+/*
+
+ This file will be included by memory.cpp !
+
+ HP-UX is really ugly to retrieve information from !
+ Implemented on 24.04.1999 by Helge Deller (deller@gmx.de)
+ Tested on an HP9000/715/64 under HPUX-10.20.
+ Updated for QT 2.0 on 27.04.1999 (deller)
+
+ Sorry, but I don't know, who implemented the first (little) version of
+ update(), but it showed wrong sizes !
+
+ Many thanks goes also to Mike Romberg, who implemented such functions in
+ the program "xosview". Here's his copyright:
