Linux Heap Memory Manager

A custom-designed Heap Memory Manager built from scratch in C for Linux environments.
This project re-implements and enhances core memory allocation functionalities such as calloc() and free() — with internal & external fragmentation prevention, block coalescing, and visualization of the heap state.---

Features

• Custom heap allocator built entirely from scratch (no system malloc).
• Implements XMALLOC() (like calloc) and XFREE() (like free).
• Prevents internal and external fragmentation using block splitting & merging.
• Includes utilities to inspect and visualize memory blocks in use.
• Modular structure with separate Memory Manager and Glue Thread modules.
• Fully tested using testapp.c.

Compilation

gcc -Iinclude -Iglthread -g -c src/testapp.c -o build/testapp.o

gcc -Iinclude -Iglthread -g -c src/mm.c -o build/mm.o

gcc -Iinclude -Iglthread -g -c glthread/glthread.c -o build/glthread.o

gcc -Iinclude -Iglthread -g build/testapp.o build/mm.o build/glthread.o -o build/test.exe

Then run: ./build/test.exe
