#2879: [asio] Handling of unix signals
 Reporter: dgoncharov_at_[hidden] | Owner: chris_kohlhoff
     Type: Feature Requests | Status: new
Milestone: Boost 1.39.0 | Component: asio
  Version: Boost 1.38.0 | Severity: Problem
 Keywords: |
 This proposal suggests adding to asio the ability to invoke a handler
 whenever a unix signal arrives.


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

 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)
         sigint.async_wait(boost::bind(on_signal, _1));

 The original proposal on the mail list can be found here.

 Please find the implementation and examples in the attachments.
