Quickly, read the projects given to you and grade them, based on a 20 point scale. All we are looking for here is a program that has:

• A wrapper for semaphores, as simple as a number of functions or as complicated as a class (10 points).
• Of the 10 points for the wrappers, 5 should pertain to good error checking of the system calls. Terminating is fine for the error handling part, i.e., if a system call fails, it probably is best to not keep looping and retrying.
• Some reasonable approach to creating a unique key and then incrementing on each use of the key (3 points). ftok is fine, but they must use it at least once to get a unique key and then increment or decrement that key on each use. Starting with their UID is also fine.
• A set of processes 'nicely' using semaphores to control each other (5 Points).
• A Key point in the creation of the semaphore wrapper is to be able to control each semaphore. Previously, implementations have gotten into trouble with destructors killing off semaphores still in use.
• Please comment on this project. I wanted for the parent to create the child, yet the child to control the parent with the semaphore.
