The goal of this assignment is to become familiar with semaphores in POSIX-based operating systems. You may have noticed that your fish’s swim mill might have acted a bit erratic! Your assignment is to modify the swim mill that you created with Assignment #3 to include a semaphore to control access to critical resources. Make sure that you have signal handing to terminate all processes, if needed. In case of abnormal termination, make sure to remove shared memory and semaphores as well. Use semget(2), semctl(2), and semop(2) to implement the semaphore. Your semaphore should receive the names of functions passed as parameters. Since different functions are required to access the critical resource, passing the functions as parameters will prove a clean option. The original assignment was to make a fishmill with a coordinator. c, fish. c, and pellet. c. The pellets are created in a shared memory 2d array and fall down towards the fish. The fish can only move left or right in the bottom row. When the fish and a pellet are in the same location, the fish eats the pellet and then moves towards the next pellet.
