Re: system() with timeoutby Abigail-II (Bishop) |

Don't do it with system directly, or you might generate zombies. fork(), do an exec() in the child, and then, in
an eval block, setup an alarm handler that does a die(),
set the alarm, waitpid() for your child, cancel the alarm.
Outside the eval block, check for $@, if it indicates the
alarm was triggered, kill the child and waitpid() for it.
No doubt there are some race conditions left in, but it's a start. Abigail
