I'm working on large program that I want to be as portable as
possible.  Although it is mainly aimed at Unix boxes I thought I'd
throw caution to the wind and write it using the emerging standards:
POSIX and ANSI C.

The first problem is how do I get ahold of the POSIX spec' in the UK?
Although I've heard a lot of discussion about POSIX and seen some
libraries that a POSIX compatiable (Doug Gwyn's directory scanning
code for example) I don't recall seeing the name of a book, or whatever,
detailing POSIX.

ANSI C is easier to get ahold of details.  I just bought the 2nd edition
of K&R.  It seems to be a good general guide, but stddef.h, errno.h and
locale.h don't seem to be documented anywhere.

I'd really like pointers to official publications detailing POSIX and ANSI C.
If anyone knows how to get them in the UK I'd be very grateful.

While I'm asking I'd like public or freely available implementation of
POSIX or ANSI C libraries so that I can port to a wider range of systems.
So far I've only Doug Gwyn's directory stuff and a couple of
programs for converting ANSI C to K&R C (ansi2kr an agcp).  Any other
contributions would be greatly appreciated.

	thanx in advance

The people to contact about both POSIX and ANSI C in this country are
the BSI.  There is likely to be another ISO Draft Proposal on ANSI C,
with a corresponding BSI DP, and that is a good opportunity to get a
copy of the current draft.  POSIX I am less in touch with.  I am not sure
of the best address to contact in the BSI, and it is a somewhat rambling
organisation (several locations in London, Milton Keynes etc.)  Try
chasing up via one of the London locations.

WARNING:  do NOT rely on the second edition of K&R.  They 'jumped the
gun' and predicted the future wrong; I believe that they are working on
a corrected second edition.  I would also suggest working from the real
standard, unless K&R second edition is considerably more thorough than
the first edition.
