ft_list_foreach |

Assignment name  : ft_list_foreach
Expected files   : ft_list_foreach.c, ft_list.h
Allowed functions: 
--------------------------------------------------------------------------------

Write a function that takes a list and a function pointer, and applies this
function to each element of the list.

It must be declared as follows:

void    ft_list_foreach(t_list *begin_list, void (*f)(void *));

The function pointed to by f will be used as follows:

(*f)(list_ptr->data);

You must use the following structure, and turn it in as a file called
ft_list.h:

typedef struct    s_list
{
    struct s_list *next;
    void          *data;
}                 t_list;
---------------------------------------------------------------
#include <stdlib.h>
#include "ft_list.h"

void	ft_list_foreach(t_list *begin_list, void (*f)(void *))
{
	if (begin_list == 0)
		return;
	while (begin_list != 0)
	{
		f(begin_list->data);
		begin_list = begin_list->next;
	}
}

//--------------------------------------------------------
// #include <stdio.h>

// void	int_doubler(void *n)
// {
// 	int *num = (int *)n;
// 	*num = *num * 2;
// }

// int		main(void)
// {
// 	t_list *pt_a = malloc(sizeof(t_list));
// 	int	n_a = 0;
// 	pt_a->data = &n_a;
// 	pt_a->next = 0;

// 	t_list *pt_b = malloc(sizeof(t_list));
// 	int	n_b = 3;
// 	pt_b->data = &n_b;
// 	pt_b->next = 0;

// 	t_list *pt_c = malloc(sizeof(t_list));
// 	int	n_c = 4;
// 	pt_c->data = &n_c;
// 	pt_c->next = 0;

// 	pt_a->next = pt_b;
// 	pt_b->next = pt_c;

// 	t_list *cur = pt_a;
// 	while (cur != 0)
// 	{
// 		printf("%d, ", *(int *)(cur->data));
// 		cur = cur->next;
// 	}
// 	printf("\n");

// 	ft_list_foreach(pt_a, int_doubler);

// 	cur = pt_a;
// 	while (cur != 0)
// 	{
// 		printf("%d, ", *(int *)(cur->data));
// 		cur = cur->next;
// 	}
// 	printf("\n");
// }
