22 !!DESCRIPTION
23
24
25 __SDL_!JoystickGetAxis__ returns the current state of the
26 given __axis__ on the given __joystick__.
27
28
29 On most modern joysticks the X axis is usually represented
30 by __axis__ 0 and the Y axis by __axis__ 1. The value
31 returned by __SDL_!JoystickGetAxis__ is a signed integer
32 (-32768 to 32768) representing the current position of the
33 __axis__, it maybe necessary to impose certain tolerances
34 on these values to account for jitter. It is worth noting
35 that some joysticks use axes 2 and 3 for extra
36 buttons.
37 !!RETURN VALUE

40 Returns a 16-bit signed integer representing the current
41 position of the __axis__.
