Preserve empty line following last target

meter/callback during FTP command/response sequences. It turned out it was
   really lame before and now the progress meter SHOULD get called at least
   once per second.

+# Google Android makefile for curl and libcurl
+#
+# Place the curl source (including this makefile) into external/curl/ in the
+# Android source tree.  Then build them with 'make curl' or just 'make libcurl'
+# from the Android root. Tested with Android 1.5
+#
+# Note: you must first create a curl_config.h file by running configure in the
+# Android environment. The only way I've found to do this is tricky. Perform a
+# normal Android build with libcurl in the source tree, providing the target
+# "showcommands" to make. The build will eventually fail (because curl_config.h
+# doesn't exist yet), but the compiler commands used to build curl will be
+# shown. Now, from the external/curl/ directory, run curl's normal configure
+# command with flags that match what Android itself uses. This will mean
+# putting the compiler directory into the PATH, putting the -I, -isystem and
+# -D options into CPPFLAGS, putting the -m, -f, -O and -nostdlib options into
+# CFLAGS, and putting the -Wl, -L and -l options into LIBS, along with the path
+# to the files libgcc.a, crtbegin_dynamic.o, and ccrtend_android.o. Remember
+# that the paths must be absolute since you will not be running configure from
+# the same directory as the Android make.  The normal cross-compiler options
+# must also be set.
+#
+# The end result will be a configure command that looks something like this
+# (the environment variable A is set to the Android root path):
+#
+#  A=`realpath ../..` && \
+#  PATH="$A/prebuilt/linux-x86/toolchain/arm-eabi-X/bin:$PATH" \

-Daniel (28 December 1999):
- - Tim Verhoeven correctly identified that curl
-   doesn't support URL formatted file names when getting ftp. Now, there's a
-   problem with getting very weird file names off FTP servers. RFC 959 defines
-   that the file name syntax to use should be the same as in the native OS of
-   the server. Since we don't know the peer server system we currently just
-   translate the URL syntax into plain letters. It is still better and with
-   the solaris 2.6-supplied ftp server it works with spaces in the file names.
-
-Daniel (27 December 1999):
- - When curl parsed cookies straight off a remote site, it corrupted the input
-   data, which, if the downloaded headers were stored made very odd characters
-   in the saved data. Correctly identified and reported by Paul Harrington.
-
-Daniel (13 December 1999):
- - General cleanups in the library interface. There had been some bad kludges
-   added during times of stress and I did my best to clean them off. It was
-   both regarding the lib API as well as include file confusions.
-
-Daniel (3 December 1999):
- - A small --stderr bug was reported by Eetu Ojanen...
-
- - who also brought the suggestion of extending the -X flag to ftp list as
-   well. So, now it is and the long option is now --request instead. It is
-   only for ftp list for now (and the former http stuff too of course).
-
-Lars J. Aas (24 November 1999):
- - Patched curl to compile and build under BeOS. Doesn't work yet though!
-
- - Corrected the Makefile.am files to allow putting object files in
-   different directories than the sources.
-
-Version 6.3.1
-
-Daniel (23 November 1999):
- - I've had this major disk crash. My good old trust-worthy source disk died
-   along with the machine that hosted it. Thank goodness most of all the
-   things I've done are either backed up elsewhere or stored in this CVS
-   server!
-
- - Michael S. Steuer pointed out a bug in the -F handling
-   that made curl hang if you posted an empty variable such as '-F name='. It
-   was one of those old bugs that never have worked properly...
-
- - Jason Baietto pointed out a general flaw in the HTTP
-   download. Curl didn't complain if it was prematurely aborted before the
-   entire download was completed. It does now.
-
-Daniel (19 November 1999):
- - Chris Maltby very accurately criticized the lack of
-   return code checks on the fwrite() calls. I did a thorough check for all
-   occurrences and corrected this.
-
-Daniel (17 November 1999):
- - Paul Harrington pointed out that the -m/--max-time option
-   doesn't work for the slow system calls like gethostbyname()... I don't have
-   any good fix yet, just a slightly less bad one that makes curl exit hard
-   when the timeout is reached.
-
- - Bjorn Reese helped me point out a possible problem that might be the reason
-   why Thomas Hurst experience problems in his Amiga version.
-
- Daniel (12 November 1999):
- - I found a crash in the new cookie file parser. It crashed when you gave
-   a plain http header file as input...
-
-Version 6.3
-
- Daniel (10 November 1999):
- - I kind of found out that the HTTP time-conditional GETs (-z) aren't always
-   respected by the web server and the document is therefore sent in whole
-   again, even though it doesn't match the requested condition. After reading
-   section 13.3.4 of RFC 2616, I think I'm doing the right thing now when I do
-   my own check as well. If curl thinks the condition isn't met, the transfer
-   is aborted prematurely (after all the headers have been received).
-
- - After comments from Robert Linden I also rewrote some parts of the man page
-   to better describe how the -F works.
-
- - Michael Anti put up a new curl download mirror in
-   China:  http://www.pshowing.com/curl/
-
- - I added the list of download mirrors to the README file
-
- - I did add more explanations to the man page
-
- Daniel (8 November 1999):
- - I made the -b/--cookie option capable of reading netscape formatted cookie
-   files as well as normal http-header files. It should be able to
-   transparently figure out what kind of file it got as input.
-
- Daniel (29 October 1999):
- - Another one of Sebastiaan van Erk's ideas (that has been requested before
-   but I seem to have forgotten who it was), is to add support for ranges in
-   FTP downloads. As usual, one request is just a request, when they're two
-   it is a demand. I've added simple support for X-Y style fetches. X has to
-   be the lower number, though you may omit one of the numbers. Use the -r/
-   --range switch (previously HTTP-only).
-
- - Sebastiaan van Erk suggested that curl should be
-   able to show the file size of a specified file. I think this is a splendid
-   idea and the -I flag is now working for FTP. It displays the file size in
-   this manner:
-        Content-Length: XXXX
-   As it resembles normal headers, and leaves us the opportunity to add more
-   info in that display if we can come up with more in the future! It also
-   makes sense since if you access ftp through a HTTP proxy, you'd get the
-   file size the same way.
-
-   I changed the order of the QUOTE command executions. They're now executed
-   just after the login and before any other command. I made this to enable
-   quote commands to run before the -I stuff is done too.
-
- - I found out that -D/--dump-header and -V/--version weren't documented in
-   the man page.
-
- - Many HTTP/1.1 servers do not support ranges. Don't ask me why. I did add
-   some text about this in the man page for the range option. The thread in
-   the mailing list that started this was initiated by Michael Anti.
-
- - I get reports about nroff crashes on solaris 2.6+ when displaying the curl
-   man page. Switch to gnroff instead, it is reported to work(!). Adam Barclay
-   reported and brought the suggestion.
-
- - In a dialogue with Johannes G. Kristinsson we came
-   up with the idea to let -H/--header specified headers replace the
