STREAMS programming question, Data Link layer

I'm trying to find out how to access the minor number returned by
a clone open call of a STREAMS device driver. In particular, I've gone
through the ATT SV/386 3.2 STREAMS programmers guide and made a kernel
with the loopback example driver.
This is a clonable driver, and it's properly called with the CLONEOPEN
flag. It also allocates a unused minor number.
There's no user-level example which shows how to get at the minor number.
I tried fstat() on the open file, but that gives me the same minor number
on two different clone opens. What's the canonical way to do this?
thanks for any hint,
-michael
