+ *
+ * File: xinput.c
+ *
+ * Sample program to access input devices other than the X pointer and
+ * keyboard using the Input Device extension to X.
+ * This program creates a window and selects input from it.
+ * To terminate this program, press button 1 on any device being accessed
+ * through the extension when the X pointer is in the test window.
+ *
+ * To compile this program, use
+ * "cc xinput.c -I/usr/include/X11R5 -L/usr/lib/X11R5
+ * -lXi -lXext -lX11 -o xinput
