Now let us present an implementation of a producer-consumer system using condition variables. This implementation works.
dequeue()
lock(A)
while (queue empty) {wait(A, C) // atomically releases lock A and sleeps, waiting for// condition variable C.// When the thread wakes up, it re-acquires the lock.// C is the condition variable that means ''queue not empty''.}
remove_item()unlock(A)enqueue()lock(A)insert_item()signal(C)unlock(A)
In dequeue() above, if the thread wakes up and by chance the queue is empty, there is no problem: that's why we need the "while" loop.
