1.	HandlePut(object o) performs what?(a) Fixing values(b) Locking(c) Changing values(d) UnlockingThe question was posed to me at a job interview.I'd like to ask this question from Multithreading topic in section Going Parallel, Handling Actuator and Sensor of IOT
Answer» The correct choice is (d) Unlocking Easiest explanation: void HandlePut(OBJECT o) method puts 0 into buffer. The new VALUE in the buffer replaces the old one. The method performs the necessary LOCKING to enable SAFE use of the buffer from multi THREADS.
