Overview

Workgroup is a small utility to manage the lifetime of a set of related goroutines.

Examples

http.Serve

var g workgroup.Group

g.Add(func(stop <-chan struct{}) error {
	l, err := net.Listen("tcp", ":80") // listen on port 80
        if err != nil {
                return err
        }

        go func() {
                <-stop // close listener on stop request
                l.Close()
        }()
        return http.Serve(l, mux)
})
g.Run()
