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 will make this function return immediately 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.

RETURN VALUE

None
