specialization of a template who has a parameter

I got the following template

template<class T, class U, bool(*function)(T)>  struct foo {  /.../  }  

How do I create a specialization for it? The spcialization should be like the following

template<>  struct foo<my_type_1, my_type_2,/*how do I handle this parameter?*/>  

My main question is how do I handle the parameter of the funcion?

thanks in advance
