pHILE+ System Calls stat_f
Return Value
This structure cannot be packed. mode_t, ino_t, dev_t, nlink_t,
uid_t, gid_t, off_t, and time_t are defined as unsigned long in
. The following differences exist for local file systems
(pHILE+, MS-DOS, and CD-ROM):
rdev = dev, nlink = 1, uid = 0, gid = 0, atime = ctime
= mtime
The status information word st_mode contains the following bits:
_IFMT 0170000 /* type of file */
_IFIFO 0010000 /* fifo special */
_IFCHR 0020000 /* character special */
_IFDIR 0040000 /* directory */
_IFBLK 0060000 /* block special */
_IFREG 0100000 /* regular file */
_IFLNK 0120000 /* symbolic link */
_IFSOCK 0140000 /* socket */
S_ISUID 0004000 /* set user ID on execution */
S_ISGID 0002000 /* set group ID on execution */
S_ISVTX 0001000 /* save swapped text even after use */
S_IRUSR 0000400 /* read permission, owner */
S_IWUSR 0000200 /* write permission, owner */
S_IXUSR 0000100 /* execute/search permission, owner */
S_IRGRP 0000040 /* read permission, group */
S_IWGRP 0000020 /* write permission, group */
S_IXGRP 0000010 /* execute/search permission, group */
S_IROTH 0000004 /* read permission, other */
S_IWOTH 0000002 /* write permission, other */
S_IXOTH 0000001 /* execute/search permission, other */
