+Version 7.20.1 (14 April 2010)
+
+Daniel Stenberg (9 Apr 2010)
+- Prefixing the FTP quote commands with an asterisk really only worked for the
+  postquote actions. This is now fixed and test case 227 has been extended to
+  verify.
+
+Kamil Dudka (4 Apr 2010)
+- Eliminated a race condition in Curl_resolv_timeout().
+
+- Refactorized interface of Curl_ssl_recv()/Curl_ssl_send().
+
+- libcurl-NSS now provides more accurate messages and error codes in case of
+  client certificate problem.  Either during connection, or transfer phase.
+
+Daniel Stenberg (1 Apr 2010)
+- Matt Wixson found and fixed a bug in the SCP/SFTP area where the code
+  treated a 0 return code from libssh2 to be the same as EAGAIN while in
+  reality it isn't. The problem caused a hang in SFTP transfers from a
+  MessageWay server.
+
+Daniel Stenberg (28 Mar 2010)
+- Ben Greear: If you pass a URL to pop3 that does not contain a message ID as
+  part of the URL, it would previously ask for 'INBOX' which just causes the
+  pop3 server to return an error.
+    
+  Now libcurl treats en empty message ID as a request for LIST (list of pop3
+  message IDs).  User's code could then parse this and download individual
+  messages as desired.
+
+Daniel Stenberg (27 Mar 2010)
+- Ben Greear brought a patch that from now on allows all protocols to specify
+  name and user within the URL, in the same manner HTTP and FTP have been
+  allowed to in the past - although far from all of the libcurl supported
+  protocls actually have that feature in their URL definition spec.
+
+Daniel Stenberg (26 Mar 2010)
+- Ben Greear brought code that makes the rate limiting code for the easy
+  interface a bit smoother as it introduces sub-second sleeps during it and it
+  also takes the buffer sizes into account.
+
+Daniel Stenberg (24 Mar 2010)
+- Bob Richmond: There's an annoying situation where libcurl will read new HTTP
+  response data from a socket, then check if it's a timeout if one is set. If
+  the last packet received constitutes the end of the response body, libcurl
+  still treats it as a timeout condition and reports a message like:
+
+  "Operation timed out after 3000 milliseconds with 876 out of 876 bytes 
+  received"
+
+  It should only a timeout if the timer lapsed and we DIDN'T receive the end
+  of the response body yet.
+
+- Christopher Conroy fixed a problem with RTSP and GET_PARAMETER reported
+  to us by Massimo Callegari. There's a new test case 572 that verifies this
+  now.
+
+- The 'ares' subtree has been removed from the source repository. It was
+  always a separate project that sort of piggybacked on the curl project since
+  the dawn of times and now the time has come for it to go stand on its own
+  legs and continue living its own life. All details on c-ares and its new
+  source code repository is found at http://c-ares.haxx.se/
+
+Daniel Stenberg (23 Mar 2010)
+- Kenny To filed the bug report #2963679 with patch to fix a problem he
+  experienced with doing multi interface HTTP POST over a proxy using
+  PROXYTUNNEL. He found a case where it would connect fine but bits.tcpconnect
+  was not set correct so libcurl didn't work properly.
+
+  (http://curl.haxx.se/bug/view.cgi?id=2963679)
+
+- Akos Pasztory filed debian bug report #572276
+  http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=572276 mentioning a problem
+  with a resource that returns chunked-encoded _and_ with a Content-Length
+  and libcurl failed to properly ignore the latter information.
+
+- Hauke Duden provided an example program that made the multi interface crash.
+  His example simply used the multi interface and did first one FTP transfer
+  and after completion it used a second easy handle and did another FTP
+  transfer on the same FTP server.
+
+  This triggered a bug in the "delayed easy handle kill" system that curl
+  uses: when an FTP connection is left alive it must keep an easy handle
