Thread: Poiter to a pointer

What is the problem with my display function....

Code:

/*PROGRAM TO IMPLEMENT DIFFERENT OPERATIONS ON LINKED LISTS
*/
#include<stdio.h>
#include<stdlib.h>
#define draw for(i = 0 ;i<70;++i)printf(" ");
int flag_error = 0;

struct list
        {
                int num;
                struct list *link;
        };
typedef struct list node;

void display(node **p)
{
        node **temp = p;
        while(*temp != NULL)
        {
                printf("%d ->",*temp->num);

        } 

}
main()
{
         node * head;
        //MENU//
        //while(1)
        {       
                flag_error = 0;
                int i;
                system("clear");
                draw
                printf("-----------------------------\n\n\n");
                draw

 printf("      3 : DELETE ELEMENT \n");
                draw
                printf("      4 : DISPLAY LIST \n");

                        scanf(" %c",&ch);
                        if( ch != 'y' || ch != 'Y' )
                       return 0;
                }
        }
}

when I compile,the compiler says "error: request for member ‘num’ in something not a structure or union" about the statement " printf("%d ->",*temp->num);"
