SignalMap is a map of Linux signals.
Functions ¶
func CatchAll ¶
CatchAll catches all signals and relays them to the specified channel. SIGURG is not handled, as it's used by the Go runtime to support preemptable system calls.
func ParseSignal ¶
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 ¶
ValidSignalForPlatform returns true if a signal is valid on the platform
