31 | //! This class provides data to manage file protection |
32 | //! Example:These rights are treated in a system dependent manner : |
33 | //! On UNIX you have User,Group and Other rights |
34 | //! On VMS you have Owner,Group,World and System rights |
35 | //! An automatic conversion is done between OSD and UNIX/VMS. |
36 | //! |
37 | //! OSD VMS UNIX |
38 | //! User Owner User |
39 | //! Group Group Group |
40 | //! World World Other |
41 | //! System System (combined with Other) |
42 | //! |
43 | //! When you use System protection on UNIX you must know that |
44 | //! Other rights and System rights are inclusively "ORed". |
45 | //! So Other with only READ access and System with WRITE access |
46 | //! will produce on UNIX Other with READ and WRITE access. |
47 | //! |
48 | //! This choice comes from the fact that ROOT can't be considered |
49 | //! as member of the group nor as user. So it is considered as Other. |
