Return from incompatible pointer type

I have a struct:

Code:

---

typedef int DATA;
typedef struct node {
struct node *next;
DATA digit;
} NODE;

typedef struct {
struct node *head;
int size; // number of elements in the list
} LIST_HEAD;

---

I write reverseList fuction to reverses the order of the elements in the list, return a pointer to head of the reversed list.
Everything seem works fine, but I get the [Warning] return from incompatible pointer type at the return line. Please help to indicate my problem in this code. Thank you.

Code:

---

LIST_HEAD *reverseList(LIST_HEAD *list)       
  NODE  *p,*q,*r;
        p=list->head;
        q=NULL;

        while(p!=NULL)
        {
            r=q;
            q=p;
            p=p->next;
            q->next=r;
        }
        p = q;
        list->head=p;
        return p; //error here
}

You are returning *p, a pointer to a NODE. The way your function is declared, it wants to return a pointer to a LIST_HEAD. Typically your head node is not a different struct than regular nodes, and will contain data.

Thanks for quick reply. So I realize that I should return list . I'll try it.
