Signaled and non signaled state

Question

Described signaled and non signaled state?

Answer 1

An event is into signaled state means that it contains the capacity to release the threads waiting for this event to be signaled. An event is into non signaled state means that it will not release any thread which is waiting for this particular event. Instance in our project: While user clicks the image application icon doubles simultaneously. Two image application windows were formed. Therefore PAIG form an event and set it to non-signaled state. Then the image application will reset the event to signaled state, after this all the threads are released.
