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.

The singleton design pattern

There are many design patterns out there. Design patterns are a topic of their own, representing well-known ways of solving problems that one can represent in the abstract, give a name to, explain to others, and then reify within the constraints and idioms of one’s chosen programming language.

The singleton design pattern describes ways in which we can write a class that ensures it is instantiated only once in a program.

Singleton is not a well-liked pattern: it makes testing difficult, introduces dependencies on global state, represents a single point of failure in a program as well as a potential program-wide bottleneck, complicates multithreading (if the singleton is mutable, then its state requires synchronization), and so on, but it has its uses, is used in practice, and we use it on occasion in this book.

There are many ways to write a class that is instantiated only once in a program with the C++ language. All of them share some key...
