   Changelog for the c-ares project
 
+* May 10, 2006
+
+- Bram Matthys brought my attention to a libtool peculiarity where detecting
+  things such as C++ compiler actually is a bad thing and since we don't need
+  that detection I added a work-around, much inspired by a previous patch by
+  Paolo Bonzini. This also shortens the configure script quite a lot.
+
+* May 3, 2006
+
+- Nick Mathewson added the ARES_OPT_SOCK_STATE_CB option that when set makes
+  c-ares call a callback on socket state changes. A better way than the
+  ares_getsock() to get full control over the socket state.
+
+* January 9, 2006
+
+- Alexander Lazic improved the getservbyport_r() configure check.
+
+* January 6, 2006
+
+- Alexander Lazic pointed out that the buildconf should use the ACLOCAL_FLAGS
+  variable for easier controlling what it does and how it runs.
+
+* January 5, 2006
+
+- James Bursa fixed c-ares to find the hosts file on RISC OS, and made it
+  build with newer gcc versions that no longer defines "riscos".
+
+* December 22
+
+- Daniel Stenberg added ares_getsock() that extracts the set of sockets to
+  wait for action on. Similar to ares_fds() but not restricted to using
+  select() for the waiting.
+
+* November 25
+
+- Yang Tse fixed some send() / recv() compiler warnings
+
+* September 18
+
+- Added constants that will be used by ares_getaddrinfo
+
+- Made ares_getnameinfo use the reentrant getservbyport (getservbyport_r) if it
+  is available to ensure it works properly in a threaded environment.
+
+* September 10
+
+- configure fix for detecting a member in the sockaddr_in6 struct which failed
+  on ipv6-enabled HP-UX 11.00
+
 Version 1.3.0 (August 29, 2004)

