Hallo Steve,

thanks for your reply! As I am not yet even near 60 years old, I don't
get the reference. But I am old enough to sense, that I probably won't
get much deeper into C programming anymore, than wrapping shell commands
into the 'system()' function to make them setuid'able. Thus, I will
leave the 'xinput' sources where they are and rather use some spare
time to see if I can can get any useful information out of 'gdb'. If I
succeed, I promise to report to the list - although I don't own a
device with touchpad (which most likely would be the second thing to
permanently disable immediately - right after the system sounds, if my
OS had those preconfigured).

Libre Grüße and best regards,
Florian
