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

c-ares
======
This is c-ares, an asynchronous resolver library. It is intended for
applications which need to perform DNS queries without blocking, or need to
perform multiple DNS queries in parallel. The primary examples of such
applications are servers which communicate with multiple clients and programs
with graphical user interfaces.
The full source code is available in the 'c-ares' release archives, and in a
git repository: http://github.com/bagder/c-ares
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 git on a non-configure platform, you must run the
appropriate buildconf* script to set up ares_build.h and other local files
before being able 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_ responsibility to provide this
file. No one at the c-ares project can know how you have built the library.
* File ares_build.h includes platform and configuration dependent info,
and must not be modified by anyone. Configure script generates it for you.
* We cannot assume anything else but very basic compiler features being
present. While c-ares requires an ANSI C compiler to build, some of the
earlier ANSI compilers clearly can't deal with some preprocessor operators.
* Newlines must remain unix-style for older compilers' sake.
* Comments must be written in the old-style /* unnested C-fashion */

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 original libares was distributed at athena-dist.mit.edu:pub/ATHENA/ares.

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!

Library: c-ares, DNS resolver
Version: 1.7.3 (11 June, 2010)
Authors: Greg Hudson, Daniel Stenberg
License: MIT
Notes:
Just use waf instead of the autoconf based configure script. Delete most of
the documentation and other files distributed with it. To upgrade, run
./configure on linux, macintosh, solaris (and other supported platforms) and
copy
- ares_config.h
- ares_setup.h
- ares_build.h
into the appropriate directory.

TODO
====
ares_reinit()
- To allow an app to force a re-read of /etc/resolv.conf etc, pretty much
like the res_init() resolver function offers
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.

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