Sorry, I don't have a code example.

A refcursor data type is basically a string, containing the name of an 
open cursor (portal). It is stored binary compatible to the text data 
type. In the C function, you extract that name (using the textout 
function) and use it inside the FETCH query as the cursor name. You may 
need to double-quote that string.
