[PATCH v1 00/12] man/man{2,3}const/*: Update POSIX history of constants

[PATCH v1 00/12] man/man{2,3}const/*: Update POSIX history of constants

[Seth McDonald]

Hello all,

I'm continuing to update the first POSIX and SUS appearances of various
system calls and functions, but I'm doubting that it's a good idea to
wait and send all patches in at once.  So while I continue, I'll try
grouping related updates into patch sets and sending them through
semi-regularly.

To start, this patch set consists of updates for documented constants
in the 2const and 3const sections.  I've provided a reference to the
relevant POSIX version for each patch, providing links where possible.

In general, each patch concerns a separate page.  However, if two pages
share similar names and are referenced in the same section of POSIX
(such that the citation given for both are the same), then I batched
them together into the same patch.

Also perhaps noteworthy: if updating a page required only adding a POSIX
or SUS version, I usually added it in a new line and left any other
listed standards untouched.  While if it required changing a line shared
with other standards, I typically reformatted it to list each standard
on a separate line (for nicer diffs with future changes).

What ordering is used for these?

4.3BSD was 1986.[1]

POSIX.1-1988 was, nominally, 1988 but we all know how standards
sometimes lag.  It seems the record is murky in this case.[2]

I've seen dates of 1988 applied SVr4, but no reports that it was
publicly available until 1989.[3]

Branden

Ideally, I would like it to be in chronologic order.

If anyone wants to do research and improve those --as Seth is doing--,
I'll welcome patches.  :)


Have a lovely New Year!
