Types ¶

type Handler ¶

type Handler struct {
	sync.Mutex
	// contains filtered or unexported fields
}

Handler waits on a sigint and exits the program after calling the set of callbacks.

var (
	// DefaultHandler is the singleton for this package, because of the nature
	// of os.Exit() there's really no point to have multiple Handler's lying
	// around as only one can ever be executed.
	DefaultHandler *Handler
)

func NewHandler ¶

func NewHandler() *Handler

NewHandler creates a new sigint handler. This starts a goroutine automatically to handle the signal.

func (*Handler) Add ¶

func (h *Handler) Add(callbacks ...func())

Add callbacks to the list of sigint handlers to call when the signal is received.

func (*Handler) Exit ¶

func (h *Handler) Exit(code int)

Exit the process with an exit code.

func (*Handler) Run ¶

func (h *Handler) Run()

Run the handler, waiting for the signal.
