[PATCH v1 00/25] man/man3type/*: Update history of all other types

[PATCH v1 00/25] man/man3type/*: Update history of all other types

[Seth McDonald]

G'day,

This patch set should account for all other man-page entries in the
3type section whose listed first POSIX/SUS appearance can be updated.
As per Alex's request, any added POSIX/SUS versions are listed in
chronological order with respect to any other listed standards.

I did make one "exception" though, regarding types that appeared in both
C89 and POSIX.1-1988.  Despite POSIX.1-1988 being published before C89,
many (if not all) such types were included in POSIX.1-1988 primarily for
compatibility with the then-upcoming C standard (i.e. C89).  So it is
likely more chronologically accurate to list C89 before POSIX.1-1988 in
these cases.

[Seth McDonald]

From: Seth McDonald <sethmcmail@pm.me>

id_t(3type) first appeared in SUSv1.[1]  The type was added to
POSIX.1-2001 when POSIX and SUS merged, but as an XSI extension (still
SUS-only).[2]  Then POSIX.1-2008 moved it to the base specification.[3]

intptr_t(3type) and uintptr_t(3type) first appeared in SUSv2.[1]  The
types were added to POSIX.1-2001 when POSIX and SUS merged, but are only
mandatory on XSI-conformant systems.[2]

[PATCH v1 05/25] man/man3type/intptr_t.3type: HISTORY: Update first POSIX appearance of [U]INTPTR_MAX and INTPTR_MIN

[Seth McDonald]

From: Seth McDonald <sethmcmail@pm.me>

INTPTR_MAX, UINTPTR_MAX, and INTPTR_MIN are defined if and only if
intptr_t(3type) and uintptr_t(3type) are declared.[1]  So given that the
types are only mandatory on XSI-conformant systems, the same is true for
the macros.

I think 'void*' is important enough that it would be useful to dig in
its history further.  Was it an invention of C89?  Or was it an
extension in some existing compilers?  If the latter, it would be
interesting to document which systems had it before C89.

I'm mentioning this just in case you know.  Feel free to ignore
otherwise.

Anyway, I've applied the patch.  Thanks!


Have a lovely day!
Alex

I know that the void pointer type was not mentioned or used in
POSIX.1-1988.  Instead, the standard used the char pointer type for
pointers to generic data.  POSIX.1-1990 seems to implicitly require void
pointers - at least for conformance to "POSIX.1, C Language Binding (C
Standard Language-Dependent System Support)" - by including them in some
function prototypes.

Looking at C89, it did explicitly specify void pointers as part of the
language, stating that "[a] pointer to void shall have the same
representation and alignment requirements as a pointer to a character
type."[1]

Looking* at K&R C, I skimmed through chapter 5 "Pointers and Arrays",
and couldn't find any references to void pointers.  In fact, it seems to
use char pointers instead, similar to POSIX.1-1988.

So I think what happened (pure speculation) was between 1978 and 1989,
void pointers increased in user popularity and compiler support enough
that ANSI decided to extend the language by adding void pointers to its
1989 C standard.  Which would explain why POSIX.1-1988 also didn't have
void pointers, but POSIX.1-1990 suddenly did.

With regard to implementation support for void pointers prior to C89,
this is where my knowledge falls short.  I'm not the most educated on
past implementations (yet).

*I found this[2] PDF online which appears to be a scan of a (heavily
annotated) copy of the first edition of The C Programming Language.
I don't know if it's authentic though, so take it with a grain of salt.

Hmmm, since POSIX.1-1988 was already written after some C89 draft, it
seems void* was incorporated to C89 in a late draft.

Yup, K&R C 1st ed. is too old and I wouldn't expect it to have
void*.  I have a physical copy of K&R C 2nd ed. (1988) and it does have
void*.

That's fine.  If anyone else reading the list knows anything, it would
be welcome.

Being a scan, it could be authentic.  I don't have a physical copy of
the first edition, so can't compare.

Be careful of online copies of K&R C, though.  I once found one of the
second edition, and it was fake (by comparing it to the actual copy).

Much better to get the physical copy.  Although the first edition seems
difficult to find.

I have a physical copy of K&R 1e, but unfortunately it is in storage and
not easy to access.  However...

