CHANGES.1999

+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 Jörn'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
+
+ Jörn 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)
+ - Jörn 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.
+
+ Jörn 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.
+
+ Jörn 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.

+  Changelog for the c-ares project
+
+* June 10
+- Gisle Vanem's init patch for Windows:
+
+  The init_by_resolv_conf() function fetches the DNS-server(s)
+  from a series of registry branches.
+
+  This can be wrong in the case where DHCP has assigned nameservers, but the
+  user has overridden these servers with other prefered settings. Then it's
+  wrong to use the DHCPNAMESERVER setting in registry.
+
+  In the case of no global DHCP-assigned or fixed servers, but DNS server(s)
+  per adapter, one has to query the adapter branches.  But how can c-ares know
+  which adapter is valid for use? AFAICS it can't. There could be one adapter
+  that is down (e.g. a VPN adapter).
+
+  So it's better to leave this to the IP Helper API (iphlapi) available in
+  Win-98/2000 and later. My patch falls-back to the old way if not available.
+
+* June 8
+- James Bursa fixed an init issue for RISC OS.
+
+* May 11
+- Nico Stappenbelt reported that when processing domain and search lines in
+  the resolv.conf file, the first entry encountered is processed and used as
+  the search list. According to the manual pages for both Linux, Solaris and
+  Tru64, the last entry of either a domain or a search field is used.
+
+  This is now adjusted in the code
+
+Version 1.2.0 (April 13, 2004)
+
+* April 2, 2004
+- Updated various man pages to look nicer when converted to HTML on the web
+  site.
+
+* April 1, 2004
+- Dirk Manske provided a new function that is now named ares_cancel(). It is
+  used to cancel/cleanup a resolve/request made using ares functions on the
+  given ares channel. It does not destroy/kill the ares channel itself.
+
+- Dominick Meglio cleaned up the formatting in several man pages.
+
+* March 30, 2004
+- Dominick Meglio's new ares_expand_string. A helper function when decoding
+  incoming DNS packages.
+
+- Daniel Stenberg modified the Makefile.in to use a for loop for the man page
+  installation to improve overview and make it easier to add man pages.
+
+Version 1.1.0 (March 11, 2004)
+
+* March 9, 2004
+- Gisle Vanem improved build on Windows.
+
+* February 25, 2004
+- Dan Fandrich found a flaw in the Feb 22 fix.
+
+- Added better configure --enable-debug logic (taken from the curl configure
+  script). Added acinclude.m4 to the tarball.
+
+* February 23, 2004
+- Removed ares_free_errmem(), the function, the file and the man page. It was
+  not used and it did nothing.
+
+- Fixed a lot of code that wasn't "64bit clean" and thus caused a lot of
+  compiler warnings on picky compilers.
+
+* February 22, 2004
+- Dominick Meglio made ares init support multiple name servers in the
+  NameServer key on Windows.
+
+* February 16, 2004
+- Modified ares_private.h to include libcurl's memory debug header if
+  CURLDEBUG is set. This makes all the ares-functions supervised properly by
+  the curl test suite. This also forced me to add inclusion of the
+  ares_private.h header in a few more files that are using some kind of
+  memory-related resources.
+
+- Made the makefile only build ahost and adig if 'make demos' is used.
+
+* February 10, 2004
+- Dirk Manske made ares_version.h installed with 'make install'
+
+* February 4, 2004
+- ares_free_errmem() is subject for removal, it is simply present for future
+  purposes, and since we removed the extra parameter in strerror() it won't
+  be used by c-ares!
+- configure --enable-debug now enables picky compiler options if gcc is used
+- fixed several compiler warnings --enable-debug showed and Joerg Mueller-Tolk
+  reported
+
+Version 1.0.0 (February 3, 2004)
+
+* February 3, 2004
+- now we produce the libcares.a library instead of the previous libares.a
+  since we are no longer compatible
+
+* February 2, 2004
+
+- ares_strerror() has one argument less. This is the first official
+  modification of the existing provided ares API.
+
+* January 29, 2004
+
+- Dirk Manske fixed how the socket is set non-blocking.
+
+* January 4, 2004
+
+- Dominick Meglio made the private gettimeofday() become ares_gettimeofday()
+  instead in order to not pollute the name space and risk colliding with
+  other libraries' versions of this function.
+
+* October 24, 2003. Daniel Stenberg
+
+  Added ares_version().
+
+Version 1.0-pre1 (8 October 2003)
+
+- James Bursa made it run on RISC OS
+
+- Dominick Meglio made it run fine on NT4
+
+- Duncan Wilcox made it work fine on Mac OS X
+
+- Daniel Stenberg adjusted the windows port
+
+- liren at vivisimo.com made the initial windows port
+
+* Imported the sources from ares 1.1.1

