I do not want to impose any conclusions. I showed some ways to reach my goal. The solution of the XS library was quite a lot of work in this particular case, but usually much easier. Both other solution were really simple. The programs are much shorter and simpler than in the original atsar, including the extra of a graphical display.

I support the arguments of Linus Torvalds in favour of communication in text from /proc to the programs in stead of the traditional communication in binary structures: alignment and byte-ordering differences between systems makes life much harder than needed. Textual communication requires string-parsing which is simple in most languages but C, and has little overhead as long as the language supports associative arrays (hashes).