-   internally generated headers, if you happened to select to add a header
-   that curl normally uses by itself. The advantage with this is not entirely
-   obvious, but in Johannes' case it means that he can use another Host: than
-   the one curl would set.
-
- Daniel (27 October 1999):
- - Jongki Suwandi brought a nice patch for (yet another) crash when following
-   a location:. This time you had to follow a https:// server's redirect to
-   get the core.
-
-Version 6.2
-
- Daniel (21 October 1999):
- - I think I managed to remove the suspicious (nil) that has been seen just
-   before the "Host:" in HTTP requests when -v was used.
- - I found out that if you followed a location: when using a proxy, without
-   having specified http:// in the URL, the protocol part was added once again
-   when moving to the next URL! (The protocol part has to be added to the
-   URL when going through a proxy since it has no protocol-guessing system
-   such as curl has.)
- - Benjamin Ritcey reported a core dump under solaris 2.6
-   with OpenSSL 0.9.4. It turned out this was due to a bad free() in main.c
-   that occurred after the download was done and completed.
- - Benjamin found ftp downloads to show the first line of the download meter
-   to get written twice, and I removed that problem. It was introduced with
-   the multiple URL support.
- - Dan Zitter correctly pointed out that curl 6.1 and earlier versions didn't
-   honor RFC 2616 chapter 4 section 2, "Message Headers": "...Field names are
-   case-insensitive..."  HTTP header parsing assumed a certain casing. Dan
-   also provided me with a patch that corrected this, which I took the liberty
-   of editing slightly.
- - Dan Zitter also provided a nice patch for config.guess to better recognize
-   the Mac OS X
- - Dan also corrected a minor problem in the lib/Makefile that caused linking
-   to fail on OS X.
-
- Daniel (19 October 1999):
- - Len Marinaccio came up with some problems with curl.  Since Windows has a
-   crippled shell, it can't redirect stderr and that causes trouble. I added
-   --stderr today which allows the user to redirect the stderr stream to a
-   file or stdout.
-
- Daniel (18 October 1999):
- - The configure script now understands the '--without-ssl' flag, which now
-   totally disable SSL/https support. Previously it wasn't possible to force
-   the configure script to leave SSL alone. The previous functionality has
-   been retained. Troy Engel helped test this new one.
-
-Version 6.1
-
- Daniel (17 October 1999):
- - I ifdef'ed or commented all the zlib stuff in the sources and configure
-   script. It turned out we needed to mock more with zlib than I initially
-   thought, to make it capable of downloading compressed HTTP documents and
-   uncompress them on the fly. I didn't mean the zlib parts of curl to become
-   more than minor so this means I halt the zlib expedition for now and wait
-   until someone either writes the code or zlib gets updated and better
-   adjusted for this kind of usage.  I won't get into details here, but a
-   short a summary is suitable:
-   - zlib can't automatically detect whether to use zlib or gzip
-     decompression methods.
-   - zlib is very neat for reading gzipped files from a file descriptor,
-     although not as nice for reading buffer-based data such as we would
-     want it.
-   - there are still some problems with the win32 version when reading from
-     a file descriptor if that is a socket
-
- Daniel (14 October 1999):
- - Moved the (external) include files for libcurl into a subdirectory named
-   curl and adjusted all #include lines to use <curl/XXXX> to maintain a
-   better name space and control of the headers. This has been requested.
-
- Daniel (12 October 1999):
- - I modified the 'maketgz' script to perform a 'make' too before a release
-   archive is put together in an attempt to make the time stamps better and
-   hopefully avoid the double configure-running that use to occur.
-
- Daniel (11 October 1999):
- - Applied J<>rn's patches that fixes zlib for mingw32 compiles as well as
-   some other missing zlib #ifdef and more text on the multiple URL docs in
-   the man page.
-
-Version 6.1beta
-
- Daniel (6 October 1999):
- - Douglas E. Wegscheid sent me a patch that made the exact same thing as I
-   just made: the -d switch is now capable of reading post data from a named
-   file or stdin.  Use it similarly to the -F. To read the post data from a
-   given file:
-
-        curl -d @path/to/filename www.postsite.com
-
-   or let curl read it out from stdin:
-
-        curl -d @- www.postit.com
-
- J<>rn Hartroth (3 October 1999):
- - Brought some more patches for multiple URL functionality. The MIME
-   separation ideas are almost scrapped now, and a custom separator is being
-   used instead. This is still compile-time "flagged".
-
- Daniel
- - Updated curl.1 with multiple URL info.
-
- Daniel (30 September 1999):
- - Felix von Leitner brought openssl-check fixes for configure.in to work
-   out-of-the-box when the openssl files are installed in the system default
-   dirs.
-
- Daniel (28 September 1999)
- - Added libz functionality. This should enable decompressing gzip, compress
-   or deflate encoding HTTP documents. It also makes curl send an accept that
-   it accepts that kind of encoding. Compressed contents usually shortens
-   download time. I *need* someone to tell me a site that uses compressed HTTP
-   documents so that I can test this out properly.
-
- - As a result of the adding of zlib awareness, I changed the version string
-   a little. I plan to add openldap version reporting in there too.
-
- Daniel (17 September 1999)
- - Made the -F option allow stdin when specifying files. By using '-' instead
-   of file name, the data will be read from stdin.
-
-Version 6.0
-
- Daniel (13 September 1999)
- - Added -X/--http-request <request> to enable any HTTP command to be sent.
