Signal interruption pattern for Go

signal.go

func main() {
	running := true
  
	// Make a channel the signal handler will subscribe 
	sigc := make(chan os.Signal, 1)
	// Notify will send a sigint or sigterm signal to the
	// the previously created channel `sigc`
	signal.Notify(sigc, syscall.SIGINT, syscall.SIGTERM)
  
	go func() {
		for running {
    			// Wait for a signal
			sig := <-sigc
			
			switch sig {
			case syscall.SIGINT:
			case syscall.SIGTERM:
				running = false
			}
		}
	}()
  
  	processing(&running)

	fmt.Println("Interrupted.")
}

func processing(running *bool) {
	for *running {
		// do things...
	}
}
