Right, but the docs says you should return 0 then.

The callback returns an unsigned value so your -1 becomes a very large number
and recent libcurls consider you returning a value larger than the buffer size
as a sign of a sever failure and will return error.

You should really check the return code from curl_easy_perform() as that will
offer clues when things go wrong.
