malloc

malloc is a project that aims to recreate functions from the stdlib.h library.

Functions

// Mandatory functions
void * malloc (size_t len);
void free (void * ptr);
void *  realloc (void * ptr, size_t len);
void show_alloc_mem (void);

// Bonus functions

void show_alloc_mem_ex (void);
// void defragmentation (void);

// My functions

void free_heap (void);
[...]

Defines

// All those defines can be changed into the Makefile by changing 0 with 1.

#define DEBUG; 
// If set the program will print information about malloc and free calls.

#define LEAK_SAFETY;
// If set the program will automatically free every leaks at the end of the program.

#define CHECK_ALL;
// If set the program will add more information for each malloc, free or realloc calls.
// You will be able to detailed every leaks (file, line number, function)

#define LEAKS;
// If set the program will automatically print every leaks at the end of the program

Usage

// You must include "inc/libmalloc.h" in your C program.
