curl_mime_free - free a previously built mime structure
void curl_mime_free(curl_mime *mime);
is used to clean up data previously built/appended
and other mime-handling functions. This must
be called when the data has been used, which typically means after
has been called.
The handle to free is the one you passed to
the CURLOPT_MIMEPOST(3) option: attached subparts 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.
As long as at least one of HTTP, SMTP or IMAP is enabled. Added in 7.56.0.
