Microsoft Windows CE .NET 4.2

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;
