Question regarding graceful exit from poll

[Mark Jeffery]

I would like to understand the best practice for gracefully exiting a poll loop when using this library (or zmq poll in general)

I have the following crude example, which works fine : Is there a more elegant way to do it ?

I realize there is only 1 socket in this example but more will be added.

Eish:
	for {

		sockets, _ := poller.Poll(time.Second * 3)

		for _, socket := range sockets {
			switch s := socket.Socket; s {
			case sub1:
				address, err := s.Recv(0)
				if err != nil {
					log.Errorf("Error receiving zmq message(1) : %v", err)
					continue
				}
				if msg, err := s.Recv(0); err != nil {
					log.Errorf("Error receiving zmq message(2) : %v", err)
					continue
				} else {
					mess := string(msg)
					fmt.Print("Received message from " + address + " channel.")
					fmt.Printf("%+v\n", mess)
				}
			}

		}

		select {
		case <-ctx.Done():
			log.Infof("Exiting zmq.")
			break Eish
		case <-time.After(time.Millisecond * 1):
		}

	}
