This is true for Windows, Linux, and macOS. Almost every network stack is programmed in C. The use of the C programming language is ubiquitous. They connect over an Ethernet connection, Wi-Fi, cellular, a phone line, fiber optics, and other media, but they likely have one thing in common they likely use C. These devices use a wide variety of hardware. Over 20 billion devices are estimated to be connected to the internet now. The new Internet of Things ( IoT) trend has people rushing to connect even more unlikely devices every day. However, billions of additional devices are now connected as well-mobile phones, tablets, gaming systems, vehicles, refrigerators, television sets, industrial machinery, surveillance systems, doorbells, and even light bulbs. Certainly, millions of desktops, laptops, routers, and servers are connected to the internet and have been for decades. Today, the internet needs no introduction. You’ll work with robust, reliable, and secure code that is portable across operating systems, including Winsock sockets for Windows and POSIX sockets for Linux and macOS.

The code in this book is compatible with the older C99 version as well as the latest C18 and C++17 standards. Finally, you’ll study network monitoring and implement security best practices.īy the end of this book, you’ll have experience of working with client-server applications and be able to implement new network programs in C. As you advance, you’ll gain insights into asynchronous socket programming and streams, and explore debugging and error handling. The book will also cover HTTP and HTTPS for communicating between your browser and website, and delve into hostname resolution with DNS, which is crucial to the functioning of the modern web.

You’ll explore client-server and peer-to-peer models for information sharing and connectivity with remote computers. With its support for third-party libraries and structured documentation, C is an ideal language to write network programs.Ĭomplete with step-by-step explanations of essential concepts and practical examples, this C network programming book begins with the fundamentals of Internet Protocol, TCP, and UDP.

Network programming enables processes to communicate with each other over a computer network, but it is a complex task that requires programming with multiple libraries and protocols.
