DSBPOSITIONNOTIFY

The DSBPOSITIONNOTIFY structure is used by the IDirectSoundNotify::SetNotificationPositions method.

typedef struct {
    DWORD   dwOffset;
    HANDLE  hEventNotify;
} DSBPOSITIONNOTIFY, *LPDSBPOSITIONNOTIFY;
 
typedef const DSBPOSITIONNOTIFY *LPCDSBPOSITIONNOTIFY;

Members

dwOffset

Offset from the beginning of the buffer where the notify event is to be triggered, or DSBPN_OFFSETSTOP.

hEventNotify

Handle to the event to be signaled when the offset has been reached.

Remarks

The DSBPN_OFFSETSTOP value in the dwOffset member causes the event to be signaled when playback or capture stops, either because the end of the buffer has been reached (and playback or capture is not looping) or because the application called the IDirectSoundBuffer::Stop or IDirectSoundCaptureBuffer::Stop method.

Note  When using LOC_DEFER and NOTIFY along with any voice management TERMINATEBY flag, it is possible that a sound that has notifications set, but not yet reached, may be terminated by the voice manager. In this event, the notification event will not occur.
