IDirectSoundCaptureBuffer8::Initialize Method

[The feature associated with this page, DirectSound, is a legacy feature. It has been superseded by WASAPI and Audio Graphs. Media Casting have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use Media Casting instead of DirectSound, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]

The Initialize method initializes a capture buffer object. Because the IDirectSoundCapture8::CreateCaptureBuffer method and the DirectSoundFullDuplexCreate8 function call the IDirectSoundCaptureBuffer8::Initialize method internally, this method is not used by applications.

Syntax

HRESULT Initialize(
         LPDIRECTSOUNDCAPTURE pDirectSoundCapture,
         LPCDSCBUFFERDESC pcDSCBufferDesc
)

Parameters

  • pDirectSoundCapture
    Address of the DirectSoundCapture object associated with this DirectSoundCaptureBuffer object.
  • pcDSCBufferDesc
    Address of a DSCBUFFERDESC structure that contains the values used to initialize this sound buffer.

Return Value

If the method succeeds, the return value is DS_OK. If the method fails, the return value may be one of the following error values:

Return code
DSERR_INVALIDPARAM
DSERR_ALREADYINITIALIZED

Requirements

Header: Declared in DSound.h.
