Thread: Reading a file into a Linked List

I am trying to read a file into a linked list. However, I seem to be having trouble since the printf statement doesn't print anything useful. Here is sample code:

void main(void)
{

struct box *current=NULL;

FILE *fp;
fp=fopen("file", "r");

while(fscanf(fp, "%s%f%f", current->name, &current->x, &current->y) != EOF)

current = (struct box *)malloc(sizeof(struct box); /*not sure if malloc is useful here*/
printf("%s%f%f", current->name, current->x, current->y)
reutrn;
}

I am simply trying to scan in the file, but the program will only print the last line in the file, and not all lines. What is wrong here?

Allocation of memory for current should be done before you use the variable current. Function malloc does not need casting.

Besides checking if the file did open correctly, also check the value malloc returns.

Before the program finishes, the allocated memory must be freed.

BTW, I don't see anything which has to do with linked lists. I only see that you try to read something in the same struct again and again until end of file is reached.
