Some OS like MACH use a copy-on-write policy so that if 2 processes fork it will just duplicate memory-pages which are different between the processes, but standard UNIX doesn't do that. And there is no share_memory() function that I know of. > > Starting new processes is ok if you use threads, but might give > > you horrible synchronisation problems the way circle is written. > And how do you use threads? If you are running on a SUN try: 'man thr_create' If you are running on MACH try: 'man cthread_detach' If you are running Linux - no idea if it implements threads but just a warning: don't dare to access any global variable like buf, buf1, world ... with a thread without using mutex variables ... !!!!!
