event device and X11 keycodes

[Matthias Grimm <matthiasgrimm@users.sourceforge.net>]

Hi,
Is there a relation between the keycodes from the event devices
/dev/input/event% and the X11 key events? Which?

How can I get the event deveice keycodes in an X11 application
without opening the /dev/input/event% devices?

  Best Regards
