I can't help because I don't understand union {}

>2) can i access %str(result) or should I be doing something else.

I would say you should be doing something else.  "result" is a pointer to
something.  You need to create a space for that something, just as you have
for pdu_ds.  The function returns a pointer and that pointer points to the
pdu_ds memory space.  Since I don't know what union {} does, I can't tell
you what sort of space to create; perhaps another data structure?  Then you
could address the data being pointed to by "result."