+  around internally - only for the purpose of having an easy handle when it
+  later disconnects it. The code assumed that when the easy handle was removed
+  and an internal reference was made, that version could be killed later on
+  when a new easy handle came using the same connection. This was wrong as
+  Hauke's example showed that the removed handle wasn't killed for real until
+  later. This caused a double close attempt => segfault.
+
+Daniel Stenberg (22 Mar 2010)
+- Thomas Lopatic fixed the alarm()-based DNS timeout:
+
+  Looking at the code of Curl_resolv_timeout() in hostip.c, I think that in
+  case of a timeout, the signal handler for SIGALRM never gets removed. I
+  think that in my case it gets executed at some point later on when execution
+  has long left Curl_resolv_timeout() or even the cURL library.
+  
+  The code that is jumped to with siglongjmp() simply sets the error message
+  to "name lookup timed out" and then returns with CURLRESOLV_ERROR. I guess
+  that instead of simply returning without cleaning up, the code should have a
+  goto that jumps to the spot right after the call to Curl_resolv().
+
+Kamil Dudka (22 Mar 2010)
+- Douglas Steinwand contributed a patch fixing insufficient initialization in
+  Curl_clone_ssl_config()
+
+Daniel Stenberg (21 Mar 2010)
+- Ben Greear improved TFTP: the error code returning and the treatment
+  of TSIZE == 0 when uploading.
+
+- We've switched from CVS to git. See http://curl.haxx.se/source.html
+
+Kamil Dudka (19 Mar 2010)
+- Improved Curl_read() to not ignore the error returned from Curl_ssl_recv().
+
+Daniel Stenberg (15 Mar 2010)
+- Constantine Sapuntzakis brought a patch:
+
+  The problem mentioned on Dec 10 2009
+  (http://curl.haxx.se/bug/view.cgi?id=2905220) was only partially fixed.
+  Partially because an easy handle can be associated with many connections in
+  the cache (e.g. if there is a redirect during the lifetime of the easy
+  handle).  The previous patch only cleaned up the first one. The new fix now
+  removes the easy handle from all connections, not just the first one.
+
+Daniel Stenberg (6 Mar 2010)
+- Ben Greear brought a patch that fixed the rate limiting logic for TFTP when
+  the easy interface was used.
+
+Daniel Stenberg (5 Mar 2010)
+- Daniel Johnson provided fixes for building curl with the clang compiler.
+
+Yang Tse (5 Mar 2010)
+- Constantine Sapuntzakis detected and fixed a double free in builds done
+  with threaded resolver enabled (Windows default configuration) that would
+  get triggered when a curl handle is closed while doing DNS resolution.
+
+Daniel Stenberg (2 Mar 2010)
+- [Daniel Johnson] I've been trying to build libcurl with clang on Darwin and
+  ran into some issues with the GSSAPI tests in configure.ac. The tests first
+  try to determine the include dirs and libs and set CPPFLAGS and LIBS
+  accordingly. It then checks for the headers and finally sets LIBS a second
+  time, causing the libs to be included twice. The first setting of LIBS seems
+  redundant and should be left out, since the first part is otherwise just
+  about finding headers.
+
+  My second issue is that 'krb5-config --libs gssapi' on Darwin is less than
+  useless and returns junk that, while it happens to work with gcc, causes
+  clang to choke. For example, --libs returns $CFLAGS along with the libs,
+  which is really retarded. Simply setting 'LIBS="$LIBS -lgssapi_krb5
+  -lresolv"' on Darwin is sufficient.
+
+- Based on patch provided by Jacob Moshenko, the transfer logic now properly
+  makes sure that when using sub-second timeouts, there's no final bad 1000ms
+  wait. Previously, a sub-second timeout would often make the elapsed time end
+  up the time rounded up to the nearest second (e.g. 1s for 200ms timeout)
+
+- Andrei Benea filed bug report #2956698 and pointed out that the
+  CURLOPT_CERTINFO feature leaked memory due to a missing OpenSSL function
