The IDirectSoundBuffer::Initialize method initializes a DirectSoundBuffer object if it has not yet been initialized.
HRESULT Initialize(
LPDIRECTSOUND lpDirectSound,
LPCDSBUFFERDESC lpcDSBufferDesc
);
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.
DSERR_INVALIDPARAM
DSERR_ALREADYINITIALIZED
Because the IDirectSound::CreateSoundBuffer method calls IDirectSoundBuffer::Initialize internally, it is not needed for the current release of DirectSound. This method is provided for future extensibility.
