CSCI3150 - IPC-Synchronization Problem

In this lab, you will see some synchronization problems between processes and learn how to solve them.

You need to do:

• Understand POSIX semaphore APIs (Section 3) and shared memory APIs (Section 4) before try programs in this lab.

• There are few programs in this lab, compile them, run them, understand them.

• Finish exercise.

After that, you should know:

• What race condition and critical region is.
• What semaphore and shared memory is.
• How to use POSIX named semaphores to solve synchronization problem between processes.
