Extreme C

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.

Summary

In this chapter, we completed our discussion regarding multi-processing environments. As part of this chapter, we discussed the following:

  • What a named semaphore is and how it can be created and used by multiple processes.
  • What a named mutex is and how it should be used using a shared memory region.
  • We gave an example which was about termination orchestration in which a number of processes were waiting for a sign to get terminated and the signal was received and handled by one of the processes and propagated to others. We implemented this example using shared mutexes.
  • What a named condition variable is and how it can become shared and named using a shared memory region.
  • We demonstrated another example of counting processes. As part of this example, we used inheritance to reduce the amount of code duplication for mutex and condition variable objects having an associated shared memory region.
  • We briefly explored the differences and challenges found...
