noleaks ✅

No memory leaks in c. Are you tempted? 😎

Introduction

Personally, I hate memory leaks! It's too easy a mistake, too difficult to detect and far too fatal.

That's why I've coded a small library that will detect your memory leaks. So you don't have to worry about it.

TOO GOOD ISN'T IT?!

Docs

Simple and effective you know malloc? you know free? prefix with nl and do as usual 😎.

Add a small debugging function to find out where the leaks are, and you've got the solution.

⚠️ with large memory values in multithreaded mode, some bugs have yet to be resolved.

Prototype :

void *nlmalloc(size_t size);
void nlfree(void *ptr);
void check_memory_leaks(void);

Exemple

#include "./include/noleaks.h"

int	main(void)
{
	int	*array;

	// Allocation de mémoire pour un tableau de 10 entiers
	array = (int *)nlmalloc(10 * sizeof(int));
	// Vérification si l'allocation a réussi
	if (array == NULL)
	{
		ft_printf("Erreur d'allocation de mémoire\n");
		return (1);
	}
	// Remplissage du tableau avec des valeurs
	for (int i = 0; i < 10; i++)
	{
		array[i] = i;
	}
	// Affichage des valeurs du tableau
	for (int i = 0; i < 10; i++)
	{
		ft_printf("%d ", array[i]);
	}
	ft_printf("\n");
	// Libération de la mémoire allouée
	// nlfree(array);
	// (Optionnel) Vérification des fuites de mémoire à la fin du programme
	check_memory_leaks();
	return (0);
}

result:

if you uncomment "nlfree()".
