Functions

func CatchAll

func CatchAll(sigc chan os.Signal)

func StopCatch

func StopCatch(sigc chan os.Signal)

func Trap added in v1.2.0

func Trap(cleanup func())

Trap sets up a simplified signal "trap", appropriate for common behavior expected from a vanilla unix command-line tool in general (and the Docker engine in particular).

* If SIGINT or SIGTERM are received, `cleanup` is called, then the process is terminated. * If SIGINT or SIGTERM are repeated 3 times before cleanup is complete, then cleanup is skipped and the process terminated directly. * If "DEBUG" is set in the environment, SIGQUIT causes an exit without cleanup.
