Memory manager for C++ project?

Question

C++ / C#

For self-learning purposes, I decided to write a simple memory manager for my projects (hypothetically). All the literature I found describes the process of writing it under Linux, but I'm interested in the Windows platform. (maybe I just searched badly, poke your nose, it will also be useful).
A rather banal question is also of interest - how to actually test this? Well, tobish, how to understand whether the same garbage collector is working correctly, or defragmentation (if it is needed) ...
Much appreciated.

Answer 1

First, decide whether you need a memory manager (alloc/free) or a garbage collector?
And secondly, regardless of the answer to the first question, where do you see the fundamental inapplicability of information about writing a memory manager or garbage collector for one OS to another OS? And in general, all the articles and books about garbage collectors that I read were written either in an OS-independent style, as a maximum, only a practical study of the characteristics was under one particular OS.

Perhaps this post will help you - zamotivator.dreamwidth.org/497156.html. At one time, quite well-known programmers in Runet, people threw decent links on allocators and garbage collections there.

Post death, now they use mostly smart pointers std:: shared_ptr
