## 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.

## Constructor & Destructor Documentation

template <class T_return , class T_functor >

sigc::bind_return_functor< T_return, T_functor >::bind_return_functor | ( | typename type_trait< T_functor >::take | _A_functor,
|  | typename type_trait< T_return >::take | _A_ret_value |
| ) |  |  | `[inline]`

Constructs a bind_return_functor object that fixes the return value to `_A_ret_value`.

Parameters:

  | _A_functor | Functor to invoke from operator()().
