regardless
+of the targeted Android version.
+
+Deinitialization will take place though \fIares_library_cleanup(3)\fP.
+
+The \fBares_library_init_jvm\fP function allows the caller to register the JVM
+with c-ares.  It's meant to be called during JNI_OnLoad because you're
+guaranteed to have the JVM in that function. The JVM is required in order to
+use the Connectivty Manager registered using
+\fIares_library_init_android(3)\fP. This must be call before
+\fIares_library_init_android(3)\fP.
+
+The \fBares_library_android_initialized\fP function can be used to check
+whether c-ares has been initialized for use with Android.
+.SH RETURN VALUES
+ARES_SUCCESS will be returned on success otherwise an error code will be
+returned.
+.SH THREAD SAFETY
+.B These init functions are 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
+these might call functions from other libraries that
+are thread unsafe, and could conflict with any other thread that is already
+using these other libraries.
+.SH JNI
+Accessing the Connectivity Manager though Java:
+
+Register the \fIares_library_android_init\fP.
+.nf
+  static JNINativeMethod funcs[] = {
+  { "initialize_native",     "(Landroid/net/ConnectivityManager;)I",
+    (void *)&ares_library_init_android}
+  };
+
+  JNIEXPORT jint JNICALL JNI_OnLoad(JavaVM *vm, void *reserved)
+  {
+    JNIEnv *env = NULL;
+    jclass  cls = NULL;
+    jint    res;
+  
+    if ((*vm)->GetEnv(vm, (void **)&env, JNI_VERSION_1_6) != JNI_OK)
+      return -1;
+  
+    cls = (*env)->FindClass(env, JNIT_CLASS);
+    if (cls == NULL)
+      return -1;
+  
+    res = (*env)->RegisterNatives(env, cls, funcs, sizeof(funcs)/sizeof(funcs[0]));
+    if (res != 0)
+      return -1;
+  
+    ares_library_init_jvm(vm);
+    return JNI_VERSION_1_6;
+  }
+.fi
+Calling the registered function from Java:
+.nf
+  public class MyObject {
+    static {
+      System.loadLibrary("cares");
+    }
+  
+    private static native boolean initialize_native(ConnectivityManager
+      connectivity_manager);
+  
+    public static boolean initialize(Context context) {
+      initialize_native((ConnectivityManager)context.getSystemService(Context.CONNECTIVITY_SERVICE));
+    }
+  }
+.fi
+Initializing the Connectivity Manager in JNI directly using an Android
+Context. It is assumed the JVM has aleady been registered through
+\fIJNI_OnLoad\fP.
+.nf
+  void initialize(jobject android_context)
+  {
+    jclass obj_cls = jni_get_class(env, "android/content/Context");
+    jmethodID obj_mid = jni_get_method_id(env, obj_cls, "getSystemService", "(Ljava/lang/String;)Ljava/lang/Object;");
+    jfieldID fid = (*env)->GetStaticFieldID(env, obj_cls, "CONNECTIVITY_SERVICE", "Ljava/lang/String;");
+    jstring str = (*env)->GetStaticObjectField(env, obj_cls, fid);
+    connectivity_manager = (*env)->CallObjectMethod(env, android_context, obj_mid, str);
+    if (connectivity_manager == NULL)
+      return;
+    ares_library_init_android(connectivity_manager);
+  }
+.fi

+.SH NAME
+ares_mkquery \- Compose a single-question DNS query buffer
+.SH SYNOPSIS
+.nf
+.B #include <ares.h>
+.PP
+.B int ares_mkquery(const char *\fIname\fP, int \fIdnsclass\fP, int \fItype\fP,
+.B	unsigned short \fIid\fP, int \fIrd\fP, unsigned char **\fIbuf\fP,
+.B	int *\fIbuflen\fP)
+.fi
+.SH DESCRIPTION
+Deprecated function. See \fIares_create_query(3)\fP instead!
+
+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.
+
+Usage of \fIares_mkquery(3)\fP is deprecated, whereas the function is
+equivalent to \fIares_create_query(3)\fP with \fBmax_udp_size\fP set to
+0.
+
+.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_ENOTFOUND
+The query name
+.I name
+refers to a
+.I .onion
+domain name. See RFC 7686.
+.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.

+.BR "ares_parse_txt_reply" " (" "ares_parse_txt_reply_ext" ")"
+function parses the response to a query of type TXT into a
+linked list (one element per sub-string) of
+.IR "struct ares_txt_reply" " (" "struct ares_txt_ext" ")"
+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 txt_out .
+It is the caller's responsibility to free the resulting
+.IR txt_out
+structure when it is no longer needed using the function
+.B ares_free_data
+.PP
+The structure 
+.I ares_txt_reply
+contains the following fields:
+.sp
+.in +4n
+.nf
+struct ares_txt_reply {
+  struct ares_txt_reply  *next;
+  unsigned int  length;
+  unsigned char *txt;
+};
+.fi
+.in
+.PP
+The structure
+.I ares_txt_ext
+contains the following fields:
+.sp
+.in +4n
+.nf
+struct ares_txt_ext {
+  struct ares_txt_ext  *next;
+  unsigned int  length;
+  unsigned char *txt;
+  unsigned char record_start;
+};
+.fi
+.in
+.PP
+The
+.I record_start
+field in
+.I struct ares_txt_ext
+is 1 if this structure is a start of a TXT record, and 0 if the structure is a
+continuation of a previous record. The linked list of the
+.I struct ares_txt_ext
+will have at least one item with
+.I record_start
+equal to 1, and may have some items with
+.I record_start
+equal to 0 between them.
+.PP
+These sequences of
+.I struct ares_txt_ext
+(starting from the item with
+.I record_start
+equal to 1, and ending right before the record start item) may be treated as
+either components of a single TXT record or as a multi-parted TXT record,
+depending on particular use case.
+.PP
+.SH RETURN VALUES
+.BR "ares_parse_txt_reply" " (" "ares_parse_txt_reply_ext" ")"
+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
+#include <ares.h>
+
+void ares_process(ares_channel \fIchannel\fP,
+                  fd_set *\fIread_fds\fP,
+                  fd_set *\fIwrite_fds\fP)
+
+void ares_process_fd(ares_channel \fIchannel\fP,
+                     ares_socket_t \fIread_fd\fP,
+                     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 \fBselect(3)\fP
+with a timeout no greater than the timeout given by \fIares_timeout(3)\fP).
+
+The \fBares_process(3)\fP 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 provided to allow users of
+c-ares to void \fIselect(3)\fP in their applications and within c-ares.
+
+To only process possible timeout conditions without a socket event occurring,
+one may pass NULL as the values for both \fIread_fds\fP and \fIwrite_fds\fP for
+\fBares_process(3)\fP, or ARES_SOCKET_BAD for both \fIread_fd\fP and
+\fIwrite_fd\fP for \fBares_process_fd(3)\fP.
+.SH EXAMPLE
+The following code fragment waits for all pending queries on a channel
+to complete:
+
+.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);
+}
+.fi

+.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_ECANCELLED
+The query was cancelled.
+.TP 19
+.B ARES_EDESTRUCTION
+The name service channel
+.I channel
+is being destroyed; the query will not be completed.

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

+.SH DESCRIPTION
+The
+.B ares_send
+function initiates a DNS query on the name service channel identified
+by
+.IR channel .
+The parameters
+.I qbuf
+and
+.I qlen
+give the DNS query, which should already have been formatted according
+to the DNS protocol.  When the query is complete or has failed, the
+ares library will invoke

+Completion or failure of the query may happen immediately, or may
+happen during a later call to
+.BR ares_process (3)
+or
+.BR ares_destroy (3).
+.PP
+The callback argument
+.I arg
+is copied from the
+.B ares_send
+argument
+.IR arg .
+The callback argument
+.I status
+indicates whether the query succeeded and, if not, how it failed.  It
+may have any of the following values:
+.TP 19
+.B ARES_SUCCESS
+The query completed.
+.TP 19
+.B ARES_EBADQUERY
+The query buffer was poorly formed (was not long enough for a DNS
+header or was too long for TCP transmission).
+.TP 19
+.B ARES_ETIMEOUT
+No name servers responded within the timeout period.
+.TP 19
+.B ARES_ECONNREFUSED
+No name servers could be contacted.
+.TP 19
+.B ARES_ENOMEM
+Memory was exhausted.
+.TP 19
+.B ARES_ECANCELLED
+The query was cancelled.
+.TP 19
+.B ARES_EDESTRUCTION
+The name service channel
+.I channel
+is being destroyed; the query will not be completed.
+.PP
+The callback argument
+.I timeouts
+reports how many times a query timed out during the execution of the
+given request.
+.PP
+If the query completed, the callback argument
+.I abuf
+points to a result buffer of length
+.IR alen .
+If the query did not complete,
+.I abuf
+will be NULL and
+.I alen
+will be 0.
+.PP
+Unless the flag
+.B ARES_FLAG_NOCHECKRESP
+was set at channel initialization time,
+.B ares_send
+will normally ignore responses whose questions do not match the
+questions in
+.IR qbuf ,
+as well as responses with reply codes of
+.BR SERVFAIL ,
+.BR NOTIMP ,
+and
+.BR REFUSED .
+Unlike other query functions in the ares library, however,
+.B ares_send
+does not inspect the header of the reply packet to determine the error
+status, so a callback status of
+.B ARES_SUCCESS
+does not reflect as much about the response as for other query
+functions.

