< p class = "level0" > curl_formget() is used to serialize data previously built/appended with < a class = "emphasis" href = "./curl_formadd.html" > curl_formadd(3)< / a > . Accepts a void pointer as second argument which will be passed to the curl_formget_callback function.

< p class = "level0" > < p class = "level0" > 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
callback should return the buffer length passed to it on success.
