Double linked lists and a structure to hold them plus a name.

Assignment: Create a double linked list and then create a structure to hold each double linked list with a name. I figured that with each double linked list that the user can create I can just add it to the end of a single linked list.

The link structure below is used to hold the name of the list, the list created by the user, and a pointer to the next link. To make a list the user just enters: "c listName" from stdin. I can create mutliple lists and it seems just fine until I use void printList(..) to see if the single linked list is indeed intact. If I would enter: c List1 then c List2 and then c List3 and print them out to see if I have List1 List2 List3, I get List3 List3 List3.

I've tried for hours (pathetically) to see what can be wrong and I just cannot get it. A hint to the next step would greatly help me out!

Code:

//Structure for the collection of double-linked lists.
struct link {
	char *name;
	struct link *next;
	list currentList;
};


void insertNewList(struct link **head, char *data) {
	struct link* temp;
	struct link* temp1;
	list x;

	x = create();
	temp = (struct link*) malloc(sizeof(struct link));

	temp -> name = data;
	temp -> currentList = x;
	temp -> next = *head;

	*head = temp;
	printf("The name of the new list is: %s\n", (*head) -> name);
}

void insertStringToList(struct link **head, char *data, char *listName) {
	struct link* temp;
	temp = *head;

	if (strcmp(temp -> name, listName) == 0) {
		printf("we found a match.\n");
	} else {
		printf("the listName was not found.\n");
	}
}

void printList(struct link **head) {
	struct link* temp;
	temp = *head;

	printf("%s  ", temp -> name);
	while (temp != NULL) {
		printf("%s  ", temp -> name);
		temp = temp -> next;
	}
	printf("\n");
}

Code:

>void insertNewList(struct link **head, char *data) {
>	struct link* temp;
>	struct link* temp1;
>	list x;

>	x = create();
>	temp = (struct link*) malloc(sizeof(struct link));


>	temp -> name = data;
//Should be:
	temp -> name = malloc(sizeof(strlen(data)+1));
	strcpy(temp -> name,  data);
