NAME
curl_formfree - free a previously build multipart/formdata HTTP 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_HTTP-
POST(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 will make this function return imme-
diately with no action.
EXAMPLE
/* Fill in a file upload field */
curl_formadd(&formpost,
&lastptr,
CURLFORM_COPYNAME, "file",
CURLFORM_FILE, "nice-image.jpg",
CURLFORM_END);
curl_easy_setopt(curl, CURLOPT_HTTPPOST, formpost);
curl_easy_perform(curl);
/* then cleanup the formpost chain */
curl_formfree(formpost);
AVAILABILITY
Deprecated in 7.56.0.
