curl_mime_free - free a previously built mime structure

#include <curl/curl.h>

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. */
 curl_mime_free(mime);

As long as at least one of HTTP, SMTP or IMAP is enabled. Added in 7.56.0. None curl_mime_init "(3)"
