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 errors [EINTR], [EINVAL], and [EIO] can be detected.
HP extensions to the XPG4 Version 2 specification are:
• The errno values [EFSBAD], [EIO], [ENOROOT], and [EOSSNOTRUNNING] can be
returned.
