Expand description

Get the number of general axis controls on a joystick.

Often, the directional pad on a game controller will either look like 4 separate buttons or a POV hat, and not axes, but all of this is up to the device and platform.

\param joystick an SDL_Joystick structure containing joystick information \returns the number of axis controls/number of axes on success or a negative error code on failure; call SDL_GetError() for more information.

\since This function is available since SDL 2.0.0.
