C++ System Programming Cookbook

By: Onorato Vaticone

Overview of this book

C++ is the preferred language for system programming due to its efficient low-level computation, data abstraction, and object-oriented features. System programming is about designing and writing computer programs that interact closely with the underlying operating system and allow computer hardware to interface with the programmer and the user. The C++ System Programming Cookbook will serve as a reference for developers who want to have ready-to-use solutions for the essential aspects of system programming using the latest C++ standards wherever possible. This C++ book starts out by giving you an overview of system programming and refreshing your C++ knowledge. Moving ahead, you will learn how to deal with threads and processes, before going on to discover recipes for how to manage memory. The concluding chapters will then help you understand how processes communicate and how to interact with the console (console I/O). Finally, you will learn how to deal with time interfaces, signals, and CPU scheduling. By the end of the book, you will become adept at developing robust systems applications using C++.

Scheduling

System programming is about interacting with the underlying OS. The scheduler is one of the core components of every OS and impacts the way processes are allocated on CPUs. Ultimately, this is what the end user is concerned about: processes running smoothly and with correct priority over other processes. This chapter will teach you the practical skills you need in order to interact with the scheduler by changing the process' policy, its nice value, the real-time priority, processor affinity, and how real-time processes can yield the processor.

This chapter will cover the following recipes: 

  • Learning to set and get a scheduler policy 
  • Learning to get the timeslice value
  • Learning how to set a nice value
  • Learning how to yield the processor
  • Learning about processor...
