* The term "device_index" identifies currently plugged in joystick devices between 0 and SDL_NumJoysticks, with the exact joystick

|
|
*
|
|
* The term "instance_id" is the current instantiation of a joystick device in the system, if the joystick is removed and then re-inserted
|
|
* then it will get a new instance_id, instance_id's are monotonically increasing identifiers of a joystick plugged in.
|
|
*
|
|
* The term JoystickGUID is a stable 128-bit identifier for a joystick device that does not change over time, it identifies class of
|
|
* the device (a X360 wired controller for example). This identifier is platform dependent.
