Not elegantly. You have to get the device and inode, then start from the root of the device and enumerate the directories, do a stat on each entry until you find a match.

And you can get multiple matches for the same inode as a single file can have multiple names.

Also, a file does not *have* to have a name, for instance if you create a file then unlink it before you close it you have a valid file descriptor but no name in the file system.

So a single file can have zero or many names.
