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](https://c-ares.org/download/),
|
|
and in a git repository: https://github.com/c-ares/c-ares. See the
|
|
[INSTALL.md](INSTALL.md) file for build information.
|
|

regard to c-ares (or by all means the original ares too), get in touch with us

c-ares is of course distributed under the same MIT-style license as the

original ares.

Notes for c-ares hackers
|
|
------------------------
|
|
|
|
* 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 to compile 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 */
|
|
|
|
* Try to keep line lengths below 80 columns.
