Memory Allocator Simulation in C

Overview

This repository contains a simple implementation of a memory allocator in C, providing a basic version of malloc() and free() functions. This project was developed as part of a university assignment, inspired by the logic outlined in an online article (link).

Features

  • Memory Allocation: The MyMalloc() function allocates a block of memory of the specified size.
  • Memory Deallocation: The MyFree() function frees a previously allocated block of memory.
  • Memory Block Information: The printMemoryBlocks() function prints information about the current state of memory blocks, including their status (allocated or free), size, and locations.

Usage

Clone repo

    git clone https://github.com/haathim/mymalloc.git
    cd mymalloc

Build & Run

    make
    ./main

Notes

  • The initialize() function initializes the memory pool if it hasn't been done already.
  • The memory pool is represented by a character array (mem_pool), with each character representing one byte.
  • The memory block structure (struct head) contains information about the block's status (free or allocated) and size.
  • The logic behind splitting and merging memory blocks is implemented to optimize memory usage.

Feel free to explore the code and experiment with different allocations and deallocations.
