Does this pass the entire string to the POSTFIELDS input? (My Python skills
are a bit limited.)

Note that you might need to use CURLOPT_POSTFIELDSIZE too to set the size of
the entire POST, if you want to prevent libcurl from using strlen() to figure
it out by itself. It is very odd that you get content-length 0.

If you pass the full string and the correct size, it should work.

What libcurl version is this?

As said in my previous mail, libcurl unfortunately doesn't support sending
POSTs with the READFUNCTION yet. I'm accepting patches from anyone that would
bring this functionality.

Well, strictly speaking that isn't true. You should be able to make it "the
hard way" the way to decribe.
