Locking for atomic access to the joystick API.
Defined in <SDL3/SDL_joystick.h>
void SDL_LockJoysticks(void);
The SDL joystick functions are thread-safe, however you can lock the joysticks while processing to guarantee that the joystick list won't change and joystick and gamepad events will not be delivered.
This function is available since SDL 3.1.3.
