Writing a Timer Callback Function
The following callback function, OneShotTimer, invalidates the identifier for
the single timer event and calls a timer routine to handle the
application-specific tasks. For more information, see TimeProc.
- oid CALLBACK OneShotTimer(UINT wTimerID, UINT msg,
DWORD dwUser, DWORD dw1, DWORD dw2)
{
NPSEQ npSeq; // pointer to sequencer data
npSeq = (NPSEQ)dwUser;
npSeq->wTimerID = 0; // invalidate timer ID (no longer in use)
TimerRoutine(npSeq); // handle tasks
}
