STANDARDS CONFORMANCE
The POSIX standards leave some features to the implementing vendor to define. These features
are affected in the HP implementation:
• A process can change the value of the owner ID of a file only if the effective user ID of
the process gives the process appropriate privileges.
• Upon successful completion, the set-user-ID attribute (the S_ISUID bit) and the set-
group-ID attribute (the S_ISGID bit) of the file are always cleared.
• The error [EINVAL] can be detected.
HP extensions to the XPG4 Version 2 specification are:
• To change the file access permissions of a file or directory, the effective user ID of the |
process must match the super ID or the owner of the file, or the effective user ID or one |
of the group affiliations for the process must qualify the process for membership in the |
Safeguard SECURITY-OSS-ADMINISTRATOR group.
• The errno values [EFAULT], [EFSBAD], [EIO], [ENOROOT], [ENOTSUP], [ENXIO],
and [EOSSNOTRUNNING] can be returned.
