IDirectSound
Applications use the methods of the IDirectSound interface to create DirectSound objects and set up the environment. This section is a reference to the methods of this interface.
The interface is obtained by using the DirectSoundCreate function.
The methods of the IDirectSound interface can be organized into the following groups:
| Initialization | Initialize |
| SetCooperativeLevel | |
| Buffer creation | CreateSoundBuffer |
| DuplicateSoundBuffer | |
| Device capabilities | GetCaps |
| Memory management | Compact |
| Speaker configuration | Not supported on Windows CE |
The IDirectSound interface, like all COM interfaces, inherits the IUnknown interface methods. The IUnknown interface supports the following three methods:
| IUnknown | AddRef |
| QueryInterface | |
| Release |
The LPDIRECTSOUND type is defined as a pointer to the IDirectSound interface.
typedef struct IDirectSound *LPDIRECTSOUND;