-   Do not that your server has to support the exact string you enter. This
-   should possibly a string like DELETE or TRACE.
-
- - Applied Douglas' mingw32-fixes for the makefiles.
-
- Daniel (10 September 1999)
- - Douglas E. Wegscheid pointed out a problem. Curl didn't check the FTP
-   servers return code properly after the --quote commands were issued. It
-   took anything non 200 as an error, when all 2XX codes should be accepted as
-   OK.
-
- - Sending cookies to the same site in multiple lines like curl used to do
-   turned out to be bad and breaking the cookie specs. Curl now sends all
-   cookies on a single Cookie: line. Curl is not yet RFC 2109 compliant, but I
-   doubt that many servers do use that syntax (yet).
-
- Daniel (8 September 1999)
- - J<>rn helped me make sure it still compiles nicely with mingw32 under win32.
-
- Daniel (7 September 1999)
- - FTP upload through proxy is now turned into a HTTP PUT. Requested by
-   Stefan Kanthak.
-
- - Added the ldap files to the .m32 makefile.
-
- Daniel (3 September 1999)
- - Made cookie matching work while using HTTP proxy.
-
- Bjorn Reese (31 August 1999)
- - Passed his ldap:// patch. Note that this requires the openldap shared
-   library to be installed and that LD_LIBRARY_PATH points to the
-   directory where the lib will be found when curl is run with a
-   ldap:// URL.
-
- J<>rn Hartroth (31 August 1999)
- - Made the Mingw32 makefiles into single files.
- - Made file:// work for Win32. The same code is now used for unix as well for
-   performance reasons.
-
- Douglas E. Wegscheid (30 August 1999)
- - Patched the Mingw32 makefiles for SSL builds.
-
- Matthew Clarke (30 August 1999)
- - Made a cool patch for configure.in to allow --with-ssl to specify the
-   root dir of the openssl installation, as in
-
-        ./configure --with-ssl=/usr/ssl_here
-
- - Corrected the 'reconf' script to work better with some shells.
-
- J<>rn Hartroth (26 August 1999)
- - Fixed the Mingw32 makefiles in lib/ and corrected the file.c for win32
-   compiles.
-
-Version 5.11
-
- Daniel (25 August 1999)
- - John Weismiller pointed out a bug in the header-line
-   realloc() system in download.c.
-
- - I added lib/file.[ch] to offer a first, simple, file:// support. It
-   probably won't do much good on win32 system at this point, but I see it
-   as a start.
-
- - Made the release archives get a Makefile in the root dir, which can be
-   used to start the compiling/building process easier. I haven't really
-   changed any INSTALL text yet, I wanted to get some feed-back on this
-   first.
-
- Daniel (17 August 1999)
- - Another Location: bug. Curl didn't do proper relative locations if the
-   original URL had cgi-parameters that contained a slash. Nusu's page
-   again.
-
- - Corrected the NO_PROXY usage. It is a list of substrings that if one of
-   them matches the tail of the host name it should connect to, curl should
-   not use a proxy to connect there. Pointed out to me by Douglas
-   E. Wegscheid.  I also changed the README text a little regarding this.
-
- Daniel (16 August 1999)
- - Fixed a memory bug with http-servers that sent Location: to a Location:
-   page. Nusu's page showed this too.
-
- - Made cookies work a lot better. Setting the same cookie name several times
-   used to add more cookies instead of replacing the former one which it
-   should've. Nusu <nus at intergorj.ro> brought me an URL that made this
-   painfully visible...
-
- Troy (15 August 1999)
- - Brought new .spec files as well as a patch for configure.in that lets the
-   configure script find the openssl files better, even when the include
-   files are in /usr/include/openssl
-
-Version 5.10
-
- Daniel (13 August 1999)
- - SSL_CTX_set_default_passwd_cb() has been modified in the 0.9.4 version of
-   OpenSSL. Now why couldn't they simply add a *new* function instead of
-   modifying the parameters of an already existing function? This way, we get
-   a compiler warning if compiling with 0.9.4 but not with earlier. So, I had
-   to come up with a #if construction that deals with this...
-
- - Made curl output the SSL version number get displayed properly with 0.9.4.
-
- Troy (12 August 1999)
- - Added MingW32 (GCC-2.95) support under Win32. The INSTALL file was also
-   a bit rearranged.
- 
- Daniel (12 August 1999)
- - I had to copy a good <arpa/telnet.h> include file into the curl source
-   tree to enable the silly win32 systems to compile. The distribution rights
-   allows us to do that as long as the file remains unmodified.
-
- - I corrected a few minor things that made the compiler complain when
-   -Wall -pedantic was used.
-
- - I'm moving the official curl web page to http://curl.haxx.nu. I think it
-   will make it easier to remember as it is a lot shorter and less cryptic.
-   The old one still works and shows the same info.
-
- Daniel (11 August 1999)
- - Albert Chin-A-Young mailed me another correction for NROFF in the
-   configure.in that is supposed to be better for IRIX users.
-
- Daniel (10 August 1999)
- - Albert Chin-A-Young helped me with some stupid Makefile things, as well as
-   some fiddling with the getdate.c stuff that he had problems with under
-   HP-UX v10. getdate.y will now be compiled into getdate.c if the appropriate
-   yacc or bison is found by the configure script. Since this is slightly new,
-   we need to test the output getdate.c with win32 systems to make sure it
-   still compiles there.
-
- Daniel (5 August 1999)
- - I've just setup a new mailing list with the intention to keep discussions
-   around libcurl development in it. I mainly expect it to be for thoughts and
-   brainstorming around a "next generation" library, rather than nitpicking
-   about the current implementation or details in the current libcurl.
-
-   To join our happy bunch of future-looking geeks, enter 'subscribe
-   <address>' in the body of a mail and send it to
-   libcurl-request@listserv.fts.frontec.se.  Curl bug reports, the usual curl
