Description

Methods

	constructor create(realTime: bool = false; isIn: bool = true; overNum: unsigned = 0);

	function addHeader(header: unaWaveHeader): MMRESULT; override;

	function afterOpen(): MMRESULT; override;

	function getMasterIsSrc2(): bool; override;
Returns true.

	function onHeaderDone(header: unaWaveHeader; wakeUpByHeaderDone: bool): bool; override;

	function open2(query: bool = false; timeout: tTimeout = 10005; flags: uint = 0; startDevice: bool = true): MMRESULT; override;

	function prepareHeader(header: pointer): MMRESULT; override;

	function setFormat(isSrc: bool; format: pWAVEFORMATEX): bool; override;
WARNING! this call will change the realtime clock interval. so, be careful when setting the format of realtime devices with non-default timer interval.

	function unprepareHeader(header: pointer): MMRESULT; override;

	procedure AfterConstruction(); override;

	procedure BeforeDestruction(); override;

	procedure afterClose(closeResult: MMRESULT); override;

	procedure onTick(sender: tObject); virtual;

	procedure setRealTime(value: bool); override;

Properties

	property realTimer: unaAbstractTimer read f_realTimer;