+  call. He provided the patch to fix it too.
+
+  http://curl.haxx.se/bug/view.cgi?id=2956698
+
+- Markus Duft pointed out in bug #2961796 that even though Interix has a
+  poll() function it doesn't quite work the way we want it so we must disable
+  it, and he also provided a patch for it.
+
+  http://curl.haxx.se/bug/view.cgi?id=2961796
+
+- Made the pingpong timeout code properly deal with the response timeout AND
+  the global timeout if set. Also, as was reported in the bug report #2956437
+  by Ryan Chan, the time stamp to use as basis for the per command timeout was
+  not set properly in the DONE phase for FTP (and not for SMTP) so I fixed
+  that just now. This was a regression compared to 7.19.7 due to the
+  conversion of FTP code over to the generic pingpong concepts.
+
+  http://curl.haxx.se/bug/view.cgi?id=2956437
+
+Daniel Stenberg (1 Mar 2010)
+- Ben Greear provided an update for TFTP that fixes upload.
+
+- Wesley Miaw reported bug #2958179 which identified a case of looping during
+  OpenSSL based SSL handshaking even though the multi interface was used and
+  there was no good reason for it.
+
+  http://curl.haxx.se/bug/view.cgi?id=2958179
+
+Daniel Stenberg (26 Feb 2010)
+- Pat Ray in bug #2958474 pointed out an off-by-one case when receiving a
+  chunked-encoding trailer.
+
+  http://curl.haxx.se/bug/view.cgi?id=2958474
+
+Daniel Fandrich (25 Feb 2010)
+- Fixed a couple of out of memory leaks and a segfault in the SMTP & IMAP code.
+
+Yang Tse (25 Feb 2010)
+- I fixed bug report #2958074 indicating
+  (http://curl.haxx.se/bug/view.cgi?id=2958074) that curl on Windows with
+  option --trace-time did not use local time when timestamping trace lines.
+  This could also happen on other systems depending on time souurce.
+
+Patrick Monnerat (22 Feb 2010)
+- Proper handling of STARTTLS on SMTP, taking CURLUSESSL_TRY into account.
+- SMTP falls back to RFC821 HELO when EHLO fails (and SSL is not required).
+- Use of true local host name (i.e.: via gethostname()) when available, as
+  default argument to SMTP HELO/EHLO.
+- Test case 804 for HELO fallback.
+
+Daniel Stenberg (20 Feb 2010)
+- Fixed the SMTP compliance by making sure RCPT TO addresses are specified
+  properly in angle brackets. Recipients provided with CURLOPT_MAIL_RCPT now
+  get angle bracket wrapping automatically by libcurl unless the recipient
+  starts with an angle bracket as then the app is assumed to deal with that
+  properly on its own.
+
+- I made the SMTP code expect a 250 response back from the server after the
+  full DATA has been sent, and I modified the test SMTP server to also send
+  that response. As usual, the DONE operation that is made after a completed
+  transfer is still not doable in a non-blocking way so this waiting for 250
+  is unfortunately made blockingly.
+
+Yang Tse (14 Feb 2010)
+- Overhauled test suite getpart() function. Fixing potential out of bounds
+  stack and memory overwrites triggered with huge test case definitions.
+
+Daniel Stenberg (13 Feb 2010)
+- Martin Hager reported and fixed a problem with a missing quote in libcurl.m4
+
+  (http://curl.haxx.se/bug/view.cgi?id=2951319)
+
+- Tom Donovan fixed the CURL_FORMAT_* defines when building with cmake.
+
+  (http://curl.haxx.se/bug/view.cgi?id=2951269)
+
+Daniel Stenberg (12 Feb 2010)
+- Jack Zhang reported a problem with SMTP: we wrongly used multiple addresses
+  in the same RCPT TO line, when they should be sent in separate single
+  commands. I updated test case 802 to verify this.
+
+- I also fixed a bad use of my_setopt_str() of CURLOPT_MAIL_RCPT in the curl
+  tool which made it try to output it as string for the --libcurl feature
+  which could lead to crashes.
+
+Yang Tse (11 Feb 2010)
+- Steven M. Schweda fixed VMS builder bad behavior when used in a batch job,
+  removed obsolete batch_compile.com and defines.com and updated VMS readme.