-   talk and everything else should still be kept in this mailing list. I've
-   started to archive this mailing list and have put the libcurl web page at
-   www.fts.frontec.se/~dast/libcurl/.
-
- - Stefan Kanthak contacted me regarding a few problems in the configure
-   script which he discovered when trying to make curl compile and build under
-   Siemens SINIX-Z V5.42B2004!
-
- - Marcus Klein very accurately informed me that src/version.h was not present
-   in the CVS repository. Oh, how silly...
-
- - Linus Nielsen rewrote the telnet:// part and now curl offers limited telnet
-   support. If you run curl like 'curl telnet://host' you'll get all output on
-   the screen and curl will read input from stdin. You'll be able to login and
-   run commands etc, but since the output is buffered, expect to get a little
-   weird output.
-
-   This is still in its infancy and it might get changed. We need your
-   feed-back and input in how this is best done.
-
-   WIN32 NOTE: I bet we'll get problems when trying to compile the current
-   lib/telnet.c on win32, but I think we can sort them out in time.
-
- - David Sanderson reported that FORCE_ALLOCA_H or HAVE_ALLOCA_H must be
-   defined for getdate.c to compile properly on HP-UX 11.0. I updated the
-   configure script to check for alloca.h which should make it.
-
- Daniel (4 August 1999)
- - I finally got to understand Marcus Klein's ftp download resume problem,
-   which turns out to be due to different outputs from different ftp
-   servers. It makes ftp download resuming a little trickier, but I've made
-   some modifications I really believe will work for most ftp servers and I do
-   hope you report if you have problems with this!
-
- - Added text about file transfer resuming to README.curl.
-
- Daniel (2 August 1999)
- - Applied a progress-bar patch from Lars J. Aas. It offers
-   a new styled progress bar enabled with -#/--progress-bar. 
-
- T. Yamada <tai at imasy.or.jp> (30 July 1999)
- - It breaks with segfault when 1) curl is using .netrc to obtain
-   username/password (option '-n'), and 2) is automatically redirected to
-   another location (option '-L').
-
-   There is a small bug in lib/url.c (block starting from line 641), which
-   tries to take out username/password from user- supplied command-line
-   argument ('-u' option). This block is never executed on first attempt since
-   CONF_USERPWD bit isn't set at first, but curl later turns it on when it
-   checks for CONF_NETRC bit. So when curl tries to redo everything due to
-   redirection, it segfaults trying to access *data->userpwd.
-
-Version 5.9.1
-
- Daniel (30 July 1999)
- - Steve Walch pointed out that there is a memory leak in the formdata
-   functions. I added a FormFree() function that is now used and supposed to
-   correct this flaw.
-
- - Mark Wotton reported:
-   'curl -L https://www.cwa.com.au/' core dumps.  I managed to cure this by
-   correcting the cleanup procedure. The bug seems to be gone with my OpenSSL
-   0.9.2b, although still occurs when I run the ~100 years old SSLeay 0.8.0. I
-   don't know whether it is curl or SSLeay that is to blame for that.
-
- - Marcus Klein:
-   Reported an FTP upload resume bug that I really can't repeat nor understand.
-   I leave it here so that it won't be forgotten.
-
- Daniel (29 July 1999)
- - Costya Shulyupin suggested support for longer URLs when following Location:
-   and I could only agree and fix it!
-
- - Leigh Purdie found a problem in the upload/POST department. It turned out
-   that http.c accidentaly cleared the pointer instead of the byte counter
-   when supposed to.
-
- - Costya Shulyupin pointed out a problem with port numbers and Location:. If
-   you had a server at a non-standard port that redirected to an URL using a
-   standard port number, curl still used that first port number.
-
- - Ralph Beckmann pointed out a problem when using both CONF_FOLLOWLOCATION
-   and CONF_FAILONERROR simultaneously. Since the CONF_FAILONERROR exits on
-   the 302-code that the follow location header outputs it will never show any
-   html on location: pages. I have now made it look for >=400 codes if
-   CONF_FOLLOWLOCATION is set.
-
- - 'struct slist' is now renamed to 'struct curl_slist' (as suggested by Ralph
-   Beckmann).
-
- - Joshua Swink and Rick Welykochy were the first to point out to me that the
-   latest OpenSSL package now have moved the standard include path. It is now
-   in /usr/local/ssl/include/openssl and I have now modified the --enable-ssl
-   option for the configure script to use that as the primary path, and I
-   leave the former path too to work with older packages of OpenSSL too.
-
- Daniel (9 June 1999)
- - I finally understood the IRIX problem and now it seem to compile on it!
-   I am gonna remove those #define strcasecmp() things once and for all now.
-
- Daniel (4 June 1999)
- - I adjusted the FTP reply 227 parser to make the PASV command work better
-   with more ftp servers. Appearantly the Roxen Challanger server replied
-   something curl 5.9 could deal with! :-( Reported by Ashley Reid-Montanaro
-   and Mark Butler brought a solution for it.
-
- Daniel (26 May 1999)
- - Rearranged. README is new, the old one is now README.curl and I added a
-   README.libcurl with text I got from Ralph Beckmann.
-
- - I also updated the INSTALL text.
-
- Daniel (25 May 1999)
- - David Jonathan Lowsky correctly pointed out that curl didn't properly deal
-   with form posting where the variable shouldn't have any content, as in curl
-   -F "form=" www.site.com. It was now fixed.
-
-Version 5.9
-
- Daniel (22 May 1999)
- - I've got a bug report from Aaron Scarisbrick in which he states he has some
-   problems with -L under FreeBSD 3.0. I have previously got another bug
-   report from Stefan Grether which points at an error with similar sympthoms
-   when using win32. I made the allocation of the new url string a bit faster
