I'm making my first steps on using shader reflection in DX10. Now the docs say that I must use D3DX10ReflectShader, which will give me a pointer to a ID3D10ShaderReflection1. The 1 at the end leads me to believe it's a DirectX 10.1-structure, as does the remark in the documentation: 'This requires Windows Vista Service Pack 1'. So what happens when I use D3DX10ReflectShader on a Vista that does not have SP1? Can I simply cast the returned pointer to a ID3D10ShaderReflection, thereby maintaining DX 10.0 compatibility?
