## Detailed Description

template <class T_return, class T_functor>
struct sigc::retype_return_functor< T_return, T_functor >

Adaptor that performs a C-style cast on the return value of a functor.

Use the convenience function sigc::retype_return() to create an instance of retype_return_functor.

The following template arguments are used:

- T_return Target type of the C-style cast.
- T_functor Type of the functor to wrap.
