The following are changes in previous 2.xx man page releases. ==================== Changes in man-pages-2.00 ==================== Released: 2004-12-16 (why wait for the kernel?) Contributors ------------ The following people contributed notes, ideas, or patches that have been incorporated in changes in this release: Alberto Bertogli Anand Kumria Andrey Kiselev Andries Brouwer Chris Green Branden Robinson Emmanuel Colbus Enrico Zini Eric Estievenart Fabian Kreutz Florian Weimer Jan Kuznik Joey (Martin) Schulze Johannes Berg John V. Belmonte Karel Kulhavy Luis Javier Merino Morán Martin Pool Richard Kreckel Vasya Pupkin Apologies if I missed anyone! Global changes -------------- Many math pages had their synopses compressed, as per suggestion from Fabian Kreutz. Many minor content and formatting bug fixes were made to the math pages, following suggestions from Fabian Kreutz (who recently translated many of the 1.70 math pages into German) and Andries Brouwer. For consistency, all instances "super-user" were changed to the more common "superuser". After a note from Vasya Pupkin, I added to the SYNOPSIS of several Section 2 pages using the _syscallN() macros. In addition: -- erroneous semicolons at the end of _syscallN() were removed on various pages. -- types such as "uint" in syscalN() declarations were changed to "unsigned int", etc. -- various other minor breakages in the synopses were fixed. The affected pages are: getdents.2 gettid.2 llseek.2 mmap2.2 modify_ldt.2 pivot_root.2 quotactl.2 readdir.2 sysctl.2 syslog.2 tkill.2 Typographical or grammatical errors have been corrected in several other places.

Global changes -------------- Matthew Dempsky, mtk triggered by http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=283179 The wording describing how errno is set was fixed up in the following pages: accept.2 close.2 send.2 setsid.2 socket.2 closedir.3 initgroups.3 mkstemp.3 opendir.3 readdir.3 telldir.3 Typographical or grammatical errors have been corrected in several other places. Individual pages ---------------- sendfile.2 mtk Adjusted descriptions of argument file types to be closer to 2.6 reality. Wording and formatting changes ctan.3 ctanh.3 Tony Crawford As per http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=270817 Formulae on the pages should be T = S / C not T = C / S. errno.3 Martin Schulze, mtk Removed errno declaration from prototype, added notes on historical need for this declaration. http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=174175 aio_return.3 as per http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=224953 Changed erroneous "aio_return(2)" to "aio_return(3)" posix_openpt.3 mtk New by mtk ptsname.3 mtk Added description of ptsname_r().

SUSv3 says 0..60. I think the manual page probably says 0..61, because that's what SUSv2 said. (Some other implementations' man pages also say 0..61 -- e.g., Solaris 8 & 9, Tru64 5.1B; FreeBSD 5.1 says 0..60.) The glibc manual currently says 0..60. Given that SUSv3 says 0..60, I've changed the manual page to also say this: -The second as a decimal number (range 00 to 61). +The second as a decimal number (range 00 to 60). +(The range is up to 60 to allow for occasional leap seconds.) sysconf.3 Johannes Berg / http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=226974 -.BR POSIX2_FORT_RUN " - " _SC_2_FORT_DEV +.BR POSIX2_FORT_DEV " - " _SC_2_FORT_DEV system.3 Pedro Zorzenon as per http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=242638 Noted use of _XOPEN_SOURCE to get macros as for wait(2). mtk Changed name of argument from 'string' to 'command' (like POSIX). Noted that glibc does nowadays explicitly check for the existence of the shell if 'command' is NULL, rather than the older behaviour of assuming the shell exists and always returning 1 if 'command' is NULL. Other wording and formatting clean-ups. undocumented.3 Remove some functions names that *are* documented. ==================== Changes in man-pages-2.02 ==================== Released: 2005-04-14 Contributors ------------ The following people contributed notes, ideas, or patches that have been incorporated in changes in this release: Andries Brouwer Branden Robinson Colin Watson David Lloyd Gordon Jin Heikki Orsila Jamie Lokier Johan Walles Kai Makisara Marko Kohtala Martin Pool Martin (Joey) Schulze Matthias Lang Michael Haardt Michael Mühlebach Mike Frysinger Sasa Stevanovic Serguei Leontiev Apologies if I missed anyone!

(Pipes are implemented as STREAMS on the former, and sockets on the latter.) posix_fadvise.2 mtk Noted kernel version where posix_fadvise() appeared and noted bug in handling of 'len' in kernels < 2.6.6. rename.2 Michael Haardt Clarified EXDEV error description: it isn't possible to rename a file across mount points, even if the mount points refer to the same file system. semop.2 mtk Noted kernel version numbers for semtimedop(). setitimer.2 Matthias Lang, mtk Noted MAX_SEC_IN_JIFFIES ceiling. Added note about treatment of out-of-range tv_usec values. sigqueue.2 Johan Walles, Martin (Joey) Schulze Added sigqueue.2 to SEE ALSO times.2 mtk Added notes on non-standard behaviour: Linux allows 'buf' to be NULL, but POSIX.1 doesn't specify this and it's non-portable. uselib.2 Andries Brouwer Improved DESCRIPTION; clarified distinction between EACCES and ENOEXEC. bcopy.3 Heikki Orsila bcopy() handles overlapping case, but memcpy does not, so for consistency memmove() should be also mentioned. getmntent_r.3 Martin (Joey) Schulze New link to man3/getmntent.3. memcpy.3 Small wording change after suggestion from Sasa Stevanovic. strcasestr.3 mtk Created as link to strstr.3. strftime.3 mtk Noted that SUSv2 allowed a range of 00 to 61 for %S specifier. strstr.3 mtk Added description of strcasestr(). random.4 aeb Improved description of read from /dev/urandom. st.4 Kai Makisara Substantial updates. man.7 Martin Schulze Branden Robinson Colin Watson Mention the .URL macro more verbosely. ==================== Changes in man-pages-2.03 ==================== Released: 2005-06-02 Contributors ------------ The following people contributed notes, ideas, or patches that have been incorporated in changes in this release: Andries Brouwer Joey (Martin) Schulze Johannes Nicolai Justin Pryzby Klaus Ethgen Pavel Heimlich Ross Boylan Vincent Fourmond Apologies if I missed anyone!

Noted changes in permissions required for SHM_LOCK/SHM_UNLOCK. wait.2 mtk Noted that the __W* flags can't be used with waitid(). getconf.3 mtk Added_CS_GNU_LIBC_VERSION and_CS_GNU_LIBPTHREAD_VERSION. hosts.5 Ross Boylan / Martin Schulze various changes as per http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=304242 proc.5 mtk Minor changes to discussion of /proc/PID/stat signal fields.
