Hi,
After a good night sleep I found the (rather obvious) answer myself.
The initialisation code which depends on the myInteger token goes into
parse_myInteger(). The handler will get called before any gets/sets
are processed and also gets called on SIGHUP, just what I need. All
very obvious, I blame it on lack of sleep :-)
Thanks,
Holger
