Functions

func Child

func Child() bool

func ChildOf

func ChildOf(name string) bool

func Maybe

func Maybe(name string, d time.Duration) (forked bool, err error)

Maybe forks the current process if no other run of the binary, in the same install location, has been run in the last duration d.

If d is negative or zero, the touch file is touched and process is forked immediately.

It is an error to call Maybe from a child process forked by Maybe.

It returns an error if any.