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

+
+  Libcurl Install and Use Issues
+  Awaiting an Answer for Win 32 Install 
+  res = curl_easy_perform(curl); Error
+  Makefile Issues
+  
+
+Having previously done a thorough review of what was available that met my
+requirements under GPL, I settled for Libcurl as the software of choice for
+many reasons not the least of which was the support.
+
+Background
+----------
+
+This quest started when I innocently tried to incorporate the libcurl library
+into my simple source code. I figured that a few easy steps would accomplish
+this without major headaches. I had no idea that I would be facing an almost
+insurmountable challenge.
+
+The main problem lies in two areas. First the bulk of support for libcurl
+exists for a Unix/linux command line environments. This is of little help when
+it comes to Windows O/S.
+
+Secondly the help that does exist for the Windows O/S focused around mingw
+thru a command line argument environment.
+
+You may ask "Why is this a problem?"
+
+I'm using a Windows O/S with DevCpp. For those of you who are unfamiliar with
+DevCpp, it is a window shell GUI that replaces the command line environment
+for gcc. A definite improvement that I am unwilling to give up. However using
+DevCpp presented its own set of issues. Inadvertently I also made some
+careless errors such as compiling the 7.14 version of Makefile with an older
+version of source code. Thanks to Dan Fandrich for picking this up.
+
+I did eventually with the help of Daniel, Phillipe and others manage to
+implement successfully (the only mingw available version)
+curl-7.13.0-win32-ssl-devel-mingw32 into the DevCpp environment. Only the
+dynamic libcurl.dll libcurldll.a libraries worked. The static library which I
+was interested in did not. Furthermore when I tried to implement one of the
+examples included with the curl package (get info.c) it caused the executable
+to crash. Tracing the bug I found it in the code and function res =
+curl_easy_perform(curl);.
+
+At this point I had to make a choice as to whether invest my limited
+time-energy resource to fixing the bug or to compile the new version
+available. After searching the archives I found a very similar or the same bug
+reported from version 7.12x on. Daniel did inform me that he thought that this
+bug had been fixed with the latest version. So I proceeded to compile the
+latest SSL version where I faced other challenges.
+
+In order to make this process unremarkable for others using the same
+environment I decided to document the process so that others will find it
+routine. It would be a shame if newbies could not implement this excellent
+package for their use.
+
+I would like to thank the many others in this forum and in the DevCpp forum
+for their help. Without your help I may either have given up or it would have
+taken me many times longer to achieve success.
+
+The Cookbook Approach
+---------------------
+
+This discussion will be confined to a SSL static library compilation and
+installation. Limited mention and comments will be inserted where appropriate
+to help with non-SSL, dynamic libraries and executables.
+
+
+   Using Makefile from DevCpp to compile Libcurl libraries
+
+Preamble
+--------
+
+Using the latest version release - curl-7.14.0.tar.gz. Curl source code is
+platform independent. This simply means that the source code can be compiled
+for any Operating System (Linux/Unix Windows etc. and variations of thereof).
+
+The first thing to note is that inside curl-7.14.0 you will find two folders
+lib and src. Both contain Makefile.m32 (required for win mingw library or exe
+compilation) files which are different. The main difference between these two
+folders and the makefiles is that the src folder contents are used to compile
+an executable file(curl.exe) while the lib folder contents are used to compile
+a static (libcurl.a) and dynamic (libcurl.dll & libcurldll.a) file that can be
+used to compile libcurl with your own source code so that one can use and
+access all libcurl functions.
+
+Before we start please make sure that DevCpp is installed properly. In
+particular make sure you have no spaces in the name of any of the directories
+and subdirectories where DevCpp is installed. Failure to comply with the
+install instructions may produce erratic behaviour in DevCpp. For further info
+check the following sites
+
+http://aditsu.freeunixhost.com/dev-cpp-faq.html
+http://sourceforge.net/forum/message.php?msg_id=3252213
+
+As I have mentioned before I will confine this to the SSL Library compilations
+but the process is very similar for compilation of the executable - curl.exe;
+just substitute the src folder makefile in its stead.
+
+First use a text processor Notepad, or your own favourite text processor. To
+engage your favourite text processor, select Makefile.m32 click once with your
+mouse on file icon; icon turns blue, press the shift key and right-click on
+mouse, menu appears select "Open with", select your favourite text processor.
+
+Next read the contents of Makefile.m32. It includes instructions on its use.
+
+Method I - DOS Command Line
+---------------------------
+ 
+Note - The only reason I have included this method is that Method II which is
+the preferred method for compiling does not allow for the setting of option
+switches (e.g. SSL = 1 or SSL =0). At least that's what they tell me at the
+Dev-Cpp forum.
+
+1 - Make a copy of (D:\Dev-Cpp\bin) bin folder and name it "bin Original"
+place it in the Dev-Cpp installed directory (D:\Dev-Cpp\ for this example)
+
+2 - Copy the entire contents of the LIB folder of curl-7.14.0.tar.gz or zip
+version into the bin folder above (D:\Dev-Cpp\bin). The reason being is that
+the make.exe file resides in this folder. Make.exe will use - Makefile.m32,
+Makefile.inc, and the source code included in the lib folder to compile the
+source code. There is a PATH issue with make.exe that remains unresolved at
+least for me. Unless the entire source code to be compiled is placed entirely
+within the directory of make.exe an error message will be generated - "file
+xxxx.yyy not available".
+
+3- Go to Dev-Cpp\bin and double click on make .exe. You will see a DOS window
