Generaly, maping inode to filename is not unique, since inode (except directory inodes) can have zero to many names. Each inode has a list of dentries. These can be converted. A dentry can be converted to a name by reverse-walking the tree. You have a dentry, read it's name and follow the pointer to it's parent. You should look how the symlinks /proc/<pid>/fs/* are generated (somewhere in fs/proc/). ------------------------------------------------------------------------------- Jan 'Bulb' Hudec <bulb@ucw.cz> -- Kernelnewbies: Help each other learn about the Linux kernel.
