This article is from the Threads Programming FAQ, by Bryan O'Sullivan email@example.com with numerous contributions by others.
To order ISO/IEC standard 9945-1:1996, which is also known as
ANSI/IEEE POSIX 1003.1-1995 (and includes 1003.1c, the part that deals
with threads), you can call +1-908-981-1393. The document reference
number in the IEEE publications catalogue is SH 94352-NYF, and the
price to US customers is $120 (shipping overseas costs extra).
Unless you are implementing a POSIX threads package, you should not
ever need to look at the POSIX threads standard. It is the last place
you should look if you wish to learn about threads!
Neither IEEE nor ISO makes standards available for free; please do not
ask whether the POSIX threads standard is available on the Web. It
