STANDARDS CONFORMANCE
The HP implementation does not return the
errno value [EOVERFLOW].
The POSIX standards leave some features to the implementing vendor to define. These features
are affected in the HP implementation:
• For files other than regular disk files, the st_size field of the stat structure is set to 0
(zero). For directories, st_size is set to 4096.
• The S_IRWXU, S_IRWXG, S_IRWXO, S_IFMT, S_ISVTX, S_NONSTOP,
S_ISGID, and S_ISUID bits are ORed into the st_mode field of the stat structure.
HP extensions to the XPG4 Version 2 specification are:
• The errno values [EFAULT], [EFSBAD], [EIO], [EISGUARDIAN], [ENETDOWN],
[ENOROOT], [ENXIO], and [EWRONGID] can be returned by the fstat() function.
