Spin off of my malloc project @ 42 Network, to help finding leaks

Leak Finder

Development repository for the leak finder utility developed @ 42 Heilbronn

This is a project built on top of ft_malloc to help find leaks on other projects.

Usage

1. clone this repo.

# clone this repo.
$ git clone git@github.com:iwillenshofer/leak_finder.git
$ make

2. Add the malloc.h header as the first header in your project.

# add as the first header in your project
#include "malloc.h"

#set this to the folder you cloned the repo, relative to your project
$ export LEAK_FINDER=./leak_finder
$ gcc -L./${LEAK_FINDER} -lft_malloc -I./${LEAK_FINDER}/includes  main.c
$ ./a.out

Example of main() file

#include "malloc.h"
#include <string.h>
#include <stdio.h>

int	main(void)
{
	char *s;
	char *string = "hello world";
	size_t size = strlen(string);

	s = malloc(size + 1);
	s[size] = '\0';
	memcpy(s, string, size);
	printf("Malloc'd string: %s\n", s);
	show_alloc_mem_ex();
	print_leaks();
	free(s);
	return (0);
}
