11 * print_e2fsck_message() prints a message to the user, using
12 * compression techniques and expansions of abbreviations.
14 * The following % expansions are supported:
16 * %b <blk> block number
17 * %B <blkcount> interpret blkcount as blkcount
18 * %c <blk2> block number
19 * %Di <dirent>->ino inode number
20 * %Dn <dirent>->name string
21 * %Dr <dirent>->rec_len
22 * %Dl <dirent>->name_len
23 * %Dt <dirent>->filetype
24 * %d <dir> inode number
26 * %i <ino> inode number
27 * %Is <inode> -> i_size
28 * %IS <inode> -> i_extra_isize
29 * %Ib <inode> -> i_blocks
30 * %Il <inode> -> i_links_count
31 * %Im <inode> -> i_mode
32 * %IM <inode> -> i_mtime
33 * %IF <inode> -> i_faddr
34 * %If <inode> -> i_file_acl
35 * %Id <inode> -> i_size_high
36 * %Iu <inode> -> i_uid
37 * %Ig <inode> -> i_gid
39 * %j <ino2> inode number
40 * %m <com_err error message>
42 * %p ext2fs_get_pathname of directory <ino>
43 * %P ext2fs_get_pathname of <dirent>->ino with <ino2> as
44 * the containing directory. (If dirent is NULL
45 * then return the pathname of directory <ino2>)
46 * %q ext2fs_get_pathname of directory <dir>
47 * %Q ext2fs_get_pathname of directory <ino> with <dir> as
48 * the containing directory.
49 * %r <blkcount> interpret blkcount as refcount
50 * %s <str> miscellaneous string
53 * %U quota type (in <num>)
54 * %S backup superblock
55 * %X <num> hexadecimal format
57 * The following '@' expansions are supported:
59 * @a extended attribute
64 * @C conflicts with some other fs block
68 * @E Entry '%Dn' in %p (%i)
