curl_mime_free(3) Library Functions Manual curl_mime_free(3)
NAME
curl_mime_free - free a previously built mime structure
SYNOPSIS
#include <curl/curl.h>
void curl_mime_free(curl_mime *mime);
DESCRIPTION
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) op-
tion: 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 makes this function return immediately
with no action.
PROTOCOLS
This functionality affects http, imap and smtp
EXAMPLE
int main(void)
{
CURL *curl = curl_easy_init();
if(curl) {
/* Build the mime message. */
curl_mime *mime = curl_mime_init(curl);
/* send off the transfer */
/* Free multipart message. */
curl_mime_free(mime);
}
}
AVAILABILITY
