In current releases, a C function cannot return a set; the expression
evaluator has a hard-wired notion that only SQL-language functions can
return sets.
This is fixed in current development sources (7.1-to-be). How to do it
might even be documented by the time 7.1 gets out, though it's not yet
:-(
