class Protection from OSD
|
|
|
|
---Purpose: This class provides data to manage file protection
|
|
-- Example:These rights are treated in a system dependent manner :
|
|
-- On UNIX you have User,Group and Other rights
|
|
-- On VMS you have Owner,Group,World and System rights
|
|
-- An automatic conversion is done between OSD and UNIX/VMS.
|
|
--
|
|
-- OSD VMS UNIX
|
|
-- User Owner User
|
|
-- Group Group Group
|
|
-- World World Other
|
|
-- System System (combined with Other)
|
|
--
|
|
-- When you use System protection on UNIX you must know that
|
|
-- Other rights and System rights are inclusively "ORed".
|
|
-- So Other with only READ access and System with WRITE access
|
|
-- will produce on UNIX Other with READ and WRITE access.
|
|
--
|
|
-- This choice comes from the fact that ROOT can't be considered
|
|
-- as member of the group nor as user. So it is considered as Other.
