Review comment:
       Thanks for your elucidation.  I was mis-remembering my earlier attempts 
but your suggestion helped me track down why my earlier code had been failing 
the unit tests  (memory management in the non-NULL case).
   I have ended up with a slight variation on your suggestion due to a 
preference for single return points, but I think it is as efficient - and an 
improvement on my first submission.
