 * An example source code that issues a HTTP POST and we provide the actual

 * data through a read callback.

 *

 * Please be aware of the fact that the size of the posted data MUST be

 * specified before the transfer is being made (with CURLOPT_POSTFIELDSIZE).

 * This requirement will change when libcurl starts supporting chunked-encoded

 * sends.

 *

 * This example requires libcurl 7.9.6 or later.
