IDirectSound::Initialize

  • Article

This 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 to which this DirectSound object binds. Pass NULL to select the primary sound driver.

Return Values

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
DSERR_NODRIVER

Remarks

This method is provided for compliance with the Component Object Model (COM) protocol. If the DirectSoundCreate function was used to create the DirectSound object, this method returns DSERR_ALREADYINITIALIZED. If IDirectSound::Initialize is not called when using CoCreateInstance to create the DirectSound object, any method called afterward returns DSERR_UNINITIALIZED.

On Windows CE, CoCreateInstance cannot be use to create the DirectSound object on CE. DirectSoundCreate should be used instead. This method always returns DSERR_ALREADY_INITIALIZED.

Requirements

OS Versions: Windows CE 2.12 and later. Version 2.12 requires DXPAK 1.0 or later.
Header: Dsound.h.
Link Library: Dsound.lib.
