Re: forking and timeouts

The test in the sub is suspect:

return 0 if $pid < 0;

~~Can a pid be a negative number? I think not (but stand to be corrected).~~

Clarify, Correct: Can $pid be a negative number? I don't see anything in your code to support that (but still stand to be corrected).

Can $pid be a negative number? In this case `$pid` is the return value of `wait`, which is (according to the docs) ...the pid of the deceased process, or "-1" if there are no child processes.	[reply] [d/l] [select]
