Richard Magill) Distribution: world Organization: OTP, Ann Arbor Lines: 21 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). K. Richard Magill just guessing... fmsrl7!oxtrap!rich@eecae.ARPA ihnp4!mibte!fmsrl7!oxtrap!rich cbosgd!hal!oxtrap!rich decvax!cwruecmp!hal!oxtrap!rich
