KeInitializeTimer routine
The KeInitializeTimer routine initializes a timer object.
Syntax
VOID KeInitializeTimer( __out PKTIMER Timer );
Parameters
- Timer [out]
-
Pointer to a timer object, for which the caller provides the storage.
Return value
None
Remarks
The timer object is initialized to a not-signaled state.
Storage for a timer 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.
KeInitializeTimer can only initialize a notification timer. Use KeInitializeTimerEx to initialize a notification timer or a synchronization timer.
Use KeSetTimer or KeSetTimerEx to define when the timer will expire.
For more information about timer objects, see Timer Objects and DPCs.
Callers of KeInitializeTimer should be running at IRQL = DISPATCH_LEVEL or lower. It is best to initialize timers at IRQL = PASSIVE_LEVEL.
