curl_formfree - free a previously build multipart/formdata HTTP POST chain

#include <curl/curl.h>

*void curl_formfree(struct curl_httppost **/form);/

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.

    /* 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);

Deprecated in 7.56.0.
