hope this is an ok place to post this. as far as i can tell there are three ways to share memory between processes - using mmap, ipc shared mem or skip it using threads instead. is this right? basically i have a server process accepting many connections & i was using threads, however, it doesn't really make sense processes would probably be simpler with shared mem. i was going to use IPC but don't like building uncessesary dependancies (i.e. it's a kernel option). is mmap the best way to do this? why would you use ipc instead? . . . and finally (milking the assistance to the last) is there a really simple app using shared mem resources that anyone knows about so i can butcher it? thanks in advance. fergus To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
