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.

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

           /* 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);
         }
       }