+ares_set_servers, ares_set_servers_ports \- Initialize an ares_channel name servers configuration
+.SH SYNOPSIS
+.nf
+.B #include <ares.h>
+.PP
+.B int ares_set_servers(ares_channel \fIchannel\fP, struct ares_addr_node *\fIservers\fP)
+.B int ares_set_servers_ports(ares_channel \fIchannel\fP, struct ares_addr_port_node *\fIservers\fP)
+.fi
+.SH DESCRIPTION
+The \fBares_set_servers(3)\fP function initializes name servers configuration
+for the channel data identified by
+.IR channel ,
+from a
+.IR servers
+pointer to a linked list of ares_addr_node structs holding name servers
+address data.
+.PP
+The name server linked list pointer argument may be the result of a previous
+call to \fBares_get_servers(3)\fP or a linked list of \fBares_addr_node\fP structs
+set up by other means.
+.PP
+The \fBares_set_servers(3)\fP function also allows the specification of UDP and
+TCP ports to be used for communication on a per-server basis.  The provided
+linked list argument may be the result of a previous call to
+\fBares_get_servers_ports(3)\fP or a linked list of \fBares_addr_port_node\fP structs
+set up by other means.
+.PP
+This function replaces any potentially previously configured name servers
+with the ones given in the linked list. So, in order to configure a channel
+with more than one name server all the desired ones must be specified in a
+single list.
+.PP
+The function does not take ownership of the linked list argument.
+The caller is responsible for freeing the linked list when no longer needed.
+.PP
+This function is capable of handling IPv4 and IPv6 name server
+addresses simultaneously, rendering \fBares_init_options(3)\fP with
+optmask \fBARES_OPT_SERVERS\fP functionally obsolete except for
+IPv4-only name server usage.
+
+.SH RETURN VALUES
+.B ares_set_servers(3)
+may return any of the following values:
+.TP 15
+.B ARES_SUCCESS
+The name servers configuration was successfully initialized.
+.TP 15
+.B ARES_ENOMEM

+.SH DESCRIPTION
+.PP
+This function sets a set of callback \fIfunctions\fP in the given ares channel handle.
+These callback functions will be invoked to create/destroy socket objects and perform
+io, instead of the normal system calls. A client application can override normal network
+operation fully through this functionality, and provide its own transport layer.
+.PP
+All callback functions are expected to operate like their system equivalents, and to
+set
+.BR errno(3)
+to an appropriate error code on failure. C-ares also expects all io functions to behave
+asynchronously, i.e. as if the socket object has been set to non-blocking mode. Thus
+read/write calls (for TCP connections) are expected to often generate
+.BR EAGAIN
+or
+.BR EWOULDBLOCK.
+
+.PP
+The \fIuser_data\fP value is provided to each callback function invocation to serve as
+context.
+.PP
+The
+.B ares_socket_functions
+must provide the following callbacks:
+.TP 18
+.B \fIasocket\fP
+.B ares_socket_t(*)(int \fIdomain\fP, int \fItype\fP, int \fIprotocol\fP, void * \fIuser_data\fP)

+.TH ARES_TIMEOUT 3 "25 July 1998"
+.SH NAME
+ares_timeout \- return maximum time to wait
+.SH SYNOPSIS
+.nf
+#include <ares.h>
+
+struct timeval *ares_timeout(ares_channel \fIchannel\fP,
+                             struct timeval *\fImaxtv\fP,
+                             struct timeval *\fItv\fP)
+.fi
+.SH DESCRIPTION
+The \fBares_timeout(3)\fP function determines the maximum time for which the
+caller should wait before invoking \fIares_process(3)\fP to process timeouts.
+The parameter \fImaxtv\fP specifies a existing maximum timeout, or \fBNULL\fP
+if the caller does not wish to apply a maximum timeout.  The parameter
+\fItv\fP must point to a writable buffer of type \fBstruct timeval\fP It is
+valid for \fImaxtv\fP and \fItv\fP to have the same value.
+
+If no queries have timeouts pending sooner than the given maximum timeout,
+\fBares_timeout(3)\fP returns the value of \fImaxtv\fP; otherwise
+\fBares_timeout(3)\fP stores the appropriate timeout value into the buffer
+pointed to by \fItv\fP and returns the value of \fItv\fP.

+.TH ARES_VERSION 3 "29 January 2004"
+.SH NAME
+ares_version \- Get the version number of the library
+.SH SYNOPSIS
+.nf
+#include <ares.h>
+
+const char *ares_version(int *\fIversion\fP)
+.fi
+.SH DESCRIPTION
+The \fBares_version(3)\fP function gets the library version as a string and
+optionally as an integer stored in the \fIversion\fP argument. If you pass a
+NULL, no integer is attempted to be returned.
+
+The integer is built up as 24bit number, with 8 separate bits used for major
+number, minor number and patch number. This makes a version string such as
+1.2.3 will be returned as the hexadecimal number 0x010203 (decimal 66051).

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

+# ===========================================================================

+# ===========================================================================
+#
+# SYNOPSIS
+#
+#   AX_CODE_COVERAGE()
+#
+# DESCRIPTION
+#
+#   Defines CODE_COVERAGE_CFLAGS and CODE_COVERAGE_LDFLAGS which should be
+#   included in the CFLAGS and LIBS/LDFLAGS variables of every build target
+#   (program or library) which should be built with code coverage support.
+#   Also defines CODE_COVERAGE_RULES which should be substituted in your
+#   Makefile; and $enable_code_coverage which can be used in subsequent
+#   configure output. CODE_COVERAGE_ENABLED is defined and substituted, and
+#   corresponds to the value of the --enable-code-coverage option, which
+#   defaults to being disabled.
+#
+#   Test also for gcov program and create GCOV variable that could be
+#   substituted.
+#
+#   Note that all optimisation flags in CFLAGS must be disabled when code
+#   coverage is enabled.
+#
+#   Usage example:
+#
+#   configure.ac:
+#
+#     AX_CODE_COVERAGE
+#
+#   Makefile.am:
+#
+#     @CODE_COVERAGE_RULES@
+#     my_program_LIBS = ... $(CODE_COVERAGE_LDFLAGS) ...
+#     my_program_CFLAGS = ... $(CODE_COVERAGE_CFLAGS) ...
+#
+#   This results in a "check-code-coverage" rule being added to any
+#   Makefile.am which includes "@CODE_COVERAGE_RULES@" (assuming the module
+#   has been configured with --enable-code-coverage). Running `make
+#   check-code-coverage` in that directory will run the module's test suite
+#   (`make check`) and build a code coverage report detailing the code which
+#   was touched, then print the URI for the report.
+#
+#   This code was derived from Makefile.decl in GLib, originally licenced
+#   under LGPLv2.1+.

+# SYNOPSIS
+#
+#   AX_CXX_COMPILE_STDCXX_11([ext|noext],[mandatory|optional])
+#
+# DESCRIPTION
+#
+#   Check for baseline language coverage in the compiler for the C++11
+#   standard; if necessary, add switches to CXXFLAGS to enable support.
+#
+#   The first argument, if specified, indicates whether you insist on an
+#   extended mode (e.g. -std=gnu++11) or a strict conformance mode (e.g.
+#   -std=c++11).  If neither is specified, you get whatever works, with
+#   preference for an extended mode.
+#
+#   The second argument, if specified 'mandatory' or if left unspecified,
+#   indicates that baseline C++11 support is required and that the macro
+#   should error out if no mode with that support is found.  If specified
+#   'optional', then configuration proceeds regardless, after defining
+#   HAVE_CXX11 if and only if a supporting mode is found.

+# SYNOPSIS
+#
+#   AX_PTHREAD([ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]])
+#
+# DESCRIPTION
+#
+#   This macro figures out how to build C programs using POSIX threads. It
+#   sets the PTHREAD_LIBS output variable to the threads library and linker
+#   flags, and the PTHREAD_CFLAGS output variable to any special C compiler
+#   flags that are needed. (The user can also force certain compiler
+#   flags/libs to be tested by setting these environment variables.)
+#
+#   Also sets PTHREAD_CC to any special C compiler that is needed for
+#   multi-threaded programs (defaults to the value of CC otherwise). (This
+#   is necessary on AIX to use the special cc_r compiler alias.)
+#
+#   NOTE: You are assumed to not only compile your program with these flags,
+#   but also link it with them as well. e.g. you should link with
+#   $PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS $LIBS
+#
+#   If you are only building threads programs, you may wish to use these
+#   variables in your default LIBS, CFLAGS, and CC:
+#
+#     LIBS="$PTHREAD_LIBS $LIBS"
+#     CFLAGS="$CFLAGS $PTHREAD_CFLAGS"
+#     CC="$PTHREAD_CC"
+#
+#   In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute constant
+#   has a nonstandard name, defines PTHREAD_CREATE_JOINABLE to that name
+#   (e.g. PTHREAD_CREATE_UNDETACHED on AIX).
+#
+#   Also HAVE_PTHREAD_PRIO_INHERIT is defined if pthread is found and the
+#   PTHREAD_PRIO_INHERIT symbol is defined when compiling with
+#   PTHREAD_CFLAGS.
+#
+#   ACTION-IF-FOUND is a list of shell commands to run if a threads library
+#   is found, and ACTION-IF-NOT-FOUND is a list of commands to run it if it
+#   is not found. If ACTION-IF-FOUND is not specified, the default action
+#   will define HAVE_PTHREAD.
+#
+#   Please let the authors know if this macro fails on any platform, or if
+#   you have any other suggestions or comments. This macro was based on work
+#   by SGJ on autoconf scripts for FFTW (http://www.fftw.org/) (with help
+#   from M. Frigo), as well as ac_pthread and hb_pthread macros posted by
+#   Alejandro Forero Cuervo to the autoconf macro repository. We are also
+#   grateful for the helpful feedback of numerous users.

