IDirectSoundNotify8

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.
