From e246fe4cd9c292f4ef654f80d2eba676ff52f880 Mon Sep 17 00:00:00 2001 From: Brian Somers Date: Mon, 31 Mar 1997 22:51:00 +0000 Subject: Remove the syslog stuff, and allow various return values in uu_lock(). Add uu_lockerr() for turning the results of uu_lock into something printable. Remove bogus section in man page about race conditions allowing both processes to get the lock. Include libutil.h and use uu_lock() correctly where it should.