+dnl separated list argument.
+dnl
+dnl Embedding only takes place when using automake 1.14

+dnl in generated configure script.
+dnl
+dnl distclean and maintainer-clean targets are modified
+dnl to avoid unconditional removal of dependency subdirs
+dnl which triggers distclean and maintainer-clean errors
+dnl when using automake 'subdir-objects' option along
+dnl with per-target objects and source files existing in
+dnl multiple subdirs used for different build targets.
+dnl
+dnl New behavior first removes each dependency tracking
+dnl file independently, and only removes each dependency
+dnl subdir when it finds out that it no longer holds any
+dnl dependency tracking file.
+dnl
+dnl When configure option --disable-dependency-tracking
+dnl is used no amending takes place given that there are

+dnl
+dnl This macro emits shell code which does some
+dnl very basic checks related with the availability
+dnl of some commands and utilities needed to allow
+dnl configure script bootstrapping itself when using
+dnl these to figure out other settings. Also emits
+dnl code that performs PATH_SEPARATOR auto-detection
+dnl and sets its value unless it is already set with
+dnl a non-empty value.
+dnl
+dnl These basic checks are intended to be placed and
+dnl executed as early as possible in the resulting
+dnl configure script, and as such these must be pure
+dnl and portable shell code.
+dnl
+dnl This macro may be used directly, or indirectly
+dnl when using other macros that AC_REQUIRE it such
+dnl as XC_CHECK_PATH_SEPARATOR.
+dnl
+dnl Currently the mechanism used to ensure that this
+dnl macro expands early enough in generated configure
+dnl script is making it override autoconf and libtool
+dnl PATH_SEPARATOR check.

+dnl Strictly speaking the check is done in two steps. The
+dnl first, which does the actual check, takes place in
+dnl XC_CONFIGURE_PREAMBLE macro and happens very early in
+dnl generated configure script. The second one shows and
+dnl logs the result of the check into config.log at a later
+dnl configure stage. Placement of this second stage in

+ * set to the length of the encoded name (not the length of the
+ * expanded name; the goal is to tell the caller how many bytes to
+ * move forward to get past the encoded name).
+ *
+ * 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.
+ *
+ * If the result is expected to be a hostname, then no escaped data is allowed

+ * associated with the interface that the DNS requests themselves will
+ * travel.  This gives us optimal routing and avoids issues where DNS servers
+ * won't respond to requests that don't arrive via some specific subnetwork
+ * (and thus some specific interface).
+ *
+ * This function computes the metric we use to sort.  On the interface
+ * identified by \a luid, it determines the best route to \a dest and combines
+ * that route's metric with \a interfaceMetric to compute a metric for the
+ * destination address on that interface.  This metric can be used as a weight
+ * to sort the DNS server addresses associated with each interface (lower is
+ * better).
+ *
+ * Note that by restricting the route search to the specific interface with

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

+c-ares Unit Test Suite
+======================
+
+
+This directory holds unit tests for the c-ares library.  To build the tests:
+
+ - Build the main c-ares library first, in the directory above this.  To
+   enable tests of internal functions, configure the library build to expose
+   hidden symbols with `./configure --disable-symbol-hiding`.
+ - Generate a `configure` file by running `autoreconf -iv` (which requires
+   a local installation of
+   [autotools](https://www.gnu.org/software/automake/manual/html_node/Autotools-Introduction.html)).
+ - `./configure`
+ - `make`
+ - Run the tests with `./arestest`, or `./arestest -v` for extra debug info.
+
+Points to note:
+
+ - The tests are written in C++11, and so need a C++ compiler that supports
+   this.  To avoid adding this as a requirement for the library, the
+   configuration and build of the tests is independent from the library.
+ - The tests include some live queries, which will fail when run on a machine
+   without internet connectivity.  To skip live tests, run with
+   `./arestest --gtest_filter=-*.Live*`.
+ - The tests include queries of a mock DNS server.  This server listens on port
+   5300 by default, but the port can be changed with the `-p 5300` option to
+   `arestest`.
+
+
+Test Types
+----------
+
+The test suite includes various different types of test.
+
+ - There are live tests (`ares-test-live.cc`), which assume that the
+   current machine has a valid DNS setup and connection to the
+   internet; these tests issue queries for real domains but don't
+   particularly check what gets returned.  The tests will fail on
+   an offline machine.
+ - There are some mock tests (`ares-test-mock.cc`) that set up a fake DNS
+   server and inject its port into the c-ares library configuration.
+   These tests allow specific response messages to be crafted and
+   injected, and so are likely to be used for many more tests in
+   future.
+    - To make this generation/injection easier, the `dns-proto.h`
+      file includes C++ helper classes for building DNS packets.
+ - Other library entrypoints that don't require network activity
+   (e.g. `ares_parse_*_reply`) are tested directly.
+ - A couple of the tests use a helper method of the test fixture to
+   inject memory allocation failures, using a recent change to the
+   c-ares library that allows override of `malloc`/`free`.
+ - There are some tests of the internal entrypoints of the library
+   (`ares-test-internal.c`), but these are only enabled if the library
+   was configured with `--disable-symbol-hiding` and/or
+   `--enable-expose-statics`.
+ - There is also an entrypoint to allow Clang's
+   [libfuzzer](http://llvm.org/docs/LibFuzzer.html) to drive
+   the packet parsing code in `ares_parse_*_reply`, together with a
+   standalone wrapper for it (`./aresfuzz`) to allow use of command
+   line fuzzers (such as [afl-fuzz](http://lcamtuf.coredump.cx/afl/))
+   for further [fuzz testing](#fuzzing).

+-------------------------
+
+To generate code coverage information:
+
+ - Configure both the library and the tests with `./configure
+   --enable-code-coverage` before building. This requires the relevant code
+   coverage tools ([gcov](https://gcc.gnu.org/onlinedocs/gcc/Gcov.html),
+   [lcov](http://ltp.sourceforge.net/coverage/lcov.php)) to be installed locally.
+ - Run the tests with `test/arestest`.
+ - Generate code coverage output with `make code-coverage-capture` in the
+   library directory (i.e. not in `test/`).
+
+
+Fuzzing
+-------
+
+### libFuzzer
+
+To fuzz the packet parsing code with libFuzzer, follow the main
+[libFuzzer instructions](http://llvm.org/docs/LibFuzzer.html):
+
+ - Configure the c-ares library and test suite with a recent Clang and a sanitizer, for example:
+
+   ```console
+   % export CFLAGS="-fsanitize=fuzzer-no-link,address"
+   % export CC=clang
+   % ./configure --disable-shared && make
+   ```
+ - Link each of the fuzzer entrypoints in with `ares-fuzz.cc`:
+
+   ```
+   % clang -I.. -c ares-test-fuzz.c
+   % clang -I.. -c ares-test-fuzz-name.c
+   % clang++ -fsanitize=fuzzer,address ares-test-fuzz.o ../.libs/libcares.a -o ares-libfuzzer
+   % clang++ -fsanitize=fuzzer,address ares-test-fuzz-name.o ../.libs/libcares.a -o ares-libfuzzer-name
+   ```
+ - Run the fuzzer using the starting corpus with:
+
+   ```console
+   % ./ares-libfuzzer fuzzinput/  # OR
+   % ./ares-libfuzzer-name fuzznames/
+   ```
+
+### AFL
+
+To fuzz using AFL, follow the
+[AFL quick start guide](http://lcamtuf.coredump.cx/afl/QuickStartGuide.txt):
+
+ - Download and build AFL.
+ - Configure the c-ares library and test tool to use AFL's compiler wrappers:
+
+   ```console
+   % export CC=$AFLDIR/afl-gcc
+   % ./configure --disable-shared && make
+   % cd test && ./configure && make aresfuzz aresfuzzname
+   ```
+
+ - Run the AFL fuzzer against the starting corpus:
+
+   ```console
+   % mkdir fuzzoutput
+   % $AFLDIR/afl-fuzz -i fuzzinput -o fuzzoutput -- ./aresfuzz  # OR
+   % $AFLDIR/afl-fuzz -i fuzznames -o fuzzoutput -- ./aresfuzzname
+   ```
+
+### AFL Persistent Mode
+
+If a recent version of Clang is available, AFL can use its built-in compiler
+instrumentation; this configuration also allows the use of a (much) faster
+persistent mode, where multiple fuzz inputs are run for each process invocation.
+
+ - Download and build a recent AFL, and run `make` in the `llvm_mode`
+   subdirectory to ensure that `afl-clang-fast` gets built.
+ - Configure the c-ares library and test tool to use AFL's clang wrappers that
+   use compiler instrumentation:
+
+   ```console
+   % export CC=$AFLDIR/afl-clang-fast
+   % ./configure --disable-shared && make
+   % cd test && ./configure && make aresfuzz
+   ```
+
+ - Run the AFL fuzzer (in persistent mode) against the starting corpus:
+
+   ```console
+   % mkdir fuzzoutput
+   % $AFLDIR/afl-fuzz -i fuzzinput -o fuzzoutput -- ./aresfuzz
+   ```
+

+// A few implementation notes:  Like the Linux version, the Windows
+// implementation uses pipes for child-to-parent communication. But due to
+// the specifics of pipes on Windows, some extra steps are required:
+//
+// 1. The parent creates a communication pipe and stores handles to both
+//    ends of it.
+// 2. The parent starts the child and provides it with the information
+//    necessary to acquire the handle to the write end of the pipe.
+// 3. The child acquires the write end of the pipe and signals the parent
+//    using a Windows event.
+// 4. Now the parent can release the write end of the pipe on its side. If
+//    this is done before step 3, the object's reference count goes down to
+//    0 and it is destroyed, preventing the child from acquiring it. The
+//    parent now has to release it, or read operations on the read end of
+//    the pipe will not return when the child terminates.
+// 5. The parent reads child's output through the pipe (outcome code and
+//    any possible error messages) from the pipe, and its stderr and then
+//    determines whether to fail the test.
+//
+// Note: to distinguish Win32 API calls from the local method and function
+// calls, the former are explicitly resolved in the global namespace.

+// FindMaxBipartiteMatching and its helper class.

