## Detailed Description

### template<typename T_functor, typename... T_type>
struct sigc::retype_functor< T_functor, T_type >

Adaptor that performs C-style casts on the parameters passed on to the functor.

Use the convenience function sigc::retype() to create an instance of retype_functor.

The following template arguments are used:

- T_functor Type of the functor to wrap.
- T_type Types of T_functor's arguments.
