waiting for process to finishby ovedpo15 (Scribe)
|on Jul 16, 2018 at 06:13 UTC||Need Help??|
ovedpo15 has asked for the wisdom of the Perl Monks concerning the following question:
Consider a function (lets call it A) which returns 1 if a process finished running, otherwise 0.
I would like to write another function which should wait until the process will finish running.
What's the best why to do it?
I thought of using the while loop and the wait(30); command.
Something like this:
I also can just call this subroutine until it will finish, although I don't think its smart because of all unnecessary junk.
What's the best way to do so?
I'm looking for the cleanest way to do it.
