Isn't there a shared memory module for Win32 ? That and a semaphore should cover it. I know Amine had Win32::MamMap (Jenda's site) - someone should get the source or re-write it for the masses. Barring that, the threads package should handle it if disk is too slow. > -----Original Message----- > From: Chuck Lee [mailto:[EMAIL PROTECTED] > Sent: Tuesday, July 29, 2003 10:53 AM > To: [EMAIL PROTECTED] > Subject: RE: Processes and hash references > > > <snip> > >>Another alternative is using threads, but they are only available in Perl >>5.8, so I'm not sure if you will have them available.
