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.

Trivial relocation

As you know, dear reader, C++ is known in the programming community as one of those languages that we use when we need to get the most out of our computer or whatever hardware platform interests us. Some of the language’s credos can be paraphrased as “you shall not pay for what you do not use” and “there shall be no room for a lower-level language (except for the occasional bit of assembly code)”, after all. The latter explains the importance of the std::start_lifetime_... functions of the previous section.

That’s probably why, when it becomes evident that we could do even better than we are already doing in terms of execution speed, that becomes a subject of interest to the C++ programmer community in general, and more specifically to members of the C++ standards committee. We all take these core credos of the language to heart.

One case where we could do better is when we encounter types for which moving a source...
