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.

Reclamation and finalization at the end of the program

Our second implementation will not only free the underlying storage for the objects allocated through our deferred reclamation system but will also finalize them by calling their destructors. To do so, we will need to remember the type of each object that goes through our system. There are, of course, many ways to achieve this, and we will see one of them.

By ensuring the finalization of reclaimed objects, we can get rid of the trivially destructible requirement of our previous implementation. We still will not guarantee the order in which objects are finalized, so it’s important that reclaimed objects do not refer to each other during finalization if we are to have sound programs, but that’s a constraint many other popular programming languages also share. This implementation will, however, keep the singleton approach and finalize and then deallocate objects and their underlying storage at the end of program execution...
