Does vanilla System V/386 3.2 provide *ANY* mechanism that I can use to emulate Unix domain sockets and select(2)? I am writing a server program that needs to communicate with many clients. On BSD, my server can create a Unix-domain socket, bind(2) a name to it (something like $HOME/.my_server), and then all the clients can use connect(2). My server is nice and simple because I can use select(2) to multiplex the clients AND new connection requests. The System V function poll(2) looks like it would make a nice substitute for select(2), even though the timeout granularity is in seconds instead of microseconds. I'd willing to take what I can get. However, what STREAMS devices do I have at my disposal? Are stdin, stderr, and stdout STREAMS devices? Are pipes STREAMS devices? What about named pipes? I've seem mention in this newsgroup of the undocumented device /dev/spx, which is a "stream pipe", but it seems that /dev/spx comes with RFS, and I do not have RFS installed (I *WILL* install it if someone can show me how to use /dev/spx to emulate sockets). I already know about the standard System V IPC mechanisms: message queues, semaphores, and shared memory. These won't do: I want a file descriptor. Am I going to have to break down and buy an Ethernet card and Lachman TCP/IP ? :-( :-( -- Scott Weitzenkamp UUCP: uunet!talarian!scott Talarian Corporation ARPA: scott@talarian.uu.net "Welcome to the late show, starring NULL and void" -- Men At Work Mail responses, and I'll summarize to the net.
