Also repurpose existing build-time feature checks into unit test 1961,
to verify.
Prior to this patch these functions were auto-detected with both
autotools and cmake. In case of autotools there was an extra
verification phase ensuring the functions work as expected. This step
required running the function, thus was limited to non-cross-builds. For
cross-builds and CMake it always used the system implementation if
present. On Windows it always used the local implementation, because
availability/use is complicated there.
After this patch all platforms, always use the local implementation,
which is known to be accurate. This makes curl behave more consistently,
and simplifies the build process, a fixes cross-builds and CMake
auto-detection differences.
Also:
- test1960: enable unconditionally.
- checksrc: disallow globally, allowlist in `block_ip.c` example.
- dnsd: verify ntop result for NULL before passing to printf.

libcurl examples
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. 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-my 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-my 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.
