No shared memory, no semaphores - (currently) true. No IPC, no messages - go forth and read: SOCKET(2) BIND(2) LISTEN(2) ACCEPT(2) CONNECT(2) SEND(2) RECV(2) in your 4.2BSD manuals, then try again. (Unlike those in a certain famous USDL-developed system, they work over a network. Wait a minnit, somebody's saying they don't work over a network because nothing other than file transfer and remote command execution works over a network in that system. Gee.... No!) No locks - no record locks, but for file locks, go forth and read: FLOCK(2) and try again. Moral: flaming about the general unworthiness of some UNIX system other than your favorite generally causes singed eyebrows and little illumination. (This goes for you Berkeleyphiles - and even Researchphiles - out there, too.) Guy Harris
