IDirectSound::Initialize

The IDirectSound::Initialize method initializes the DirectSound object that was created by using the CoCreateInstance function.

HRESULT Initialize(
  LPGUID lpGuid  
);
 

Parameters

lpGuid

Address of the globally unique identifier (GUID) specifying the sound driver for this DirectSound object to bind to. Pass NULL to select the primary sound driver.

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_ALREADYINITIALIZED
DSERR_GENERIC
DSERR_INVALIDPARAM

Remarks

This method is provided for compliance with the Component Object Model (COM) protocol.
