Building a Memory Allocator from Scratch in C

이 글은 C 언어로 메모리 할당기(malloc/free)를 직접 구현하는 방법을 상세히 설명합니다. 힙 메모리 관리, 단편화 문제, 메모리 블록 분할과 병합(coalescing) 기법 등 메모리 할당기의 핵심 개념과 구현 세부사항을 다룹니다. 운영체제에서 메모리를 요청하는 sbrk() 호출부터 자유 리스트 관리, 첫 적합(first-fit) 전략 적용까지 실전 코드를 통해 메모리 할당 과정을 깊이 있게 이해할 수 있습니다. 성능과 신뢰성이 중요한 시스템 프로그래밍 및 임베디드 개발자에게 유용한 내용입니다.

👩‍💻 So, you decided to write a 20-minute #thesis on the Go runtime's memory allocator? Bravo! 🏆 Too bad it's as exciting as watching paint dry, except the paint is trying to manage memory allocations in a world where only #interns #care. 🚀💤

The Memory Allocator | Internals for Interns

In the previous article we explored how the Go runtime bootstraps itself — how a Go binary goes from the operating system handing it control to your func main() running. During that bootstrap, one of the first things the runtime sets up is the memory allocator. And that’s what we’re going to explore today. Think of the memory allocator as a warehouse manager. Your program constantly needs boxes of different sizes — sometimes tiny, sometimes huge — and it needs them fast. The allocator’s job is to hand out those boxes as quickly as possible, keep the warehouse organized so nothing goes to waste, and work with the garbage collector to reclaim boxes that nobody is using anymore.

🐢📦 Wow, someone wrote a memory allocator in C! 🧠🔧 Because, you know, the world has been desperately waiting for the millionth version of something that already exists. 😂 With GitHub's help, it's easier than ever to reinvent the wheel, but make it square! 🙄
