You already got a link to documentation in the other thread.
https://curl.se/libcurl/c/
Use it.
For example, for
CURLOPT_CAINFO you would click on
curl_easy_setopt, then search for
CURLOPT_CAINFO and finally get here:
https://curl.se/libcurl/c/CURLOPT_CAINFO.html
Also google for curl tutorials and examples. They may be in C, but the API is very similar.
If you use linux or WSL you can always play with "curl" from command line to get a better feel for how it works. For example:
Code:
curl https://lexzor.warface.ro/AutoUpdate/Test/version.txt
will give you:
Code:
snip:~$ curl https://lexzor.warface.ro/AutoUpdate/Test/version.txt
999
snip:~$
