New and rewritten pages
-----------------------
close_range.2
Stephen Kitt, Michael Kerrisk [Christian Brauner]
New page documenting close_range(2)
process_madvise.2
Suren Baghdasaryan, Minchan Kim [Michal Hocko, Alejandro Colomar,
Michael Kerrisk]
Document process_madvise(2)
fileno.3
Michael Kerrisk
Split fileno(3) content out of ferror(3) into new page
fileno(3) differs from the other functions in various ways.
For example, it is governed by different standards,
and can set 'errno'. Conversely, the other functions
are about examining the status of a stream, while
fileno(3) simply obtains the underlying file descriptor.
Furthermore, splitting this function out allows
for some cleaner upcoming changes in ferror(3).
Newly documented interfaces in existing pages
---------------------------------------------
epoll_wait.2
Willem de Bruijn [Dmitry V. Levin]
Add documentation of epoll_pwait2()
Expand the epoll_wait() page with epoll_pwait2(), an epoll_wait()
variant that takes a struct timespec to enable nanosecond
resolution timeout.
fanotify_init.2
fanotify.7
Jan Kara [Steve Grubb]
Document FAN_AUDIT flag and FAN_ENABLE_AUDIT
madvise.2
Michael Kerrisk
Add descriptions of MADV_COLD and MADV_PAGEOUT
Taken from process_madvise(2).
openat2.2
Jens Axboe
Add RESOLVE_CACHED
prctl.2
Gabriel Krisman Bertazi
Document Syscall User Dispatch
mallinfo.3
Michael Kerrisk
Document mallinfo2() and note that mallinfo() is deprecated
Document the mallinfo2() function added in glibc 2.33.
Update example program to use mallinfo2()

epoll_pwait2.2
Dmitry V. Levin
New link to epoll_wait(2)
mallinfo2.3
Michael Kerrisk
New link to mallinfo(3)
off64_t.3
Alejandro Colomar
New link to system_data_types(7)
Global changes
--------------
Various pages
Alejandro Colomar
SYNOPSIS: Use 'restrict' in prototypes
This change has been completed for *all* relevant pages
(around 135 pages in total).
Various pages
Alejandro Colomar [Zack Weinberg]
Remove unused <sys/types.h>
The manual pages are already inconsistent in which headers need
to be included. Right now, not all of the types used by a
function have their required header included in the SYNOPSIS.
If we were to add the headers required by all of the types used by
functions, the SYNOPSIS would grow too much. Not only it would
grow too much, but the information there would be less precise.
Having system_data_types(7) document each type with all the
information about required includes is much more precise, and the
info is centralized so that it's much easier to maintain.
So let's document only the include required for the function
prototype, and also the ones required for the macros needed to
call the function.
<sys/types.h> only defines types, not functions or constants, so
it doesn't belong to man[23] (function) pages at all.
I ignore if some old systems had headers that required you to
include <sys/types.h> *before* them (incomplete headers), but if
so, those implementations would be broken, and those headers
should probably provide some kind of warning. I hope this is not
the case.
[mtk: Already in 2001, POSIX.1 removed the requirement to
include <sys/types.h> for many APIs, so this patch seems
well past due.]
A few pages
Alejandro Colomar
Add notes about missing glibc wrappers
_exit.2
abort.3
err.3
exit.3
pthread_exit.3
setjmp.3
Alejandro Colomar
SYNOPSIS: Use 'noreturn' in prototypes
Use standard C11 'noreturn' in these manual page for
functions that do not return.
Various pages
Ganimedes Colomar [Alejandro Colomar]
Normalize SYNOPSIS notes about nonexistent glibc wrappers
To easily distinguish documentation about glibc wrappers from
documentation about kernel syscalls, let's have a normalized
'Note' in the SYNOPSIS, and a further explanation in the page body
(NOTES in most of them), as already happened in many (but not all)
of the manual pages for syscalls without a wrapper. Furthermore,
let's normalize the messages, following membarrier.2 (because it's
already quite extended), so that it's easy to use grep to find
those pages.
