#Shutdown.go

A really simple library to help handle the registring of subroutines in go(in priority order)

#Example Code

```

package main

import (

	"fmt"

	"github.com/kcmerrill/shutdown.go"

	"syscall"

	"time"

)

func main() {

    /* Start our application */

	fmt.Println("Listening for shutdown ...")

	/* simulate a shutdown.Now() */

	go DoSomethingToTriggerAShutdown()

	for x := 10000; x >= 0; x-- {

		go worker(x)

	}

	/* Simulate a timeout */

	//shutdown.Timeout("10m")

	//shutdown.WaitFor(syscall.SIGINT, syscall.SIGTERM)

	shutdown.WaitForTimeout("10m", syscall.SIGINT, syscall.SIGTERM) // this is the same as the above two lines

	fmt.Println("\nShutting down ...")

}

func worker(id int) {

	/* Wait for this worker to finish, with a high priority(the lower the number, the faster the shutdown */

	worker := shutdown.WaitForMe(id)

	/* You'd typically put this into your select {} */

	<-worker.Stop()

	/* Tell the world we are ready to shutdown */

	worker.Finished()

}

func DoSomethingToTriggerAShutdown() {

	<-time.After(30 * time.Second)

	fmt.Println("Shutdown() triggered")

	shutdown.Now()

}