-   and different, don't know if it actually improves anything though...
-
- Daniel (20 May 1999)
- - Made the cookie parser deal with CRLF newlines too.
-
- Daniel (19 May 1999)
- - Download() didn't properly deal with failing return codes from the sread()
-   function. Adam Coyne found the problem in the win32 version, and Troy Engel
-   helped me out isolating it.
-
- Daniel (16 May 1999)
- - Richard Adams pointed out a bug I introduced in 5.8. --dump-header doesn't
-   work anymore! :-/ I fixed it now.
-
- - After a suggestion by Joshua Swink I added -S / --show-error to force curl
-   to display the error message in case of an error, even if -s/--silent was
-   used.
-
- Daniel (10 May 1999)
- - I moved the stuff concerning HTTP, DICT and TELNET it their own source
-   files now. It is a beginning on my clean-up of the sources to make them
-   layer all those protocols better to enable more to be added easier in the
-   future!
-
- - Leon Breedt sent me some files I've not put into the main curl
-   archive. They're for creating the Debian package thingie. He also sent me a
-   debian package that I've made available for download at the web page
-
- Daniel (9 May 1999)
- - Made it compile on cygwin too.
-
- Troy Engel (7 May 1999)
- - Brought a series of patches to allow curl to compile smoothly on MSVC++ 6
-   again!
-
- Daniel (6 May 1999)
- - I changed the #ifdef HAVE_STRFTIME placement for the -z code so that it
-   will be easier to discover systems that don't have that function and thus
-   can't use -z successfully. Made the strftime() get used if WIN32 is defined
-   too.
-
-Version 5.8
-
- Daniel (5 May 1999)
- - I've had it with this autoconf/automake mess. It seems to work allright
-   for most people who don't have automake installed, but for those who have
-   there are problems all over.
-
-   I've got like five different bug reports on this only the last
-   week... Claudio Neves and Federico Bianchi and root <duggerj001 at
-   hawaii.rr.com> are some of them reporting this.
-
-   Currently, I have no really good fix since I want to use automake myself to
-   generate the Makefile.in files. I've found out that the @SHELL@-problems
-   can often be fixed by manually invoking 'automake' in the archive root
-   before you run ./configure... I've hacked my maketgz script now to fiddle
-   a bit with this and my tests seem to work better than before at least!
-
- Daniel (4 May 1999)
- - mkhelp.pl has been doing badly lately. I corrected a case problem in
-   the regexes.
-
- - I've now remade the -o option to not touch the file unless it needs to.
-   I had to do this to make -z option really fine, since now you can make a
-   curl fetch and use a local copy's time when downloading to that file, as
-   in:
-
-        curl -z dump -o dump remote.site.com/file.html
-
-   This will only get the file if the remote one is newer than the local.
-   I'm aware that this alters previous behaviour a little. Some scripts out
-   there may depend on that the file is always touched...
-
- - Corrected a bug in the SSLv2/v3 selection.
-
- - Felix von Leitner requested that curl should be able to send
-   "If-Modified-Since" headers, which indeed is a fair idea.  I implemented it
-   right away! Try -z <expression> where expression is a full GNU date
-   expression or a file name to get the date from!
-
- Stephan Lagerholm (30 Apr 1999)
- - Pointed out a problem with the src/Makefile for FreeBSD. The RM variable
-   isn't set and causes the make to fail.
-
- Daniel (26 April 1999)
- - Am I silly or what? Irving Wolfe pointed out to me that the curl version
-   number was not set properly. Hasn't been since 5.6. This was due to a bug
-   in my maketgz script!
-
- David Eriksson (25 Apr 1999)
- - Found a bug in cookies.c that made it crash at times.
-
-Version 5.7.1
-
- Doug Kaufman (23 Apr 1999)
- - Brought two sunos 4 fixes. One of them being the hostip.c fix mentioned
-   below and the other one a correction in include/stdcheaders.h
-
- - Added a paragraph about compiling with the US-version of openssl to the
-   INSTALL file.
-
- Daniel
- - New mailing list address. Info updated on the web page as well as in the
-   README file
-
- Greg Onufer (20 Apr 1999)
- - hostip.c didn't compile properly on SunOS 5.5.1.
-   It needs an #include <sys/types.h>
-
-Version 5.7
-
- Daniel (Apr 20 1999)
- - Decided to upload a non-beta version right now!
-
- - Made curl support any-length HTTP headers. The destination buffer is now
-   simply enlarged every time it turns out to be too small!
-
- - Added the FAQ file to the archive. Still a bit smallish, but it is a
-   start.
-
- Eric Thelin (15 Apr 1999)
- - Made -D accept '-' instead of filename to write to stdout.
-
-Version 5.6.3beta
-
- Daniel (Apr 12 1999)
-
- - Changed two #ifdef WIN32 to better #ifdef <errorcode> when connect()ing
-   in url.c and ftp.c. Makes cygwin32 deal with them better too. We should
-   try to get some decent win32-replacement there. Anyone?
-
- - The old -3/--crlf option is now ONLY --crlf!
-
- - I changed the "SSL fix" to a more lame one, but that doesn't remove as
-   much functionality. Now I've enabled the lib to select what SSL version it
-   should try first. Appearantly some older SSL-servers don't like when you
-   talk v3 with them so you need to be able to force curl to talk v2 from the
-   start. The fix dated April 6 and posted on the mailing list forced curl to
-   use v2 at all times using a modern OpenSSL version, but we don't really
-   want such a crippled solution.
- 
- - Marc Boucher sent me a patch that corrected a math error for the
-   "Curr.Speed" progress meter.
-
- - Eric Thelin sent me a patch that enables '-K -' to read a config file from
-   stdin.
-
- - I found out we didn't close the file properly before so I added it!
-
- Daniel (Apr 9 1999)
- - Yu Xin pointed out a problem with ftp download resume.  It didn't work at
-   all! ;-O
-
- Daniel (Apr 6 1999)
