[net.wanted] Help wanted with 4.2BSD sockets

randy@utcsrgv.UUCP (Randall S. Becker) (05/20/84)

	I am trying to figure out how to use the IPC facility on
	4.2BSD. Does anyone out there have a sample program which
	actually runs? I have read the man entries and online 
	ipc documentation (which is [I think] usually included in
	4.2BSD distribution). My main problem is that `accept' is
	not blocking my server. The documentation states that normally
	it should block unless told otherwise. It does not mention 
	(at least I have not noticed) the technique for configuring
	or reconfiguring a socket for either blocking of non-blocking
	mode. I gather that this is done via `setsockopt' ; but the 
	documentation is severely poor for that routine. Any help 
	would be appreciated. By the way, I am not overly concerned
	with net-sockets; just simple local client/server sockets.

		Thanks in advance,

I'm not looking at the manual right this instant, but if I remember
correctly, you must first bind() your socket to an address before
you can use it for anything.  Do a perror()  and check the man entry.
