[newbie] Linked list problem

Hi again,

just one question: How can I read a kernel double linked list in reverse
order?
Or, better to say, how can I access the 'last' (the item that linkes to the
head again) item, if all I got is a pointer to the head?

I've tried this one, but it doesn't seem to work:
lastitem = CONTAINING_RECORD(DoubleHead.Blink,MYSTRUCT, linkfield);

Any ideas?

Thanks a lot
Peter

that should work, you need to check if the list is not empty first though,
ie

if (IsListEmpty(&DoubleHead) == FALSE) {
lastitem = CONTAINING_RECORD(DoubleHead.Blink,MYSTRUCT, linkfield);
}