- - Corrected the version string part generated for the SSL version.
-
- - I found a way to make some other SSL page work with openssl 0.9.1+ that
-   previously didn't (ssleay 0.8.0 works with it though!). Trying to get
-   some real info from the OpenSSL guys to see how I should do to behave the
-   best way. SSLeay 0.8.0 shouldn't be that much in use anyway these days!
-
-Version 5.6.2beta
-
- Daniel (Apr 4 1999)
- - Finally have curl more cookie "aware". Now read carefully. This is how
-   it works.
-   To make curl read cookies from an already existing file, in plain header-
-   format (like from the headers of a previous fetch) invoke curl with the
-   -b flag like:
-
-        curl -b file http://site/foo.html
-
-   Curl will then use all cookies it finds matching. The old style that sets
-   a single cookie with -b is still supported and is used if the string
-   following -b includes a '=' letter, as in "-b name=daniel".
-
-   To make curl read the cookies sent in combination with a location: (which
-   sites often do) point curl to read a non-existing file at first (i.e
-   to start with no existing cookies), like:
-
-        curl -b nowhere http://site/setcookieandrelocate.html
-
- - Added a paragraph in the TODO file about the SSL problems recently
-   reported. Evidently, some kind of SSL-problem curl may need to address.
-
- - Better "Location:" following.
-
- Douglas E. Wegscheid (Tue, 30 Mar 1999)
- - A subsecond display patch.
-
- Daniel (Mar 14 1999)
- - I've separated the version number of libcurl and curl now. To make
-   things a little easier, I decided to start the curl numbering from
-   5.6 and the former version number known as "curl" is now the one
-   set for libcurl.
-
- - Removed the 'enable-no-pass' from configure, I doubt anyone wanted
-   that.
-
- - Made lots of tiny adjustments to compile smoothly with cygwin under
-   win32. It's a killer for porting this to win32, bye bye VC++! ;-)
-   Compiles and builds out-of-the-box now. See the new wordings in
-   INSTALL for details.
-
- - Beginning experiments with downloading multiple document from a http
-   server while remaining connected.
-
-Version 5.6beta
-
- Daniel (Mar 13 1999)
- - Since I've changed so much, I thought I'd just go ahead and implement the
-   suggestion from Douglas E. Wegscheid. -D or --dump-header is now storing
-   HTTP headers separately in the specified file.
-
- - Added new text to INSTALL on what to do to build this on win32 now.
-
- - Aaargh. I had to take a step back and prefix the shared #include files
-   in the sources with "../include/" to please VC++...
-
- Daniel (Mar 12 1999)
- - Split the url.c source into many tiny sources for better readability
-   and smaller size.
-
- Daniel (Mar 11 1999)
- - Started to change stuff for a move to make libcurl and a more separate
-   curl application that uses the libcurl. Made the libcurl sources into
-   the new lib directory while the curl application will remain in src as
-   before. New makefiles, adjusted configure script and so.
-
-   libcurl.a built quickly and easily. I better make a better interface to
-   the lib functions though.
-
-   The new root dir include/ is supposed to contain the public information
-   about the new libcurl. It is a little ugly so far :-)
-
-
- Daniel (Mar 1 1999)
- - Todd Kaufmann sent me a good link to Netscape's cookie spec as well as the
-   info that RFC 2109 specifies how to use them.  The link is now in the
-   README and the RFC in the RESOURCES.
-
- Daniel (Feb 23 1999)
- - Finally made configure accept --with-ssl to look for SSL libs and includes
-   in the "standard" place /usr/local/ssl...
-
- Daniel (Feb 22 1999)
- - Verified that curl linked fine with OpenSSL 0.9.1c which seems to be
-   the most recent.
-
- Henri Gomez (Fri Feb  5 1999)
- - Sent in an updated curl-ssl.spec. I still miss the script that builds an
-   RPM automatically...
-
-Version 5.5.1
-
- Mark Butler (27 Jan 1999)
- - Corrected problems in Download().
-
- Danitel Stenberg (25 Jan 1999)
- - Jeremie Petit pointed out a few flaws in the source that prevented it from
-   compile warning free with the native compiler under Digital Unix v4.0d.
-
-Version 5.5
-
- Daniel Stenberg (15 Jan 1999)
- - Added Bjorns small text to the README about the DICT protocol.
-
- Daniel Stenberg (11 Jan 1999)
- - <jswink at softcom.net> reported about the win32-versioin: "Doesn't use
-   ALL_PROXY environment variable". Turned out to be because of the static-
-   buffer nature of the win32 environment variable calls!
-
- Bjorn Reese (10 Jan 1999)
- - I have attached a simple addition for the DICT protocol (RFC 2229).
-   It performs dictionary lookups. The output still needs to be better
-   formatted.
-
-   To test it try (the exact format, and more examples are described in
-   the RFC)
-
-        dict://dict.org/m:hello
-        dict://dict.org/m:hello::soundex
-
-
- Vicente Garcia (10 Jan 1999)
- - Corrected the progress meter for files larger than 20MB.
-
- Daniel Stenberg (7 Jan 1999)
- - Corrected the -t and -T help texts. They claimed to be FTP only.
-
-Version 5.4
-
- Daniel Stenberg
- (7 Jan 1999)
- - Irving Wolfe reported that curl -s didn't always supress the progress
-   reporting. It was the form post that autoamtically always switched it on
-   again. This is now corrected!
-
- (4 Jan 1999)
- - Andreas Kostyrka suggested I'd add PUT and he helped me out to test it. If
-   you use -t or -T now on a http or https server, PUT will be used for file
-   upload.
-
-   I removed the former use of -T with HTTP. I doubt anyone ever really used
-   that.
-
- (4 Jan 1999)
- - Erik Jacobsen found a width bug in the mprintf() function.  I corrected it
-   now.
-
- (4 Jan 1999)
- - As John V. Chow pointed out to me, curl accepted very limited URL sizes. It
-   should now accept path parts that are up to at least 4096 bytes.
-
- - Somehow I screwed up when applying the AIX fix from Gilbert Ramirez, so
-   I redid that now.

