Syntax

int SDL_JoystickEventState(int state)

Function Parameters

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.

Return Value

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.

Code Examples

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 */

Remarks

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.
