It changes the return values of all sysdeps functions which were
previosly returning void to int.
This is the first step to implement better error handling in LibGTop.

* include/glibtop/*.h (glibtop_get_*, glibtop_init*): Changed
the return value of all `glibtop_get_<feature>_* ()' and all
`glibtop_init_<feature>_* ()' functions from void to int.
* features.def: Reflect changes of the return values.
* sysdeps/*/*.c: Reflect changes of the return values.
1999-03-20 Martin Baulig <martin@home-of-linux.org>
Removed all traces of my old table () Linux kernel hack.
* kernel: Removed.
* sysdeps/kernel: Removed.
* libgtop-sysdeps.m4: Don't check for table (); it does not
exist any longer.
1999-02-22 Martin Baulig <martin@home-of-linux.org>
Set the copyright of LibGTop to the GNU General Public License.
* copyright.txt: Set the year to 1998-99 and pretty-format it a
little bit. Same in all C source and header files.

* COPYING.LIB: Include a copy of the GNU Library General
Public License here.
* copyright.txt: Set the year to 1998-99 and pretty-format it a
little bit. Same in all C source and header files.

* include/glibtop/proc_signal.h: Use a 2-element-array of
type `u_int64_t' for all signal masks instead of just
scalar numbers. This avoids problems on systems with more
than 64 signals.
If there is any operating system out there with even more than
128 signals, we can simply increase the number of array elements
here.
[NOTE for people porting libgtop:
Please use all 64 bits of the `u_int64_t' and not just 32 - the
signal number (as it is used in calls to kill () ...) should be
a bit-index into this field; if a process ignores for instance
signal 64, it has the 0-bit of sigcatch[1] set, if it ignores 63,
this is the 63-bit of sigcatch[0] and so on ...
The mapping between signal numbers and their names is done via the
glibtop_sys_siglist [] field which should be declared in
sysdeps/@sysdeps_dir@/siglist.c - see linux for an example.
]
* features.def: It's now safe to put things like `loadavg[3]'
here - the awk skripts should correctly threat this as an array.
1998-08-07 Martin Baulig <martin@home-of-linux.org>
* glibtop.h (_glibtop): New fields `error_method', `sysdeps' and
`required'. I added an improved error handling: the client can tell
the libraries which fields are absolutely required for each features
and if it fails to set one of them, this will create an error which
is handled depending upon the `error_method'.
* include/glibtop/open.h: Define some constants for `error_method'.
* lib/sysdeps.c (glibtop_get_sysdeps_r): No longer actually call any
sysdeps function, it now simply copies `server->sysdeps'.
(_glibtop_init_hook_s): Added. List of functions to be called during
`glibtop_init_s' set to `glibtop_init_<no-suid-feature>_s'.
* include/glibtop/sysdeps.h (<glibtop/union.h>): Removed.
(glibtop_init_func_t): New typedef.
(_glibtop_init_hook_s): Added.
* sysdeps/linux/*.c (glibtop_init_<feature>_s): New functions.
(glibtop_get_proc_*): Zero is now a valid pid.
* sysdeps/kernel/*.c (glibtop_init_<feature>_s): New functions.
(glibtop_get_proc_*): Zero is now a valid pid.
1998-08-06 Martin Baulig <martin@home-of-linux.org>
1998-07-24 Martin Baulig <martin@home-of-linux.org>
* sysdeps/{kernel, linux}/*.c: Replaced `glibtop_init_r' with
`glibtop_init_s'.
* sysdeps/sun4/open.c (glibtop_init_p): Removed `program_name'
parameter.
* sysdeps/osf1/glibtop_suid.h: New file.
* sysdeps/osf1/glibtop_server.h: Now correctly using
`(1 << GLIBTOP_SYSDEPS_*)' instead of `GLIBTOP_SYSDEPS_*'.
* sysdeps/osf1/open_suid.c (glibtop_init_p): New function.
* sysdeps/osf1/proc*.c: Done some more work here.
1998-07-23 Martin Baulig <martin@home-of-linux.org>
* include/glibtop/procsignal.h (glibtop_proc_signal):
Changed type for `signal', `blocked', `sigignore' and
`sigcatch' to `unsigned long long'.
1998-07-21 Martin Baulig <martin@home-of-linux.org>
* doc/ChangeLog: New file.
* sysdeps/kernel/*.c: Using `glibtop_error_io_r' instead
of `glibtop_error_r'.
* sysdeps/kernel/proclist.c: Now using the table () function, too.
This means that currently the table () function can fetch all
information for libgtop and you can even unmount /proc !
1998-06-13 Martin Baulig <martin@home-of-linux.org>
The code in this directory fetches all information
directly from the kernel. It uses the new table ()
system call from the `kernel' directory.
