The table () system call for 2.1.xx kernels.

This library is also used in gnome-utils/gtop/proc so if we change
it to use libgtop it can be used both for procps and gtop.

+===========
+
+	* We have some new ``suffix rules'':
+
+	  '__l' is a function defined in the client part;
+	  '__s' is a function defined in the sysdeps part and
+	  '__p' is a function that needs special priviledges.
+	  '__r' is mapped either on '__p' or on '__s'.
+	  the function without suffix is mapped on '__l'.
+
+	* We now decide at runtime whether or not using the server
+	is required for a particular function. All user programs
+	now call the '__l' function defined in '-lgtop' (in the lib
+	subdir). These functions either use 'glibtop_call__l' to
+	call the server or call the '__r' function.
+
+	* A function in the sysdeps directory now has the '__s' suffix
+	if it do not need any priviledges (and thus can be called directly
+	from client code) and the '__p' suffix otherwise (when it has to
+	be called from the server).
+
+	* If you call one of these functions:
+
+	  -> use the '__p' suffix to be sure to get the SUID-safe one
+	     (used in the server).
+	  -> use the '__s' suffix to be sure to get a function that
+	     doesn't need any priviledges.
+	  -> use the '__r' suffix otherwise (it is mapped either on the
+	     '__p' or on the '__s' one).
+
+	Only use the '__p' and '__s' functions in a 'GLIBTOP_SUID_<feature>'
+	conditional, otherwise you'll get undefined symbols !
+
+	* The server is now started from 'glibtop_init__r', but only when
+	it's really needed; for instance on DEC OSF/1 you only need it
+	for the proc* features - if you program only fetches the CPU usage,
+	now server will be started.
+
+	* Sorry, at the moment everything is a little bit unstable, I'm doing
+	heavy changes. I've just some great ideas which still need some work:
+
+	  -> I want to have a SUID server that only implements those features
+	     that need to be SUID; everything else uses the sysdeps code directly.
+
+	  -> If a program only uses stuff that do not need the server, the
+	     server will not be started at all.

+	  -> I'm working on some kind of proxy server that can be used on a remote
+	     host; in feature one can then use the MDI stuff from ghex in gtop to
+	     have notebook pages displaying processes from different hosts.
+
+	* Well it is as much unstable that it only works under Linux at the moment.
+
+1998-06-01  Martin Baulig  <martin@home-of-linux.org>
+
+	* sysdeps/common/sysdeps.c: now using '__r' functions,
+	they are #defined either as the '__p' or the '__s' ones.
+
+	* sysdeps/linux/*.c: changed call of 'glibtop_init__r',
+	it now takes two additional arguments.
+
+	* examples/{first.c, second.c}: now using 'glibtop_init'
+	instead of 'glibtop_init__r'.
+
+	* include/glibtop/sysdeps.h: added 'dummy' member so
+	'GLIBTOP_SYSDEPS_<feature>' now start with 1.
+
+	* include/glibtop/*.h: we now #define 'glibtop_get_<feature>'
+	as 'glibtop_get_<feature>__l' and 'glibtop_get_<feature>__r'
+	either as the '__p' or the '__s' function.
+
+	* lib/*.c: removed #if's - we now decide at runtime
+	whether to use the server or to call the appropriate
+	function for the sysdeps directory.
+
+1998-05-28  Martin Baulig  <baulig@merkur.uni-trier.de>
+
+	* src/server/main.c: we now use the '__p' functions,
+	but only if the appropriate 'GLIBTOP_SUID_<feature>'
+	has a non-zero value.
+	
+	* configure.in (@machine_incs@): always use 
+	`-I$(top_srcdir)/sysdeps/@sysdeps_dir@'; it's no
+	longer conditional.
+
+	* examples/Makefile.am: removed the '_linux' examples.
+	
+	* sysdeps/linux/*.c: renamed all functions implementing
+	features to '__s'.
+	
+	* lib/*.c: renamed all functions implementing features
+	to '__l'; we only emit code for those functions if the
+ 	corresponding 'GLIBTOP_SUID_<feature>' has a positive value.
+	
+	* include/glibtop/*.h: added some new function suffixes:
+	'__l' is a function defined in the client part;
+	'__s' is a function defined in the sysdeps part and
+	'__p' is a function that needs special priviledges.
+	'__r' is mapped either on '__l' or on '__s'.
+	
+	* sysdeps/linux/glibtop_server.h: New file -
+	defines system dependent constants 'GLIBTOP_SUID_<feature>'
+	being either 'GLIBTOP_SYSDEPS_<feature>'+1 depending upon
+ 	whether or not this feature requires using the server.
+
+	* lib/sysdeps.c: removed that file; it is no longer
+	needed.

