curl_multi_get_handles(3) Library Functions Manual curl_multi_get_handles(3)
NAME
curl_multi_get_handles - return all added easy handles
SYNOPSIS
#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.
PROTOCOLS
This functionality affects all supported protocols
EXAMPLE
int main(void)
{
/* init a multi stack */
CURLM *multi = curl_multi_init();
CURL *curl = curl_easy_init();
if(curl) {
/* add the transfer */
curl_multi_add_handle(multi, curl);
/* extract all added handles */
CURL **list = curl_multi_get_handles(multi);
if(list) {
int i;
/* remove all added handles */
for(i = 0; list[i]; i++) {
curl_multi_remove_handle(multi, list[i]);
}
curl_free(list);
}
}
}
AVAILABILITY
Added in curl 8.4.0
RETURN VALUE
Returns NULL on failure. Otherwise it returns a pointer to an allocated
array.
