  [in]          UINT              Level,
  [out, retval] IDirect3DSurface9 **ppSurfaceLevel
);

Parameters

[in] Level

Type: UINT

Identifies a level of the texture resource. This method returns a surface for the level specified by this parameter. The top-level surface is denoted by 0.

[out, retval] ppSurfaceLevel

Type: IDirect3DSurface9**

Address of a pointer to an IDirect3DSurface9 interface, representing the returned surface.

Return value

Type: HRESULT

If the method succeeds, the return value is D3D_OK. If the method fails, the return value can be one D3DERR_INVALIDCALL.
