SignalMap is a map of Linux signals.

Functions

func CatchAll

func CatchAll(sigc chan os.Signal)

CatchAll catches all signals and relays them to the specified channel.

func ParseSignal

func ParseSignal(rawSignal string) (syscall.Signal, error)

ParseSignal translates a string to a valid syscall signal. It returns an error if the signal map doesn't include the given signal.

func ParseSignalNameOrNumber

func ParseSignalNameOrNumber(rawSignal string) (syscall.Signal, error)

ParseSignalNameOrNumber translates a string to a valid syscall signal. Input can be a name or number representation i.e. "KILL" "9".

func StopCatch

func StopCatch(sigc chan os.Signal)

StopCatch stops catching the signals and closes the specified channel.
