SignalMap is a map of Linux signals.

Functions

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 ValidSignalForPlatform

func ValidSignalForPlatform(sig syscall.Signal) bool

ValidSignalForPlatform returns true if a signal is valid on the platform
