You don't want to do this.  If the file's link count is more than one,
you can't do it at all, and even if the file's link count is equal to
one, you'd have to search the whole file system to get the right
filename.  Even assuming you know that FILE *foo is actually a file and
not a pipe, socket, etc.

(This is actually a comp.unix.* question.)

I would bring back hanging, and go into rope.  I would cut off the more
disreputable parts of the body and use the space for playing fields.
