# NAME
curl_multi_cleanup - close down a multi session
# SYNOPSIS
~~~c
#include <curl/curl.h>
CURLMcode curl_multi_cleanup(CURLM *multi_handle);
~~~
# DESCRIPTION
Cleans up and removes a whole multi stack. It does not free or touch any
individual easy handles in any way - they still need to be closed
individually, using the usual curl_easy_cleanup(3) way. The order of
cleaning up should be:
1 - curl_multi_remove_handle(3) before any easy handles are cleaned up
2 - curl_easy_cleanup(3) can now be called independently since the easy
handle is no longer connected to the multi handle
3 - curl_multi_cleanup(3) should be called when all easy handles are
removed
Passing in a NULL pointer in *multi_handle* makes this function return
CURLM_BAD_HANDLE immediately with no other action.
# EXAMPLE
~~~c
int main(void)
{
CURLM *multi = curl_multi_init();
/* when the multi transfer is done ... */
/* remove all easy handles, then: */
curl_multi_cleanup(multi);
}
~~~
# AVAILABILITY
Added in 7.9.6
# RETURN VALUE
CURLMcode type, general libcurl multi interface error code. On success,
CURLM_OK is returned.