+// Uses the well-known Ford-Fulkerson max flow method to find a maximum
+// bipartite matching. Flow is considered to be from left to right.
+// There is an implicit source node that is connected to all of the left
+// nodes, and an implicit sink node that is connected to all of the
+// right nodes. All edges have unit capacity.
+//
+// Neither the flow graph nor the residual flow graph are represented
+// explicitly. Instead, they are implied by the information in 'graph' and
+// a vector<int> called 'left_' whose elements are initialized to the
+// value kUnused. This represents the initial state of the algorithm,
+// where the flow graph is empty, and the residual flow graph has the
+// following edges:
+//   - An edge from source to each left_ node
+//   - An edge from each right_ node to sink
+//   - An edge from each left_ node to each right_ node, if the
+//     corresponding edge exists in 'graph'.
+//
+// When the TryAugment() method adds a flow, it sets left_[l] = r for some
+// nodes l and r. This induces the following changes:
+//   - The edges (source, l), (l, r), and (r, sink) are added to the
+//     flow graph.
+//   - The same three edges are removed from the residual flow graph.
+//   - The reverse edges (l, source), (r, l), and (sink, r) are added
+//     to the residual flow graph, which is a directional graph
+//     representing unused flow capacity.
+//
+// When the method augments a flow (moving left_[l] from some r1 to some
+// other r2), this can be thought of as "undoing" the above steps with
+// respect to r1 and "redoing" them with respect to r2.
+//
+// It bears repeating that the flow graph and residual flow graph are
+// never represented explicitly, but can be derived by looking at the
+// information in 'graph' and in left_.
+//
+// As an optimization, there is a second vector<int> called right_ which
+// does not provide any new information. Instead, it enables more
+// efficient queries about edges entering or leaving the right-side nodes
+// of the flow or residual flow graphs. The following invariants are
+// maintained:

+// The ACTION* family of macros can be used in a namespace scope to
+// define custom actions easily.  The syntax:
+//
+//   ACTION(name) { statements; }
+//
+// will define an action with the given name that executes the
+// statements.  The value returned by the statements will be used as
+// the return value of the action.  Inside the statements, you can
+// refer to the K-th (0-based) argument of the mock function by
+// 'argK', and refer to its type by 'argK_type'.  For example:
+//
+//   ACTION(IncrementArg1) {
+//     arg1_type temp = arg1;
+//     return ++(*temp);
+//   }
+//
+// allows you to write
+//
+//   ...WillOnce(IncrementArg1());
+//
+// You can also refer to the entire argument tuple and its type by
+// 'args' and 'args_type', and refer to the mock function type and its
+// return type by 'function_type' and 'return_type'.
+//
+// Note that you don't need to specify the types of the mock function
+// arguments.  However rest assured that your code is still type-safe:
+// you'll get a compiler error if *arg1 doesn't support the ++
+// operator, or if the type of ++(*arg1) isn't compatible with the
+// mock function's return type, for example.
+//
+// Sometimes you'll want to parameterize the action.   For that you can use
+// another macro:
+//
+//   ACTION_P(name, param_name) { statements; }
+//
+// For example:
+//
+//   ACTION_P(Add, n) { return arg0 + n; }
+//
+// will allow you to write:
+//
+//   ...WillOnce(Add(5));
+//
+// Note that you don't need to provide the type of the parameter
+// either.  If you need to reference the type of a parameter named
+// 'foo', you can write 'foo_type'.  For example, in the body of
+// ACTION_P(Add, n) above, you can write 'n_type' to refer to the type
+// of 'n'.
+//
+// We also provide ACTION_P2, ACTION_P3, ..., up to ACTION_P10 to support
+// multi-parameter actions.
+//
+// For the purpose of typing, you can view
+//
+//   ACTION_Pk(Foo, p1, ..., pk) { ... }
+//
+// as shorthand for
+//
+//   template <typename p1_type, ..., typename pk_type>
+//   FooActionPk<p1_type, ..., pk_type> Foo(p1_type p1, ..., pk_type pk) { ... }
+//
+// In particular, you can provide the template type arguments
+// explicitly when invoking Foo(), as in Foo<long, bool>(5, false);
+// although usually you can rely on the compiler to infer the types
+// for you automatically.  You can assign the result of expression
+// Foo(p1, ..., pk) to a variable of type FooActionPk<p1_type, ...,
+// pk_type>.  This can be useful when composing actions.
+//
+// You can also overload actions with different numbers of parameters:
+//
+//   ACTION_P(Plus, a) { ... }
+//   ACTION_P2(Plus, a, b) { ... }
+//
+// While it's tempting to always use the ACTION* macros when defining
+// a new action, you should also consider implementing ActionInterface
+// or using MakePolymorphicAction() instead, especially if you need to
+// use the action a lot.  While these approaches require more work,
+// they give you more control on the types of the mock function
+// arguments and the action parameters, which in general leads to
+// better compiler error messages that pay off in the long run.  They
+// also allow overloading actions based on parameter types (as opposed
+// to just based on the number of parameters).
+//
+// CAVEAT:
+//
+// ACTION*() can only be used in a namespace scope.  The reason is
+// that C++ doesn't yet allow function-local types to be used to
+// instantiate templates.  The up-coming C++0x standard will fix this.
+// Once that's done, we'll consider supporting using ACTION*() inside
+// a function.

+//
+// The syntax:

+//
+// defines an action template that takes m explicit template
+// parameters and n value parameters.  name_i is the name of the i-th
+// template parameter, and kind_i specifies whether it's a typename,
+// an integral constant, or a template.  p_i is the name of the i-th
+// value parameter.
+//
+// Example:
+//
+//   // DuplicateArg<k, T>(output) converts the k-th argument of the mock
+//   // function to type T and copies it to *output.
+//   ACTION_TEMPLATE(DuplicateArg,
+//                   HAS_2_TEMPLATE_PARAMS(int, k, typename, T),
+//                   AND_1_VALUE_PARAMS(output)) {

+//   ...
+//     int n;
+//     EXPECT_CALL(mock, Foo(_, _))
+//         .WillOnce(DuplicateArg<1, unsigned char>(&n));
+//
+// To create an instance of an action template, write:
+//
+//   ActionName<t1, ..., t_m>(v1, ..., v_n)
+//
+// where the ts are the template arguments and the vs are the value
+// arguments.  The value argument types are inferred by the compiler.
+// If you want to explicitly specify the value argument types, you can
+// provide additional template arguments:
+//
+//   ActionName<t1, ..., t_m, u1, ..., u_k>(v1, ..., v_n)
+//
+// where u_i is the desired type of v_i.
+//
+// ACTION_TEMPLATE and ACTION/ACTION_P* can be overloaded on the
+// number of value parameters, but not on the number of template
+// parameters.  Without the restriction, the meaning of the following
+// is unclear:
+//
+//   OverloadedAction<int, bool>(x);
+//
+// Are we using a single-template-parameter action where 'bool' refers
+// to the type of x, or are we using a two-template-parameter action
+// where the compiler is asked to infer the type of x?
+//
+// Implementation notes:
+//
+// GMOCK_INTERNAL_*_HAS_m_TEMPLATE_PARAMS and
+// GMOCK_INTERNAL_*_AND_n_VALUE_PARAMS are internal macros for
+// implementing ACTION_TEMPLATE.  The main trick we use is to create
+// new macro invocations when expanding a macro.  For example, we have
+//
+//   #define ACTION_TEMPLATE(name, template_params, value_params)
+//       ... GMOCK_INTERNAL_DECL_##template_params ...
+//
+// which causes ACTION_TEMPLATE(..., HAS_1_TEMPLATE_PARAMS(typename, T), ...)
+// to expand to
+//
+//       ... GMOCK_INTERNAL_DECL_HAS_1_TEMPLATE_PARAMS(typename, T) ...
+//
+// Since GMOCK_INTERNAL_DECL_HAS_1_TEMPLATE_PARAMS is a macro, the
+// preprocessor will continue to expand it to
+//
+//       ... typename T ...
+//
+// This technique conforms to the C++ standard and is portable.  It
+// allows us to implement action templates using O(N) code, where N is
+// the maximum number of template/value parameters supported.  Without
+// using it, we'd have to devote O(N^2) amount of code to implement all

+//
+// The InvokeArgument<N>(a1, a2, ..., a_k) action invokes the N-th
+// (0-based) argument, which must be a k-ary callable, of the mock
+// function, with arguments a1, a2, ..., a_k.
+//
+// Notes:
+//
+//   1. The arguments are passed by value by default.  If you need to
+//   pass an argument by reference, wrap it inside ByRef().  For
+//   example,
+//
+//     InvokeArgument<1>(5, string("Hello"), ByRef(foo))
+//
+//   passes 5 and string("Hello") by value, and passes foo by
+//   reference.
+//
+//   2. If the callable takes an argument by reference but ByRef() is
+//   not used, it will receive the reference to a copy of the value,
+//   instead of the original value.  For example, when the 0-th
+//   argument of the mock function takes a const string&, the action
+//
+//     InvokeArgument<0>(string("Hello"))
+//
+//   makes a copy of the temporary string("Hello") object and passes a
+//   reference of the copy, instead of the original temporary object,
+//   to the callable.  This makes it easy for a user to define an
+//   InvokeArgument action from temporary values and have it performed
+//   later.

