pipe(2)
write(2)
read(2)
socket(2)
bind(2)
accept(2)
connect(2)
(and a lot more, this will not tell much about how to use)
pipes can be used for interprossess communication on the same machine.
they must be initiatet from the same program:
lyx -> setup pipes -> fork -> exec(ispell)
named pipes
lyx -> setup named pipe (file "lyxin" or whatever is created)
foobar -> connect to (open) "lyxin"
unix sockets (sockets used that is similar to namedpipes)
lyx -> setup unix socket. "lyxsocket"
foo -> connect to "lyxsocket"; lyx spawns new lyxserver that talks with foo
bar -> connect to "lyxsocket"; lyx spawns new lyxserver that talks with bar
ip sockets similar to unix socket, but can be used from remote. (I
don't think we want that.)

But the server will never know which of the it speaks too. And all the
clients connecting will work on the same buffer.
