Function sdl2_sys::SDL_LockJoysticks

pub unsafe extern "C" fn SDL_LockJoysticks()

Locking for multi-threaded access to the joystick API

If you are using the joystick API or handling events from multiple threads you should use these locking functions to protect access to the joysticks.

In particular, you are guaranteed that the joystick list won’t change, so the API functions that take a joystick index will be valid, and joystick and game controller events will not be delivered.

\since This function is available since SDL 2.0.7.