Normalize NOTES about nonexistent glibc wrappers
This commit normalizes texts under sections other than SYNOPSIS
(most of them in NOTES).
Global changes (formatting fixes and minor edits)
-------------------------------------------------
Various pages
Michael Kerrisk
ERRORS: remove redundant statement that 'errno' is set
This is implied in every other manual page. There is no need to
state it explicitly in these pages.
Various pages
Michael Kerrisk
Use periods more consistently inside code comments
In general, complete sentences in free-standing comments
should be terminated by periods.
A few pages
Michael Kerrisk
Better table formatting
In particular, allow for rendering in widths different from
(especially less than) 80 columns.
Various pages
Michael Kerrisk
Consistency fix-up in FTMs
Generally, place '||' at start of a line, rather than the end of
the previous line.
Rationale: this placement clearly indicates that that each piece
is an alternative.
Various pages
Michael Kerrisk [Alejandro Colomar]
Bring more whitespace consistency in SYNOPSIS
The use of vertical white space in the SYNOPSIS sections
is rather inconsistent. Make it more consistent, subject to the
following heuristics:
* Prefer no blank lines between function signatures by default.
* Where many functions are defined in the SYNOPSIS, add blank
lines where needed to improve readability, possibly by using
blank lines to separate logical groups of functions.
Various pages
Alejandro Colomar
Consistently use 'unsigned int'
Most pages use 'unsigned int' (and the kernel too).
Make them all do so.
Various pages
Michael Kerrisk
Various improvements in wording in RETURN VALUE
Various pages
Michael Kerrisk
s/Glibc versions </Glibc </ in Feature Test Macro discussions
Use a more compact notation that will render less wide
on the terminal.
Various pages
Michael Kerrisk
Standardize wording around setting of 'errno' on error
In the RETURN VALUE sections, a number of different wordings
are used in to describe the fact that 'errno' is set on error.
There's no reason for the difference in wordings, since the same
thing is being described in each case. Switch to a standard
wording that is the same as FreeBSD and similar to the wording
used in POSIX.1.
In this change, "to indicate the cause of the error"
is changed to "to indicate the error".
Various pages
Michael Kerrisk
Add missing .nf/.fi in FTM info
Various pages
Michael Kerrisk
Simplify mark-up for Feature Test Macro requirements
Different source styles are used in different pages to achieve the
same formatted output, and in some cases the source mark-up is a
rather convoluted combination of .RS/.RE/.TP/.PD macros. Simplify
this greatly, and unify all of the pages to use more or less the
same source code style. This makes the source code rather easier
to read, and may simplify future scripted global changes.
The feature test macro info is currently bracketed by .nf/.fi
pairs. This is not strictly necessary (i.e., it makes no
difference to the rendered output), but for the moment we keep
these "brackets" in case they may be replaced with something else.
Various pages
Michael Kerrisk
Use real minus signs in pathnames
Various pages
Michael Kerrisk
Standardize wording around setting of 'errno' on error
In the RETURN VALUE sections, a number of different wordings
are used in to describe the fact that 'errno' is set on error.
There's no reason for the difference in wordings, since the same
thing is being described in each case. Switch to a standard
wording that is the same as FreeBSD and similar to the wording
used in POSIX.1.
In this change, reword various cases saying that 'errno' is set
"appropriately" to "is set to indicate the error".
Various pages
Michael Kerrisk
Improve formatting in ATTRIBUTES
Make the formatting more consistent inside the tables in the
ATTRIBUTES sections. Make the source code more uniform; in
particular, eliminate the use of custom tweaks using
'lbwNN'/'lwNN' and .br macros. In addition, ensure that
hyphenation and text justification do not occur inside the tables.
