[comp.unix.wizards] socket questions

rich@oxtrap.UUCP (07/08/87)

Please forgive me,  these questions MUST have been discussed already
but I haven't been on the net regularly in over a year.

1. How big is a socket?
1.1 What is the largest message I can send on a datagram?
	(I presume this is domain dependent)
1.2 How much data can a writer write, (assume reader is asleep),
	before writer blocks (or returns error)?
2. Why aren't datagrams reliable in the UNIX domain?
	I can understand the overhead across a network of gaurenteeing
	this reliability and I've forced them to fail in the unix
	domain, but why?

I'm currently on a 4.2 port, (Sequent).
