I have managed to find direct links to the official standard and they

I am not sure if there are any official standards after n1336.pdf.
Perhaps there are or perhaps there aren't unless you pay for them. Let
me know if there are any for free use.

I have now found the official download link to "ISO/IEC 9899:2018".� The

N1256 (in your list) is the amalgamated C99 + TC1 + TC2 + TC3 document,
very nice.

I believe N1570 (not in your list) was the last draft of C11.

OK Thanks for informing about N1570. I have found the official download
link so the complete list is as follows:

<http://www.open-std.org/jtc1/sc22/wg14/www/docs/n2310.pdf>

<http://www.open-std.org/jtc1/sc22/wg14/www/docs/n1124.pdf>

Please let us know if anything else is missing from the list. The next
standard is 23xx and it won't be approved until 2023 at the latest
unless something drastic happens in the interim.

No, you've found links to publicly released drafts of the C standard.

N1124 consists of the C99 standard with the first two Technical
Corrigenda merged into it. It's not particularly useful given the
existence of N1256.

N1256 consists of the C99 standard with the three Technical Corrigenda
merged into it. It's arguably more useful than the C99 standard itself
(which costs money) -- but of course the C99 standard itself is
officially obsolete.

N1336 is a draft of C201x (later called C11), not useful if you have N1570.

N1570 is the most recent available draft of C11.

I haven't been able to find any public drafts of C17. After N1570,
there are a number of password protected PDFs that are about the same
size as the standard drafts. Presumably they're for internal use by the
committee.

N2310 appears to be the earliest draft of the upcoming C202x standard,
and N2956 is probably the latest. (C202x will probably be C2023.)

All actual C standards cost money.

As usual, Microsoft has a somewhat different definition from other
people...

"Open standard" usually means that the standard is /available/ to anyone
who wants it - but not necessarily for free. There are a great many
open standards that are only available for a fee, or if you join the
relevant group. "Open" in this context means that anyone can get the
standards - there are no restrictions by country, company, contract,
etc. This also applies to the C and C++ standards, which are published
by ISO - anyone can get the standards, but you have to pay for them.
What is unusual (but /very/ nice) is that the ISO working groups here
publish their drafts at zero cost.

I have N2176, which is AFAIK the last public draft of C17 (it is titled
"C17 ballot").

Usually, the difference between the latest draft and the official
standard is essentially just some added frontmatter pages. C17 was an
exception, as AFAIK ISO actually made some changes within the standard
document (nothing big, but they moved a comma here and there, which made
the official standard worse than the latest draft, as these commata had
been deliberately placed the way they were in the draft by WG14 to make
the wording unambiguous).

Note that something being directly available for download, even if it's
hosted at the IP owners' own servers, doesn't make it somehow automatically
legal to download if the documents are under a commercial license.
Making something available without technical barriers is not in itself
any sort of implicit free license.

(I don't know if those documents are commercial. Merely pointing out
that fact.)

I understand that the WG14 / ISO copyright situation can be somewhat
complicated (and in the past ISO expressed some dislike about the
existance of that WG14 website). On the other hand, what you write would
hold for any text, website, etc, which is kind of impractical (how do I
know then I am allowed to read your message that I'm replying to here?).

Anyway, those N documents are not meant to be hidden by WG14. There is a
list of them
(http://www.open-std.org/jtc1/sc22/wg14/www/wg14_document_log.htm),
which is linked from the WB14 website
(http://www.open-std.org/jtc1/sc22/wg14/).
AFAIK, it is disputed who own the copyright to the individual N
documents there, and it might even differ by legislation (in particular
there might be US vs. EU law differences).

My copy is not protected at all. (Unsurprisingly, the sha1sum is
different from yours.) I don't remember where I got it, as it was in
October 2019 - but I am reasonably confident it was from an official
source (such as the wg14 web pages). Maybe they changed their policies
at some point.

I am not a lawyer :-), but these papers are not official ISO documents,
so no commercial license.

Especially humorous is n1256. ISO official documents are the C99
official standard, plus three separate corrigenda - TC1, TC2, and TC3.
ISO never published a "corrected" standard, just these four separate
documents.

In preparation for the C11 work, the committee then produced a "working
draft" with the TCs applied to the C99 standard. You need to have a base
document, right? And arguably a lot better than the official one, as the
bugs have been removed.

However, ISO never published this intermediate version, only the
completed C11 standard.
