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()
|
||||
|
||||

||||
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.

Retitled subsection "(Un)supported features" to "Sockets API"
