SYNOPSIS
       ##iinncclluuddee <>

       vvooiidd ccuurrllffoorrmmggeett((ssttrruucctt ccuurrllhhttttppppoosstt **form,  vvooiidd  **arg,    ccuurrllffoorr-
       mmggeettccaallllbbaacckk append));;

DESCRIPTION
       curlformget() is used to serialize data previously built/appended with
       curlformadd(3). Accepts a void pointer as second argument  which  will
       be passed to the curlformgetcallback function.

       ttyyppeeddeeff  ssiizzeett  ((**ccuurrllffoorrmmggeettccaallllbbaacckk))((vvooiidd  **arg, ccoonnsstt cchhaarr **buf,
       ssiizzeett len));;

       The curlformgetcallback will be executed for each part of the HTTP POST
       chain. The void *arg pointer will be the one passed as second argument to
       curlformget(). The character buffer passed to it must not be freed. The
       callback should return the buffer length passed to it on success.
