HANDLE
to Timer Object opened with TIMER_MODIFY_STATE
access.
Time when timer should be set, in 100ns units. If it is negative value, it means relative time.
User's APC routine, defined as follows:
typedef void (*PTIMER_APC_ROUTINE)(
IN PVOID TimerContext,
IN ULONG TimerLowValue,
IN LONG TimerHighValue
);
Optional parameter to TimerApcRoutine
.
If set, Power Management restores system to normal mode when timer is signaled.
If zero, timer is set only once. Else will be set periodic in time intervals defined in Period
value (in 100ms units).
Optional pointer to value receiving state of Timer Object before NtSetTimer
call.