+This is a new system call `table ()' for the Linux table. It is faster
+than reading from /proc and can be used to fetch all information required
+for libgtop until whe have some other function (extended sysctl, ...) in
+standard kernels.
+
+I didn't want to change sysctl or some other function myself cause this may
+cause other applications relying upon those function to fail. This is
+something for the ``real'' kernel gurus ...
+
+To use this new system call for libgtop, do the following:
+
+* Copy this directory to /usr/src/linux/table
+* Make /usr/src/linux/include/linux/table.h symlink to /usr/src/linux/table/table.h
+* Apply the patch `kernel.patch' to the kernel, compile, install and reboot
+* Recompile libgtop (remove `config.cache' and run the `autogen.sh' again).
+
+If you want to change and/or add something - feel free to do so !
+
+Have fun,
+
+Martin

+This is a new system call `table ()' for the Linux table. It is faster
+than reading from /proc and can be used to fetch all information required
+for libgtop until whe have some other function (extended sysctl, ...) in
+standard kernels.
+
+I didn't want to change sysctl or some other function myself cause this may
+cause other applications relying upon those function to fail. This is
+something for the ``real'' kernel gurus ...
+
+To use this new system call for libgtop, do the following:
+
+* Copy this directory to /usr/src/linux/table
+* Make /usr/src/linux/include/linux/table.h symlink to /usr/src/linux/table/table.h
+* Apply the patch `kernel.patch' to the kernel, compile, install and reboot
+* Recompile libgtop (remove `config.cache' and run the `autogen.sh' again).
+
+If you want to change and/or add something - feel free to do so !
+
+Have fun,
+
+Martin

+This is a new system call `table ()' for the Linux table. It is faster
+than reading from /proc and can be used to fetch all information required
+for libgtop until whe have some other function (extended sysctl, ...) in
+standard kernels.
+
+I didn't want to change sysctl or some other function myself cause this may
+cause other applications relying upon those function to fail. This is
+something for the ``real'' kernel gurus ...
+
+To use this new system call for libgtop, do the following:
+
+* Copy this directory to /usr/src/linux/table
+* Make /usr/src/linux/include/linux/table.h symlink to /usr/src/linux/table/table.h
+* Apply the patch `kernel.patch' to the kernel, compile, install and reboot
+* Recompile libgtop (remove `config.cache' and run the `autogen.sh' again).
+
+If you want to change and/or add something - feel free to do so !
+
+Have fun,
+
+Martin

+mult_lvl_cmp:
+    slick general purpose multi-level compare function I invented.
+sort_depth:
+    the number of levels of functions *to use*.  This means many more levels
+    can be defined than mult_lvl_cmp tres out.  If this is 1 then mult_lvl_cmp
+    is just a trivial wrapper around (*sort_function[0]).
+sort_direction:
+    multiplicative factor for the output of cmp_whatever.
+    1 ==> default order, -1 ==> reverse order, 0 ==> forced equality
+    The 0 bit is the neat part.  Since a value of zero is the code for equality
+    multiplying the output of cmp_foo(a,b) forces a==b to be true.  This is a
+    convenient way to turn sorting off in middle levels of a multi-level sort.
+    If time is a problem, reforming the whole sort_function array to not include
+    these unsorted middle levels will be faster since then cmp_foo won't even
+    be called.  It might simplify some code depending upon how you organize it.
+sort_function[]:
+    array of function pointers that points to our family of comparison functions
+    (I have named them cmp_* but mult_lvl_cmp doesn't care what they're named).
+    This may be declared and initialized like so:
+       int (*sort_function[])(void* a, void* b)={&cmp_foo, &cmp_bar, &cmp_hiho};
+    You could also use my command line '-O' parser below.
+
+Note that we only descend levels until the order is determined.  If we descend
+all levels, that means that the items are equal at all levels, so we return 0.
+Otherwise we return whatever the level's cmp_foo function would have returned.
+This allows whatever default behavior you want for cmp_foo.  sort_direction[]
+reverses this default behavior, but mult_lvl_cmp doesn't decide that ascending
+or descending is the default.  That is the job of your cmp_foo's.

+Using this program on over 700 files in /dev to perform number->name resolution
+took well under 300 microsecs per device number pair on a Pentium 90.  It is
+somewhat tough to time because once the 3 pages have been mapped in, the time is
+almost zero.  For things like top, this method may even be faster in the long
+run.  Those interested can gprof it for me.  This system has the virtue of being
+nearly perfectly adaptable to individual systems, self updating when /dev
+changes and pretty darn fast when it hasn't.  It will be slow for users without
+perms to change the psdevtab file, though.  So this is what I decided was
+reasonable.  If the process does not have perms to create or update
+/etc/psdevtab and it is out of date, we try /tmp/psdevtab.  If /tmp/psdevtab is
+either out of date or unreadable (malicious user creates it and chmods it),
+$HOME/.psdevtab is used.  This secondarily allows for per-user naming of ttys,
+but is really so that at most one user sees only a single delay per /dev
+modification.
+
+To do the timings I did something like this with zsh:
+    a=(`ls -l *(%^@/) | awk '{print $5 $6}' | sed 's/,/ /'`);
+    time ./test $a

+old algorithmic device number <-> device name mappings.
