The methods of the IDirectSoundCaptureBuffer interface are used to manipulate sound capture buffers.
The interface is obtained by calling the IDirectSoundCapture::CreateCaptureBuffer method.
The methods of the IDirectSoundCaptureBuffer interface may be grouped as follows:
| Initialization | Initialize |
| Information | GetCaps |
| GetCurrentPosition | |
| GetFormat | |
| GetStatus | |
| Capture management | Lock |
| Start | |
| Stop | |
| Unlock |
Like all COM interfaces, the IDirectSoundCaptureBuffer interface also inherits the IUnknown interface methods. The IUnknown interface supports the following three methods:
| IUnknown | AddRef |
| QueryInterface | |
| Release |
The LPDIRECTSOUNDCAPTUREBUFFER type is defined as a pointer to the IDirectSoundCaptureBuffer interface:
typedef struct IDirectSoundCaptureBuffer *LPDIRECTSOUNDCAPTUREBUFFER;
