curl_formfree(3) Library Functions Manual curl_formfree(3)

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

EXAMPLE


int main(void)
{
CURL *curl = curl_easy_init();
if(curl) {
struct curl_httppost *formpost;
struct curl_httppost *lastptr;

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);
}
}

DEPRECATED

Deprecated in 7.56.0.
