Memory Allocation Project

This project implements a memory allocation system in C, that i made as part of my Operating systems 2 course.

Overview

The project consists of two files:

• heap.h: Header file containing function prototypes and struct definitions.
• heap.c: Source file containing the implementation of memory allocation functions.

Functions

heap_setup()

Initializes the memory manager.

heap_clean()

Frees all allocated memory and resets the memory manager.

heap_malloc(size_t size)

Allocates a block of memory of the given size.

heap_calloc(size_t number, size_t size)

Allocates memory for an array of elements, initialized to zero.

heap_realloc(void *memblock, size_t count)

Changes the size of the memory block pointed to by memblock.

heap_free(void *memblock)

Frees the memory block pointed to by memblock.

heap_validate()

Validates the integrity of the heap.

get_pointer_type(const void *const pointer)

Determines the type of the pointer.

heap_get_largest_used_block_size()

Returns the size of the largest used memory block.

Usage

To use the memory allocation functions, include heap.h in your source files and link with heap.c.

Example

#include "heap.h"
#include <stdio.h>

int main() {
    heap_setup();
    
    // Example usage
    void *ptr = heap_malloc(10);
    heap_free(ptr);
    
    heap_clean();
    
    return 0;
}
