41 * An SDL_GUID is a 128-bit identifier for an input device that
42 * identifies that device across runs of SDL programs on the same
43 * platform. If the device is detached and then re-attached to a
44 * different port, or if the base system is rebooted, the device
45 * should still report the same GUID.
46 *
47 * GUIDs are as precise as possible but are not guaranteed to
48 * distinguish physically distinct but equivalent devices. For
49 * example, two game controllers from the same vendor with the same
50 * product ID and revision may have the same GUID.
51 *
52 * GUIDs may be platform-dependent (i.e., the same device may report
