building 3 double linked list

I need to build 3 double linked lists of numbers. It is a part of a larger program I write, which will compare elemnts of those lists. After searching thoroughly archive could not find it. This is what I wrote, but I know it's a false.
please help!

Code:

---

#include <stdio.h>
#include <stdlib.h>
#include <string.h>

typedef struct NodeStruct Node;
typedef Node *NodePointer;
struct NodeStruct{
        int value;
        NodePointer next;
        NodePointer previous;
};

NodePointer newNode (NodePointer prevNode, int value)
{
        NodePointer newNode;
        newNode=(NodePointer)malloc (sizeof(Node));
        newNode->next=NULL;
        newNode->previous=prevNode;
        prevNode->next= newNode;
        newNode->value= value;
        return newNode;
}
       

NodePointer CreateList (NodePointer head)
{
        NodePointer current;
        current = head;
        current->previous=NULL;
        current->next=NULL;
        return current;
}



void main ()
{
        Node head1, head2, head3;
        NodePointer current1, current2, current3;
        int count=0;

        /*creating emtpy list no. 1*/
        current1=CreateList(&head1);
        /*populating list 1*/
        puts ("enter an integer:");
        scanf("%d",current1->value);
        while(current1->value!=0)
        {
                puts ("enter an integer:");
                scanf("%d",&current1->value);
                current1->next=newNode(current1, current1->value);
                current1 = current1->next;
        }

       
        /*creating emtpy list no. 2*/
        current2=CreateList(&head2);
        /*populating list 2*/
        puts ("enter an integer:");
        scanf("%d",current2->value);
        while(current2->value!=0)
        {
                puts ("enter an integer:");
                scanf("%d",&current2->value);
                current2->next=newNode(current2, current2->value);
                current2 = current2->next;
        }

       
        /*creating emtpy list no. 3*/
        current3=CreateList(&head3);
        /*populating list 3*/
        puts ("enter an integer:");
        scanf("%d",current3->value);
        while(current3->value!=0)
        {
                puts ("enter an integer:");
                scanf("%d",&current3->value);
                current3->next=newNode(current3, current3->value);
                current3 = current3->next;
        }

}

Well, first off, this is wrong:

Code:

---

        scanf("%d",current3->value);

---

You need to pass the address of current3->value instead of the value of current3->value to scanf().

OK, code get copmiled after fixing this, but program is crashes after first integer input.

Code:

---

        current1=CreateList(&head1);
        /*populating list 1*/
        puts ("enter an integer:");
        scanf("%d",current1->value);

---

CreateList() isn't allocating memory for the node, so where is the input actually being stored?

Sometimes I just get the urge to say things like: "Yeah, that's probably bad. You should fix that." :D

Quzah.
