curl_formfree - free a multipart/formdata HTTP POST chain
curl_formfree - free a previously build multipart form post chain
#include <curl/curl.h> void curl_formfree(struct curl_httppost *form);
This function is deprecated. Do not use. See curl_mime_init instead!
curl_formfree() is used to clean up data previously built/appended with curl_formadd. This must be called when the data has been used, which typically means after curl_easy_perform has been called.
The pointer to free is the same pointer you passed to the CURLOPT_HTTPPOST option, which is the firstitem pointer from the curl_formadd invoke(s).
form is the pointer as returned from a previous call to curl_formadd 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);
