Hi; This seems like a very simple concept, but I'm not getting it, so I'd like some help. So part of this is perl (not understanding readdir and/or glob well enough) and part of it is not getting the logic right. I have five perl scripts. I do not want any of them running concurrently a

RE: Concurrency problem

Sorry :) but your script seems not doing what you explained above. I have the impression that your problem is not related to a concurrency problem. Could you send a more detailed code, please? José. Anyway, here some reads from Perl Cookbook : 16.11. Making a Process Look Like a File with

Re: Concurrency

it safe to say that the Thread.pm module will be a safe and portable way to do concurrency in future versions of perl? Right now I am using the activestate perl which won't let me use threads because of ithreads or something. Basically I want this to run well on my windows and my linux syst

Re: Concurrency

Yep, using fork() will make your code less portable. If you want concurrency and don't want to use fork(), you'll need to either experiment with threads (as suggested by Jos), or build a multiplexed server using select(). One book I've found useful is Network Programming with Pe

Concurrency

would be the best way to be able to both accept and initiate network connections in perl? I want it to be portable. I assume some kind of concurrency would be needed but then again I havce only been using perl for a week. Thanks, Ryan
