You mean fake '.' and '..'?

Do you have any suggestions how to track state between calls?
I'm thinking about using global structure to track dev_t, ino_t and
off_t (and maybe handle), and if any of those changes since last exit
from the function consider it as a first call for this handle.

It looks like the best way would be to attach state to handle somehow
(that would be dropped automatically on CloseHandle), but I failed to
find a way to do so.
