*
|
|
* nearly all joystick functions can be regarded as obsolete,
|
|
* as Linux (2.1.x) now supports extended joysticks
|
|
* with a completely new joystick driver interface
|
|
* new driver's docu says:
|
|
* "For backward compatibility the old interface is still included,
|
|
* but will be dropped in the future."
|
|
* Thus we should implement the new interface and at most keep the old
|
|
* routines for backward compatibility.
