Classic Reader/Writer C program

complete description at [login to view URL]~cop4600sp04/prj/prj04/[login to view URL] This programming assignment is intended to familiarize you with a classic concurrency management problem known as *Readers and Writers*. It is also intended to familiarize you with multi-threading and semaphores in Unix. The *Readers and Writers* problem is described in Lecture 11 (Concurrency, semaphores, bounded buffer, readers & writers), <s>Lecture 16</s>Lecture 94 (About project 4) ,and Tanenbaum Section 2.4.2 (pages 128 and 129). Your solution should perform in all five of the following modes: 1. No concurrency management 2. Exclusive access to the shared resource for one reader or one writer only 3. Exclusive access to shared resource by a writer, and Concurrent access by any number of readers, as long as no writer is writing, plus readers and writers contend FIFO 4. Exclusive access to shared resource by a writer, and Concurrent access by any number of readers, as long as no writer is writing, plus readers have preference over waiting writers 5. Exclusive access to shared resource by a writer, and Concurrent access by any number of readers, as long as no writer is writing, plus writers have preference over waiting readers Additionally, your solution must allow any number of readers between zero and 19, as well as any number of writers between zero and 19. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law. Buyer will receive exclusive and complete copyrights to all work purchased. (No GPL, GNU, 3rd party components, etc. unless all copyright ramifications are explained AND AGREED TO by the buyer on the site per the coder's Seller Legal Agreement). ## Platform unix
