Please do not top-post [1]. I don't know why you'd see -1 because in the
version of libcurl you claim to be using the format specifier is %zu [2]
and that should print an unsigned integer not -1. Maybe someone else on
the list can shed some insight on what could be happening there. Try
getting the version string dynamically to see which libcurl is actually
being used:

     printf("%s\n",curl_version_info(CURLVERSION_NOW)->version);

If you need more help please do what I said in my previous e-mail. Also
can you post your write callback function?
