Creating and removing directory entries
---------------------------------------

 - Function: errcode_t ext2fs_link (ext2_filsys FS, ext2_ino_t DIR,
          const char *NAME, ext2_ino_t INO, int flags)
     This function adds a new directory entry to the directory DIR,
     with NAME and INO specifying the name and inode number in the
     directory entry, respectively.

     The low 3 bits of the flags field is used to specify the file type
     of inode:   (No other flags are currently defined.)

    `EXT2_FT_UNKNOWN'
          The file type is unknown.

    `EXT2_FT_REG_FILE'
          The file type is a normal file.

    `EXT2_FT_DIR'
          The file type is a directory.

    `EXT2_FT_CHRDEV'
          The file type is a character device.

    `EXT2_FT_BLKDEV'
          The file type is a block device.

    `EXT2_FT_FIFO'
          The file type is a named pipe.

    `EXT2_FT_SOCK'
          The file type is a unix domain socket.

    `EXT2_FT_SYMLINK'
          The file type is a symbolic link.


 - Function: errcode_t ext2fs_unlink (ext2_filsys FS, ext2_ino_t DIR,
          const char *NAME, ext2_ino_t INO, int FLAGS)
     This function removes a directory entry from DIR.  The directory
     entry to be removed is the first one which is matched by NAME and
     INO.  If NAME is non-NULL, the directory entry's name must match
     NAME.  If INO is non-zero, the directory entry's inode number must
     match INO.  No flags are currently defined for `ext2fs_unlink';
     callers should pass in zero to this parameter.