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

ares/README

@@ -1,46 +0,0 @@
-This is c-ares, a forked version of the original ares. The original ares
-README follows below, the c-ares specific details are in README.cares
-
-====================================================================
-
-This is ares, an asynchronous resolver library.  It is intended for
-applications which need to perform DNS queries without blocking, or
-need to perform multiple DNS queries in parallel.  The primary
-examples of such applications are servers which communicate with
-multiple clients and programs with graphical user interfaces.
-
-This library implementation is not especially portable to crufty old
-systems like SunOS 4.  It assumes a compiler which can handle ANSI C
-syntax, a system malloc which properly handles realloc(NULL, foo) and
-free(NULL), and a reasonably up-to-date <arpa/nameser.h>.
-
-I have attempted to preserve the externally visible behavior of the
-BIND resolver in nearly all respects.  The API of the library is, of
-course, very different from the synchronous BIND API; instead of
-invoking a function like res_send() and getting a return value back
-indicating the number of bytes in the response, you invoke a function
-like ares_send() and give it a callback function to invoke when the
-response arrives.  You then have to select() on the file descriptors
-indicated by ares_fds(), with a timeout given by ares_timeout().  You
-call ares_process() when select() returns.
-
-Some features are missing from the current version of ares, relative
-to the BIND resolver:
-
-	* There is no IPV6 support.                [not true for c-ares]
-	* There is no hostname verification.
-	* There is no logging of unexpected events.
-	* There is no debugging-oriented logging.

-libares requires an ANSI compiler to compile and use.  To build the
-library, just run "./configure" and "make".  To install it, run "make
-install".  Run "./configure --help" to see a list of options you can
-provide to configure to change how the library builds.  libares has no
-data files, so you can move the include file and library around freely
-without leaving behind any dependencies on old paths.  Building the
-library will also build the "adig" program, a little toy for trying
-out the library.  It doesn't get installed.
-
-libares is distributed at athena-dist.mit.edu:pub/ATHENA/ares.  Please
-send bug reports and comments to ghudson@mit.edu.

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

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

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

-.B #include <ares.h>
-.PP
-.B int ares_dup(ares_channel *\fIdest\fP, ares_channel \fIsource\fP)
-.fi
-.SH DESCRIPTION
-The \fBares_dup(3)\fP function duplicates an existing communications channel
-for name service lookups.  If it returns successfully, \fBares_dup(3)\fP will
-set the variable pointed to by \fIdest\fP to a handle used to identify the
-name service channel.  The caller should invoke \fIares_destroy(3)\fP on the
-handle when the channel is no longer needed.
-
-The \fBares_dup_options\fP function also initializes a name service channel,
-with additional options set exactly as the \fIsource\fP channel has them
-configured.

-.TH ARES_EXPAND_NAME 3 "20 Nov 2009"
-.SH NAME
-ares_expand_name \- Expand a DNS-encoded domain name
-.SH SYNOPSIS
-.nf
-.B #include <ares.h>
-.PP
-.B int ares_expand_name(const unsigned char *\fIencoded\fP,
-.B      const unsigned char *\fIabuf\fP, int \fIalen\fP, char **\fIs\fP,
-.B 	long *\fIenclen\fP)
-.fi
-.SH DESCRIPTION
-The
-.B ares_expand_name
-function converts a DNS-encoded domain name to a dot-separated C
-string.  The argument
-.I encoded
-gives the beginning of the encoded domain name, and the arguments
-.I abuf
-and
-.I alen
-give the containing message buffer (necessary for the processing of
-indirection pointers within the encoded domain name).  The result is
-placed in a NUL-terminated allocated buffer, a pointer to which is
-stored in the variable pointed to by
-.IR s .
-The length of the encoded name is stored in the variable pointed to by
-.I enclen
-so that the caller can advance past the encoded domain name to read
-further data in the message.
-.SH RETURN VALUES
-.B ares_expand_name
-can return any of the following values:
-.TP 15
-.B ARES_SUCCESS
-Expansion of the encoded name succeeded.
-.TP 15
-.B ARES_EBADNAME
-The encoded domain name was malformed and could not be expanded.
-.TP 15
-.B ARES_ENOMEM
-Memory was exhausted.

