Suppress deprecation warnings the closest to the deprecated code, using
`CURL_IGNORE_DEPRECATION()`. Then drop build-specific suppressions, and
file-wide ones. The latter is not compatible with Unity mode. Also
replace manual suppressions with a macro to apply to all compilers with
deprecation warning support. Also enable deprecation warnings for clang.
- curl/curl.h: enable deprecation warnings for clang.
- docs/examples: stop setting `CURL_DISABLE_DEPRECATION` with autotools.
Suppression moved to C-level earlier. Syncs with cmake.
Follow-up to 5fc61a37c1#14123
- tests/http/clients: stop setting `CURL_DISABLE_DEPRECATION` in
autotools. If it becomes necessary in the future, it can be done in
C via the macro. Syncs with cmake.
- lib1545: stop setting `CURL_DISABLE_DEPRECATION` in autotools.
Drop guard from test source.
Follow-up to 0f10360073#12444
- libtest, unit: replace `CURL_DISABLE_DEPRECATION` with
`CURL_IGNORE_DEPRECATION()`.
- docs/examples: replace pragmas with `CURL_IGNORE_DEPRECATION()`.
Closes#14789
This directory is for libcurl programming examples. They are meant to show
some simple steps on how you can build your own application to take full
advantage of libcurl.
If you end up with other small but still useful example sources, please mail
them for submission in future packages and on the website.
Building
The Makefile.example is an example Makefile that could be used to build
these examples. Just edit the file according to your system and requirements
first.
Most examples should build fine using a command line like this:
`curl-config --cc --cflags --libs` -o example example.c
Some compilers do not like having the arguments in this order but instead
want you do reorganize them like:
`curl-config --cc` -o example example.c `curl-config --cflags --libs`
Please do not use the curl.se site as a test target for your libcurl
applications/experiments. Even if some of the examples use that site as a URL
at some places, it does not mean that the URLs work or that we expect you to
actually torture our website with your tests. Thanks.
Examples
Each example source code file is designed to be and work stand-alone and
rather self-explanatory. The examples may at times lack the level of error
checks you need in a real world, but that is then only for the sake of
readability: to make the code smaller and easier to follow.
