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:
Allocating memory | Compact |
Initialize | |
Creating buffers | CreateSoundBuffer |
DuplicateSoundBuffer | |
SetCooperativeLevel | |
Device capabilities | GetCaps |
Speaker configuration | GetSpeakerConfig |
SetSpeakerConfig |
The IDirectSound interface, like all COM interfaces, inherits the IUnknown interface methods. The IUnknown interface supports the following three methods:
The LPDIRECTSOUND type is defined as a pointer to the IDirectSound interface:
typedef struct IDirectSound *LPDIRECTSOUND;
