	FreeBSD sassaby.nokubi.or.jp 5.0-CURRENT FreeBSD 5.0-CURRENT #6: Fri Sep 15 18:57:36 JST 2000     root@:/usr/src/sys/compile/SASSABY  i386

>Description:

	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?).

>How-To-Repeat:

	

>Fix:

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