DECLARE
I INTEGER;
BEGIN
SELECT *
INTO I
FROM foo( <tablename> )
That part is easy, but I don't understand what you are using as a function
parameter.

SELECT foo(tablename) FROM tablename;
or
SELECT foo(tablename.*) FROM tablename;
The first is traditional Postgres usage, but I think the second makes it
more clear what's going on.
BTW, if you use a table alias then the alias is the name to refer to.
SELECT foo(x.*) FROM tablename as x;