+* 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

+* A few of the ares_dns.h macros are fixed to use the proper bitwise

+* Fixed a couple of fenceposts fixed in ares_expand_name()'s

+* In process_timeouts(), extract query->next before calling
+  next_server() and possibly freeing the query structure.
+* Casted arguments to ctype macros casted to unsigned char, since not
+  all char values are valid inputs to those macros according to ANSI.

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

+c-ares
+======
+
+This package is based on ares 1.1.1 (written by Greg Hudson). I decided to
+fork and release a separate project since the ares author didn't want the
+improvements that were vital for our use of it.
+
+This package is dubbed 'c-ares' since I (Daniel Stenberg) wanted this for use
+within the curl project (hence the letter C) and it makes a nice pun. Also,
+c-ares is not API compatible with ares: a new name makes that more obvious to
+the public.
+
+The full source code is available in the 'c-ares' release archives, and in the
+'ares' subdir of the curl CVS source repostitory.
+
+If you find bugs, correct flaws, have questions or have comments in general in
+regard to c-ares (or by all means the original ares too), get in touch with us
+on the c-ares mailing list: http://cool.haxx.se/mailman/listinfo/c-ares
+
+c-ares is of course distributed under the same MIT-style license as the
+original ares.
+
+You'll find all c-ares details and news here:

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

+.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
+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

+.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	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
+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_init, ares_init_options \- Initialize a resolver channel
+.SH SYNOPSIS
+.nf
+.B #include <ares.h>
+.PP
+.B int ares_init(ares_channel *\fIchannel\fP)
+.B int ares_init_options(ares_channel *\fIchannel\fP,
+.B 	struct ares_options *\fIoptions\fP, int \fIoptmask\fP)
+.PP
+.B cc file.c -lares
+.fi
+.SH DESCRIPTION
+The
+.B ares_init
+function initializes a communications channel for name service
+lookups.  If it returns successfully,
+.B ares_init
+will set the variable pointed to by
+.I channel
+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
+.B ares_init_options
+function also initializes a name service channel, with additional
+options useful for applications requiring more control over name
+service configuration.  The
+.I optmask
+parameter specifies which fields in the structure pointed to by
+.I options
+are set, as follows:
+.PP
+.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.
+.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.
+.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.
+.TP 23
+.B ARES_FLAG_STAYOPEN
+Do not close communciations sockets when the number of active queries
+drops to zero.
+.TP 23
+.B ARES_FLAG_NOSEARCH
+Do not use the default search domains; only query hostnames as-is or
+as aliases.
+.TP 23
+.B ARES_FLAG_NOALIASES
+Do not honor the HOSTALIASES environment variable, which normally
+specifies a file of hostname translations.

