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.

Sets values of fields | |
void | Values (OSD_SingleProtection &System, OSD_SingleProtection &User, OSD_SingleProtection &Group, OSD_SingleProtection &World) |
Retrieves values of fields | |
void | SetValues (const OSD_SingleProtection System, const OSD_SingleProtection User, const OSD_SingleProtection Group, const OSD_SingleProtection World) |
Sets values of fields | |
void | SetSystem (const OSD_SingleProtection priv) |
Sets protection of 'System' | |
void | SetUser (const OSD_SingleProtection priv) |
Sets protection of 'User' | |
void | SetGroup (const OSD_SingleProtection priv) |
Sets protection of 'Group' | |
void | SetWorld (const OSD_SingleProtection priv) |

OSD_SingleProtection | System () const |
Gets protection of 'System' | |
OSD_SingleProtection | User () const |
Gets protection of 'User' | |
OSD_SingleProtection | Group () const |
Gets protection of 'Group' | |
OSD_SingleProtection | World () const |

void | Add (OSD_SingleProtection &aProt, const OSD_SingleProtection aRight) |
Add a right to a single protection. ex: aProt = RWD me.Add(aProt,X) -> aProt = RWXD | |
void | Sub (OSD_SingleProtection &aProt, const OSD_SingleProtection aRight) |
Subtract a right to a single protection. ex: aProt = RWD me.Sub(aProt,RW) -> aProt = D But me.Sub(aProt,RWX) is also valid and gives same result. |
