## Example

```

	// Generate a new context

	ctx := NewContext()

	// Run service with this context

	go func(ctx context.Context) {

		if err := ExitWaitGroupAdd(ctx, 1); err != nil {

			return

		}

		defer ExitWaitGroupDone(ctx)

		otherEvent := make(chan struct{})

	FOR_LOOP:

		for {

			select {

			case <-ctx.Done():

				break FOR_LOOP

			case <-otherEvent:

				// ...

			}

		}

		

		// Some close processes

	}(ctx)

	// Wait interrupt signal and shutdown gracefully

	if err := WaitAndShutdown(ctx, time.Second*5, func(timeout time.Duration) error {

		log.Println("close")

		return nil

	}); err != nil {

		log.Println("Shutdown error:", err)

		return

	}
