Microsoft DirectX 9.0

IDirectSoundFullDuplex8 Interface

The IDirectSoundFullDuplex8 interface represents a full-duplex stream.

The interface is obtained by using the DirectSoundFullDuplexCreate8 function. This function initializes DirectSound capture and playback.

The interface can also be obtained by using CoCreateInstance or CoCreateInstanceEx to create an object of class CLSID_DirectSoundFullDuplex8.

Note   An object of this type can be created on earlier operating systems by using CoCreateInstance or CoCreateInstanceEx. However, a call to Initialize will fail.

IDirectSoundFullDuplex8 is a define for IDirectSoundFullDuplex. The interface names are interchangeable.

In addition to the methods inherited from IUnknown, the IDirectSoundFullDuplex8 interface exposes the following method.

Method Description
Initialize Initializes a full duplex object that was created by using CoCreateInstance.

The LPDIRECTSOUNDFULLDUPLEX type is defined as a pointer to IDirectSoundFullDuplex.

typedef struct IDirectSoundFullDuplex *LPDIRECTSOUNDFULLDUPLEX;


  Header: Declared in dsound.h.

  Operating System: Requires Microsoft Windows XP or later.
