Retitled subsection "(Un)supported features" to "Sockets API"
This is consistent with the recent change in tcp(7).

+
+Changes to individual pages
+---------------------------
+
+gethostid.2
+ Michael Kerrisk
+ Move to Section 3
+ The interfaces documented in this page are purely glibc.
+
+syscalls.2
+ Michael Kerrisk
+ Kernel 2.6.28 adds accept4()
+
+clock_getres.3
+ Michael Kerrisk
+ SEE ALSO: Add pthread_getcpuclockid(3)
+
+fmemopen.3
+ Michael Kerrisk
+ Fix VERSIONS information
+
+gethostid.3
+ Michael Kerrisk
+ Before version 2.2, glibc stored the host ID in /var/adm/hostid
+ Also: rewrite some text describing the /etc/hostid file, so that
+ this location is referred to just once on the page.
+ Michael Kerrisk
+ RETURN VALUE: describe return value of sethostid()
+ Michael Kerrisk
+ Added BUGS section noting that ID can't be guaranteed to be unique
+ Michael Kerrisk
+ Added ERRORS section describing errors for sethostid()
+ Michael Kerrisk
+ Update section number to reflect relocation into Section 3
+
+printf.3
+ Michael Kerrisk
+ Source and destination buffers may not overlap for *s*printf()
+ http://sourceware.org/bugzilla/show_bug.cgi?id=7075
+
+ Some existing code relies on techniques like the following to
+ append text to a buffer:
+
+ $ cat s.c
+ #include <stdio.h>
+ char buf[80] = "not ";
+ main()
+ {
+ sprintf(buf, "%sfail", buf);
+ puts(buf);
+ return 0;
+ }
+
+ $ cc s.c
+ $ ./a.out
+ not fail
+
+ However, the standards say the results are undefined if source
+ and destination buffers overlap, and with suitable compiler
+ options, recent changes can cause unexpected results:
+
+ $ cc -v 2>&1 | grep gcc
+ gcc version 4.3.1 20080507 (prerelease) [gcc-4_3-branch revision 135036] (SUSE Linux)
+ $ cc -D_FORTIFY_SOURCE -O2 s.c
+ $ ./a.out
+ fail
+
+readdir.3
+ Michael Kerrisk
+ Rewrite text describing 'dirent' fields standardized in POSIX.1
+ Michael Kerrisk
+ Clarify text for return value/errno setting for end-of-stream case
+
+nscd.8
+ Petr Baudis
+ Correct NOTES section on reloading configuration files
+ It behaved this way at least since
+ "Sun Oct 18 15:02:11 1998 +0000",
+ some four months after including the nscd implementation
+ in glibc. But there does seem to be a short window between
+ glibc-2.1 and glibc-2.1.3 when nscd -i was not available,
+ I don't think it's worth muddling the point of the page
+ with that, though.

+Changes to individual pages
+---------------------------
+
+bind.2
+ Michael Kerrisk
+ SEE ALSO: Add getifaddrs(3)
+
+epoll_create.2
+ Michael Kerrisk
+ Document EMFILE error
+ This error is encountered when the limit imposed by
+ /proc/sys/fs/epoll/max_user_instances is encountered.
+ Michael Kerrisk
+ Clarify distinction between epoll instance and epoll file descriptor
+ Reword so that the notion of an epoll instance is made clear,
+ and made distinct from the notion of an epoll file descriptor.
+ Some other minor rewordings also.
+
+epoll_ctl.2
+ Michael Kerrisk
+ Reordered parts of the text
+ Michael Kerrisk
+ Introduce notion of epoll instance
+ Introduce notion of epoll instance as distinct from
+ epoll file descriptor. Plus other wording clean-ups.
+ Michael Kerrisk
+ Document ENOSPC error (new in Linux 2.6.28)
+ This error results when the limit imposed by
+ /proc/sys/fs/epoll/max_user_watches is encountered.
+
+epoll_wait.2
+ Michael Kerrisk
+ Introduce the notion of an epoll instance into text
+
+getdents.2
+ Michael Kerrisk
+ Before kernel < 2.6.4, 'd_type' was effectively always DT_UNKNOWN
+
+gethostid.2
+ Michael Kerrisk
+ Rename file (was misnamed gethostd.2 in previous release)
+
+getsockname.2
+ Michael Kerrisk
+ SEE ALSO: Add getifaddrs(3)
+
+signalfd.2
+ Michael Kerrisk
+ Fix description of fork() semantics
+ The page text described the semantics of the initial
+ implementation of signalfd(). These were changed early on,
+ but the man page wasn't updated.
+
+byteorder.3
+ Michael Kerrisk
+ SEE ALSO: add endian(3)
+
+longjmp.3
+ Michael Kerrisk
+ Clarify wording re saving/restoring signal mask
+ Michael Kerrisk
+ siglongjmp() restores signal mask iff 'savesigs' was non-zero
+ Note that siglongjmp() restores signal mask if, and only
+ if, 'savesigs' argument of sigsetjmp() was non-zero. (Previous
+ text omitted the "and only if".)
+
+memccpy.3
+ Michael Kerrisk
+ Fix CONFORMING TO: s/C99/POSIX.1-2001/
+ Michael Kerrisk
+ If the memory areas overlap, the results are undefined
+

+ Michael Kerrisk

+
+strsep.3
+ Michael Kerrisk
+ BUGS: explicitly list problems afflicting strsep()
+ Previously, the page said this function suffered the same
+ problems as strtok(), but in fact strsep() doesn't suffer
+ from all of the same problems as strtok(), so explicitly
+ list just the problems of strsep() in the strsep.3 page.
+
+proc.5
+ Michael Kerrisk
+ Add pointer to epoll(7) for description of epoll /proc files
+
+epoll.7
+ Michael Kerrisk

+ Michael Kerrisk
+ Global fix: s/(3)/(2)/ in section number xrefs for timer_*() API
+ The POSIX timers API is implemented (mostly) within the kernel,
+ so thse interfaces are system calls. Although there are as yet
+ no man pages, when they are added they should be in Section 2,
+ not 3. Therefore fix those pages that currently refer to these
+ interfaces as being in Section 3.
+
+
+Changes to individual pages
+---------------------------
+
+capget.2
+ Andi Kleen
+ Add some details and relocate a paragraph
+ While writing a little program using capset

+ determining whether we use this flag.
+
+nanosleep.2
+ Michael Kerrisk
+ Relocated misplaced BUGS heading
+
+select_tut.2
+ Michael Kerrisk
+ Clean up error checking in example program (no semantic changes)
