Actually, I want socketpair(2). pipe(2) was what I used before

Umm, you want pipe(2), not socketpair(2).

Hi
A thing to keep in mind about the portal file system is that it
designed to provide a means of getting a file handle to an object that
could be obtained by a call to open(2). It does not then provide
a means of reading/writing etc. to that object.
If you take a look at the example portal.conf
I'd say it would be an excellent example of how to use portals if
nothing else, given that almost nobody understands them. :)

I need not remind you that file systems front-ending onto random protocols
are a bad idea for a huge number of reasons :-).
That said, you might take a look at Intermezzo, which someone has already
refered to indirectly in response to your e-mail -- Intermezzo is a file

I don't have a link handy, but if you search for it, I'm sure it's out
there. Linux had something like this called PerlFS which was much more
generic. The general gist of it was you could use it to make fs's of
things like http and ftp. It was extendable (I think) so you could make
your own fs han
