GetDirectDrawSurface method

Retrieves an interface on the underlying IDXSurface::GetDirectDrawSurface object if the DXSurface object is aggregated onto a IDXSurface::GetDirectDrawSurface.

Syntax

HRESULT retVal = object.GetDirectDrawSurface(riid, ppSurface);

Parameters

riid [in]

Type: REFIID

Value that indicates the type of interface to return. This can be any interface ID defined by DirectDraw, such as IID_IDirectDrawSurface, IID_IDirectDrawSurface2, or IID_IDirectDrawSurface3, as exposed by the underlying DirectDraw driver.

ppSurface [out]

Type: void

Address of a pointer to the surface.

Remarks

This method returns E_NOTIMPL if the DXSurface does not have an underlying IDXSurface::GetDirectDrawSurface. This is the case for some surfaces, such as procedural surfaces.
