Applications use the methods of the IDirectSoundBuffer interface to create DirectSoundBuffer objects and set up the environment.
The interface is obtained by using the IDirectSound::CreateSoundBuffer method.
The IDirectSoundBuffer methods can be organized into the following groups:
| Information | GetCaps |
| GetFormat | |
| GetStatus | |
| SetFormat | |
| Memory management | Initialize |
| Restore | |
| Play management | GetCurrentPosition |
| Lock | |
| Play | |
| SetCurrentPosition | |
| Stop | |
| Unlock | |
| Sound management | GetFrequency |
| GetPan | |
| GetVolume | |
| SetFrequency | |
| SetPan | |
| SetVolume |
All COM interfaces inherit the IUnknown interface methods. This interface supports the following three methods:
| IUnknown | AddRef |
| QueryInterface | |
| Release |
The LPDIRECTSOUNDBUFFER type is defined as a pointer to the IDirectSoundBuffer interface:
typedef struct IDirectSoundBuffer *LPDIRECTSOUNDBUFFER;
