Is this possible using Ethernet? If so, then how? Dumps: see rdump(8) and rrestore(8). I've been using them for a long time now and they work nicely. Program output: Not possible transparently, as far as I know. --- <decwrl!amdcad!amdimage!prls!philabs!cmcl2!rna!dan> asks: > Has anyone used the System V-style shared memory facility in >Ultrix-32m (Microvax II) ... >For example, what role does "key" >play ? How do I pass the shared memory segment to non-related process ? Yes. Works nicely. See ipcs(1) and the transitive closure of its SEE ALSO sections. Also look at ftok(3c) to discover the mysteries of the 'key'. -- Ollie Jones DEC High Performance Workstations jones@3d.dec 617-480-6651 Disclaimer: If I (or anyone I've ever met) claimed to represent the opinions of my employer, they'd be making a false claim.
