Enable/disable joystick event polling.
Defined in SDL_joystick.h, but apps should only #include "SDL.h"
!
int SDL_JoystickEventState(int state);
state | can be one of SDL_QUERY , SDL_IGNORE , or SDL_ENABLE |
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.
If joystick events are disabled, you must call SDL_JoystickUpdate() yourself and manually check the state of the joystick when you want joystick information.
It is recommended that you leave joystick event handling enabled.
WARNING: Calling this function may delete all events currently in SDL's event queue.
This function is available since SDL 2.0.0.
