16 curl_formget() is used to serialize data previously built/appended with
17 curl_formadd(3). Accepts a void pointer as second argument which will
18 be passed to the curl_formget_callback function.

20 typedef size_t (*curl_formget_callback)(void *arg, const char *buf,
21 size_t len);
22
23 The curl_formget_callback will be executed for each part of the HTTP POST
24 chain. The void *arg pointer will be the one passed as second argument to
25 curl_formget(). The character buffer passed to it must not be freed. The
26 callback should return the buffer length passed to it on success.
