Detailed Description

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.
