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.

           struct curl_httppost *lastptr;

           /* Fill in a file upload field */
           curl_formadd(&formpost,
