            Bug ID: 216872
           Summary: Behavior for hsearch_r is flip-flopped per
                    documentation (behavior matches Linux, docs match
                    NetBSD)
           Product: Base System
           Version: CURRENT
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Some People
          Priority: ---
         Component: bin
          Assignee: freebsd-bugs@FreeBSD.org
          Reporter: ngie@FreeBSD.org

It seems that we grabbed the manpages for hcreate*(3) from NetBSD, but the
actual implementation is patterned after Linux. In particular,
.../contrib/netbsd-tests/lib/libc/stdlib/t_hsearch.c tests that text code f=
rom
a non-existent item when action=3DFIND, but the value it tests it against i=
s 1
(Linux -> non-zero -> error), not 0 (NetBSD -> zero -> error). I opened a b=
ug
for the non-intuitive behavior on NetBSD here:
http://gnats.netbsd.org/cgi-bin/query-pr-single.pl?number=3D51957 .

The documentation should match the implementation, at bare minimum. Whether=
 or
not the implementation matches Linux or NetBSD is a point of debate.