-.TH ARES_EXPAND_NAME 3 "20 Nov 2009"
-.SH NAME
-ares_expand_string \- Expand a length encoded string
-.SH SYNOPSIS
-.nf
-.B #include <ares.h>
-.PP
-.B int ares_expand_string(const unsigned char *\fIencoded\fP,
-.B      const unsigned char *\fIabuf\fP, int \fIalen\fP, unsigned char **\fIs\fP,
-.B 	long *\fIenclen\fP)
-.fi
-.SH DESCRIPTION
-The
-.B ares_expand_string
-function converts a length encoded string to a NUL-terminated C
-string.  The argument
-.I encoded
-gives the beginning of the encoded string, and the arguments
-.I abuf
-and
-.I alen
-give the containing message buffer (necessary for the processing of
-indirection pointers within the encoded domain name).  The result is
-placed in a NUL-terminated allocated buffer, a pointer to which is
-stored in the variable pointed to by
-.IR s .
-The length of the encoded string is stored in the variable pointed to by
-.I enclen
-so that the caller can advance past the encoded string to read
-further data in the message.
-.SH RETURN VALUES
-.B ares_expand_string
-can return any of the following values:
-.TP 15
-.B ARES_SUCCESS
-Expansion of the encoded string succeeded.
-.TP 15
-.B ARES_EBADSTR
-The encoded string was malformed and could not be expanded.
-.TP 15
-.B ARES_ENOMEM
-Memory was exhausted.

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

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

-.TH ARES_GETHOSTBYNAME 3 "25 July 1998"
-.SH NAME
-ares_gethostbyname_file \- Lookup a name in the system's hosts file
-.SH SYNOPSIS
-.nf
-.B #include <ares.h>
-.PP
-.B int ares_gethostbyname_file(ares_channel \fIchannel\fP, const char *\fIname\fP,
-.B 	int \fIfamily\fP, struct hostent **host)
-.fi
-.SH DESCRIPTION
-The
-.B ares_gethostbyname_file
-function performs a host lookup by name against the system's hosts file (or equivalent local hostname database).  
-The
-.IR channel
-parameter is required, but no asynchronous queries are performed.  Instead, the
-lookup is done via the same mechanism used to perform 'f' lookups
-(see the
-.I lookups
-options field in \fIares_init_options(3)\fP).
-The parameter
-.I name
-gives the hostname as a NUL-terminated C string, and
-.I family
-gives the desired type of address for the resulting host entry.  
-.PP
-The return value indicates whether the query succeeded and, if not, how it
-failed.  It may have any of the following values:
-.TP 19
-.B ARES_SUCCESS
-The host lookup completed successfully and 
-.I host
-now points to the result (and must be freed with \fIares_free_hostent(3)\fP).
-.TP 19
-.B ARES_ENOTFOUND
-The hostname
-.I name
-was not found.
-.TP 19
-.B ARES_EFILE
-There was a file I/O error while performing the lookup.
-.TP 19
-.B ARES_ENOMEM
-Memory was exhausted.
-.PP
-On successful completion of the query, the pointer pointed to by
-.I host
-points to a
-.B struct hostent
-containing the address of the host returned by the lookup.  The user must
-free the memory pointed to by
-.IR host
-when finished with it by calling \fIares_free_hostent(3)\fP.  If the lookup did
-not complete successfully, 
-.I host
-will be
-.BR NULL .
-.SH AVAILABILITY
-Added in c-ares 1.5.4

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

-.TH ARES_GETSOCK 3 "22 December 2005"
-.SH NAME
-ares_getsock \- get file descriptors to wait on
-.SH SYNOPSIS
-.nf
-.B #include <ares.h>
-.PP
-.B int ares_getsock(ares_channel \fIchannel\fP, int *\fIsocks\fP, 
-.B int \fInumsocks\fP);
-.fi
-.SH DESCRIPTION
-The
-.B ares_getsock
-function retrieves the set of file descriptors which the calling
-application should wait on for reading and/or writing for the
-processing of name service queries pending on the name service channel
-identified by
-.IR channel .
-File descriptors will be set in the integer array pointed to by
-\fIsocks\fP.
-\fInumsocks\fP is the size of the given array in number of ints.
-
-This function can only return information about up to 16 sockets. If more are
-in use (however unlikely that is), they are simply not reported back.
-.SH RETURN VALUES
-\fBares_getsock\fP returns a bitmask for what actions to wait for on the
-different sockets. The ares.h header file provides these convenience macros to
-extract the information appropriately:
-
-.nf
-#define ARES_GETSOCK_MAXNUM 16 /* ares_getsock() can return info about
-                                  this many sockets */
-#define ARES_GETSOCK_READABLE(bits,num) (bits & (1<< (num)))
-#define ARES_GETSOCK_WRITABLE(bits,num) (bits & (1 << ((num) + \
-                                         ARES_GETSOCK_MAXNUM)))
-.fi
-.SH NOTES
-This function was added in c-ares 1.3.1

