That note against using useconds_t if portability is important was
probably true before POSIX, but since POSIX specifies the type in
<sys/types.h>, as recently documented in useconds_t(3), the type
should be fine to use portably. Moreover, using it helps document
the code, so we better completely remove that warning.
Add a SEE ALSO entry for useconds_t(3).

sockaddr-struct.3, timespec-struct.3, timeval-struct.3: Rename some links to system_data_types.7 to add -{struct,union} suffix
This avoids shadowing other pages, and clearly differentiates
function pages from type pages (both are in man3).
Do this for struct/union types, and not for typedefs. This makes
sense because typedefs in C are in the same namespace as function
identifiers, but struct and union (and enum) tags are in a
different one, and can have the same name as a function.

While perusing various termios(3) and termios(4) manpages, I
noticed the following inconsistency for ONLRET. FreeBSD and
NetBSD say this:
If ONLRET is set, the NL character is assumed to do the
carriage-return function; the column pointer will be set to 0.
OpenBSD says this:
If ONLRET is set, NL also performs CR on output, and reset
current column to 0.
POSIX says this:
NL performs CR function.
The current Linux manpage says this (!):
Don't output CR.
Here's a snippet that demonstrates Linux's behavior (tl;dr it's
just like the other operating systems):
$ stty -icanon -onlcr -icrnl -echo onlret onocr; cat
this is some text (^J pressed)
and some more (^M pressed before additional text)
The first flags (-icanon -onlcr -icrnl -echo), combined with cat,
ensure that our keys are sent directly back to the terminal
emulator without any translation or buffering. The last two
(ONLRET and ONOCR) are the important ones: ONLRET makes Linux
think that the cursor is at column 0 after the ^J, and ONOCR makes
Linux ignore the following ^M.

Clarify that the pthread_atfork() callback list is a global, not
per-thread.
The use of "this thread" implied to some readers that pthread_atfork()
maintained per-thread lists of callbacks. Given that the next sentence
already explains that the callbacks are run in the context of the thread
that calls fork(), I actually think it would be fine not to mention
threads at all in the earlier sentence, but for now I've gone with what
I think was intended to be written.
This patch also attempts to clarify other references to "thread",
and fixes a trivial typo "form" instead of "fork".

Use the following order:
- Success
- Over/Underflow
- Special cases specified by the standard (in the same order)
- Other special cases not specified by the standard.
This way it's easier to compare this document against the standard
to check for any mistakes or differences.
I also added a comment at the beginning of each case, to more
clearly delimit special cases, with a syntax that is easy to read
(a mix of C, mathematical language, ...). We may want to use

str[n]dupa() are available on every modern compiler platform,
incl. Clang, ICC, &c.
By shortening the third paragraph, it now reads
strdupa() and strndupa() are similar,
but use alloca(3) to allocate the buffer.
pointing squarely to alloca(3), which is scary enough,
so drop the extraneous warning, too ‒ this clearly points to
"see alloca(3) for the limitations of that allocator".
Plus, it's not like malloc(3) doesn't have its problems, too,
but I don't see those being touted in the first paragraph;
reducing these to the bare minimum,
strdup() copies into malloc(3) and you can free it with free(3),
strndup() likewise, but up to n, and
str[n]dupa() use alloca(3) instead ‒ be wary of what alloca(3) does!
doesn't really make sense ‒ it's obvious that, ex definitione,
alloca(3) suffers from alloca(3) problems and input limits,
just like malloc(3) from the malloc(3) suite's.

I agree that there's a problem, but I think we could go even simpler:
rc = pthread_getname_np(thread, thread_name, NAMELEN);

I imagine that the author's intention was to allow the user to do
experiments where argv[2] specified a number less than NAMELEN,
in order to see the resulting ERANGE error. But, that experiment
is of limited value, and complicates the code unnecessarily, IMO,
so that's why I made the change above.

Explain that `optstring` cannot contain a semi-colon (`;`)
character.
[mtk: verified with a small test program; see also posix/getopt.c
in the glibc sources:
if (temp == NULL || c == ':' || c == ';')
{
if (print_errors)
fprintf (stderr, _("%s: invalid option -- '%c'\n"), argv[0], c);
d->optopt = c;
return '?';
}
]
Also explain that `optstring` can include `+` as an option
character, possibly in addition to that character being used as
the first character in `optstring` to denote `POSIXLY_CORRECT`
behaviour.
[mtk: verified with a small test program.]
Test program below. Example runs:
$ ./a.out -+
opt = 43 (+); optind = 2
Got plus
$ ./a.out -';'
./a.out: invalid option -- ';'
opt = 63 (?); optind = 2; optopt = 59 (;)
Unrecognized option (-;)
Usage: ./a.out [-p arg] [-x]

SPARC is special, it does not have Bnnn constants for baud rates above
2000000. Instead it defines 4 Bnnn constants with smaller baud rates.
This difference between SPARC and non-SPARC architectures is present in

No implementation or spec requires *n to be 0 to allocate a new buffer:
* musl checks for !*lineptr
(and sets *n=0 for later allocations)
* glibc checks for !*lineptr || !*n
(but only because it allocates early)
* NetBSD checks for !*lineptr
(and sets *n=0 for later allocations)
(but specifies *n => mlen(*lineptr) >= *n as a precondition,
to which this appears to be an exception)
* FreeBSD checks for !*lineptr and sets *n=0
(and specifies !*lineptr as sufficient)
* Lastly, POSIX.1-2017 specifies:
> If *n is non-zero, the application shall ensure that *lineptr
> either points to an object of size at least *n bytes,
> or is a null pointer.
The new wording matches POSIX, even if it arrives at the point slightly
differently

See <bits/byteswap.h> in glibc.
These macros call functions of the form __bswap_N(),
which use uintN_t.
Even though it's true that they are macros,
it's transparent to the user.
The user will see their results casted to unsigned types
after the conversion due to the underlying functions,
so it's better to document these as the underlying functions,
specifying the types.

In b0b19983d9a2001ce94b908a99f4c05a50fd47ee we removed
<sys/types.h>. For the same reasons there, remove now <sys/ipc.h>
from many pages.
If someone wonders why <sys/ipc.h> was needed, the reason was to
get all the definitions of IPC_* constants. However, that header
is now included by <sys/msg.h>, so it's not needed anymore to
explicitly include it. Quoting POSIX: "In addition, the
<sys/msg.h> header shall include the <sys/ipc.h> header."
There were some remaining cases where I forgot to remove
<sys/types.h>; remove them now too.

ENODATA is an XSI STREAMS extension (not base POSIX).

The current manual pages don't use ENODATA with its POSIX
