SDL_JoystickGetAxis(3)			SDL API Reference		   SDL_JoystickGetAxis(3)

NAME
       SDL_JoystickGetAxis- Get the current state of an axis

SYNOPSIS
       #include "SDL.h"

       Sint16 SDL_JoystickGetAxis(SDL_Joystick *joystick, int axis);

DESCRIPTION
       SDL_JoystickGetAxis returns the current state of the given axis on the given joystick.

       On  most  modern  joysticks  the X axis is usually represented by axis 0 and the Y axis by
       axis 1. The value returned by SDL_JoystickGetAxis is a signed integer  (-32768  to  32768)
       representing the current position of the axis, it maybe necessary to impose certain toler-
       ances on these values to account for jitter. It is worth noting that  some  joysticks  use
       axes 2 and 3 for extra buttons.

RETURN VALUE
       Returns a 16-bit signed integer representing the current position of the axis.

EXAMPLES
       Sint16 x_move, y_move;
       SDL_Joystick *joy1;
       .
       .
       x_move=SDL_JoystickGetAxis(joy1, 0);
       y_move=SDL_JoystickGetAxis(joy1, 1);
