C++ Memory Management

Overview of this book

Memory management in C++ isn't one-size-fits-all; real-time systems, games, and embedded applications each present unique memory constraints. This book delivers targeted solutions for each domain. Written by ISO C++ Standards Committee member, Patrice Roy, this guide covers fundamental concepts of object lifetime and memory organization to help you write simpler and safer programs. You’ll learn how to control memory allocation mechanisms, create custom containers and allocators, and adapt allocation operators to suit your specific requirements, making your programs smaller, faster, safer, and more predictable. From core principles to modern facilities that simplify your work, you’ll master memory management mechanics, build tailored memory solutions for your application needs, and measure their impact on your program’s behavior. By the end of this book, you’ll be able to write secure programs that handle memory optimally for your application domain. You will also have a strong grasp of both high-level abstractions for safer programs and low-level abstractions that allow detailed customization.

Why allocators?

Allocators tend to scare people, including some experts, but you will not be scared as you are already in possession of significant memory management knowledge and skills (and you are probably curious to know more about the topic given the fact that you are reading this book). Knowing this, the first question we need to address, before even expressing what an allocator is, is “Why do allocators exist?”. Why would we concern ourselves with an additional layer of complexity in our memory management code?

Well, this is C++, and C++ is all about giving users control, so that’s where our explanation begins. To make an analogy, think about iterators: why they are useful, and how they make your life as a programmer better. They decouple iterating over elements of a sequence from how the elements are organized in that sequence, such that you can write code that computes something such as the sum of the values in std::list<int> or std::vector&lt...
