Um. Well, the arg is not a TupleTableSlot * anymore, so this is guaranteed to fail. This isn't part of what I thought the documented
SRF API was though.
I'm sure you're correct. The SRF API was for user defined functions, not procedural languages anyway. I'll look at how the other procedural languages handle tuple arguments.
If you take the arg[i] value and pass it to GetAttributeByName or GetAttributeByNum it will work (with some compiler warnings) and AFAICS we never documented more than that.
OK, thanks,
Joe
