# NAME
|
|
|
|
curl_multi_remove_handle - remove an easy handle from a multi session
|
|
|
|
# SYNOPSIS
|
|
|
|
~~~c
|
|
#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.
|
|
|
|
# EXAMPLE
|
|
|
|
~~~c
|
|
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);
|
|
}
|
|
}
|
|
}
