Ok, here's the sample programs i promissed.
poe-test.pl is the most basic one, simple starting a few threads, randomly
picking one and letting it count...
run it and you'll see =)
pt.pl essentially does the same, but it's written in a more abstract way...
feel free to tinker with it a bit.... and learn!
of course, you'll need to install POE as well
you can get it from CPAN ( http://search.cpan.org/search?dist=POE ) and the
tarball holds a samples directory too which is VERY verbose and very
elaborate... for those on a wintendo with AS' ppm, you can use the ppm i
made of the install
just type 'install http://130.115.137.240/poe/POE.ppd' at your ppm prompt
of course, all of this is availabe at poe.perl.org as well.
so now, go POE!
regards,
Jos Boumans
