The IDirectSoundNotify8 interface sets up notification events for a playback or capture buffer.
IDirectSoundNotify8 is a define for IDirectSoundNotify. The two interface names are interchangeable.
The interface is obtained by calling the QueryInterface method of an existing interface on a DirectSound buffer object. Secondary buffers support notifications only if they are created with the DSBCAPS_CTRLPOSITIONNOTIFY flag.
In addition to the methods inherited from IUnknown, the IDirectSoundNotify8 interface exposes the following method.
| Method | Description |
|---|---|
| IDirectSoundNotify8::SetNotificationPositions | The SetNotificationPositions method sets the notification positions. During capture or playback, whenever the read or play cursor reaches one of the specified offsets, the associated event is signaled. |
The LPDIRECTSOUNDNOTIFY type is defined as a pointer to the IDirectSoundNotify interface:
typedef struct IDirectSoundNotify *LPDIRECTSOUNDNOTIFY;
Header: Declared in Dsound.h.
Import Library: Use Dsound3d.dll.
