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. None curl_formadd "(3), " curl_mime_init "(3), " curl_mime_free "(3)"