Various pages
Michael Kerrisk
Use .nf/.fi in SYNOPSIS
The majority of pages use .nf/.fi in SYNOPSIS, but there are
still many that don't and use .br to achieve newlines. Fix many
of those. This brings greater consistency to the pages, which
eases editing and may ease future scripted edits to the pages.
Various pages
Michael Kerrisk
Standardize wording around setting of 'errno' on error
In the RETURN VALUE sections, a number of different wordings
are used in to describe the fact that 'errno' is set on error.
There's no reason for the difference in wordings, since the same
thing is being described in each case. Switch to a standard
wording that is the same as FreeBSD and similar to the wording
used in POSIX.1.
In this change, miscellaneous descriptions of the setting
of 'errno' are reworded to the norm of "is set to indicate
the error".
Various pages
Michael Kerrisk
Use "\-" to generate real minus in circumstances where appropriate
Use \- for math formulas, pathnames, manual page cross references,
etc.
Various pages
Michael Kerrisk
Inside code blocks (.EX/.EE) use \- to get real minus signs
A real minus can be cut and pasted...
Various pages
Alejandro Colomar
Remove explicit blank lines, replacing them with .PP when appropriate
Various pages
Michael Kerrisk
Use internally consistent continuation indents in SYNOPSIS
In the SYNOPSIS, a long function prototype may need to be
continued over to the next line. The continuation line is
indented according to the following rules:
1. If there is a single such prototype that needs to be continued,
then align the continuation line so that when the page is
rendered on a fixed-width font device (e.g., on an xterm) the
continuation line starts just below the start of the argument
list in the line above. (Exception: the indentation may be
adjusted if necessary to prevent a very long continuation line
or a further continuation line where the function prototype is
very long.)
Thus:
int tcsetattr(int fd, int optional_actions,
const struct termios *termios_p);
2. But, where multiple functions in the SYNOPSIS require
continuation lines, and the function names have different
lengths, then align all continuation lines to start in the
same column. This provides a nicer rendering in PDF output
(because the SYNOPSIS uses a variable width font where
spaces render narrower than most characters).
Thus:
int getopt(int argc, char * const argv[],
const char *optstring);
int getopt_long(int argc, char * const argv[],
const char *optstring,
const struct option *longopts, int *longindex);
Various pages
Michael Kerrisk
Standardize wording around setting of 'errno' on error
In the RETURN VALUE sections, a number of different wordings
are used in to describe the fact that 'errno' is set on error.
There's no reason for the difference in wordings, since the same
thing is being described in each case. Switch to a standard
wording that is the same as FreeBSD and similar to the wording
used in POSIX.1.
In this change, fix some instances stating that 'errno' is set
"appropriately" to instead say "to indicate the error".
Various System V IPC pages
Michael Kerrisk
Improve wording describing RETURN VALUE and setting of 'errno'
Changes to individual pages
---------------------------
alloc_hugepages.2
Michael Kerrisk
CONFORMING TO: reword to reflect that these system calls are long gone
cacheflush.2
Alejandro Colomar
Update SYNOPSIS for glibc wrapper
Glibc uses 'void *' instead of 'char *'.
And the prototype is declared in <sys/cachectl.h>.
clone.2
Valentin Kettner
Fix types in clone_args
A file descriptor is an int so it should be stored through an int
pointer while parent_tid should have the same type as child_tid
which is pid_t pointer.
close.2
Michael Kerrisk
SEE ALSO: add close_range(2)
copy_file_range.2
Alejandro Colomar
Document glibc wrapper instead of kernel syscall
Glibc uses 'off64_t' instead of 'loff_t'.
delete_module.2
Alejandro Colomar
SYNOPSIS: Fix prototype parameter types
The Linux kernel uses 'unsigned int' instead of 'int' for the
'flags' parameter. As glibc provides no wrapper, use the same
type the kernel uses.
