C++ Memory Management

By: Patrice Roy

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.

Writing Generic Containers with Allocator Support

We have come a long way since the beginning of this book. Recent chapters examined how one can write memory-efficient containers, describing how to do so when memory management is done explicitly (in Chapter 12) and when it is done implicitly, through smart pointers (in Chapter 13). Choosing a memory management approach is not an either/or proposition; each one is useful in its own way and solves real-life use cases depending on one’s application domain.

However, none of the approaches we have covered so far match what standard library containers do. Indeed, standard library containers (as well as many other standard library types that can dynamically allocate memory) are allocator-aware and delegate low-level memory management tasks to specialized objects that can be supplied by client code. There is merit to this idea as it allows one to pick a container based on the way it organizes objects in memory and couple said container...
