Retrieves the specified texture surface level.

Syntax

HRESULT GetSurfaceLevel(      

    UINT Level,
    IDirect3DSurface9 **ppSurfaceLevel
);

Parameters

Level

[in] 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.

ppSurfaceLevel

[out, retval] Address of a pointer to an IDirect3DSurface9 interface, representing the returned surface.

Return Value

If the method succeeds, the return value is D3D_OK.

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