Doug:

Personally, I simply wouldn't use that particular API until I had 
to. If you want partitioning data, you can call the _MATMATR1 
builtin to get a bunch of info.

http://publib.boulder.ibm.com/infocenter/iseries/v5r4/index.jsp?topic=/rzatk/MATMATR.htm
or
http://tinyurl.com/6jq8ky

This is easy enough to call even from ILE CL and it works on V5R2 
and at least some earlier releases.

Naturally, if dlpar_get_info provides data that _MATMATR1 does not, 
you're stuck. I've used dlpar_get_info on V5R3 and above, but only 
for some general info.
