# NAME
curl_mime_free - free a previously built mime structure
# SYNOPSIS
~~~c
#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)
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* makes this function return immediately
with no action.
# %PROTOCOLS%
# EXAMPLE
~~~c
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);
}
}
