Peter Hutterer 3aca819940 dmx: force -fno-strict-aliasing for xinput example 
Compiler warning:
xinput.c:272: warning: dereferencing pointer 'e' does break strict-aliasing
rules

The code itself is the usual XInput client-side code:
        XEvent event;
        XDeviceMotionEvent *e = (XDeviceMotionEvent *)&event;
        XNextEvent(display, &event);
        printf("%d\n", e->type);

Since XDeviceMotionEvent is not guaranteed the same size as XEvent, clients
must use pointer aliasing as above when using the XNextEvent API. Disable
strict aliasing for this example.

					X Server

The X server accepts requests from client applications to create windows,
which are (normally rectangular) "virtual screens" that the client program
can draw into.

Windows are then composed on the actual screen by the X server
(or by a separate composite manager) as directed by the window manager,
which usually communicates with the user via graphical controls such as buttons
and draggable titlebars and borders.

For a comprehensive overview of X Server and X Window System, consult the
following article:
http://en.wikipedia.org/wiki/X_server

All questions regarding this software should be directed at the
Xorg mailing list:
