curl_multi_wakeup(3) libcurl Manual curl_multi_wakeup(3) NAME curl_multi_wakeup - wakes up a sleeping curl_multi_poll call SYNOPSIS #include <curl/curl.h> CURLMcode curl_multi_wakeup(CURLM *multi_handle); DESCRIPTION This function can be called from any thread and it wakes up a sleeping curl_multi_poll(3) call that is currently (or will be) waiting for activity or a timeout. If the function is called when there is no curl_multi_poll(3) call, it will cause the next call to return immediately. Calling this function only guarantees to wake up the current (or the next if there is no current) curl_multi_poll(3) call, which means it is possible that multiple calls to this function will wake up the same waiting operation. This function has no effect on curl_multi_wait(3) calls. EXAMPLE CURL *easy_handle; CURLM *multi_handle; /* add the individual easy handle */ curl_multi_add_handle(multi_handle, easy_handle); /* this is thread 1 */ do { CURLMcode mc; int numfds; mc = curl_multi_perform(multi_handle, &still_running); if(mc == CURLM_OK) { /* wait for activity, timeout or wakeup */ mc = curl_multi_poll(multi_handle, NULL, 0, 10000, &numfds); } if(time_to_die()) exit(1); } while(still_running); curl_multi_remove_handle(multi_handle, easy_handle); /* this is thread 2 */ if(something makes us decide to stop thread 1) { set_something_to_signal_thread_1_to_exit(); curl_multi_wakeup(multi_handle); } AVAILABILITY Added in 7.68.0 RETURN VALUE CURLMcode type, general libcurl multi interface error code.
