FT_DESTRUCTOR

A lightweight C library that automates memory cleanup. It ensures all allocated memory is properly freed in case of allocation fail or at program exit. In short it's simplifying memory management and minimizing memory leaks.

Installation

Clone repository

git clone https://github.com/Emsa001/ft_destructor

Compile to ft_alloc.a

cd ft_destructor
make

Add to your application

cc main.c ft_alloc.a -o my_program

Functions

• Init / Get the list with all allocations

t_allocs *ft_allocs(t_allocs *lst);

• Allocations

void *ft_malloc(size_t size);
void *ft_calloc(size_t count, size_t size)

• Destructors

void ft_free(void *ptr);
void ft_destructor(void);

Demo

#include "ft_alloc.h"

int	main(void)
{
	// init list for allocations
	ft_alloc_init();

	// allocations with ft_malloc
	char *str = ft_malloc(455 * sizeof(char));
	char *str2 = ft_malloc(455 * sizeof(char));
	char *str3 = ft_malloc(455 * sizeof(char));

	// manual free
	ft_free(str);  
	ft_free(str2);
	ft_free(str3);

	int i = 0;
	while (i < 10)
	{
		// allocation without ft_free
		char *str4 = ft_malloc(455 * sizeof(char));
		(void)str4;
		i++;
	}

	// original malloc - won't be freed with destructor
	char *str5 = malloc(455 * sizeof(char)); 
	(void)str5;

	// will free everything that was allocated with ft_malloc or ft_calloc
	ft_destructor(); 
	return (0);
}