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

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

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

+                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.
+
+
+Have Fun!

ares/RELEASE-NOTES

@@ -0,0 +1,36 @@
+This is what's new and changed in the c-ares 1.7.0 release:
+
+Changed:
+
+ o in6_addr is not used in ares.h anymore, but a private ares_in6_addr is
+   instead declared and used
+ o ares_gethostbyname() now supports 'AF_UNSPEC' as a family for resolving
+   either AF_INET6 or AF_INET
+ o a build-time configured ares_socklen_t is now used instead of socklen_t
+ o new ares_library_init() and ares_library_cleanup() functions
+ o new --enable-curldebug configure option
+ o ARES_ECANCELLED is now sent as reason for ares_cancel()
+ o added ares_parse_srv_reply()
+ o added ares_parse_txt_reply()
+ o added ares_free_data()
+ o new --enable-symbol-hiding configure option
+ o new Makefile.msvc for any MSVC compiler or MS Visual Studio version
+ o addrttl and addr6ttl structs renamed to ares_addrttl and ares_addr6ttl
+ o naming convention for libraries built with MSVC, see README.msvc
+
+Fixed:
+
+ o ares_parse_*_reply() functions now return ARES_EBADRESP instead of
+   ARES_EBADNAME if the name in the response failed to decode
+ o only expose/export symbols starting with 'ares_'
+ o fix \Device\TCP handle leaks triggered by buggy iphlpapi.dll
+ o init without internet gone no longer fails
+ o out of bounds memory overwrite triggered with malformed /etc/hosts file
+ o function prototypes in man pages out of sync with ares.h

+
+ares_gethostbyname
+
+- When built to support IPv6, it needs to also support PF_UNSPEC or similar,
+  so that an application can ask for any protocol and then c-ares would return
+  all known resolves and not just explicitly IPv4 _or_ IPv6 resolves.
+
+ares_process
+
+- Upon next ABI breakage ares_process() should be changed to return 'int'
+  and return ARES_ENOTINITIALIZED if ares_library_init() has not been called.
+
+ares_process_fd
+
+- Upon next ABI breakage ares_process_fd() should be changed to return
+  'int' and return ARES_ENOTINITIALIZED if library has not been initialized.

+.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 .

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

+.SH SYNOPSIS

+.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.

+ * expanded name; the goal is to tell the caller how many bytes to

+ *
+ * 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

+ * 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.
+ *

+.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.

+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

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

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

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

+.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)))

+.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.

+.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.
+.PP
+Successive calls to this function do nothing, only the first call done
+when c-ares is in an uninitialized state is actually effective.
+.PP
+The
+.I flags
+parameter is a bit pattern that tells c-ares exactly which features
+should be initialized, as described below. Set the desired bits by
+ORing the values together. In normal operation you should specify
+\fIARES_LIB_INIT_ALL\fP. Don't use any other value unless you are
+familiar with it and trying to control some internal c-ares feature.
+.PP
+.B This function is not thread safe.
+You have to call it once the program has started, but this call must be done
+before the program starts any other thread. This is required to avoid
+potential race conditions in library initialization, and also due to the fact
+that \fIares_library_init(3)\fP might call functions from other libraries that
+are thread unsafe, and could conflict with any other thread that is already
+using these other libraries.
+.PP
+Win32/64 application DLLs shall not call \fIares_library_init(3)\fP from the
+DllMain function. Doing so will produce deadlocks and other problems.
+.SH FLAGS
+.TP 5
+.B ARES_LIB_INIT_ALL
+Initialize everything possible. This sets all known bits.
+.TP
+.B ARES_LIB_INIT_WIN32
+Initialize Win32/64 specific libraries.
+.TP
+.B ARES_LIB_INIT_NONE
+Initialize nothing extra. This sets no bit.
+.SH RETURN VALUE
+Upon successful completion, ares_library_init() will return 0.  Otherwise, a
+non-zero error number will be returned to indicate the error. Except for
+\fIares_strerror(3)\fP, you shall not call any other c-ares function upon

+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.