+// A MockFunction<F> class has one mock method whose type is F.  It is
+// useful when you just want your test code to emit some messages and
+// have Google Mock verify the right messages are sent (and perhaps at
+// the right times).  For example, if you are exercising code:
+//
+//   Foo(1);
+//   Foo(2);
+//   Foo(3);
+//
+// and want to verify that Foo(1) and Foo(3) both invoke
+// mock.Bar("a"), but Foo(2) doesn't invoke anything, you can write:
+//
+// TEST(FooTest, InvokesBarCorrectly) {
+//   MyMock mock;
+//   MockFunction<void(string check_point_name)> check;
+//   {
+//     InSequence s;
+//
+//     EXPECT_CALL(mock, Bar("a"));
+//     EXPECT_CALL(check, Call("1"));
+//     EXPECT_CALL(check, Call("2"));
+//     EXPECT_CALL(mock, Bar("a"));
+//   }
+//   Foo(1);
+//   check.Call("1");
+//   Foo(2);
+//   check.Call("2");
+//   Foo(3);
+// }
+//
+// The expectation spec says that the first Bar("a") must happen
+// before check point "1", the second Bar("a") must happen after check
+// point "2", and nothing should happen between the two check
+// points. The explicit check points make it easy to tell which
+// Bar("a") is called by which call to Foo().
+//
+// MockFunction<F> can also be used to exercise code that accepts
+// std::function<F> callbacks. To do so, use AsStdFunction() method
+// to create std::function proxy forwarding to original object's Call.
+// Example:
+//
+// TEST(FooTest, RunsCallbackWithBarArgument) {
+//   MockFunction<int(string)> callback;
+//   EXPECT_CALL(callback, Call("bar")).WillOnce(Return(1));
+//   Foo(callback.AsStdFunction());
+// }

+// Implements class templates NiceMock, NaggyMock, and StrictMock.
+//
+// Given a mock class MockFoo that is created using Google Mock,
+// NiceMock<MockFoo> is a subclass of MockFoo that allows
+// uninteresting calls (i.e. calls to mock methods that have no
+// EXPECT_CALL specs), NaggyMock<MockFoo> is a subclass of MockFoo
+// that prints a warning when an uninteresting call occurs, and
+// StrictMock<MockFoo> is a subclass of MockFoo that treats all
+// uninteresting calls as errors.
+//
+// Currently a mock is naggy by default, so MockFoo and
+// NaggyMock<MockFoo> behave like the same.  However, we will soon
+// switch the default behavior of mocks to be nice, as that in general
+// leads to more maintainable tests.  When that happens, MockFoo will
+// stop behaving like NaggyMock<MockFoo> and start behaving like
+// NiceMock<MockFoo>.
+//
+// NiceMock, NaggyMock, and StrictMock "inherit" the constructors of
+// their respective base class, with up-to 10 arguments.  Therefore
+// you can write NiceMock<MockFoo>(5, "a") to construct a nice mock
+// where MockFoo has a constructor that accepts (int, const char*),
+// for example.
+//
+// A known limitation is that NiceMock<MockFoo>, NaggyMock<MockFoo>,
+// and StrictMock<MockFoo> only works for mock methods defined using
+// the MOCK_METHOD* family of macros DIRECTLY in the MockFoo class.
+// If a mock method is defined in a base class of MockFoo, the "nice"
+// or "strict" modifier may not affect it, depending on the compiler.
+// In particular, nesting NiceMock, NaggyMock, and StrictMock is NOT
+// supported.
+//
+// Another known limitation is that the constructors of the base mock
+// cannot have arguments passed by non-const reference, which are
+// banned by the Google C++ style guide anyway.

+
+
+// The MATCHER* family of macros can be used in a namespace scope to
+// define custom matchers easily.
+//
+// Basic Usage
+// ===========
+//
+// The syntax
+//
+//   MATCHER(name, description_string) { statements; }
+//
+// defines a matcher with the given name that executes the statements,
+// which must return a bool to indicate if the match succeeds.  Inside
+// the statements, you can refer to the value being matched by 'arg',
+// and refer to its type by 'arg_type'.
+//
+// The description string documents what the matcher does, and is used
+// to generate the failure message when the match fails.  Since a
+// MATCHER() is usually defined in a header file shared by multiple
+// C++ source files, we require the description to be a C-string
+// literal to avoid possible side effects.  It can be empty, in which
+// case we'll use the sequence of words in the matcher name as the
+// description.
+//
+// For example:
+//
+//   MATCHER(IsEven, "") { return (arg % 2) == 0; }
+//
+// allows you to write
+//
+//   // Expects mock_foo.Bar(n) to be called where n is even.
+//   EXPECT_CALL(mock_foo, Bar(IsEven()));
+//
+// or,
+//
+//   // Verifies that the value of some_expression is even.
+//   EXPECT_THAT(some_expression, IsEven());
+//
+// If the above assertion fails, it will print something like:
+//
+//   Value of: some_expression
+//   Expected: is even
+//     Actual: 7
+//
+// where the description "is even" is automatically calculated from the
+// matcher name IsEven.
+//
+// Argument Type
+// =============
+//
+// Note that the type of the value being matched (arg_type) is
+// determined by the context in which you use the matcher and is
+// supplied to you by the compiler, so you don't need to worry about
+// declaring it (nor can you).  This allows the matcher to be
+// polymorphic.  For example, IsEven() can be used to match any type
+// where the value of "(arg % 2) == 0" can be implicitly converted to
+// a bool.  In the "Bar(IsEven())" example above, if method Bar()
+// takes an int, 'arg_type' will be int; if it takes an unsigned long,
+// 'arg_type' will be unsigned long; and so on.
+//
+// Parameterizing Matchers
+// =======================
+//
+// Sometimes you'll want to parameterize the matcher.  For that you
+// can use another macro:
+//
+//   MATCHER_P(name, param_name, description_string) { statements; }
+//
+// For example:
+//
+//   MATCHER_P(HasAbsoluteValue, value, "") { return abs(arg) == value; }
+//
+// will allow you to write:
+//
+//   EXPECT_THAT(Blah("a"), HasAbsoluteValue(n));
+//
+// which may lead to this message (assuming n is 10):
+//
+//   Value of: Blah("a")
+//   Expected: has absolute value 10
+//     Actual: -9
+//
+// Note that both the matcher description and its parameter are
+// printed, making the message human-friendly.
+//
+// In the matcher definition body, you can write 'foo_type' to
+// reference the type of a parameter named 'foo'.  For example, in the
+// body of MATCHER_P(HasAbsoluteValue, value) above, you can write
+// 'value_type' to refer to the type of 'value'.
+//
+// We also provide MATCHER_P2, MATCHER_P3, ..., up to MATCHER_P10 to
+// support multi-parameter matchers.
+//
+// Describing Parameterized Matchers
+// =================================
+//
+// The last argument to MATCHER*() is a string-typed expression.  The
+// expression can reference all of the matcher's parameters and a
+// special bool-typed variable named 'negation'.  When 'negation' is
+// false, the expression should evaluate to the matcher's description;
+// otherwise it should evaluate to the description of the negation of
+// the matcher.  For example,
+//
+//   using testing::PrintToString;
+//
+//   MATCHER_P2(InClosedRange, low, hi,
+//       string(negation ? "is not" : "is") + " in range [" +
+//       PrintToString(low) + ", " + PrintToString(hi) + "]") {
+//     return low <= arg && arg <= hi;
+//   }
+//   ...
+//   EXPECT_THAT(3, InClosedRange(4, 6));
+//   EXPECT_THAT(3, Not(InClosedRange(2, 4)));
+//
+// would generate two failures that contain the text:
+//
+//   Expected: is in range [4, 6]
+//   ...
+//   Expected: is not in range [2, 4]
+//
+// If you specify "" as the description, the failure message will
+// contain the sequence of words in the matcher name followed by the
+// parameter values printed as a tuple.  For example,
+//
+//   MATCHER_P2(InClosedRange, low, hi, "") { ... }
+//   ...
+//   EXPECT_THAT(3, InClosedRange(4, 6));
+//   EXPECT_THAT(3, Not(InClosedRange(2, 4)));
+//
+// would generate two failures that contain the text:
+//
+//   Expected: in closed range (4, 6)
+//   ...
+//   Expected: not (in closed range (2, 4))
+//
+// Types of Matcher Parameters
+// ===========================
+//
+// For the purpose of typing, you can view
+//
+//   MATCHER_Pk(Foo, p1, ..., pk, description_string) { ... }
+//
+// as shorthand for
+//
+//   template <typename p1_type, ..., typename pk_type>
+//   FooMatcherPk<p1_type, ..., pk_type>
+//   Foo(p1_type p1, ..., pk_type pk) { ... }
+//
+// When you write Foo(v1, ..., vk), the compiler infers the types of
+// the parameters v1, ..., and vk for you.  If you are not happy with
+// the result of the type inference, you can specify the types by
+// explicitly instantiating the template, as in Foo<long, bool>(5,
+// false).  As said earlier, you don't get to (or need to) specify
+// 'arg_type' as that's determined by the context in which the matcher
+// is used.  You can assign the result of expression Foo(p1, ..., pk)
+// to a variable of type FooMatcherPk<p1_type, ..., pk_type>.  This
+// can be useful when composing matchers.
+//
+// While you can instantiate a matcher template with reference types,
+// passing the parameters by pointer usually makes your code more
+// readable.  If, however, you still want to pass a parameter by
+// reference, be aware that in the failure message generated by the
+// matcher you will see the value of the referenced object but not its
+// address.
+//
+// Explaining Match Results
+// ========================
+//
+// Sometimes the matcher description alone isn't enough to explain why
+// the match has failed or succeeded.  For example, when expecting a
+// long string, it can be very helpful to also print the diff between
+// the expected string and the actual one.  To achieve that, you can
+// optionally stream additional information to a special variable
+// named result_listener, whose type is a pointer to class
+// MatchResultListener:
+//
+//   MATCHER_P(EqualsLongString, str, "") {
+//     if (arg == str) return true;
+//
+//     *result_listener << "the difference: "
+///                     << DiffStrings(str, arg);
+//     return false;
+//   }
+//
+// Overloading Matchers
+// ====================
+//
+// You can overload matchers with different numbers of parameters:
+//
+//   MATCHER_P(Blah, a, description_string1) { ... }
+//   MATCHER_P2(Blah, a, b, description_string2) { ... }
+//
+// Caveats
+// =======
+//
+// When defining a new matcher, you should also consider implementing
+// MatcherInterface or using MakePolymorphicMatcher().  These
+// approaches require more work than the MATCHER* macros, but also
+// give you more control on the types of the value being matched and
+// the matcher parameters, which may leads to better compiler error
+// messages when the matcher is used wrong.  They also allow
+// overloading matchers based on parameter types (as opposed to just
+// based on the number of parameters).
+//
+// MATCHER*() can only be used in a namespace scope.  The reason is
+// that C++ doesn't yet allow function-local types to be used to
+// instantiate templates.  The up-coming C++0x standard will fix this.
+// Once that's done, we'll consider supporting using MATCHER*() inside
+// a function.
+//
+// More Information

