IDirect3D3::CreateLight

The IDirect3D3::CreateLight method allocates a Direct3DLight object. This object can then be associated with a viewport by using the IDirect3DViewport3::AddLight method.

HRESULT CreateLight(
  LPDIRECT3DLIGHT* lplpDirect3DLight,  
  IUnknown* pUnkOuter                  
);

Parameters

lplpDirect3DLight
Address that will be filled with a pointer to an IDirect3DLight interface if the call succeeds.
pUnkOuter
This parameter is provided for future compatibility with COM aggregation features. Currently, however, the IDirect3D3::CreateLight method returns an error if this parameter is anything but NULL.

Return Values

If the method succeeds, the return value is D3D_OK.

If the method fails, the return value may be one of the following values:

DDERR_INVALIDOBJECT
DDERR_INVALIDPARAMS

Remarks

This method is unchanged from its implementation in the IDirect3D2 interface.