+quickly pop up and close very quickly. Not to worry! Please do not skip this
+step.
+
+4- Click on the start button\Programs\MS-DOS Prompt.Once the DOS Window is up
+Type the disk drive letter (e.g. E: ) engage the enter button. The path should
+automatically take you to the directory of the make.exe file.
+
+5- To compile the source code simply type at the DOS prompt make -f
+Makefile.m32 as per instructions contained in the Makefile.m32 file (use any
+text processor to read instructions). I don't believe that this makefile
+allows for the option of non SSL. Ignore any warnings.
+
+6- Collect and make copies of libcurl.a, libcurl.dll, libcurldll.a and any *.o
+compilations you might need in another directory outside of the bin directory
+as you will need this files shortly to set up libcurl for use with
+Dev-cpp. For most apps *.o is not required. Later on we will show what to do
+with these files.
+
+7- You are finished but before closing we need to do cleanup - erase the bin
+folder and rename the "bin Original" folder created in step 1 to bin.
+
+Note to compile a curl executable the process is probably similar but instead
+of using the LIB folder contents use the SRC folder contents and Makefiles in
+curl-7.14.0.tar.gz. File directories relative placements must be respected for
+compiling to take place successfully. This may not be possible with the PATH
+problem that make.exe experiences. If anyone has solved this PATH issue and
+please make sure it actually works on Win 9x/2000/XP before letting me
+know. Then please let me or Daniel in on the solution so that it can be
+included with these instructions. Thanks.
+
+or
+
+Method II - Dev-Cpp GUI
+-----------------------
+
+1- Copy the entire contents of the LIB folder of curl-7.14.0.tar.gz or zip
+version into any folder outside of (Dev-Cpp\bin).
+
+2- Drop the File/New/click on Project.
+
+3- New Project Dialogue box appears. Double click on the Static Library.
+
+4- Create Project Dialogue box appears. Select the LIB folder location to
+place and locate your Project File Name. Placing the Project File Name
+elsewhere may cause problems (PATH issue problem again).
+
+5- Drop down the Project/Project Options. Project Options Dialogue box
+appears.
+
+6- Select the Makefile tab in the Project Options Dialogue Box. Check Box -
+Use Custom Makefile. Click on the Folder icon at the extreme right of the
+Check Box. Select Makefile.m32 in the folder wherever you have placed the
+contents of the LIB Folder. Press OK and close the Dialogue Box.
+
+7- Drop the Menu Project/Click on Add to Project. Open File Dialogue Box
+appears.  The Dialogue Box should open in the folder wherever you have placed
+the contents of the LIB Folder. If not go there.
+
+8- Select Crtl-A to select all files in the LIB folder. Click on open to add
+files and close box. Wait till all files are added. This may take 30 seconds
+or longer.
+
+9- Drop the Menu Execute/Click on Compile. 
+
+10- That's it.
+
+
+   The following steps must be completed if Curl is to work properly
+   =================================================================
+
+LIB folder inclusions (*.a placement)
+-------------------------------------
+
+1- Refer to Method I - DOS Command Line point # 6 Take libcurl.a, libcurldll.a
+and install it in the directory C( or whichever drive Dev is installed)
+:\Dev-Cpp\lib.
+
+
+Include Folder
+--------------
+
+1- Create a new folder by the name of curl (do not change the name curl to
+some other name as it will cause major issues) in the directory
+C:\Dev-Cpp\include.
+
+2- Copy the entire contents of the curl folder of curl-7.14.0.tar.gz or zip
+ version into the newly created curl directory - C:\Dev-Cpp\include\curl.
+
+Links To Include And Lib Folder
+-------------------------------
+
+1- Drop the Menu - Tools\Compiler Options\Directories\Libraries. Make sure
+that C( or whichever drive Dev is installed):\DEV-CPP\lib is included.
+
+2- Next select the Menu - Tools\Compiler Options\Directories\C Includes. Make
+sure that C:\DEV-CPP\include and C:\Dev-Cpp\include\curl are included.
+
+3- Next select the Menu - Tools\Compiler Options\Directories\C++
+Includes. Make sure that C:\DEV-CPP\include and C:\Dev-Cpp\include\curl are
+included.
+
+Linker Links
+------------
+
+1- Drop the Menu - Tools\Compiler Options\Directories\Compiler.
+
+2- Make sure that the box "Add these commands to the linker command line" is
+checked.
+
+3- Include in the white space immediately below the box referred in 2 -lcurl
+-lws2_32 -lwinmm.
+
+SSL Files
+---------
+
+1- Get the latest openSSL (as of time of this writing)
+openssl-0.9.7e-win32-bin.zip for the minimalist package of the openssl-0.9.7e
+binaries ported to MS Windows 95/98/NT/XP using the MingW32/GCC-3.1
+development environment. The file may be downloaded at
+http://curl.haxx.se/download/.
+
+2- Open the above zip file. You will find two files - SDL.dll,
+SDL_mixer.dll. Install them in the directory C:\WINDOWS\SYSTEM32 for Win 9x
+users and c:\winnt\system32 for NT-family users.
+
+Multithreading Files
+--------------------
+
+To be completed
+
+#define
+-------
+
+1- Make sure that your program includes the following - #define CURL_STATICLIB
+must be declared FIRST before any other define functions may be
+added. Otherwise you may experience link errors.
+
+2- Don't forget to include   #include "curl/curl.h".
+
+e.g.
+    #define CURL_STATICLIB 
+#include <windows.h>
+    #include "curl/curl.h"
+#include <fstream>
+#include <iostream>
+#include <vector>
+etc...
+
+
+Static or Dynamic Library
+-------------------------
+
+The above steps apply for the use by a static library. Should you choose to
+use a dynamic library you will be required to perform these additional steps.
+
+1- Refer to Method I - DOS Command Line point # 6. Install libcurl.dll in the
+directory C:\WINDOWS\SYSTEM32 for Win 9x users and c:\winnt\system32 for
+NT-family users.
+
+2- Refer to Linker Links point 3 - Replace -lcurl with -lcurldll.
+
+Voila you're done.
+
+The non-SSL static Library build may not be possible to use at least as of the
+time of this writing - v7.14. Check reference emails - Phillipe and I found it
+impossible to fully compile as certain files were missing for linking. No big
+loss as SSL is a major plus.
+
+Hope this Helps

