Structurally, FAT does not have inodes or hard links.
Consequently, the inode numbers in a stat() implementation over FAT
don't have the semantics of inode identifiers.
So for instance "tmp" and "tmp/." are different objects, not merely
different directory entries pointing at the same inode as they would be
in a UNIX-like filesystem.
By the way, you can investigate inode numbers using the -i option
of ls instead of hacking up your own C program.
$ mkdir tmp
$ ls -din tmp tmp/.
