Overview of this book

There’s a lot more to C than knowing the language syntax. The industry looks for developers with a rigorous, scientific understanding of the principles and practices. Extreme C will teach you to use C’s advanced low-level power to write effective, efficient systems. This intensive, practical guide will help you become an expert C programmer. Building on your existing C knowledge, you will master preprocessor directives, macros, conditional compilation, pointers, and much more. You will gain new insight into algorithm design, functions, and structures. You will discover how C helps you squeeze maximum performance out of critical, resource-constrained applications. C still plays a critical role in 21st-century programming, remaining the core language for precision engineering, aviations, space research, and more. This book shows how C works with Unix, how to implement OO principles in C, and fully covers multi-processing. In Extreme C, Amini encourages you to think, question, apply, and experiment for yourself. The book is essential for anybody who wants to take their C to the next level.

Stack and Heap

In the previous chapter, we ran an investigation of the memory layout of a running process. System programming without knowing enough about the memory structure and its various segments is like doing surgery without knowing the anatomy of the human body. The previous chapter just gave us the basic information regarding the different segments in the process memory layout, but this chapter wants us to just focus on the most frequently used segments: Stack and Heap.

As a programmer, you are mostly busy working with Stack and Heap segments. Other segments such as Data or BSS are less in use, or you have less control over them. That's basically because of the fact that the Data and BSS segments are generated by the compiler, and usually, they take up a small percentage of the whole memory of a process during its lifetime. This doesn't mean that they are not important, and, in fact, there are issues that directly relate to these segments. But as you are spending...
