curl_free - reclaim memory that has been obtained through a libcurl call
void curl_free( char *ptr );
curl_free reclaims memory that has been obtained through a libcurl call. Use
instead of free() to avoid anomalies that can result from
differences in memory management between your application and libcurl.
Passing in a NULL pointer in ptr will make this function return
immediately with no action.
