DirectSound Structures
This section contains reference information for the following structures used with DirectSound:
| Programming element | Description |
|---|---|
| DSBCAPS | This structure specifies the capabilities of a DirectSound buffer object, for use by the IDirectSoundBuffer::GetCaps method. |
| DSBPOSITIONNOTIFY | This structure is used by the IDirectSoundNotify::SetNotificationPositions method. |
| DSBUFFERDESC | This structure describes the necessary characteristics of a new DirectSoundBuffer object. |
| DSCAPS | This structure specifies the capabilities of a DirectSound device for use by the IDirectSound::GetCaps method. |
| DSCBCAPS | This structure is used by the IDirectSoundCaptureBuffer::GetCaps method. |
| DSCBUFFERDESC | This structure is used by the IDirectSoundCapture::CreateCaptureBuffer method. |
| DSCCAPS | This structure is used by the IDirectSoundCapture::GetCaps method. |
Note The memory for all DirectX structures must be initialized to zero before use. In addition, all structures that contain a dwSize member must set the member to the size of the structure, in bytes, before use. The following example performs these tasks on a common structure, DSCAPS.
DSCAPS dscaps; // Cannot use this yet.
ZeroMemory(&dscaps, sizeof(dscaps));
dscaps.dwSize = sizeof(dscaps);
// Now the structure can be used.