epoll_create.2
Michael Kerrisk
CONFORMING TO: mention that epoll_create1() is Linux-specific
epoll_wait.2
Michael Kerrisk
CONFORMING TO: mention that epoll_pwait() is Linux-specific
execve.2
Palmer Dabbelt
Correct the versions of Linux that don't have ARG_MAX argv/envp size
execveat.2
Alejandro Colomar
Fix prototype
It's been 6 years since execveat(2) was added to the kernel,
and there's still no glibc wrapper. Let's document the kernel
syscall prototype.
getcpu.2
Michael Kerrisk [Alejandro Colomar]
Rewrite page to describe glibc wrapper function
Since glibc 2.29, there is a wrapper for getcpu(2).
The wrapper has only 2 arguments, omitting the unused
third system call argument. Rework the manual page
to reflect this.
getgid.2
getuid.2
Michael Kerrisk
Note that these interfaces never modify 'errno'
See https://www.austingroupbugs.net/view.php?id=511
and the POSIX.1-2008 specifications of the interfaces.
gethostname.2
Michael Kerrisk
Update FTM requirements for gethostname()
getpagesize.2
getdtablesize.3
Michael Kerrisk
Update/correct FTM requirements
getrusage.2
Michael Kerrisk
Starting in 2.33, glibc no longer provides vtimes()
ioctl_tty.2
Michael Kerrisk
Reformat argument type information
The current mark-up renders poorly. To resolve this, move
the type information into a separate line.
ipc.2
Alejandro Colomar
Fix prototype parameter types
kcmp.2
Michael Kerrisk
Since Linux 5.12, kcmp() availability is unconditional
kcmp() is no longer dependent on CONFIG_CHECKPOINT_RESTORE.
keyctl.2
Alejandro Colomar
SYNOPSIS: Fix prototype parameter types
The Linux kernel uses 'unsigned long'.
There's no reason to use the typedef '__kernel_ulong_t'.
lookup_dcookie.2
Alejandro Colomar
Use standard types: u64 -> uint64_t
madvise.2
Michael Kerrisk
SEE ALSO: add process_madvise(2)
mlock.2
Alejandro Colomar
mlock2(): Fix prototype parameter types
The documented prototype for mlock2() was a mix of the
glibc wrapper prototype and the kernel syscall prototype.
Let's document the glibc wrapper prototype, which is shown below.
Michael Kerrisk
CONFORMING TO: note more explicitly which APIs are in the standards
mmap2.2
Alejandro Colomar
Fix prototype parameter types
There are many slightly different prototypes for this syscall,
but none of them is like the documented one.
Of all the different prototypes,
let's document the asm-generic one.
mount.2
Michael Kerrisk
Note that the 'data' argument can be NULL
move_pages.2
Alejandro Colomar
Add notes about missing glibc wrappers
open.2
rename.2
Alyssa Ross
Refer to tmpfs rather than shmem
If I'm understanding correctly, tmpfs is a filesystem built on
shmem, so I think it's more correct (and probably much more
widely understandable) to refer to tmpfs here.
pciconfig_read.2
Alejandro Colomar
SYNOPSIS: Fix prototype parameter types
Use the glibc prototypes instead of the kernel ones.
Exception: use 'int' instead of 'enum'.
pidfd_open.2
Michael Kerrisk
Note the process_madvise(2) use case for PID file descriptors
readlink.2
Michael Kerrisk [Jonny Grant]
Emphasize that the returned buffer is not null-terminated
s390_pci_mmio_write.2
Alejandro Colomar
SYNOPSIS: Add 'const' qualifier
s390_pci_mmio_write() uses 'const void *' instead of 'void *'.
sched_setattr.2
Alejandro Colomar
Add note about missing glibc wrappers
semctl.2
Yang Xu [Alejandro Colomar, Manfred Spraul]
Correct SEM_STAT_ANY description
socketcall.2
Alejandro Colomar
Add note about missing glibc wrapper
splice.2
Alejandro Colomar
Use 'off64_t' instead of 'loff_t'
The kernel syscall uses 'loff_t', but the glibc wrapper uses 'off64_t'.
