Functions

func Exit

func Exit(code int)

Exit terminates the application via os.Exit but waits for all exit handlers to complete before calling os.Exit.

func Fatal

func Fatal(v ...interface{})

Fatal is a replacement for log.Fatal which will trigger the closure of all registered exit handlers and waits for their completion and then call os.Exit(1).

func Fatalf

func Fatalf(format string, v ...interface{})

Fatalf is a replacement for log.Fatalf and behaves like Fatal.

func Listen

func Listen(fn func(os.Signal))

Listen registers an exit handler which is called on SIGINT/SIGTERM or when Exit/Fatal/Fatalf is called. SIGHUP is ignored since that is usually used for triggering a reload of configuration which isn't supported but shouldn't kill the process either.

func Wait

func Wait()

Wait waits for all exit handlers to complete.
