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.)