+// Environment-describing macros
+// -----------------------------
+//
+// Google Test can be used in many different environments.  Macros in
+// this section tell Google Test what kind of environment it is being
+// used in, such that Google Test can provide environment-specific
+// features and implementations.
+//
+// Google Test tries to automatically detect the properties of its
+// environment, so users usually don't need to worry about these
+// macros.  However, the automatic detection is not perfect.
+// Sometimes it's necessary for a user to define some of the following
+// macros in the build script to override Google Test's decisions.
+//
+// If the user doesn't define a macro in the list, Google Test will
+// provide a default definition.  After this header is #included, all
+// macros in this list will be defined to either 1 or 0.
+//
+// Notes to maintainers:
+//   - Each macro here is a user-tweakable knob; do not grow the list
+//     lightly.
+//   - Use #if to key off these macros.  Don't use #ifdef or "#if
+//     defined(...)", which will not work as these macros are ALWAYS
+//     defined.
+//
+//   GTEST_HAS_CLONE          - Define it to 1/0 to indicate that clone(2)
+//                              is/isn't available.
+//   GTEST_HAS_EXCEPTIONS     - Define it to 1/0 to indicate that exceptions
+//                              are enabled.
+//   GTEST_HAS_GLOBAL_STRING  - Define it to 1/0 to indicate that ::string
+//                              is/isn't available (some systems define
+//                              ::string, which is different to std::string).

+//                              DLL on Windows).
+//   GTEST_CREATE_SHARED_LIBRARY
+//                            - Define to 1 when compiling Google Test itself
+//                              as a shared library.
+
+// Platform-indicating macros
+// --------------------------
+//
+// Macros indicating the platform on which Google Test is being used
+// (a macro is defined to 1 if compiled on the given platform;
+// otherwise UNDEFINED -- it's never defined to 0.).  Google Test
+// defines these macros automatically.  Code outside Google Test MUST
+// NOT define them.
+//
+//   GTEST_OS_AIX      - IBM AIX
+//   GTEST_OS_CYGWIN   - Cygwin
+//   GTEST_OS_FREEBSD  - FreeBSD
+//   GTEST_OS_HPUX     - HP-UX
+//   GTEST_OS_LINUX    - Linux
+//     GTEST_OS_LINUX_ANDROID - Google Android
+//   GTEST_OS_MAC      - Mac OS X
+//     GTEST_OS_IOS    - iOS
+//   GTEST_OS_NACL     - Google Native Client (NaCl)
+//   GTEST_OS_OPENBSD  - OpenBSD
+//   GTEST_OS_QNX      - QNX
+//   GTEST_OS_SOLARIS  - Sun Solaris
+//   GTEST_OS_SYMBIAN  - Symbian
+//   GTEST_OS_WINDOWS  - Windows (Desktop, MinGW, or Mobile)
+//     GTEST_OS_WINDOWS_DESKTOP  - Windows Desktop
+//     GTEST_OS_WINDOWS_MINGW    - MinGW
+//     GTEST_OS_WINDOWS_MOBILE   - Windows Mobile
+//     GTEST_OS_WINDOWS_PHONE    - Windows Phone
+//     GTEST_OS_WINDOWS_RT       - Windows Store App/WinRT
+//   GTEST_OS_ZOS      - z/OS
+//
+// Among the platforms, Cygwin, Linux, Max OS X, and Windows have the
+// most stable support.  Since core members of the Google Test project
+// don't have access to other platforms, support for them may be less
+// stable.  If you notice any problems on your platform, please notify
+// googletestframework@googlegroups.com (patches for fixing them are
+// even more welcome!).
+//
+// It is possible that none of the GTEST_OS_* macros are defined.
+
+// Feature-indicating macros
+// -------------------------
+//
+// Macros indicating which Google Test features are available (a macro
+// is defined to 1 if the corresponding feature is supported;
+// otherwise UNDEFINED -- it's never defined to 0.).  Google Test
+// defines these macros automatically.  Code outside Google Test MUST
+// NOT define them.
+//
+// These macros are public so that portable tests can be written.
+// Such tests typically surround code using a feature with an #if
+// which controls that code.  For example:
+//
+// #if GTEST_HAS_DEATH_TEST
+//   EXPECT_DEATH(DoSomethingDeadly());
+// #endif
+//
+//   GTEST_HAS_COMBINE      - the Combine() function (for value-parameterized
+//                            tests)
+//   GTEST_HAS_DEATH_TEST   - death tests
+//   GTEST_HAS_PARAM_TEST   - value-parameterized tests
+//   GTEST_HAS_TYPED_TEST   - typed tests
+//   GTEST_HAS_TYPED_TEST_P - type-parameterized tests
+//   GTEST_IS_THREADSAFE    - Google Test is thread-safe.
+//   GTEST_USES_POSIX_RE    - enhanced POSIX regex is used. Do not confuse with
+//                            GTEST_HAS_POSIX_RE (see above) which users can
+//                            define themselves.
+//   GTEST_USES_SIMPLE_RE   - our own simple regex is used;
+//                            the above two are mutually exclusive.
+//   GTEST_CAN_COMPARE_NULL - accepts untyped NULL in EXPECT_EQ().
+
+// Misc public macros
+// ------------------
+//
+//   GTEST_FLAG(flag_name)  - references the variable corresponding to
+//                            the given Google Test flag.
+
+// Internal utilities
+// ------------------
+//
+// The following macros and utilities are for Google Test's INTERNAL
+// use only.  Code outside Google Test MUST NOT USE THEM DIRECTLY.
+//
+// Macros for basic C++ coding:
+//   GTEST_AMBIGUOUS_ELSE_BLOCKER_ - for disabling a gcc warning.
+//   GTEST_ATTRIBUTE_UNUSED_  - declares that a class' instances or a
+//                              variable don't have to be used.
+//   GTEST_DISALLOW_ASSIGN_   - disables operator=.
+//   GTEST_DISALLOW_COPY_AND_ASSIGN_ - disables copy ctor and operator=.
+//   GTEST_MUST_USE_RESULT_   - declares that a function's result must be used.
+//   GTEST_INTENTIONAL_CONST_COND_PUSH_ - start code section where MSVC C4127 is
+//                                        suppressed (constant conditional).
+//   GTEST_INTENTIONAL_CONST_COND_POP_  - finish code section where MSVC C4127
+//                                        is suppressed.
+//
+// C++11 feature wrappers:
+//
+//   testing::internal::move  - portability wrapper for std::move.
+//
+// Synchronization:
+//   Mutex, MutexLock, ThreadLocal, GetThreadCount()
+//                            - synchronization primitives.
+//
+// Template meta programming:
+//   is_pointer     - as in TR1; needed on Symbian and IBM XL C/C++ only.
+//   IteratorTraits - partial implementation of std::iterator_traits, which
+//                    is not available in libCstd when compiled with Sun C++.
+//
+// Smart pointers:
+//   scoped_ptr     - as in TR2.
+//
+// Regular expressions:
+//   RE             - a simple regular expression class using the POSIX
+//                    Extended Regular Expression syntax on UNIX-like
+//                    platforms, or a reduced regular exception syntax on
+//                    other platforms, including Windows.
+//
+// Logging:
+//   GTEST_LOG_()   - logs messages at the specified severity level.
+//   LogToStderr()  - directs all log messages to stderr.
+//   FlushInfoLog() - flushes informational log messages.
+//
+// Stdout and stderr capturing:
+//   CaptureStdout()     - starts capturing stdout.
+//   GetCapturedStdout() - stops capturing stdout and returns the captured
+//                         string.
+//   CaptureStderr()     - starts capturing stderr.
+//   GetCapturedStderr() - stops capturing stderr and returns the captured
+//                         string.
+//
+// Integer types:
+//   TypeWithSize   - maps an integer to a int type.
+//   Int32, UInt32, Int64, UInt64, TimeInMillis
+//                  - integers of known sizes.
+//   BiggestInt     - the biggest signed integer type.
+//
+// Command-line utilities:
+//   GTEST_DECLARE_*()  - declares a flag.
+//   GTEST_DEFINE_*()   - defines a flag.
+//   GetInjectableArgvs() - returns the command line as a vector of strings.
+//
+// Environment variable utilities:
+//   GetEnv()             - gets the value of an environment variable.
+//   BoolFromGTestEnv()   - parses a bool environment variable.
+//   Int32FromGTestEnv()  - parses an Int32 environment variable.
+//   StringFromGTestEnv() - parses a string environment variable.

+//   elements (and thus is invalid) when the expression is false.
+//
+// - The simpler definition
+//
+//    #define GTEST_COMPILE_ASSERT_(expr, msg) typedef char msg[(expr) ? 1 : -1]
+//
+//   does not work, as gcc supports variable-length arrays whose sizes
+//   are determined at run-time (this is gcc's extension and not part
+//   of the C++ standard).  As a result, gcc fails to reject the
+//   following code with the simple definition:
+//
+//     int foo;
+//     GTEST_COMPILE_ASSERT_(foo, msg); // not supposed to compile as foo is
+//                                      // not a compile-time constant.
+//
+// - By using the type CompileAssert<(bool(expr))>, we ensures that
+//   expr is a compile-time constant.  (Template arguments must be
+//   determined at compile-time.)
+//
+// - The outter parentheses in CompileAssert<(bool(expr))> are necessary
+//   to work around a bug in gcc 3.4.4 and 4.0.1.  If we had written
+//
+//     CompileAssert<bool(expr)>
+//
+//   instead, these compilers will refuse to compile
+//

+//   (They seem to think the ">" in "5 > 0" marks the end of the
+//   template argument list.)
+//
+// - The array size is (bool(expr) ? 1 : -1), instead of simply
+//
+//     ((expr) ? 1 : -1).

