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.

As part of this chapter, we mainly covered the Stack and Heap segments and the way they should be used. After that, we briefly discussed memory-constrained environments and we saw how techniques like caching and memory pools can increase the performance.

In this chapter:

  • We discussed the tools and techniques used for probing both Stack and Heap segments.
  • We introduced debuggers and we used gdb as our main debugger to troubleshoot memory-related issues.
  • We discussed memory profilers and we used valgrind to find memory issues such as leakages or dangling pointers happening at runtime.
  • We compared the lifetime of a Stack variable and a Heap block and we explained how we should judge the lifetime of such memory blocks.
  • We saw that memory management is automatic regarding Stack variables, but it is fully manual with Heap blocks.
  • We went through the common mistakes that happen when dealing with Stack variables.
  • We discussed the constrained environments...