-.TH ARES_INIT 3 "26 May 2009"
-.SH NAME
-ares_init, ares_init_options \- Initialize a resolver channel
-.SH SYNOPSIS
-.nf
-.B #include <ares.h>
-.PP
-.B int ares_init(ares_channel *\fIchannelptr\fP)
-.B int ares_init_options(ares_channel *\fIchannelptr\fP,
-.B 	struct ares_options *\fIoptions\fP, int \fIoptmask\fP)
-.PP
-.B cc file.c -lcares
-.fi
-.SH DESCRIPTION
-The \fBares_init\fP function initializes a communications channel for name
-service lookups.  If it returns successfully, \fBares_init\fP will set the
-variable pointed to by \fIchannelptr\fP to a handle used to identify the name
-service channel.  The caller should invoke
-.BR ares_destroy (3)
-on the handle when the channel is no longer needed.
-.PP
-The \fBares_init_options\fP function also initializes a name service channel,
-with additional options useful for applications requiring more control over
-name service configuration. The \fIoptmask\fP parameter specifies which fields
-in the structure pointed to by \fIoptions\fP are set, as follows:
-.TP 18
-.B ARES_OPT_FLAGS
-.B int \fIflags\fP;
-.br
-Flags controlling the behavior of the resolver.  See below for a
-description of possible flag values.
-.TP 18
-.B ARES_OPT_TIMEOUT
-.B int \fItimeout\fP;
-.br
-The number of seconds each name server is given to respond to a query on the
-first try.  (After the first try, the timeout algorithm becomes more
-complicated, but scales linearly with the value of \fItimeout\fP.)  The
-default is five seconds. This option is being deprecated by
-\fIARES_OPT_TIMEOUTMS\fP starting in c-ares 1.5.2.
-.TP 18
-.B ARES_OPT_TIMEOUTMS
-.B int \fItimeout\fP;
-.br
-The number of milliseconds each name server is given to respond to a query on
-the first try.  (After the first try, the timeout algorithm becomes more
-complicated, but scales linearly with the value of \fItimeout\fP.)  The
-default is five seconds. Note that this option is specified with the same
-struct field as the former \fIARES_OPT_TIMEOUT\fP, it is but the option bits
-that tell c-ares how to interpret the number. This option was added in c-ares
-1.5.2.
-.TP 18
-.B ARES_OPT_TRIES
-.B int \fItries\fP;
-.br
-The number of tries the resolver will try contacting each name server
-before giving up.  The default is four tries.
-.TP 18
-.B ARES_OPT_NDOTS
-.B int \fIndots\fP;
-.br
-The number of dots which must be present in a domain name for it to be
-queried for "as is" prior to querying for it with the default domain
-extensions appended.  The default value is 1 unless set otherwise by
-resolv.conf or the RES_OPTIONS environment variable.
-.TP 18
-.B ARES_OPT_PORT
-.B unsigned short \fIport\fP;
-.br
-The port to use for queries (both TCP and UDP), in network byte order.
-The default value is 53 (in network byte order), the standard name
-service port.
-.TP 18
-.B ARES_OPT_SERVERS
-.B struct in_addr *\fIservers\fP;
-.br
-.B int \fInservers\fP;
-.br
-The list of servers to contact, instead of the servers specified in
