2879,[asio] Handling of unix signals,dgoncharov@…,chris_kohlhoff,"This proposal suggests adding to asio the ability to invoke a handler whenever a unix signal arrives.

Motivation:

1. The extension lets the user have a unix signal handler of an arbitrary signature. 

2. The extension also removes the ""async-signal safe calls"" restriction from a handler of a unix signal.

The extension is supposed to be used like this:

void on_signal(boost::system::error_code const& error) 
{ 
    if (!error) 
        cout << ""sigint received"" << endl; 
} 

int main(int argc, char const* argv[])

{
    boost::asio::io_service ios; 
    boost::asio::posix::signal_handler<SIGINT> sigint(ios); 
    while (true) 
    { 
        ios.reset(); 
        sigint.async_wait(boost::bind(on_signal, _1)); 
        ios.poll(); 
    }
}
