Re: XFree86 4.3/4.4: distinguish between two mouses?

I'm suprised that this is not a common request for
games (two input devices for two gamers).

First of all I've to correct myself. It looks like
I didn't understood (and still don't understand)
the XInput extension. On the other side looking at
Gimp it looks like there is a way to handle my problem
just with this XInput extension.

I don't need two cursors, just the posibility which user
(= which mouse) did a button press.

Very much thanks for this offer. But I think it should be much
easyer for me to learn to use the XInput extension
than to patch the X11-Server :-)

If someone has a patch for libSDL to add XInput would be nice.
Or may be someone has a *realy* simple sample code how to use
XInput.
    My fault was to think that the XDeviceButtonPressedEvent
is send like a normal XButtonPressedEvent (e.g. fetched by
XNextEvent (). But it's just a normal XButtonPressedEvent..
