NFS File identity resolution?

[Mayank Prakash]

--

Given a set of NFS servers and clients on the same network, and two
processes A and B on possibly different nodes, which can communicate
using sockets. How can the two processes determine if a file referred to
as "/a/b/c/file" by process A is really the file referred to as "/A/B/file"
by the process B? In other words, on the node of the process A, "/a/c/b"
could be mounted on X:/server/dir, and on the node of process B, "/A/B"
could be mounted on X:/server/dir. It is therefore not enough to compare
the directory parts alone. One must be able to determine which server
the file is coming from. [Essentially what the define command does, but
I want to do it from C].

Thanks.
