Getting the pathname from a FILE*.

[Karl Berry.]

The title says it all. Am I missing something obvious?
The pathname doesn't seem to be a field in either the
_iobuf or the structure returned by stat.
ttyname or ctermid will give you the pathname
of your terminal, but I want the pathname of an
arbitrary FILE* I have fopen. Or am I missing some
reason why this is not feasible?

Karl.
