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 (without finalization) at the end of the program

Our first implementation will provide reclamation but not finalization at the end of program execution. For this reason, it will not accept managing objects of some type T if T is not trivially destructible since objects of that type have a destructor that might have to be executed to avoid leaks or other problems along the way.

With this example, as with the others in this chapter, we will start with our test code, and then go on to see how the reclamation mechanics are implemented. Our test code will go as follows:

  • We will declare two types, NamedThing and Identifier. The former will not be trivially destructible as its destructor will contain user code that prints out debugging information, but the latter will be, as it will only contain trivially destructible non-static data members and offer no user-provided destructor.
  • We will provide two g() functions. The first one will be commented out as it tries...
