Starting a Single Timer Event
To start a single timer event, an application must call the timeSetEvent function, specifying the amount of time before the callback occurs, the
resolution, the address of the callback function (see TimeProc), and the user data to supply with the callback function. An application can
use a function like the following to start a single timer event.
UINT SetTimerCallback(NPSEQ npSeq, // sequencer data
UINT msInterval) // event interval
{
npSeq->wTimerID = timeSetEvent(
msInterval, // delay
wTimerRes, // resolution (global variable)
OneShotCallback, // callback function
(DWORD)npSeq, // user data
TIME_ONESHOT ); // single timer event
if(! npSeq->wTimerID)
return ERR_TIMER;
else
return ERR_NOERROR;
}
For an example of the callback function OneShotCallback, see Writing a Timer Callback Function.
