I assumed it was clear to anyone checking that *all* the other exported
objects were *POINTERS*. It also makes sense that NT would export a
pointer, not the actual structure. Since when does an app export a whole
object?

DATA symbols are pointers, and that's exactly what I've done. In the
old code, the LpcPortObjectType was exported as a whole type instead.

Slightly different in the way you access the object, but both export the
pointer.

Eventually, yes, but right now I just want it to be able to build.
