## Functions
template<class T_action, class T_return, class T_functor>
void | sigc::visit_each (const T_action& _A_action, const retype_return_functor<T_return, T_functor>& _A_target)
| Performs a functor on each of the targets of a functor.
template<class T_return, class T_functor>
retype_return_functor < T_return, T_functor > | sigc::retype_return (const T_functor& _A_functor)
| Creates an adaptor of type sigc::retype_return_functor which performs a C-style cast on the return value of the passed functor.
template<class T_functor>
retype_return_functor <void, T_functor> | sigc::hide_return (const T_functor& _A_functor)
| Creates an adaptor of type sigc::retype_return_functor which drops the return value of the passed functor.