-resolv.conf or the local named.
-.TP 18
-.B ARES_OPT_DOMAINS
-.B char **\fIdomains\fP;
-.br
-.B int \fIndomains\fP;
-.br
-The domains to search, instead of the domains specified in resolv.conf
-or the domain derived from the kernel hostname variable.
-.TP 18
-.B ARES_OPT_LOOKUPS
-.B char *\fIlookups\fP;
-.br
-The lookups to perform for host queries.  
-.I lookups
-should be set to a string of the characters "b" or "f", where "b"
-indicates a DNS lookup and "f" indicates a lookup in the hosts file.
-.TP 18
-.B ARES_OPT_SOCK_STATE_CB
-.B void (*\fIsock_state_cb\fP)(void *data, int s, int read, int write);
-.br
-.B void *\fIsock_state_cb_data\fP;
-.br
-A callback function to be invoked when a socket changes state.
-.I s
-will be passed the socket whose state has changed;
-.I read
-will be set to true if the socket should listen for read events, and
-.I write
-will be set to true if the socket should listen for write events.
-The value of
-.I sock_state_cb_data
-will be passed as the
-.I data
-argument.
-.PP
-The
-.I flags
-field should be the bitwise or of some subset of the following values:
-.TP 23
-.B ARES_FLAG_USEVC
-Always use TCP queries (the "virtual circuit") instead of UDP
-queries.  Normally, TCP is only used if a UDP query yields a truncated
-result.
-.TP 23
-.B ARES_FLAG_PRIMARY
-Only query the first server in the list of servers to query.
-.TP 23
-.B ARES_FLAG_IGNTC
-If a truncated response to a UDP query is received, do not fall back
-to TCP; simply continue on with the truncated response.
-.TP 23
-.B ARES_FLAG_NORECURSE
-Do not set the "recursion desired" bit on outgoing queries, so that the name
-server being contacted will not try to fetch the answer from other servers if
-it doesn't know the answer locally. Be aware that ares will not do the
-recursion for you.  Recursion must be handled by the application calling ares
-if \fIARES_FLAG_NORECURSE\fP is set.
-.TP 23
-.B ARES_FLAG_STAYOPEN
-Do not close communications sockets when the number of active queries
-drops to zero.
-.TP 23
-.B ARES_FLAG_NOSEARCH
-Do not use the default search domains; only query hostnames as-is or
-as aliases.
-.TP 23
-.B ARES_FLAG_NOALIASES
-Do not honor the HOSTALIASES environment variable, which normally
-specifies a file of hostname translations.
-.TP 23
-.B ARES_FLAG_NOCHECKRESP
-Do not discard responses with the SERVFAIL, NOTIMP, or REFUSED
-response code or responses whose questions don't match the questions
-in the request.  Primarily useful for writing clients which might be
-used to test or debug name servers.
-.SH RETURN VALUES
-.I ares_init
-or
-.I ares_init_options
-can return any of the following values:
-.TP 14
-.B ARES_SUCCESS
-Initialization succeeded.
-.TP 14
-.B ARES_EFILE
-A configuration file could not be read.
-.TP 14
-.B ARES_ENOMEM
-The process's available memory was exhausted.
-.TP 14
-.B ARES_ENOTINITIALIZED
-c-ares library initialization not yet performed.

