Thanks for your kind words.

That is the old name, it is currently named --request instead and you may use
DELETE in a way similar to:

        curl --request DELETE http://that.site.com/removefile.html

Yes, it is fully implemented. Feel free to suggest how this can be added
properly to the documentation.

They're all typedef'ed enums named CURLcode. All functions that are defined
to receive such a variable can receive one of those return codes.

The curl tool is made to return the (last) return code from
curl_easy_perform() to whoever invoked it (most likely a shell).

curl_easy_perform() returns different return codes depending on the cause of
its failure. I think you're seeing something wrong if that return code is
always 0. Just make it do an error and single-step through the code to find
out exactly why/how.
