Continuing from where we left of last time, I would like to discuss how we can build growing allocators using a virtual memory system. This post describes how to build a stack-like allocator that can automatically grow up to a given maximum size.

Before we can delve into the inner workings of growing allocators, I would like to explain the concept of virtual memory and discuss what it is, why it is needed, and what we can use it for.

One thing we haven’t discussed yet are the memory arenas which are responsible for actually allocating memory, while providing additional things like bounds checking, memory tracking, etc.
