In the general case you can't do it.  For example:
	char *p = "/tmp/mail1234";
	freopen(p, "r", stdin);
	unlink(p);
	...
(I've got some highly useful programs that do this.)

If you can get the major/minor device numbers, you can rummage around
to find the inode, then work back from that, but all this was hashed
out here about six months ago and the conclusion was: good luck, you
won't get them all.
