External Processes

[Darren Smith]

I use the system() function to call an external program. How can I limit
the amount of time it runs or the amount of space it occupies? Also how
would I get error information returned to me?

Thanks,
Darren.

That is a function of you operating system, see e.g. "man ulimit".

Also how would I get error information returned to me?

See the perldoc page for system(), third paragraph.
