New and rewritten pages
-----------------------
acct.5
mtk
A complete rewrite of this page, now with much more detail.
hostname.7
mtk
A description og hostnames.
Taken from FreeBSD 6.2, and lightly edited for man-pages style.
symlink.7
mtk
Taken from FreeBSD 6.2, but heavily edited for Linux details,
improved readability, and man-pages style.
Newly documented interfaces in existing pages
---------------------------------------------
getrlimit.2
mtk / Peter Zijlstra
Add description of RLIMIT_RTTIME limit, new in 2.6.25.
mkstemp.3
mtk
Add description of mkostemp(), new in glibc 2.7.
core.5
mtk, after a note by Petr Gajdos; review by Neil Horman
Document core_pattern pipe syntax, which appeared in
kernel 2.6.19.
Add an example program demonstrating use of core_pattern
pipe syntax.
mtk
Document /proc/PID/coredump_filter, new in kernel 2.6.23.
Documentation was based on the text in
Documentation/filesystems/proc.txt, plus testing, and
reading the kernel source.
proc.5
mtk
Document /proc/PID/oom_score, which was new in kernel 2.6.11.
This file displays the "badness" score of the process, which
provides the basis for OOM-killer decisions.
mtk
Document /proc/PID/oom_adj, which was new in kernel 2.6.11.
This file influences the oom_score of a process.
mtk
Document /proc/PID/limits, which was new in 2.6.24.
This file displays a process's resource limits.
mtk
Document /proc/PID/fdinfo/*, which was new in 2.6.22.
These files display info about each descriptor opened by the
process: the current file offset, and the file access mode +
file status flags as set in open() or fcntl(F_SETFL).
mtk
Document /proc/PID/mountinfo, which was new in 2.6.26.
This file displays information about mount points.
Closely based on text from Documentation/filesystems/proc.txt.
mtk
Document /proc/PID/mountstats, which was new in 2.6.17.
This file displays statistics about mount points.
New links
---------
mkostemp.3
mtk
Link to mkstemp.3.
getcwd.2
mtk
Link to getcwd.3, which describes several interfaces, among
them getcwd(), which is in fact a system call.

Changes to individual pages
---------------------------
acct.2
mtk
Add a few more words to DESCRIPTION.
NOTES: Add pointer to acct(5).
alarm.2
Alain Portal
s/process/calling process/ so as to that the alarm signal is
delivered to the calling process.
brk.2
Yao Zhao / mtk
Clarify discussion of return value of sbrk().
mtk
DESCRIPTION: Add some sentences giving an overview of these
interfaces.
Add note recommending use of malloc(3).
Change name of brk() argument to the simpler 'addr'.
Add "(void *)" cast to "-1" for error return of sbrk().
Removed some incorrect text about "brk(0)".
Note that SUSv2 specified the return value of sbrk().
Added a detail on the glibc brk() wrapper.
Remove discussions of standards old (C89 and POSIX.1-1990);
CONFORMING TO already discusses the situation with respect
to more recent standards.
chmod.2
mtk
Clarify description of chmod() and fchmod().
Add further detail on S_ISUID, S_ISGID, and S_ISVTX permissions.
Reformat list of permissions bits.
chown.2
mtk
Describe rules governing ownership of new files (bsdgroups
versus sysvgroups, and the effect of the parent directory's
set-group-ID permission bit).
chroot.2
Alain Portal
Clarify description a little.
s/changes the root directory/
changes the root directory of the calling process/
execve.2
mtk
Fix text that warns against use of NULL argv and envp.
Using a NULL envp does in fact seem to be portable (works
on Solaris and FreeBSD), but the Linux semantics for a NULL
argv certainly aren't consistent with other implementations.
See http://bugzilla.kernel.org/show_bug.cgi?id=8408.
mknod.2
mtk
Note that EEXIST applies, even if the pathname is a
(possibly dangling) symbolic link.
open.2
mtk, after a note from Christoph Hellwig
NOTES: Note that access mode flags are not single bits,
and document the Linuxism "access mode 3".
See also http://thread.gmane.org/gmane.linux.kernel/653123.
sched_setscheduler.2
mtk
Add pointer to discussion of RLIMIT_RTTIME in getrlimit.2.
mtk, after a note by Andrew Clayton
Rewrote and restructured various parts of the page for greater
clarity.
mtk
Add more detail to the rules that are applied when an
unprivileged process with a non-zero RLIMIT_RTPRIO limit
changes policy and priority.
syscalls.2
mtk
Added system call history back to version 1.2.