+.TH ARES_MKQUERY 3 "4 January 2000"
+.SH NAME
+ares_mkquery \- Compose a single-question DNS query buffer
+.SH SYNOPSIS
+.nf
+.B #include <ares.h>
+.PP
+.B int ares_mkquery(const char *\fIname\fP, int \fIdnsclass\fP, int \fItype\fP,
+.B	unsigned short \fIid\fP, int \fIrd\fP, char **\fIbuf\fP,
+.B	int *\fIbuflen\fP)
+.fi
+.SH DESCRIPTION
+The
+.B ares_mkquery
+function composes a DNS query with a single question.
+The parameter
+.I name
+gives the query name as a NUL-terminated C string of period-separated
+labels optionally ending with a period; periods and backslashes within
+a label must be escaped with a backlash.  The parameters
+.I dnsclass
+and
+.I type
+give the class and type of the query using the values defined in
+.BR <arpa/nameser.h> .
+The parameter
+.I id
+gives a 16-bit identifier for the query.  The parameter
+.I rd
+should be nonzero if recursion is desired, zero if not.  The query
+will be placed in an allocated buffer, a pointer to which will be
+stored in the variable pointed to by
+.IR buf ,
+and the length of which will be stored in the variable pointed to by
+.IR buflen .
+It is the caller's responsibility to free this buffer using
+\fIares_free_string(3)\fP when it is no longer needed.
+.SH RETURN VALUES
+.B ares_mkquery
+can return any of the following values:
+.TP 15
+.B ARES_SUCCESS
+Construction of the DNS query succeeded.
+.TP 15
+.B ARES_EBADNAME
+The query name
+.I name
+could not be encoded as a domain name, either because it contained a
+zero-length label or because it contained a label of more than 63
+characters.
+.TP 15
+.B ARES_ENOMEM
+Memory was exhausted.
+.SH SEE ALSO
+.BR ares_expand_name (3),
+.BR ares_free_string (3)

+.TH ARES_PARSE_PTR_REPLY 3 "25 July 1998"
+.SH NAME
+ares_parse_ptr_reply \- Parse a reply to a DNS query of type PTR into a hostent
+.SH SYNOPSIS
+.nf
+.B #include <ares.h>
+.PP
+.B int ares_parse_ptr_reply(const unsigned char *\fIabuf\fP, int \fIalen\fP,
+.B 	const void *\fIaddr\fP, int \fIaddrlen\fP, int \fIfamily\fP,
+.B	struct hostent **\fIhost\fP);
+.fi
+.SH DESCRIPTION
+The
+.B ares_parse_ptr_reply
+function parses the response to a query of type PTR into a
+.BR "struct hostent" .
+The parameters
+.I abuf
+and
+.I alen
+give the contents of the response.  The parameters
+.IR addr ,
+.IR addrlen ,
+and
+.I family
+specify which address was queried for; they are not used to verify the
+response, merely used to fill in the address of the
+.BR "struct hostent" .
+The resulting
+.B struct hostent
+is stored in allocated memory and a pointer to it stored into the
+variable pointed to by
+.IR host .
+It is the caller's responsibility to free the resulting host structure
+using
+.BR ares_free_hostent (3)
+when it is no longer needed.
+.SH RETURN VALUES
+.B ares_parse_ptr_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_gethostbyaddr (3),
+.BR ares_free_hostent (3)

+.TH ARES_PROCESS 3 "25 July 1998"
+.SH NAME
+ares_process \- Process events for name resolution
+.SH SYNOPSIS
+.nf
+.B #include <ares.h>
+.PP
+.B void ares_process(ares_channel \fIchannel\fP, fd_set *\fIread_fds\fP,
+.B	fd_set *\fIwrite_fds\fP)
+.fi
+.SH DESCRIPTION
+The
+.B ares_process
+function handles input/output events and timeouts associated with
+queries pending on the name service channel identified by
+.IR channel .
+The file descriptor sets pointed to by
+.I read_fds
+and
+.I write_fds
+should have file descriptors set in them according to whether the file
+descriptors specified by \fIares_fds(3)\fP are ready for reading and writing.
+(The easiest way to determine this information is to invoke
+.B select
+with a timeout no greater than the timeout given by \fIares_timeout(3)\fP ).
+.PP
+The
+.B ares_process
+function will invoke callbacks for pending queries if they complete
+successfully or fail.
+.SS EXAMPLE
+The following code fragment waits for all pending queries on a channel
+to complete:
+.PP
+.RS
+.nf
+int nfds, count;
+fd_set readers, writers;
+struct timeval tv, *tvp;
+
+while (1)
+  {
+    FD_ZERO(&readers);
+    FD_ZERO(&writers);
+    nfds = ares_fds(channel, &readers, &writers);
+    if (nfds == 0)
+      break;
+    tvp = ares_timeout(channel, NULL, &tv);
+    count = select(nfds, &readers, &writers, NULL, tvp);

