Functions ¶

func Maybe ¶

func Maybe(wait time.Duration, fatalf func(format string, args ...any)) (parent bool)

Maybe forks the current process if no other run of the binary in the same install location has been run within the amount of time specified by wait.

If an error occurs and fatalf is non-nil, the error is logged to fatalf; otherwise no error is logged.

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