Since you set CURLOPT_WRITEFUNCTION as well, libcurl will not even touch
the pointer you set using CURLOPT_WRITEDATA, in your case &chunk. It
will be passed as the userdata param when libcurl invokes your
WriteMemoryCallback. Actual data buffer would be ptr param. Please check
the awesome libcurl documentation for details,
