c - Time to stop a Linux process using SIGSTOP -


i stopping shell script running, c program. code below: kill(pid, sigstop); wanted know there kernel related delay shell script stopped.

in other words worst case sigstop stop process? there similar delay sigcont ?

kill asynchronous. means time takes unbounded in general. if system heavily loaded, example, take longer. there no bound work 100% of time, if target process otherwise idle.

you must design applications such kill can take arbitrarily long; must not care how long takes. if provide more details why care, can give suggestions how fix that.