+// as that would require them to count the length.  Types<...> is much
+// easier to write, but generates horrible messages when there is a
+// compiler error, as gcc insists on printing out each template
+// argument, even if it has the default value (this means Types<int>
+// will appear as Types<int, None, None, ..., None> in the compiler
+// errors).
+//
+// Our solution is to combine the best part of the two approaches: a
+// user would write Types<T1, ..., TN>, and Google Test will translate
+// that to TypesN<T1, ..., TN> internally to make error messages
+// readable.  The translation is done by the 'type' member of the
+// Types template.

+//                parameter iff EXPECT_DEATH compiles with it.
+//   regex     -  A regex that a macro such as EXPECT_DEATH would use to test
+//                the output of statement.  This parameter has to be
+//                compiled but not evaluated by this macro, to ensure that
+//                this macro only accepts expressions that a macro such as
+//                EXPECT_DEATH would accept.
+//   terminator - Must be an empty statement for EXPECT_DEATH_IF_SUPPORTED
+//                and a return statement for ASSERT_DEATH_IF_SUPPORTED.
+//                This ensures that ASSERT_DEATH_IF_SUPPORTED will not
+//                compile inside functions where ASSERT_DEATH doesn't
+//                compile.
+//
+//  The branch that has an always false condition is used to ensure that
+//  statement and regex are compiled (and thus syntactically correct) but
+//  never executed. The unreachable code macro protects the terminator
+//  statement from generating an 'unreachable code' warning in case

+//
+//   1. It generates a warning if there is more than one active
+//   thread.  This is because it's safe to fork() or clone() only
+//   when there is a single thread.
+//
+//   2. The parent process clone()s a sub-process and runs the death
+//   test in it; the sub-process exits with code 0 at the end of the
+//   death test, if it hasn't exited already.
+//
+//   3. The parent process waits for the sub-process to terminate.
+//
+//   4. The parent process checks the exit code and error message of
+//   the sub-process.
+//
+// Examples:
+//
+//   ASSERT_DEATH(server.SendMessage(56, "Hello"), "Invalid port number");
+//   for (int i = 0; i < 5; i++) {
+//     EXPECT_DEATH(server.ProcessRequest(i),
+//                  "Invalid request .* in ProcessRequest()")
+//                  << "Failed to die on request " << i;
+//   }
+//
+//   ASSERT_EXIT(server.ExitNow(), ::testing::ExitedWithCode(0), "Exiting");
+//
+//   bool KilledBySIGHUP(int exit_code) {
+//     return WIFSIGNALED(exit_code) && WTERMSIG(exit_code) == SIGHUP;
+//   }
+//
+//   ASSERT_EXIT(client.HangUpServer(), KilledBySIGHUP, "Hanging up!");
+//
+// On the regular expressions used in death tests:
+//
+//   On POSIX-compliant systems (*nix), we use the <regex.h> library,
+//   which uses the POSIX extended regex syntax.
+//
+//   On other platforms (e.g. Windows), we only support a simple regex
+//   syntax implemented as part of Google Test.  This limited
+//   implementation should be enough most of the time when writing
+//   death tests; though it lacks many features you can find in PCRE
+//   or POSIX extended regex syntax.  For example, we don't support
+//   union ("x|y"), grouping ("(xy)"), brackets ("[xy]"), and
+//   repetition count ("x{5,7}"), among others.
+//
+//   Below is the syntax that we do support.  We chose it to be a
+//   subset of both PCRE and POSIX extended regex, so it's easy to
+//   learn wherever you come from.  In the following: 'A' denotes a
+//   literal character, period (.), or a single \\ escape sequence;
+//   'x' and 'y' denote regular expressions; 'm' and 'n' are for
+//   natural numbers.
+//
+//     c     matches any literal character c
+//     \\d   matches any decimal digit
+//     \\D   matches any character that's not a decimal digit
+//     \\f   matches \f
+//     \\n   matches \n
+//     \\r   matches \r
+//     \\s   matches any ASCII whitespace, including \n
+//     \\S   matches any character that's not a whitespace
+//     \\t   matches \t
+//     \\v   matches \v
+//     \\w   matches any letter, _, or decimal digit
+//     \\W   matches any character that \\w doesn't match
+//     \\c   matches any literal character c, which must be a punctuation
+//     .     matches any single character except \n
+//     A?    matches 0 or 1 occurrences of A
+//     A*    matches 0 or many occurrences of A
+//     A+    matches 1 or many occurrences of A
+//     ^     matches the beginning of a string (not that of each line)
+//     $     matches the end of a string (not that of each line)
+//     xy    matches x followed by y
+//
+//   If you accidentally use PCRE or POSIX extended regex features
+//   not implemented by us, you will get a run-time failure.  In that
+//   case, please try to rewrite your regular expression within the
+//   above syntax.
+//
+//   This implementation is *not* meant to be as highly tuned or robust
+//   as a compiled regex library, but should perform well enough for a
+//   death test, which already incurs significant overhead by launching
+//   a child process.
+//
+// Known caveats:
+//
+//   A "threadsafe" style death test obtains the path to the test
+//   program from argv[0] and re-executes it in the sub-process.  For
+//   simplicity, the current implementation doesn't search the PATH
+//   when launching the sub-process.  This means that the user must
+//   invoke the test program via a path that contains at least one
+//   path separator (e.g. path/to/foo_test and
+//   /absolute/path/to/bar_test are fine, but foo_test is not).  This
+//   is rarely a problem as people usually don't put the test binary
+//   directory in PATH.
+//
+// TODO(wan@google.com): make thread-safe death tests search the PATH.

+// Finally, you can use INSTANTIATE_TEST_CASE_P to instantiate the test

+// of functions for generating test parameters. They return what we call
+// (surprise!) parameter generators. Here is a  summary of them, which
+// are all in the testing namespace:
+//
+//
+//  Range(begin, end [, step]) - Yields values {begin, begin+step,
+//                               begin+step+step, ...}. The values do not
+//                               include end. step defaults to 1.
+//  Values(v1, v2, ..., vN)    - Yields values {v1, v2, ..., vN}.
+//  ValuesIn(container)        - Yields values from a C-style array, an STL
+//  ValuesIn(begin,end)          container, or an iterator range [begin, end).
+//  Bool()                     - Yields sequence {false, true}.
+//  Combine(g1, g2, ..., gN)   - Yields all combinations (the Cartesian product
+//                               for the math savvy) of the values generated
+//                               by the N generators.
+//
+// For more details, see comments at the definitions of these functions below
+// in this file.

+// The following statement will instantiate tests from the FooTest test case
+// each with parameter values "meeny", "miny", and "moe".
+
+INSTANTIATE_TEST_CASE_P(InstantiationName,
+                        FooTest,

+
+// To distinguish different instances of the pattern, (yes, you
+// can instantiate it more then once) the first argument to the
+// INSTANTIATE_TEST_CASE_P macro is a prefix that will be added to the
+// actual test case name. Remember to pick unique prefixes for different
+// instantiations. The tests from the instantiation above will have
+// these names:

+//    * InstantiationName/FooTest.HasBlahBlah/1 for "miny"
+//    * InstantiationName/FooTest.HasBlahBlah/2 for "moe"
+//
+// You can use these names in --gtest_filter.
+//
+// This statement will instantiate all tests from FooTest again, each
+// with parameter values "cat" and "dog":

+//    * AnotherInstantiationName/FooTest.HasBlahBlah/0 for "cat"
+//    * AnotherInstantiationName/FooTest.HasBlahBlah/1 for "dog"
+//
+// Please note that INSTANTIATE_TEST_CASE_P will instantiate all tests
+// in the given test case, whether their definitions come before or
+// AFTER the INSTANTIATE_TEST_CASE_P statement.
+//
+// Please also note that generator expressions (including parameters to the
+// generators) are evaluated in InitGoogleTest(), after main() has started.
+// This allows the user on one hand, to adjust generator parameters in order
+// to dynamically determine a set of tests to run and on the other hand,
+// give the user a chance to inspect the generated tests with Google Test
+// reflection API before RUN_ALL_TESTS() is executed.
+//
+// You can see samples/sample7_unittest.cc and samples/sample8_unittest.cc
+// for more examples.
+//
+// In the future, we plan to publish the API for defining new parameter
+// generators. But for now this interface remains part of the internal
+// implementation and is subject to change.
+//
+//
+// A parameterized test fixture must be derived from testing::Test and from
+// testing::WithParamInterface<T>, where T is the type of the parameter
+// values. Inheriting from TestWithParam<T> satisfies that requirement because
+// TestWithParam<T> inherits from both Test and WithParamInterface. In more
+// complicated hierarchies, however, it is occasionally useful to inherit
+// separately from Test and WithParamInterface. For example:
+
+class BaseTest : public ::testing::Test {
+  // You can inherit all the usual members for a non-parameterized test
+  // fixture here.
+};
+
+class DerivedTest : public BaseTest, public ::testing::WithParamInterface<int> {
+  // The usual test fixture members go here too.
+};
+
+TEST_F(BaseTest, HasFoo) {
+  // This is an ordinary non-parameterized test.
+}
+
+TEST_P(DerivedTest, DoesBlah) {
+  // GetParam works just the same here as if you inherit from TestWithParam.
+  EXPECT_TRUE(foo.Blah(GetParam()));

+// A "smart" pointer type with reference tracking.  Every pointer to a
+// particular object is kept on a circular linked list.  When the last pointer
+// to an object is destroyed or reassigned, the object is deleted.
+//
+// Used properly, this deletes the object when the last reference goes away.
+// There are several caveats:
+// - Like all reference counting schemes, cycles lead to leaks.
+// - Each smart pointer is actually two pointers (8 bytes instead of 4).
+// - Every time a pointer is assigned, the entire list of pointers to that
+//   object is traversed.  This class is therefore NOT SUITABLE when there
+//   will often be more than two or three pointers to a particular object.
+// - References are only tracked as long as linked_ptr<> objects are copied.
+//   If a linked_ptr<> is converted to a raw pointer and back, BAD THINGS
+//   will happen (double deletion).
+//
+// A good use of this class is storing object references in STL containers.
+// You can safely put linked_ptr<> in a vector<>.
+// Other uses may not be as good.
+//
+// Note: If you use an incomplete type with linked_ptr<>, the class
+// *containing* linked_ptr<> must have a constructor and destructor (even
+// if they do nothing!).
+//
+// Bill Gibbons suggested we use something like this.
+//
+// Thread Safety:
+//   Unlike other linked_ptr implementations, in this implementation
+//   a linked_ptr object is thread-safe in the sense that:
+//     - it's safe to copy linked_ptr objects concurrently,
+//     - it's safe to copy *from* a linked_ptr and read its underlying
+//       raw pointer (e.g. via get()) concurrently, and
+//     - it's safe to write to two linked_ptrs that point to the same
+//       shared object concurrently.
+// TODO(wan@google.com): rename this to safe_linked_ptr to avoid
+// confusion with normal linked_ptr.

