curl_multi_remove_handle(3) Library Functions Manual
NAME
curl_multi_remove_handle - remove an easy handle from a multi session
SYNOPSIS
#include <curl/curl.h>
CURLMcode curl_multi_remove_handle(CURLM *multi_handle, CURL *easy_handle);
DESCRIPTION
Removes a given easy_handle from the multi_handle. This makes the
specified easy handle be removed from this multi handle's control.
When the easy handle has been removed from a multi stack, it is again
perfectly legal to invoke curl_easy_perform(3) on this easy handle.
Removing an easy handle while being in use is perfectly legal and
effectively halts the transfer in progress involving that easy handle.
All other easy handles and transfers remain unaffected.
It is fine to remove a handle at any time during a transfer, just not
from within any libcurl callback function.
Removing an easy handle from the multi handle before the corresponding
transfer is complete might cause libcurl to close the connection - if
the state of it and the internal protocol handler deem it necessary.
Otherwise libcurl keeps the connection alive in the connection pool
associated with the multi handle, ready to get reused for a future
transfer using this multi handle.
PROTOCOLS
This functionality affects all supported protocols
EXAMPLE
int main(void)
{
CURLM *multi = curl_multi_init();
int queued = 0;
/* when an easy handle has completed, remove it */
CURLMsg *msg = curl_multi_info_read(multi, &queued);
if(msg) {
if(msg->msg == CURLMSG_DONE) {
/* a transfer ended */
fprintf(stderr, "Transfer completed\n");
curl_multi_remove_handle(multi, msg->easy_handle);
}
}
}
AVAILABILITY

RETURN VALUE
