Timer callback routine.

Parameters

Parameters	Description
Arg	Application defined value as passed to SetTimerApc.

Apc	High order 32-bits of the UTC based time when the timer was signaled. This value corresponds to the dwHighDateTime value of a TFileTime record.

Description

TFNTimerAPCRoutine is used as the callback routine for waitable timers. The procedure is executed when the waitable timer becomes signaled in the context of the thread that activated the timer using the SetTimer or SetTimerApc method. However, that thread must be in an alertable state or the completion routine will be cancelled.
