Deleting - Linked List

[TeeTee]

I have created a double linked list program, where I can add and display the detail in the list.

However, I need to delete the last item in the list without having to identify any value. Is this possible? Or do I have to search the link with the value.

I have tried *last = NULL;
& *last = info->prior;

Can anyone provide the general coding?

... is this what you're asking for?

void delLast ()
{
 node * p = last -> prior;
 p -> next = NULL;
 free (last);
 last = p;
}

or if last isn't global...

void delLast (node **last)
{
 node *p = *last -> prior;
 p -> next = NULL;
 free (*last);
 *last = p;
}

As always, no promises that it'll compile... or that it's what you're looking for. The free() s could be left out I suppose, and it would have the same noticable effect, although that is a big no-no.