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

-.SH DESCRIPTION
-.PP
-The
-.B ares_library_init
-function performs initializations internally required by the c-ares
-library that must take place before any other function provided by
-c-ares can be used in a program.
-.PP
-This function must be called one time within the life of a program,
-before the program actually executes any other c-ares library function.
-Initializations done by this function remain effective until a
-call to \fIares_library_cleanup(3)\fP is performed.

-when c-ares is in an uninitialized state is actually effective.

-\fIARES_LIB_INIT_ALL\fP. Don't use any other value unless you are
-familiar with it and trying to control some internal c-ares feature.
-.PP
-.B This function is not thread safe.
-You have to call it once the program has started, but this call must be done
-before the program starts any other thread. This is required to avoid
-potential race conditions in library initialization, and also due to the fact
-that \fIares_library_init(3)\fP might call functions from other libraries that
-are thread unsafe, and could conflict with any other thread that is already
-using these other libraries.
-.PP
-Win32/64 application DLLs shall not call \fIares_library_init(3)\fP from the
-DllMain function. Doing so will produce deadlocks and other problems.
-.SH FLAGS
-.TP 5
-.B ARES_LIB_INIT_ALL
-Initialize everything possible. This sets all known bits.
-.TP
-.B ARES_LIB_INIT_WIN32
-Initialize Win32/64 specific libraries.
-.TP
-.B ARES_LIB_INIT_NONE
-Initialize nothing extra. This sets no bit.
-.SH RETURN VALUE
-Upon successful completion, ares_library_init() will return 0.  Otherwise, a
-non-zero error number will be returned to indicate the error. Except for
-\fIares_strerror(3)\fP, you shall not call any other c-ares function upon
-\fIares_library_init(3)\fP failure.
-.SH AVAILABILITY
-This function was first introduced in c-ares version 1.7.0 along with the
-definition of preprocessor symbol \fICARES_HAVE_ARES_LIBRARY_INIT\fP as an
-indication of the availability of this function.
-.PP
-Since the introduction of this function it is absolutely mandatory to
-call it for any Win32/64 program using c-ares.
-.PP
-Non-Win32/64 systems can still use c-ares version 1.7.0 without calling
-\fIares_library_init(3)\fP due to the fact that \fIcurrently\fP it is nearly
-a do-nothing function on non-Win32/64 platforms at this point.

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

-.TH ARES_PARSE_A_REPLY 3 "25 July 1998"
-.SH NAME
-ares_parse_a_reply \- Parse a reply to a DNS query of type A
-.SH SYNOPSIS
-.nf
-.B #include <ares.h>
-.PP
-.B int ares_parse_a_reply(const unsigned char *\fIabuf\fP, int \fIalen\fP,
-.B 	struct hostent **\fIhost\fP,
-.B      struct ares_addrttl *\fIaddrttls\fB, int *\fInaddrttls\fB);
-.fi
-.SH DESCRIPTION
-The
-.B ares_parse_a_reply
-function parses the response to a query of type A into a
-.BR "struct hostent"
-and/or an array of
-.BR "struct ares_addrttls" . 
-The parameters
-.I abuf
-and
-.I alen
-give the contents of the response.  The result is stored in allocated
-memory and a pointer to it stored into the variable pointed to by
-.IR host ,
-if host is nonnull.
-It is the caller's responsibility to free the resulting host structure
-using
-.BR ares_free_hostent (3)
-when it is no longer needed.
-.PP
-If
-.IR addrttls
-and
-.IR naddrttls
-are both nonnull,
-then up to *naddrttls
-.BR "struct ares_addrttl"
-records are stored in the array pointed to by addrttls,
-and then *naddrttls is set to the number of records so stored.
-Note that the memory for these records is supplied by the caller.
-.SH RETURN VALUES
-.B ares_parse_a_reply
-can return any of the following values:
-.TP 15
-.B ARES_SUCCESS
-The response was successfully parsed.
-.TP 15
-.B ARES_EBADRESP
-The response was malformatted.
-.TP 15
-.B ARES_ENODATA
-The response did not contain an answer to the query.
-.TP 15
-.B ARES_ENOMEM
-Memory was exhausted.
-.SH SEE ALSO
-.BR ares_gethostbyname (3),
-.BR ares_free_hostent (3)

-.SH NAME
-ares_parse_srv_reply \- Parse a reply to a DNS query of type SRV
-.SH SYNOPSIS
-.nf
-.B #include <ares.h>
-.PP
-.B int ares_parse_srv_reply(const unsigned char* \fIabuf\fP, int \fIalen\fP,
-.B                          struct ares_srv_reply** \fIsrv_out\fP);
-.fi
-.SH DESCRIPTION
-The
-.B ares_parse_srv_reply
-function parses the response to a query of type SRV into a
-linked list of
-.I struct ares_srv_reply 
-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 srv_out .
-It is the caller's responsibility to free the resulting
-.IR srv_out
-structure when it is no longer needed using the function
-.B ares_free_data
-.PP
-The structure 
-.I ares_srv_reply
-contains the following fields:
-.sp
-.in +4n
-.nf
-struct ares_srv_reply {
-    struct ares_srv_reply  *next;
-    unsigned short weight;
