Use this function to enable/disable joystick event polling.
int SDL_JoystickEventState(int state)
can be one of SDL_QUERY, SDL_IGNORE, or SDL_ENABLE
Note: You may use -1, 0, or 1 in place of SDL_QUERY, SDL_IGNORE, or SDL_ENABLE respectively.
Returns 1 if enabled, 0 if disabled, or a negative error code on failure; call SDL_GetError() for more information.
If state is SDL_QUERY then the current state is returned, otherwise the new processing state is returned.
printf("%i\n", SDL_JoystickEventState(SDL_QUERY)); /* prints 1 */ printf("%i\n", SDL_JoystickEventState(SDL_IGNORE)); /* prints 0 */ printf("%i\n", SDL_JoystickEventState(SDL_QUERY)); /* prints 0 */
If joystick events are disabled, you must call SDL_JoystickUpdate() yourself and manually check the state of the joystick when you want joystick information.
Note: It is recommended that you leave joystick event handling enabled.
WARNING: Calling this function may delete all events currently in SDL's event queue.