I have before me as I type this a copy of Tom Plum's _Notes on the Draft
C Standard_, copyright 1987 (Plum Hall, ISBN 609-927-3770).  Publishers
treat years in copyright notices the way automakers treat them in
vehicle models, so I'd guess this puts the date of publication anywhere
from 4Q1986 to 3Q1987.

In Chapter 2, "Comparison with Earlier C", on p. 24, it says:

	"A pointer to any object type may be converted to a ‘‘generic’’
	pointer and back again without change.  The syntax for generic
	pointer is void *."

Tom Plum was a noteworthy figure in C standardization circles; his name
shows up in much literature on the subject.  I'd regard him as an
authority.

Looks like he passed away last year.  :(

Thanks!

I've now checked the rationale for C89, and it says that

	Several new types have been added:

And mentions 'void', 'void*', and 'signed char'.  It seems it was an
invention of C89.

From evidence in the utzoo Usenet archive, the idea was around before
the ANSI C effort.

The first mention of "void *" is in November 1982, where Ken Dalka
(ihuxe!dalka) observed in net.lang.c that void * was accepted as a type.
He didn't say which compiler was being used, but an earlier post said
ihuxe "runs USG 4.0 UN*X".

The next is from Mary Ann Horton (mark@cbosgd.UUCP) in January 1984,
also in net.lang.c, who suggests using "(void *) 0" as a definition of
NULL, giving a varargs function with args terminated by NULL as an
example.

Then in March 1984, Doug Gwyn (gwyn@Brl-Vld.ARPA) says, as part of a
discussion about casting the result of malloc in net.unix-wizards:

> The C Language Standards Committee was talking about adding
> (void *) to the language as a generic pointer type.  Perhaps

It then shows up in various posts in both of those groups throughout
1984, including a summary by Henry Spencer in June 1984 of Larry
Rosler's presentation on the ANSI C project at Usenix saying:

Huh, would this be the "System IV" that was never externally released?
The year seems consistent with that.  Interesting!  According to
<https://www.tuhs.org/Archive/Documentation/Manuals/Unix_4.0/README>,
the official name of this would be PWB 4.0. or Unix/TS 4.0.

Should we document it as Unix/TS 4.0?

This predates the C Committee by one year, BTW.

It would also be useful to know when the BSD lineage incorporated void*.

I've recently learned that wchar_t and related APIs were introduced to
ISO C in C95.  If you are interested in them, you could check the C95
draft (there's a link in standards(7) --I added it a few weeks ago--).
Otherwise, I'll have a look at it myself.  Let me know.

I've applied the patch.  Thanks!

I can include this in later patches, as long as citing the draft is
sufficient justification.  I personally tend to have a more 'final
standard only' mindset, but if you're okay with the draft, then I'm
all good to use it.

For the 3type section I've already covered, it'd probably be easier if
you could patch up the few types that first appeared in C95.  I'd rather
not keep going back to refine previous patches, as I've found (from
general experience) this mindset tends to cause me to *constantly* find
new ways to polish what I've already done, preventing me from making
much progress.

For ISO C, unless you have the money to pay for the standard documents
(usually, this is only done by companies that need certification), the
drafts are the only available thing.  The actual standards are behing a
paywall, and most people never see one.  I have never seen an ISO C
standard (and I'm member of the C Committee).

The C Committee publishes drafts of what will become the standard, and
usually, it's enough to consult the draft that's closest to the
standard.  See also:
<https://stackoverflow.com/questions/81656/where-do-i-find-the-current-c-or-c-standard-documents>

For C95, the draft n412 is, as far as I understand, identical to the
standard (except for the ISO cover sheet, etc.).  Draft n412 was an
early draft for C99 published around the publication of C95, and even in
the SUMMARY of the draft, it states that "This document represents C90
with Technical Corrigendum 1 and Amendment 1 applied".  See
<https://www.open-std.org/jtc1/sc22/wg14/www/docs/n412.pdf>.

For C23, for example, the draft n3220 is identical to C23 except for one
typo in C23 that was fixed in n3220.  (n3220 is the first draft of C2y).

In other versions of ISO C, drafts may differ more from the actual
standard.

Yes, I'm taking your patches as they already improve the pages.  I was
mentioning this in case you want to write patches in the future that
also document C95.  FWIW, I've applied the patches already.