Fix typo on kernel version for pivot_root().
sync_file_range.3
Pavel Machek
SYNC_FILE_RANGE_WRITE can block on writes greater than request
queue size. For some background, see
http://thread.gmane.org/gmane.linux.kernel/687713/focus=688340
dprintf.3
mtk
Note that these functions are included in the next POSIX revision.
Remove editorial discussion about what the functions should have
been named.
getaddrinfo.3
mtk
Improve description or 'hints' and 'res' arguments.
Add details on numeric strings that can be specified for 'node'.
Other fairly major restructrings and rewrites to improve
logical structure and clarity of the page.
SEE ALSO: Add hostname(7).
gethostbyname.3
mtk
DESCRIPTION: Add reference to inet_addr(3) for dotted notation.
SEE ALSO: add inet(3).
mtk
Added BUGS section noting that gethostbyname() does not
recognize hexadecimal components in dotted address strings;
See http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=482973
getmntent.3
mtk, after Stuart Cunningham pointed out the typo
Remove statement that LSB deprecates the functions
"endmntent(), setmntent() [sic] and setmntent()".
This doesn't seem to be true (I can't find mention of it
being deprecated in any of the LSB specs). Rather, LSB simply
doesn't specify these functions. (LSB 1.3 had a spec of
setmntent(), but not getmntent() or endmntent(), and noted
that having a spec of setmntent() was of little use without
also having a spec of getmntent().)
See also https://lists.linux-foundation.org/pipermail/\
lsb-discuss/2006-October/003078.html
getnameinfo.3
Tolga Dalman
Remove mention of sa_len field from example code.
That field is a BSDism not present on Linux.
mtk
Various minor changes.
inet.3
mtk / Stephane Chazelas
inet_aton() is *not* in POSIX.1.
Rewrite discussion of why inet_addr() is disfavored.
SEE ALSO: Add getaddrinfo(3).
as per http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=482979.
mtk, after a note by Stephane Chazelas
Describe the various address forms supported by inet_aton().
mtk
Rewrite description of inet_network().
Clarify discussion of inet_lnaof(), inet_netof(), and inet_makeaddr().
Add discussion of Classful Addressing, noting that it is obsolete.
Added an EXAMPLE program.
mtk
Relocate discussion of i386 byte order to NOTES.
Note that inet_aton() returns an address in network byte order.
SEE ALSO: Add byteorder(3) and getnameinfo(3).
inet_ntop.3
mtk
Remove unneeded header files from SYNOPSIS.
SEE ALSO: Add inet(3) and getnameinfo(3).
Make NAME line more precise.
Move errors to an ERRORS section.
Add EXAMPLE section pointing to inet_pton(3).
inet_pton.3
mtk / Stephane Chazelas
Remove statement that inet_pton() extends inet_ntoa();
that's not really true, since inet_pton() doesn't support
all of the string forms that are supported by inet_ntoa().
SEE ALSO: Add getaddrinfo(3).
as per http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=482987.
mtk
Describe IPv6 address formats.
Describe dotted decimal format in more detail.
Add an example program.
mtk
Remove unneeded header files from SYNOPSIS.
Make NAME line more precise.
Make description of return value more precise.
SEE ALSO: Add inet(3).
mkfifo.3
mtk
Note that EEXIST applies, even if the pathname is a
(possibly dangling) symbolic link.
mkstemp.3
mtk
Fix discussion of O_EXCL flag.
These functions may also fail for any of the errors described
in open(2).
Various other rewordings.
remainder.3
mtk
Recommend against drem(), in favor of remainder().
strcat.3
Andreas Herrmann
s/strcat/strncat/ (a typo that changed the semantics in
DESCRIPTION).
strerror.3
mtk, after a note from Daniele Giacomini
Modify SYNOPSIS to show protoypes of both versions of strerror_r(),
and make other small clarifications of the description regarding
the two versions.
man-pages.7
mtk
Enhanced description of VERSIONS section.
mq_overview.7
mtk
Note that Linux does not currently support ACLs for POSIX
message queues.
sem_overview.7
mtk
Note that Linux supports ACLs on POSIX named semaphores
since 2.6.19.
unix.7
mtk, after a note by Samuel Thibault
Provide a clear description of the three types of address that
can appear in the sockaddr_un structure: pathname, unnamed,
and abstract.
