====
o Documentation under AIX is rather cryptic and incomplete. I managed to read
the process table using undocumented calls : getproc, getuser, getargs.
I've read C code from Vic Abell <abe@purdue.edu> in lsof-4.36, Jussi Maki
<Jussi.Maki@csc.fi> and Marcel J.E. Mol <marcel@mesa.nl> in monitor-2.1.2
as well as a usenet news posted by Michael Wojcik <mike@raederle.mfltd.co.uk>
(Article: 63164 of comp.unix.aix, Date: 04/04/95)
[lsof is a really nice tool and provides C examples to read low-level
structures under nearly any UNIX system on earth. ]
o my port was only tested under the following conditions :
AIX 4.1.5
perl 5.005_02
o I am not a C programming terminator, so consider this as really ALPHA
software.
o I wanted this tool to be usable by a non root user. This is why I don't read
/dev/kmem unlike Vic and Jussi.
Bugs
====
o When mapping tty device numbers to names, I get a 'permission denied' message
due to the /dev/.SRC-unix directory whose perms are as follows :
drwxrwx--- 2 root system 512 Aug 12 11:26 .SRC-unix/
This dir contains only a few unix domain socket files used by IBM's System
Resource Controller, so it is of no interest for getting ttynames.
Maybe we should bind STDERR to /dev/null
o I sometimes get :
"Can't access `pctmem' field in class Proc::ProcessTable::Process"
It comes from the AUTOLOAD function defined in Process.pm. How come we are
able to access fields like "pctcpu" but not "pctmem" ? I am puzzled.
We may chenge the 'croak' statement to a 'warn' but it'd be better if we
knew where this error comes from.
o Hidden ones ? I bet there is some ...
