OSD_Protection Class Reference

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.

DEFINE_STANDARD_ALLOC OSD_Protection ()
 Initializes global access rights as follows

User : Read Write
System : Read Write
Group : Read
World : Read

 OSD_Protection (const OSD_SingleProtection System, const OSD_SingleProtection User, const OSD_SingleProtection Group, const OSD_SingleProtection World)
 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)
 Sets protection of 'World'

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
 Gets protection of 'World'

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.