+// This file implements a universal value printer that can print a
+// value of any type T:
+//
+//   void ::testing::internal::UniversalPrinter<T>::Print(value, ostream_ptr);
+//
+// A user can teach this function how to print a class type T by
+// defining either operator<<() or PrintTo() in the namespace that
+// defines T.  More specifically, the FIRST defined function in the
+// following list will be used (assuming T is defined in namespace
+// foo):
+//
+//   1. foo::PrintTo(const T&, ostream*)
+//   2. operator<<(ostream&, const T&) defined in either foo or the
+//      global namespace.
+//
+// If none of the above is defined, it will print the debug string of
+// the value if it is a protocol buffer, or print the raw bytes in the
+// value otherwise.
+//
+// To aid debugging: when T is a reference type, the address of the
+// value is also printed; when T is a (const) char pointer, both the
+// pointer value and the NUL-terminated string it points to are
+// printed.
+//
+// We also provide some convenient wrappers:
+//
+//   // Prints a value to a string.  For a (const or not) char
+//   // pointer, the NUL-terminated string (but not the pointer) is
+//   // printed.
+//   std::string ::testing::PrintToString(const T& value);
+//
+//   // Prints a value tersely: for a reference type, the referenced
+//   // value (but not the address) is printed; for a (const or not) char
+//   // pointer, the NUL-terminated string (but not the pointer) is
+//   // printed.
+//   void ::testing::internal::UniversalTersePrint(const T& value, ostream*);
+//
+//   // Prints value using the type inferred by the compiler.  The difference
+//   // from UniversalTersePrint() is that this function prints both the
+//   // pointer and the NUL-terminated string for a (const or not) char pointer.
+//   void ::testing::internal::UniversalPrint(const T& value, ostream*);
+//
+//   // Prints the fields of a tuple tersely to a string vector, one
+//   // element for each field. Tuple support must be enabled in
+//   // gtest-port.h.
+//   std::vector<string> UniversalTersePrintTupleFieldsToStrings(
+//       const Tuple& value);
+//
+// Known limitation:
+//
+// The print primitives print the elements of an STL-style container
+// using the compiler-inferred type of *iter where iter is a
+// const_iterator of the container.  When const_iterator is an input
+// iterator but not a forward iterator, this inferred type may not
+// match value_type, and the print output may be incorrect.  In
+// practice, this is rarely a problem as for most containers
+// const_iterator is a forward iterator.  We'll fix this if there's an
+// actual need for it.  Note that this fix cannot rely on value_type
+// being defined as many user-defined container types don't have
+// value_type.

+// Synopsis:

+//   - returns a generator producing sequences with elements coming from
+//     the Cartesian product of elements from the sequences generated by
+//     gen1, gen2, ..., genN. The sequence elements will have a type of
+//     tuple<T1, T2, ..., TN> where T1, T2, ..., TN are the types
+//     of elements from sequences produces by gen1, gen2, ..., genN.
+//
+// Combine can have up to 10 arguments. This number is currently limited
+// by the maximum number of elements in the tuple implementation used by Google
+// Test.
+//
+// Example:
+//
+// This will instantiate tests in test case AnimalTest each one with
+// the parameter values tuple("cat", BLACK), tuple("cat", WHITE),
+// tuple("dog", BLACK), and tuple("dog", WHITE):
+//
+// enum Color { BLACK, GRAY, WHITE };

+//
+// This will instantiate tests in FlagDependentTest with all variations of two
+// Boolean flags:
+//
+// class FlagDependentTest
+//     : public testing::TestWithParam<tuple<bool, bool> > {
+//   virtual void SetUp() {
+//     // Assigns external_flag_1 and external_flag_2 values from the tuple.

+// Type-parameterized tests are abstract test patterns parameterized
+// by a type.  Compared with typed tests, type-parameterized tests
+// allow you to define the test pattern without knowing what the type
+// parameters are.  The defined pattern can be instantiated with
+// different types any number of times, in any number of translation
+// units.
+//
+// If you are designing an interface or concept, you can define a
+// suite of type-parameterized tests to verify properties that any
+// valid implementation of the interface/concept should have.  Then,
+// each implementation can easily instantiate the test suite to verify
+// that it conforms to the requirements, without having to write
+// similar tests repeatedly.  Here's an example:
+
+#if 0
+
+// First, define a fixture class template.  It should be parameterized
+// by a type.  Remember to derive it from testing::Test.
+template <typename T>
+class FooTest : public testing::Test {
+  ...

+// Next, declare that you will define a type-parameterized test case
+// (the _P suffix is for "parameterized" or "pattern", whichever you
+// prefer):
+TYPED_TEST_CASE_P(FooTest);

+// for this type-parameterized test case as you want.

+  // Inside a test, refer to TypeParam to get the type parameter.
+  TypeParam n = 0;
+  ...
+}
+
+TYPED_TEST_P(FooTest, HasPropertyA) { ... }

+// case.

+// the assertion wasn't successful, the AssertionResult object
+// remembers a non-empty message that describes how it failed.
+//
+// To create an instance of this class, use one of the factory functions
+// (AssertionSuccess() and AssertionFailure()).
+//
+// This class is useful for two purposes:
+//   1. Defining predicate functions to be used with Boolean test assertions
+//      EXPECT_TRUE/EXPECT_FALSE and their ASSERT_ counterparts
+//   2. Defining predicate-format functions to be
+//      used with predicate assertions (ASSERT_PRED_FORMAT*, etc).
+//
+// For example, if you define IsEven predicate:
+//
+//   testing::AssertionResult IsEven(int n) {
+//     if ((n % 2) == 0)
+//       return testing::AssertionSuccess();
+//     else
+//       return testing::AssertionFailure() << n << " is odd";
+//   }
+//
+// Then the failed expectation EXPECT_TRUE(IsEven(Fib(5)))
+// will print the message
+//
+//   Value of: IsEven(Fib(5))
+//     Actual: false (5 is odd)
+//   Expected: true
+//
+// instead of a more opaque
+//
+//   Value of: IsEven(Fib(5))
+//     Actual: false
+//   Expected: true
+//
+// in case IsEven is a simple Boolean predicate.
+//
+// If you expect your predicate to be reused and want to support informative
+// messages in EXPECT_FALSE and ASSERT_FALSE (negative assertions show up
+// about half as often as positive ones in our tests), supply messages for
+// both success and failure cases:
+//
+//   testing::AssertionResult IsEven(int n) {
+//     if ((n % 2) == 0)
+//       return testing::AssertionSuccess() << n << " is even";
+//     else
+//       return testing::AssertionFailure() << n << " is odd";
+//   }
+//
+// Then a statement EXPECT_FALSE(IsEven(Fib(6))) will print
+//
+//   Value of: IsEven(Fib(6))
+//     Actual: true (8 is even)
+//   Expected: false
+//
+// NB: Predicates that support negative Boolean assertions have reduced
+// performance in positive ones so be careful not to use them in tests
+// that have lots (tens of thousands) of positive Boolean assertions.
+//
+// To use this class with EXPECT_PRED_FORMAT assertions such as:
+//
+//   // Verifies that Foo() returns an even number.
+//   EXPECT_PRED_FORMAT1(IsEven, Foo());
+//
+// you need to define:
+//
+//   testing::AssertionResult IsEven(const char* expr, int n) {
+//     if ((n % 2) == 0)
+//       return testing::AssertionSuccess();
+//     else
+//       return testing::AssertionFailure()
+//         << "Expected: " << expr << " is even\n  Actual: it's " << n;
+//   }
+//
+// If Foo() returns 5, you will see the following message:
+//
+//   Expected: Foo() is even
+//     Actual: it's 5

+//
+// Note:

+//   1. It is possible to make a user-defined type work with
+//   {ASSERT|EXPECT}_??(), but that requires overloading the
+//   comparison operators and is thus discouraged by the Google C++
+//   Usage Guide.  Therefore, you are advised to use the
+//   {ASSERT|EXPECT}_TRUE() macro to assert that two objects are
+//   equal.
+//
+//   2. The {ASSERT|EXPECT}_??() macros do pointer comparisons on
+//   pointers (in particular, C strings).  Therefore, if you use it
+//   with two C strings, you are testing how their locations in memory
+//   are related, not how their content is related.  To compare two C
+//   strings by content, use {ASSERT|EXPECT}_STR*().
+//
+//   3. {ASSERT|EXPECT}_EQ(v1, v2) is preferred to
+//   {ASSERT|EXPECT}_TRUE(v1 == v2), as the former tells you
+//   what the actual value is when it fails, and similarly for the
+//   other comparisons.
