From the man page for CURLOPT_POSTFIELDSIZE:

  If you want to post data to the server without letting libcurl do a strlen() to
  measure the data size, this option must be used. When this option is used you
  can post fully binary data, which otherwise is likely to fail. If this size is
  set to -1, the library will use strlen() to get the size.
