Detailed Description
template<typename T_return, typename 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.
