Locking for multi-threaded access to the sensor API


void SDL_LockSensors(void);


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

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


This function is available since SDL 2.0.14.
