## Detailed Description

template <typename T_functor>
struct sigc::retype_return_functor< void, T_functor >

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

This template specialization is for a void return. It drops the return value of the functor it invokes. Use the convenience function sigc::hide_return() to create an instance of sigc::retype_return_functor<void>.
