## Detailed Description

### template<class T_return, class T_obj, class T_arg1, class T_arg2>
class sigc::const_volatile_mem_functor2< T_return, T_obj, T_arg1, T_arg2 >

const_volatile_mem_functor2 wraps const volatile methods with 2 argument(s).

Use the convenience function mem_fun() to create an instance of const_volatile_mem_functor2.

The following template arguments are used:

- T_arg1 Argument type used in the definition of operator()().
- T_arg2 Argument type used in the definition of operator()().
- T_return The return type of operator()().
- T_obj The object type.