+.SH NAME
+ares_query \- Initiate a single-question DNS query
+.SH SYNOPSIS
+.nf
+.B #include <ares.h>
+.PP
+.B typedef void (*ares_callback)(void *\fIarg\fP, int \fIstatus\fP,
+.B	unsigned char *\fIabuf\fP, int \fIalen\fP)
+.PP
+.B void ares_query(ares_channel \fIchannel\fP, const char *\fIname\fP,
+.B 	int \fIdnsclass\fP, int \fItype\fP, ares_callback \fIcallback\fP,
+.B	void *\fIarg\fP)
+.fi
+.SH DESCRIPTION
+The
+.B ares_query
+function initiates a single-question DNS query on the name service
+channel identified by
+.IR channel .
+The parameter
+.I name
+gives the query name as a NUL-terminated C string of period-separated
+labels optionally ending with a period; periods and backslashes within
+a label must be escaped with a backslash.  The parameters
+.I dnsclass
+and
+.I type
+give the class and type of the query using the values defined in
+.BR <arpa/nameser.h> .
+When the query is complete or has failed, the ares library will invoke
+.IR callback .
+Completion or failure of the query may happen immediately, or may
+happen during a later call to
+.BR ares_process (3)
+or
+.BR ares_destroy (3).
+.PP
+The callback argument
+.I arg
+is copied from the
+.B ares_query
+argument
+.IR arg .
+The callback argument
+.I status
+indicates whether the query succeeded and, if not, how it failed.  It
+may have any of the following values:
+.TP 19
+.B ARES_SUCCESS
+The query completed successfully.
+.TP 19
+.B ARES_ENODATA
+The query completed but contains no answers.
+.TP 19
+.B ARES_EFORMERR
+The query completed but the server claims that the query was
+malformatted.
+.TP 19
+.B ARES_ESERVFAIL
+The query completed but the server claims to have experienced a
+failure.  (This code can only occur if the
+.B ARES_FLAG_NOCHECKRESP
+flag was specified at channel initialization time; otherwise, such
+responses are ignored at the
+.BR ares_send (3)
+level.)
+.TP 19
+.B ARES_ENOTFOUND
+The query completed but the queried-for domain name was not found.
+.TP 19
+.B ARES_ENOTIMP
+The query completed but the server does not implement the operation
+requested by the query.  (This code can only occur if the
+.B ARES_FLAG_NOCHECKRESP
+flag was specified at channel initialization time; otherwise, such
+responses are ignored at the
+.BR ares_send (3)
+level.)
+.TP 19
+.B ARES_EREFUSED
+The query completed but the server refused the query.  (This code can
+only occur if the
+.B ARES_FLAG_NOCHECKRESP
+flag was specified at channel initialization time; otherwise, such
+responses are ignored at the
+.BR ares_send (3)
+level.)
+.TP 19
+.B ARES_EBADNAME
+The query name
+.I name
+could not be encoded as a domain name, either because it contained a
+zero-length label or because it contained a label of more than 63
+characters.
+.TP 19
+.B ARES_ETIMEOUT
+No name servers responded within the timeout period.
+.TP 19
+.B ARES_ECONNREFUSED
+No name servers could be contacted.
+.TP 19
+.B ARES_ENOMEM
+Memory was exhausted.
+.TP 19
+.B ARES_EDESTRUCTION
+The name service channel
+.I channel
+is being destroyed; the query will not be completed.
+.PP
+If the query completed (even if there was something wrong with it, as
+indicated by some of the above error codes), the callback argument
+.I abuf
+points to a result buffer of length
+.IR alen .
+If the query did not complete,
+.I abuf
+will be NULL and
+.I alen
+will be 0.

