Homework : Operating System Concepts Using kernel objects (such as semaphore, critical section, mutex lock, event) to realize reader-writer problem. As for mutex locks, semaphores see example.cpp. Readers-Writers Problem Writer Process wait(wrt); writing is performed signal(wrt); Reader process wait (mutex); readcount++; if (readcount signal (mutex); 1) wait(wrt); == reading is performed wait (mutex); readcount--; if (readcount == 0) signal (wrt); signal (mutex):
