A Comprehensive Look at Memory Management

In this chapter, we will step the reader through how to properly and safely perform C++-style memory management, while also adhering to the C++ Core Guidelines whenever possible, leveraging additions to the C++ standard template library in C++11, C++14, and C++17 to increase the safety, reliability, and stability of the reader's system program. We will start by first introducing the new() and delete() functions, and how they may be used to allocate type-safe memory, including aligned memory. Next, this chapter will discuss the safety issues with using new() and delete() directly and how these safety concern may be handled using smart pointers, including their impact on C++ Core Guideline compliance. How to perform memory mapping and permissions will also be discussed, with the chapter concluding with a brief discussion on fragmentation...