 You can specify any amount of URLs on the command line. They will be fetched

+
+ http://www.numericals.com/file[1-100:10].txt
+ http://www.letters.com/file[a-z:2].txt
+
+If you specify URL without protocol:// prefix, curl will attempt to guess what
+protocol you might want. It will then default to HTTP but try other protocols
+based on often-used host name prefixes. For example, for host names starting
+with "ftp." curl will assume you want to speak FTP.
+
 Curl will attempt to re-use connections for multiple file transfers, so that
 getting many files from the same server will not do multiple connects /
 handshakes. This improves speed. Of course this is only done on files
 specified on a single command line and cannot be used between separate curl
 invokes.
+.SH "PROGRESS METER"
+curl normally displays a progress meter during operations, indicating amount
+of transfered data, transfer speeds and estimated time left etc.
+
+However, since curl displays data to the terminal by default, if you invoke
+curl to do an operation and it is about to write data to the terminal, it
+\fIdisables\fP the progress meter as otherwise it would mess up the output
+mixing progress meter and response data.
+
+If you want a progress meter for HTTP POST or PUT requests, you need to
+redirect the response output to a file, using shell redirect (>), -o [file] or
+similar.
+
+It is not the same case for FTP upload as that operation is not spitting out
+any response data to the terminal.
+
+If you prefer a progress "bar" instead of the regular meter, \fI-#\fP is your

+ * This example code only builds as-is on Windows.
+ *
+ * Synchronising your computer clock via Internet time server usually relies
+ * on DAYTIME, TIME, or NTP protocols. These protocols provide good accurate
+ * time synchronisation but it does not work very well through a
+ * firewall/proxy. Some adjustment has to be made to the firewall/proxy for
+ * these protocols to work properly.
+ *
+ * There is an indirect method. Since most webserver provide server time in
+ * their HTTP header, therefore you could synchronise your computer clock
+ * using HTTP protocol which has no problem with firewall/proxy.
+ *
+ * For this software to work, you should take note of these items.
+ * 1. Your firewall/proxy must allow your computer to surf internet.
+ * 2. Webserver system time must in sync with the NTP time server,
+ *    or at least provide an accurate time keeping.
+ * 3. Webserver HTTP header does not provide the milliseconds units,
+ *    so there is no way to get very accurate time.
+ * 4. This software could only provide an accuracy of +- a few seconds,
+ *    as Round-Trip delay time is not taken into consideration.
+ *    Compensation of network, firewall/proxy delay cannot be simply divide
+ *    the Round-Trip delay time by half.
+ * 5. Win32 SetSystemTime() API will set your computer clock according to
+ *    GMT/UTC time. Therefore your computer timezone must be properly set.
+ * 6. Webserver data should not be cached by the proxy server. Some
+ *    webserver provide Cache-Control to prevent caching.
+ *
+ * References:
+ * http://tf.nist.gov/timefreq/service/its.htm
+ * http://tf.nist.gov/timefreq/service/firewall.htm
+ *
+ * Usage:
+ * This software will synchronise your computer clock only when you issue
+ * it with --synctime. By default, it only display the webserver's clock.