+.SH NAME
+ares_search \- Initiate a DNS query with domain search
+.SH SYNOPSIS
+.nf
+.B #include <ares.h>
+.PP
+.B typedef void (*ares_callback)(void *\fIarg\fP, int \fIstatus\fP,
+.B	unsigned char *\fIabuf\fP, int \fIalen\fP)
+.PP
+.B void ares_search(ares_channel \fIchannel\fP, const char *\fIname\fP,
+.B 	int \fIdnsclass\fP, int \fItype\fP, ares_callback \fIcallback\fP,
+.B	void *\fIarg\fP)
+.fi
+.SH DESCRIPTION
+The
+.B ares_search
+function initiates a series of single-question DNS queries on the name
+service channel identified by
+.IR channel ,
+using the channel's search domains as well as a host alias file given
+by the HOSTALIAS environment variable.  The parameter
+.I name
+gives the alias name or the base of the query name as a NUL-terminated
+C string of period-separated labels; if it ends with a period, the
+channel's search domains will not be used.  Periods and backslashes
+within a label must be escaped with a backslash.  The parameters
+.I dnsclass
+and
+.I type
+give the class and type of the query using the values defined in
+.BR <arpa/nameser.h> .
+When the query sequence is complete or has failed, the ares library
+will invoke
+.IR callback .
+Completion or failure of the query sequence may happen immediately, or
+may happen during a later call to
+.BR ares_process (3)
+or
+.BR ares_destroy (3).
+.PP
+The callback argument
+.I arg
+is copied from the
+.B ares_search
+argument
+.IR arg .
+The callback argument
+.I status
+indicates whether the query sequence ended with a successful query
+and, if not, how the query sequence failed.  It may have any of the
+following values:
+.TP 19
+.B ARES_SUCCESS
+A query completed successfully.
+.TP 19
+.B ARES_ENODATA
+No query completed successfully; when the query was tried without a
+search domain appended, a response was returned with no answers.
+.TP 19
+.B ARES_EFORMERR
+A query completed but the server claimed that the query was
+malformatted.
+.TP 19
+.B ARES_ESERVFAIL
+No query completed successfully; when the query was tried without a
+search domain appended, the server claimed to have experienced a
+failure.  (This code can only occur if the
+.B ARES_FLAG_NOCHECKRESP
+flag was specified at channel initialization time; otherwise, such
+responses are ignored at the
+.BR ares_send (3)
+level.)
+.TP 19
+.B ARES_ENOTFOUND
+No query completed successfully; when the query was tried without a
+search domain appended, the server reported that the queried-for
+domain name was not found.
+.TP 19
+.B ARES_ENOTIMP
+A query completed but the server does not implement the operation
+requested by the query.  (This code can only occur if the
+.B ARES_FLAG_NOCHECKRESP
+flag was specified at channel initialization time; otherwise, such
+responses are ignored at the
+.BR ares_send (3)
+level.)
+.TP 19
+.B ARES_EREFUSED
+A query completed but the server refused the query.  (This code can
+only occur returned if the
+.B ARES_FLAG_NOCHECKRESP
+flag was specified at channel initialization time; otherwise, such
+responses are ignored at the
+.BR ares_send (3)
+level.)
+.TP 19
+.B ARES_TIMEOUT
+No name servers responded to a query within the timeout period.
+.TP 19
+.B ARES_ECONNREFUSED
+No name servers could be contacted.
+.TP 19
+.B ARES_ENOMEM
+Memory was exhausted.
+.TP 19
+.B ARES_EDESTRUCTION
+The name service channel
+.I channel
+is being destroyed; the query will not be completed.
+.PP
+If a query completed successfully, the callback argument
+.I abuf
+points to a result buffer of length
+.IR alen .
+If the query did not complete successfully,
+.I abuf
+will usually be NULL and
+.I alen
+will usually be 0, but in some cases an unsuccessful query result may
+be placed in
+.IR abuf .

