wait_eventT_wait_eventWaitEventWaitEventwait_event — Lock an event synchronization object.

wait_event( : : EventHandle : )

wait_eventwait_eventWaitEventWaitEventWaitEventwait_event waits on the event object passed in EventHandleEventHandleEventHandleEventHandleeventHandleevent_handle until it is signaled. When the event is signaled, wait_eventwait_eventWaitEventWaitEventWaitEventwait_event succeeds and sets the state automatically to non-signaled again. The kind of wait depends on the event's attributes set during the creation in create_eventcreate_eventCreateEventCreateEventCreateEventcreate_event.

Multithreading type: independent (runs in parallel even with exclusive operators).
多线程作用域:全局(可以从任何线程调用)。
未经并行化处理。