+.SH DESCRIPTION
+This function converts the given input string to an URL encoded string and
+returns that as a new allocated string. All input characters that are not a-z,
+A-Z or 0-9 are converted to their "URL escaped" version (%NN where NN is a
+two-digit hexadecimal number).
+
+If the \fBlength\fP argument is set to 0 (zero), curl_easy_escape() uses
+strlen() on the input \fBurl\fP to find out the size.
+
+You must \fIcurl_free(3)\fP the returned string when you're done with it.
+.SH AVAILABILITY
+Added in 7.15.4 and replaces the old curl_escape() function.

+.SH DESCRIPTION
+curl_multi_setopt() is used to tell a libcurl multi handle how to behave. By
+using the appropriate options to \fIcurl_multi_setopt\fP, you can change
+libcurl's behaviour when using that multi handle.  All options are set with

+\fBcurl_off_t\fP type, depending on what the specific option expects. Read

+.SH OPTIONS
+.IP CURLMOPT_SOCKETFUNCTION
+Pass a pointer to a function matching the curl_socket_callback prototype. The
+\fIcurl_multi_socket(3)\fP functions inform the application about updates in

+status with changes since the previous time a \fIcurl_multi_socket(3)\fP
+function was called. If the given callback pointer is NULL, no callback will

+See \fIcurl_multi_socket(3)\fP for more callback details.
+.IP CURLMOPT_SOCKETDATA
+Pass a pointer to whatever you want passed to the curl_socket_callback's forth

+.SH DESCRIPTION
+Alternative versions of \fIcurl_multi_perform()\fP that allows the application
+to pass in one of the file descriptors/sockets that have been detected to have
+\&"action" on them and let libcurl perform. This allows libcurl to not have to
+scan through all possible file descriptors to check for action. When the
+application has detected action on a socket handled by libcurl, it should call
+\fIcurl_multi_perform()\fP with the \fBsockfd\fP argument set to the socket
+with the action.
+
+These functions inform the application about updates in the socket (file
+descriptor) status by doing none, one or multiple calls to the
+curl_socket_callback given with the CURLMOPT_SOCKETFUNCTION option to
+\fIcurl_multi_setopt(3)\fP. They update the status with changes since the
+previous time this function was called.
+
+If you want to force libcurl to (re-)check all its internal sockets and
+transfers instead of just a single one, you call
+\fBcurl_multi_socket_all(3)\fP instead.
+
+An application should call \fBcurl_multi_timeout(3)\fP to figure out how long
+it should wait for socket actions \- at most \- before doing the timeout
+action: call the \fBcurl_multi_socket(3)\fP function with the \fBsockfd\fP
+argument set to CURL_SOCKET_TIMEOUT.
+
+The socket \fBcallback\fP function uses a prototype like this
+.nf
+
+     int curl_socket_callback(CURL *easy,      /* easy handle */
+                              curl_socket_t s, /* socket */
+                              int action,      /* see values below */
+                              void *userp);    /* "private" pointer */
+
+.fi
+The callback MUST return 0.
+
+The \fIaction\fP (third) argument to the callback has one of five values:
+.RS
+.IP "CURL_POLL_NONE (0)"
+register, not interested in readiness (yet)
+.IP "CURL_POLL_IN (1)"

+register, interested in both read and write readiness
+.IP "CURL_POLL_REMOVE (4)"
+deregister
+.RE
+.SH "RETURN VALUE"
+CURLMcode type, general libcurl multi interface error code.
+
+If you receive \fICURLM_CALL_MULTI_PERFORM\fP, this basically means that you
+should call \fIcurl_multi_perform\fP again, before you wait for more actions
+on libcurl's sockets. You don't have to do it immediately, but the return code
+means that libcurl may have more data available to return or that there may be
+more data to send off before it is "satisfied".
+
+NOTE that this only returns errors etc regarding the whole multi stack. There
+might still have occurred problems on individual transfers even when this
