###### (This is the legacy documentation for stable SDL2, the current stable version; [SDL3](https://wiki.libsdl.org/SDL3/) is the current development version.) # SDL_JoystickEventState Enable/disable joystick event polling. ## Header File Defined in [SDL_joystick.h](https://github.com/libsdl-org/SDL/blob/SDL2/include/SDL_joystick.h) ## Syntax ```c int SDL_JoystickEventState(int state); ``` ## Function Parameters | | | | | --- | --------- | -------------------------------------------------------------------------------------------------- | | int | **state** | can be one of [`SDL_QUERY`](SDL_QUERY), [`SDL_IGNORE`](SDL_IGNORE), or [`SDL_ENABLE`](SDL_ENABLE). | ## Return Value (int) Returns If `state` is [`SDL_QUERY`](SDL_QUERY) then the current state is returned, otherwise `state` is returned (even if it was not one of the allowed values). ## Remarks If joystick events are disabled, you must call [SDL_JoystickUpdate](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. While `param` is meant to be one of [`SDL_QUERY`](SDL_QUERY), [`SDL_IGNORE`](SDL_IGNORE), or [`SDL_ENABLE`](SDL_ENABLE), this function accepts any value, with any non-zero value that isn't [`SDL_QUERY`](SDL_QUERY) being treated as [`SDL_ENABLE`](SDL_ENABLE). If SDL was built with events disabled (extremely uncommon!), this will do nothing and always return [`SDL_IGNORE`](SDL_IGNORE). ## Version This function is available since SDL 2.0.0. ## See Also - [SDL_GameControllerEventState](SDL_GameControllerEventState) ---- [CategoryAPI](CategoryAPI), [CategoryAPIFunction](CategoryAPIFunction), [CategoryJoystick](CategoryJoystick)
