Returning tuple(s) from C-Functions

Hi.

I'm into programming a function for pg for searching a ldap directory.
But this whole effort has absolutely no sense, if i don't find a way to
return _at least_ one whole tuple from a C-Function, e.g.

create function foobar(footable)
    returns bartable
    as '/var/lib/pgsql/data/foobar.o'
    language 'c'
;

and i return a pointer to a tuple or something?

This is what the FAQ says about it:

5.3) How do I write a C function to return a tuple?

This requires wizardry so extreme that the authors have never tried it,
though in principle it can be done?

Is this answer still correct? Is there a way to do it with 7.1?
Can i write to a temporary table in this function and insert into the
backend somehow?
I'm not expecting too much people having this done, but if anyone did
it, please reply...

tia,
Philip
