KeClearEvent function (wdm.h)
The KeClearEvent routine sets an event to a not-signaled state.
Syntax
void KeClearEvent(
[in, out] PRKEVENT Event
);
Parameters
[in, out] Event
Pointer to an initialized dispatcher object of type event for which the caller supplies the storage.
Return value
None
Remarks
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.
