On Linux, it's returned in the d_off field.

Googling around....  the NetBSD manpage doesn't mention any d_off field,
but it does have this:


	The current position pointer may be set and retrieved by
	lseek(2).  The current position pointer should only be set to a
	value returned by lseek(2), or zero.

So maybe that's what you want.