+.SH NAME
+ares_send \- Initiate a DNS query
+.SH SYNOPSIS
+.nf
+.B #include <ares.h>
+.PP
+.B typedef void (*ares_callback)(void *\fIarg\fP, int \fIstatus\fP,
+.B	unsigned char *\fIabuf\fP, int \fIalen\fP)
+.PP
+.B void ares_send(ares_channel \fIchannel\fP, const unsigned char *\fIqbuf\fP,
+.B 	int \fIqlen\fP, ares_callback \fIcallback\fP, void *\fIarg\fP)
+.fi
+.SH DESCRIPTION
+The
+.B ares_send
+function initiates a DNS query on the name service channel identified
+by
+.IR channel .
+The parameters
+.I qbuf
+and
+.I qlen
+give the DNS query, which should already have been formatted according
+to the DNS protocol.  When the query is complete or has failed, the
+ares library will invoke
+.IR callback .
+Completion or failure of the query may happen immediately, or may
+happen during a later call to
+.BR ares_process (3)
+or
+.BR ares_destroy (3).
+.PP
+The callback argument
+.I arg
+is copied from the
+.B ares_send
+argument
+.IR arg .
+The callback argument
+.I status
+indicates whether the query succeeded and, if not, how it failed.  It
+may have any of the following values:
+.TP 19
+.B ARES_SUCCESS
+The query completed.
+.TP 19
+.B ARES_EBADQUERY
+The query buffer was poorly formed (was not long enough for a DNS
+header or was too long for TCP transmission).
+.TP 19
+.B ARES_ETIMEOUT
+No name servers responded within the timeout period.
+.TP 19
+.B ARES_ECONNREFUSED
+No name servers could be contacted.
+.TP 19
+.B ARES_ENOMEM
+Memory was exhausted.
+.TP 19
+.B ARES_EDESTRUCTION
+The name service channel
+.I channel
+is being destroyed; the query will not be completed.
+.PP
+If the query completed, the callback argument
+.I abuf
+points to a result buffer of length
+.IR alen .
+If the query did not complete,
+.I abuf
+will be NULL and
+.I alen
+will be 0.
+.PP
+Unless the flag
+.B ARES_FLAG_NOCHECKRESP
+was set at channel initialization time,
+.B ares_send
+will normally ignore responses whose questions do not match the
+questions in
+.IR qbuf ,
+as well as responses with reply codes of
+.BR SERVFAIL ,
+.BR NOTIMP ,
+and
+.BR REFUSED .
+Unlike other query functions in the ares library, however,
+.B ares_send
+does not inspect the header of the reply packet to determine the error
+status, so a callback status of
+.B ARES_SUCCESS
+does not reflect as much about the response as for other query
+functions.

+.PP
+.B struct timeval *ares_timeout(ares_channel \fIchannel\fP,
+.B	struct timeval *\fImaxtv\fP, struct timeval *\fItvbuf\fP)

+.SH DESCRIPTION
+The
+.B ares_timeout
+function determines the maximum time for which the caller should wait before
+invoking \fIares_process(3)\fP to process timeouts.  The parameter
+.I maxtv
+specifies a existing maximum timeout, or
+.B NULL
+if the caller does not wish to apply a maximum timeout.  The parameter
+.I tvbuf
+must point to a writable buffer of type
+.BR "struct timeval" .
+It is valid for
+.I maxtv
+and
+.I tvbuf
+to have the same value.
+.PP
+If no queries have timeouts pending sooner than the given maximum
+timeout,
+.B ares_timeout
+returns the value of
+.IR maxtv;
+otherwise
+.B ares_timeout
+stores the appropriate timeout value into the buffer pointed to by
+.I tvbuf
+and returns the value of
+.IR tvbuf .

+.SH SYNOPSIS
+.nf
+.B #include <ares.h>
+.PP
+.B const char *ares_version(int *\fIversion\fP)
+.fi
+.SH DESCRIPTION
+The
+.B ares_version
+function gets the library version as a string and optionally as an integer
+stored in the
+.IR version ,
+argument. If you pass a NULL, no integer is attempted to be returned.
+
+The integer is built up as 24bit number, with 8 separate bits used for major
+number, minor number and patch number. This makes a version string such as
+1.2.3 will be returned as the hexadecimal number 0x010203 (decimal 66051).
+.SH NOTES
+This function is not compatible with ares.
