SDL_LockJoysticks - Man Page

#include <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.

It is safe to call this function from any thread.

This function is available since SDL 3.2.0.
