Henry Spencer said that "there have already been two releases of the SVID". This was denied by someone whose name I forget, posting from AT&T. I pointed out that Henry Spencer is correct according to the SVID itself. I never claimed that this was a bad thing. My word, I _like_ the Future Directions sections in the SVID, and wish more O/S vendors did that. I don't know whether you'd count the behaviour of getcwd() when passed a NULL argument as useful; but it is documented V.2 functionality which I have known programs to use and it was dropped in SVID 2. There are a couple of other documented changes worth noting, and then there are the differences they didn't notice. (Find them yourself.) >> As I have found to my cost, Issue 2 is not always a reliable guide to V.3. >What things are not accurate? To say that SVID 2 is not a reliable guide to V.3 is not to say that anything in it is inaccurate. SVID 2 claims only to describe V.1 and V.2. If you really want to know about the differences between SVID 2 and V.3, read the V.3 release notes. The changes aren't just additions & enhancements. The lesson is: never assume that code which worked in release X.Y will work in release X.Y+1, always read the release notes *first*. Can I please get out of this topic now? I'm sorry I ever stepped in.
