C :: Reading A File Line By Line And Storing It Backwards Into A List

So I'm reading a file line by line and storing it backwards into a list. So if the file has has this format...
1
2
3
4

The code should store each line in a list as such...
4, 3, 2 ,1

Instead the code will store the last variable in all nodes. So the final list will look like this...
4, 4, 4, 4

Here is my code...

struct node *head = NULL;
int i;
while(read(in, &i, sizeof(int)) != 0) {
struct node *temp = malloc(sizeof(*temp));
temp->line = &i;
temp->next = head;
head = temp;
}
