C programming is known for developing systems software (operating systems, databases, network protocol stack, and virtualization technologies) and applications by efficiently utilizing system computational resources. In this book you will be exploring C programming key skills such as handling functions, arrays, strings, unions, pointers, and memory. While learning these key skills, you will be exploring important runtime error handling techniques and best practices to implement reliable and efficient C programs. It is necessary to develop runtime errors and performance handling code in your C applications before deploying them in the runtime environment. Otherwise your programs/applications can crash the system and/or be damaged by other malicious or error-prone applications. In order to help you in thinking of a runtime environment and handling possible issues, this book introduces and discusses how to use important opensource Linux tools (gcc, gdb, gcov, valgrind) for compilation, linking, debugging, code coverage, and handling memory leaks. This book’s chapters are organized in the following logical manner for easy and quick ways of learning complex concepts. In Chapters 1, 2, and 3, we discuss basic computer system architecture and essential operating systems concepts for implementing reliable and efficient C code. Then, you will go through C programming essential skills such as handling arrays, strings, unions, pointers, and memory management using open-source Linux tools (gcc, gdb, gcov, valgrind). In Chapters 4 and 5, you will be dedicatedly practicing runtime error handling and best practices in terms of Pointers usages, dynamic memory allocation handling, and accessing arrays, structures, strings, and buffers. Later you will learn the importance of these concepts while implementing system and network programming. Later in Chapters 6 and 7, you will explore the power of C programming in terms of system programming and high-performance computing; specifically, you will learn process and thread management for multitasking or multiprocessing through essential system calls. Mainly, you will learn programmer responsibilities in terms of process management tasks such as creating multiple processes, management of process segments, waiting for processes, termination activities, interprocess communication, synchronization issues, and handling exceptional conditions. These are necessary skills for handling external inputs and runtime errors and offering reliable deployment opportunities for running C applications with multiple processes or threads. Next, in Chapters 8 and 9, you will explore the power of C socket programming and important system calls to implement TCP/UDP network applications. You will start with a quick introduction of the TCP/IP stack and applications. Specifically, you will learn flexible and error-free ways for handling socket buffers, packets, and fields accessed through C dynamic memory, strings, and pointers concepts. Moreover, we will also discuss essential programming ways (blocking and nonblocking), essential socket options for handling network server/client applications, runtime errors, and performance issues. Finally, in Chapter 10, you will learn Linux namespaces and their role in virtualization. Specifically, you will learn C programming ways and system calls for handling Linux namespaces and control groups. You will be experimenting with important Linux namespaces such as process, memory, and networking to learn how the popular lightweight virtualization solutions are working. This chapter will help you to explore the importance of virtualization in cloud environments.
