Gets the depth-stencil surface owned by the Direct3DDevice object.
- ppZStencilSurface [out, retval]
Address of a pointer to an IDirect3DSurface9 interface, representing the returned depth-stencil surface.
If the method succeeds, the return value is D3D_OK.If the device doesn't have a depth stencil buffer associated with it, the return value will be D3DERR_NOTFOUND. Otherwise, if the method fails, the return value can be D3DERR_INVALIDCALL.
Calling this method will increase the internal reference count on the IDirect3DSurface9 interface. Failure to call IUnknown::Release when finished using this IDirect3DSurface9 interface results in a memory leak.
