Canceling a Timer Event

  • Article

The application must cancel any outstanding timers by calling the timeKillEvent function before it frees the memory that contains the callback function. To cancel a timer event, it might call the following function.

void DestroyTimer(NPSEQ npSeq)
{
    if(npSeq->wTimerID) {                // is timer event pending?
        timeKillEvent(npSeq->wTimerID);  // cancel the event
        npSeq->wTimerID = 0;
    }
}
