This was indeed the impression I got. With reference to my original
questions regarding its use, perhaps you could suggest some way to
actually use this API then, in order to solve my problem?
Unless there's some subtle detail or trick I have misunderstood, it
doesn't appear to be easily possible in this manner.
How would you suggest I manage these pointers and data structures?
I don't think it was thought of in the context of reference counted items.
you could use an ever increasing number that you hash on a hash table.
if the kernel returns a number that is out of date you won't find it
and you
can ignore it. If the kernel returns a number you are currently tracking.
then you use the item associated with that entry.
