man/man2/*: Update history of syscalls CI-G

Hello,

This patch set updates the POSIX/SUS history of system calls with identifiers starting with CI through G. It also attempts to provide chronological order where possible, similar to the last patch set.

Although this set does begin to touch on man pages with a peculiar listing in their HISTORY sections. Namely, "4.4BSD (first appeared in 4.2BSD)". I ordered these as if they were just "4.4BSD", since that's not inside the brackets and so should be more important (otherwise I'd assume it'd just say "4.2BSD" instead). Although I'm not confident in this choice, so any thoughts regarding this would be appreciated.

2.47.3

clock_getres(2), clock_gettime(2), and clock_settime(2) first appeared in POSIX.1-1996.[1] SUSv2 incorporates POSIX.1-1996, so listing both is redundant.

Hi Seth,

Are you sure SUSv2 incorporates POSIX.1-1996? Could you please show sources for that?

Cheers,
Alex

<https://www.alejandro-colomar.es>

Hi Alex,

We can reference the following SUSv2 PDF:
CAE Specification, System Interfaces and Headers, Issue 5.
<https://pubs.opengroup.org/onlinepubs/009639399/toc.pdf>

Section 1.6 "Relationship to Formal Standards", page 11 states:

Great care has been taken to ensure that this specification is fully aligned with the following formal standards:
- ISO/IEC 9945-1:1996
- ISO/IEC 9945-2:1993
- ISO/IEC 9899:1990
- ISO/IEC 9899:1990/Amendment 1:1994 (E) (MSE)
- Federal Information Procurement Standards (FIPS) 151-2.

Any conflict between this specification and any of these standards is unintentional.

Additionally, section 1.7 "Portability", page 12 states:

This document describes a superset of the requirements of the ISO POSIX-1 standard and the ISO C standard. [...] (The ISO POSIX-1 standard is identical to IEEE Std 1003.1-1996, which is often referred to as the POSIX.1 standard. [...])

For context, page xiii defines "ISO C" as ISO/IEC 9899:1990 including Technical Corrigendum 1:1994 and Amendment 1:1994. And "ISO POSIX-1" as ISO/IEC 9945-1:1996.

So SUSv2 XSH is a superset of POSIX.1-1996 and C95.

Take care,
	Seth McDonald.

Hi Seth,

Thanks! And then I guess POSIX.1-1996 would also be based on C95. This is quite interesting!

Have a lovely night!

Hi Seth,

I'd replace such a thing by 4.2BSD, as you suggest.

Cheers,
Alex

<https://www.alejandro-colomar.es>

Hi again,

v2 now treats listings of both 4.2BSD and 4.4BSD as equivalent to just 4.2BSD, and thus removes the redundant mention of 4.4BSD in such cases.

2.47.3

clock_getres(2), clock_gettime(2), and clock_settime(2) first appeared in POSIX.1-1996.[1] SUSv2 incorporates POSIX.1-1996, so listing both is redundant.

2.47.3

Technically these functions came from POSIX.1b (1003.1b-1993), which was a set of optional realtime extensions to POSIX, published as a separate document. POSIX.1-1996 integrated them into the main standard (1003.1-1996) as part of a Timers extension. In 1997 X/Open adopted them to SUSv2 as part of their own X/Open Realtime extension, which includes the POSIX Timers extension and other extensions that had been added to POSIX from POSIX.1b.

Hi Mark, Seth,

Thanks! For now, I think I'll take the patch, even if the commit message is factually incorrect. We can then do a future round of patches researching those less common POSIX extension standard.

Does this sound good?

Have a lovely day!
Alex

<https://www.alejandro-colomar.es>

Sounds great!

- Mark

Hi Alex and Mark,

Good to know. I'll be sure to phrase my patch descriptions more carefully from now on to prevent such inaccuracies.

Take care,
	Seth McDonald.
