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.

Standard resource management automation tools

The standard library offers a significant number of classes that manage memory efficiently. One needs only consider the standard containers to see shining examples of the sort. In this section, we will take a quick look at a few examples of types useful for resource management. Far from providing an exhaustive list, we’ll try to show different ways to benefit from the RAII idiom.

As mentioned before, when expressing a type that provides automated resource management, the key aspects of that type’s behavior are expressed through its six special member functions. For that reason, with each of the following types, we will take a brief look at what the semantics of these functions are.

unique_ptr<T> and shared_ptr<T>

This short section aims to provide a brief overview of the two main standard smart pointers types in the C++ standard library: std::unique_ptr<T> and std::shared_ptr<T>. It is meant...
