## Detailed Description

### template<class T_return, class T_functor>
struct sigc::bind_return_functor< T_return, T_functor >

Adaptor that fixes the return value of the wrapped functor.

Use the convenience function sigc::bind_return() to create an instance of sigc::bind_return_functor.

The following template arguments are used:

- T_return Type of the fixed return value.
- T_functor Type of the functor to wrap.
