KeClearEvent function (wdm.h)

The KeClearEvent routine sets an event to a not-signaled state.

Syntax

void KeClearEvent(
  [in, out] PRKEVENT Event
);

[in, out] Event

Pointer to an initialized dispatcher object of type event for which the caller supplies the storage.

None

Event is set to a not-signaled state, meaning its value is set to zero.

For better performance, use KeClearEvent unless the caller uses the value returned by KeResetEvent to determine what to do next.

For more information about event objects, see Event Objects.
