curl_mime_free - free a previously built mime structure
void curl_mime_free(curl_mime *mime);
curl_mime_free(3) is used to clean up data previously built/appended
with curl_mime_addpart(3) and other mime-handling functions. This must
be called when the data has been used, which typically means after
curl_easy_perform(3) has been called.
The handle to free is the one you passed to the CURLOPT_MIMEPOST(3)
option: attached sub part mime structures must not be explicitly freed
as they are by the top structure freeing.
mime is the handle as returned from a previous call to
curl_mime_init(3) and may be NULL.
Passing in a NULL pointer in mime will make this function return
immediately with no action.
/* Build the mime message. */
mime = curl_mime_init(curl);
/* ... */
/* Free multipart message. */
As long as at least one of HTTP, SMTP or IMAP is enabled. Added in
