Learning More about Process Management

You became familiar with the concept of processes in the previous chapter. Now, it’s time to get into details. It is important to understand how process management is related to the system’s overall behavior. In this chapter, we will emphasize fundamental OS mechanisms that are used specifically for process control and resource access management. We will use this opportunity to show you how to use some C++ features too.

Once we’ve investigated the program and its corresponding process as system entities, we are going to discuss the states that one process goes through during its lifetime. You are going to learn about spawning new processes and threads. You are also going to see the underlying problems of such activities. Later we are going to check out some examples while slowly introducing the multithreaded code. By doing so, you will have the opportunity to learn the basics of some POSIX and C++ techniques that are related...
