On top of which, ACLs suffer the same illness of any stat-based checking, insofar as checks against them are only an approximation to reality, potentially full of race conditions. It's really the OS that's going to do the ACL checking, and it'll do it when you do the actual operation, not the stat() call. Arguably a "correct" way to program is to ignore stat-like stuff entirely and just try to do the thing you want to do, and be prepared for the OS to reject it--which you should have been prepared for anyway... (Of course, fstat() does help with some of the race conditions by intentionally "losing" the race, as it were.) Larry
