# NAME
|
||
|
|
|
||
|
|
curl_multi_get_handles - returns all added easy handles
|
||
|
|
|
||
|
|
# SYNOPSIS
|
||
|
|
|
||
|
|
~~~c
|
||
|
|
#include <curl/curl.h>
|
||
|
|
|
||
|
|
CURL **curl_multi_get_handles(CURLM *multi_handle);
|
||
|
|
~~~
|
||
|
|
|
||
|
|
# DESCRIPTION
|
||
|
|
|
||
|
|
Returns an array with pointers to all added easy handles. The end of the list
|
||
|
|
is marked with a NULL pointer.
|
||
|
|
|
||
|
|
Even if there is not a single easy handle added, this still returns an array
|
||
|
|
but with only a single NULL pointer entry.
|
||
|
|
|
||
|
|
The returned array contains all the handles that are present at the time of
|
||
|
|
the call. As soon as a handle has been removed from or a handle has been added
|
||
|
|
to the multi handle after the handle array was returned, the two data points
|
||
|
|
are out of sync.
|
||
|
|
|
||
|
|
The order of the easy handles within the array is not guaranteed.
|
||
|
|
|
||
|
|
The returned array must be freed with a call to curl_free(3) after use.

|
/* add the transfer */
|
||
|
|
curl_multi_add_handle(multi, curl);
