Why set it to NULL and then set it to the instance right after this?
I think I was going with "not sure what *dest becomes if NewInstance" fails, and so I figured better safe than sorry. I'd rather have it NULL than undefined.

What about all the properties of the instance? This gets a new instance structure, yes, but all it has is an object path. Maybe that is all you need at the moment, but I don't think this does what other consumers of the library would think by the name :)
It should be easy to loop through all the properties and copy them over. It will look similar to the array copy/filter code in Kaitlin's libcmpiutil CO patch.
I'm pleading CIM ignorance on this one. I thought the ObjectPath encompassed the properties, and thought that my testing showed it happening (I don't manually move the JobState over but it is est), but I could have been wrong. -- -Jay
