Functions

func IgnoreChildStop

func IgnoreChildStop() error

IgnoreChildStop sets the SA_NOCLDSTOP flag, causing child processes to not generate SIGCHLD when they stop.

func StartSignalForwarding

func StartSignalForwarding(handler func(linux.Signal)) func()

StartSignalForwarding ensures that synchronous signals are passed to the given handler function and returns a callback that stops signal delivery.

Note that this function permanently takes over signal handling. After the stop callback, signals revert to the default Go runtime behavior, which cannot be overridden with external calls to signal.Notify.
