Add a deprecated attribute to functions and enum values that should not
be used anymore.
This uses a gcc 4.3 dialect, thus is only available for this version of
gcc and newer. Note that the _Pragma() keyword is introduced by C99, but
is available as part of the gcc dialect even when compiling in C89 mode.
It is still possible to disable deprecation at a calling module compile
time by defining CURL_DISABLE_DEPRECATION.
Gcc type checking macros are made aware of possible deprecations.
Some testing support Perl programs are adapted to the extended
declaration syntax.
Several test and unit test C programs intentionally use deprecated
functions/options and are annotated to not generate a warning.
New test 1222 checks the deprecation status in doc and header files.
Closes#9667
you will find a mix of various documentation in this directory and
subdirectories, using several different formats. Some of them are not ideal
for reading directly in your browser.
If you would rather see the rendered version of the documentation, check out the
curl website's documentation section for
general curl stuff or the libcurl section for
libcurl related documentation.
