NAME

curl_formfree - free a previously build multipart form post chain

SYNOPSIS

#include <curl/curl.h>
void curl_formfree(struct curl_httppost *form);

DESCRIPTION

This function is deprecated. Do not use. See curl_mime_init(3) instead! curl_formfree() is used to clean up data previously built/appended with curl_formadd(3). This must be called when the data has been used, which typically means after curl_easy_perform(3) has been called. The pointer to free is the same pointer you passed to the CURLOPT_HTTPPOST(3) option, which is the firstitem pointer from the curl_formadd(3) invoke(s). form is the pointer as returned from a previous call to curl_formadd(3) and may be NULL. Passing in a NULL pointer in form makes this function return immediately with no action.

PROTOCOLS
