Description NOKUBI Hirotaka 2000-10-21 07:00:01 UTC 
	Kldstat(2) man page saids it seems always returns 0, and kldstat(1)
	expects negative return value when some error condition occurs.
	It seems that klkstat() in src/sys/kern/kern_linker.c returns 0 on
	successful case, or some garbage on failed case (or, p_retval[0]'s
	initial value?).

Fix: 

I think kldstat(2) should return -1 when some error condition occurs.
	Kldnext(2) has same problem.

The man page no longer says what you describe, and from visual inspection 
it looks like the kldstat code does the right thing.  If you think this 
is still a problem, please file another PR with *a lot* more details.
