REMARKS

This entry describes the inode structure for the HFS file system.  Refer to other inode(4) manual pages for information valid for other implementations. 

DESCRIPTION

An inode for a plain file or directory in a file system has the following structure defined by <sys/ino.h>. 

/∗ Inode structure as it appears on a disk block ∗/

structdinode {
 u_shortdi_mode;/∗ mode and type of file ∗/
shortdi_nlink;/∗ number of links to file ∗/
shortdi_uid;/∗ owner’s user id ∗/
shortdi_gid;/∗ owner’s group id ∗/
quaddi_size;/∗ number of bytes in file ∗/
time_tdi_atime;/∗ time last accessed ∗/
longdi_atspare;
time_tdi_mtime;/∗ time last modified ∗/
longdi_mtspare;
time_tdi_ctime;/∗ time of last file status change ∗/
longdi_ctspare;
daddr_tdi_db[NDADDR]; /∗ disk block addresses ∗/
daddr_tdi_ib[NIADDR]; /∗ indirect blocks ∗/
longdi_flags;/∗ status, currently unused ∗/
longdi_blocks;/∗ blocks actually held ∗/
longdi_spare[5];/∗ reserved, currently unused ∗/
};

For the meaning of the defined types u_short, quad, daddr_t and time_t see types(5).

See /usr/include/sys/inode.h for the definition of inode structures for special files, pipes, or FIFO’s.
