Inside My Custom malloc: Bins, tcache, mmap, and Thread Safety

Most developers use malloc without thinking much about what happens underneath. This project is an attempt to explore that layer by building a memory allocator from scratch in C. The allocator implements malloc , free , calloc , and realloc without relying on libc’s heap functions. It focuses on: Thread safety Per-thread caching (tcache) Efficient free block management using bins mmap-based memory growth Handling large allocations separately This article breaks down the design, implementation de
