# NAME
|
|
|
|
curl_multi_cleanup - close down a multi session
|
|
|
|
# SYNOPSIS
|
|
|
|
~~~c
|
|
#include <curl/curl.h>
|
|
|
|
CURLMcode curl_multi_cleanup(CURLM *multi_handle);
|
|
~~~
|
|
|
|
# DESCRIPTION
|
|
|
|
This function is the opposite of curl_multi_init(3). 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.
|
|
|
|
Any use of the **multi_handle** after this function has been called and have
|
|
returned, is illegal.
