KeInitializeEvent

VOID
KeInitializeEvent(
IN PKEVENT Event,
IN EVENT_TYPE Type,
IN BOOLEAN State
);

KeInitializeEvent initializes an event object as a synchronization (single waiter) or notification type event and sets its initial state to Signaled or Not-Signaled.

Parameters

Event: Points to an event object, for which the caller provides the storage.
Type: Specifies the event type, either NotificationEvent or SynchronizationEvent.
State: Specifies the initial state of the event. TRUE indicates Signaled.

Comments

A caller cannot wait at raised IRQL for a nonzero interval on an event object or in a nonarbitrary thread context.

Storage for an event object must be resident: in the device extension of a driver-created device object, in the controller extension of a driver-created controller object, or in nonpaged pool allocated by the caller.

Callers of this routine must be running at IRQL PASSIVE_LEVEL.