Let's document the wrapper prototype, as in other pages.
spu_create.2
Alejandro Colomar
SYNOPSIS: Fix prototype parameter type
The 'flags' parameter of spu_create() uses 'unsigned int'.
spu_run.2
Alejandro Colomar
SYNOPSIS: Fix prototype parameter types
The 2nd and 3rd parameters of spu_run() use 'uint32_t *'.
stat.2
Jonathan Wakely [Alejandro Colomar]
Remove <unistd.h> from SYNOPSIS
There seems to be no reason <unistd.h> is shown here, so remove it.
Michael Kerrisk
Move the obsolete _BSD_SOURCE FTM to the end of the FTM info
syscall.2
Peter H. Froehlich
Update superh syscall convention
syscalls.2
Michael Kerrisk
Add epoll_pwait2()
tkill.2
Alejandro Colomar
SYNOPSIS: Fix prototype parameter types
All but the last parameters of t[g]kill() use 'pid_t',
both in the kernel and glibc.
vmsplice.2
Alejandro Colomar
SYNOPSIS: Fix prototype parameter type
The 3rd parameter of vmsplice() uses 'size_t' in glibc.
bstring.3
Michael Kerrisk

Michael Kerrisk
Remove fileno(3) content that was migrated to new fileno(3) page
Michael Kerrisk
Add a RETURN VALUE section
Michael Kerrisk
POSIX.1-2008: these functions won't change 'errno' if 'stream' is valid
See https://www.austingroupbugs.net/view.php?id=401.
fread.3
Alessandro Bono
EXAMPLES: swap size and nmemb params
It works both ways, but this one feels more right. We are reading
four elements sizeof(*buffer) bytes each.
fseeko.3
Michael Kerrisk
Move info about obsolete FTM from SYNOPSIS to NOTES
This makes the SYNOPSIS more consistent with other pages.
ftime.3
Michael Kerrisk
glibc 2.33 has removed ftime()
ftw.3
Alejandro Colomar
SYNOPSIS: Remove duplicate header
gethostbyname.3
Michael Kerrisk
Move mention of <sys/socket.h> from SYNOPSIS to DESCRIPTION

get_phys_pages.3
Alejandro Colomar [Jakub Wilk]
glibc gets the info from sysinfo(2) since 2.23
grantpt.3
ptsname.3
unlockpt.3
Michael Kerrisk
Remove mention of _XOPEN_SOURCE_EXTENDED FTM
This rather ancient FTM is not mentioned in other pages for
reasons discussed in feature_test_macros(7). Remove this FTM
from the three pages where it does appear.

use of an empty prefix.
Bastien Roucariès [Alejandro Colomar, Bastien Roucaries, Vincent Lefevre]
Document valid values of pathnames for SHELL, PAGER and EDITOR/VISUAL
Michael Kerrisk [Bastien Roucariès]
Note the default if PAGER is not defined
Michael Kerrisk
Be a little more precise when discussing 'exec'
Say "execve(2)" instead of "exec(3)", and note that this step
starts a new program (not a new process!).
Michael Kerrisk [Bastien Roucariès]
Relocate and reword the mention of _GNU_SOURCE
man-pages.7
Michael Kerrisk
Document "acknowledgement" as the preferred spelling
Michael Kerrisk

Michael Kerrisk
Add a FORMATTING AND WORDING CONVENTIONS section
In man-pages-5.11, a large number of pages were edited to achieve
greater consistency in the SYNOPIS, RETURN VALUE and ATTRIBUTES
sections. To avoid future inconsistencies, try to capture some of
the preferred conventions in text in man-pages(7).
Michael Kerrisk
Note some rationale for the use of real minus signs
netdevice.7
