Windows compilers define `_WIN32` automatically. Windows SDK headers or build env defines `WIN32`, or we have to take care of it. The agreement seems to be that `_WIN32` is the preferred practice here. Make the source code rely on that to detect we're building for Windows. Public `curl.h` was using `WIN32`, `__WIN32__` and `CURL_WIN32` for Windows detection, next to the official `_WIN32`. After this patch it only uses `_WIN32` for this. Also, make it stop defining `CURL_WIN32`. There is a slight chance these break compatibility with Windows compilers that fail to define `_WIN32`. I'm not aware of any obsolete or modern compiler affected, but in case there is one, one possible solution is to define this macro manually. grepping for `WIN32` remains useful to discover Windows-specific code. Also: - extend `checksrc` to ensure we're not using `WIN32` anymore. - apply minor formatting here and there. - delete unnecessary checks for `!MSDOS` when `_WIN32` is present.

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. 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.
