VERY EASY (traverse list) Question

FOXBAT asked
Last Modified: 2010-04-15
Hi im interested in learning C language. I have a linked list and a traverse list function that works fine.

void listTraverse(List list, PtrToActionFunc actfptr)
  ListNode *curr = list;                       /* ptr to current node */
   for (curr = list; curr != NULL; curr = curr->nextptr)
        actfptr(curr->dataptr);             /* do action to node's data */

As you can see it traverses the whole list in the loop.

How can I modify the function so that it will perform a (DeQueue) operation?

As in, when run, the function should only display info from the 1st node. When run again, displaying data from 2nd node, then 3rd and so on.
