For more information about framework timer objects, see Using Timers.
The following code example shows now an EvtTimerFunc callback function can obtain a timer object's parent. In this example, the driver previously specified that the timer object's parent is a queue object.

{
WDFQUEUE queue;
queue = WdfTimerGetParentObject(Timer);
