event object

A user-mode object upon which one or more threads can wait until the event is set to the signaled state. Every user-mode event object is implemented through the use of a kernel-mode event object.

A kernel-mode event object is an instance of a kernel-defined dispatcher object type. Each kernel-mode event can be classified as either of the following:

    1. When a synchronization event (a.k.a. “autoclearing event”) is set to the signaled state, a single thread waiting on the event is released (its dispatch state transitions from waiting to ready, standby, or running), and an autoreset to not-signaled occurs.

    2. When a notification event is set to the signaled state, all threads waiting on the event are released, and the event remains in the Signaled state until an explicit reset to not-signaled occurs.
