Hello,

I have a few questions regarding Unix standards. I would like to know
where I can obtain the X/Open Portability Guide (XPG3). Is it free of
charge? Is it outdated? I read about it in Stevens' book about
programming in the unix environment. I tried following some
links from http://www.opengroup.org/ but it seems that this
document is no longer available.

Thanks,

Neil

Did you get as far as:
http://www.opengroup.org/publications/catalog/un.htm

I think that only goes as far back as XPG/4 though. However, why do
you want XPG/3 - why not just go look at SUSv3:

It seems as though the IEEE 1003.1-2001 AKA ISO/IEC 9945-1,2,3,4-2002
replace not only the old POSIX.1 standard but also the XPG guides and
the Unix95 standard. Is this correct?

Furthermore, how come there is no posix threads standards (POSIX.4)
at http://webstore.ansi.org/ ?

What is SUSv3? The last link points to IEEE 1003.1
(i.e., the newest POSIX.1 standard).

Thanks,

Neil

Yes. UNIX95 is the same as SUSv1 - UNIX98 is SUSv2.

Because ANSI != POSIX.

SUSv3 is the latest version of the Single UNIX Specification.
It's a joining of POSIX and SUSv2. Before, POSIX and SUS were
two different documents (with a lot of overlap). Now, they are
one and the same document. This is all documented on www.opengroup.org.
