A call to xname returns the minimum KeyCode value
supported by the specified display to
.A min_keycodes_return
and the maximum KeyCode value supported by the
specified display to
.A max_keycodes_return .
>>STRATEGY
Call xname.
Use min keycode with XGrabKey.
Verify that it gives no error.
Use min keycode minus one with XGrabKey.
Verify that it gives an error.
Use max keycode with XGrabKey.
Verify that it gives no error.
Use max keycode plus one with XGrabKey.
Verify that it gives an error.
