.SH DESCRIPTION
curl_formget() is used to serialize data previously built/appended with
-\fIcurl_formadd(3)\fP. Accepts a void pointer as second argument which will be
-passed to the curl_formget_callback function.
+\fIcurl_formadd(3)\fP. Accepts a void pointer as second argument named
+\fIuserp\fP which will be passed as the first argument to the
+curl_formget_callback function.

.BI " size_t " len ");"
-.nf
The curl_formget_callback will be executed for each part of the HTTP POST
-chain. The void *arg pointer will be the one passed as second argument to
-curl_formget(). The character buffer passed to it must not be freed. The
+chain. The character buffer passed to the callback must not be freed. The
callback should return the buffer length passed to it on success.
+
+If the \fBCURLFORM_STREAM\fP option is used in the formpost, it will prevent
+\fIcurl_formget(3)\fP from working until you've performed the actual HTTP
+request as only then will libcurl get the actual read callback to use!
