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¶

This functionality affects http only

EXAMPLE¶

int main(void)
{


  CURL *curl = curl_easy_init();


  if(curl) {

    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);


  }
