The EngSetEvent function sets the specified event object to the signaled state, and returns the event object's previous state.

Syntax

ENGAPI LONG EngSetEvent(
  [in] PEVENT pEvent
);

Parameters

[in] pEvent

Pointer to the event object that is to be set to the signaled state. This event object was returned by a previous call to EngCreateEvent or EngMapEvent.

Return value

EngSetEvent returns a nonzero value if the event object's previous state was signaled.
