Connecting to Blender... returns?

mtl1

I'm scripting something from DS to Blender, but I'm having issues trying to figure out how to pass communication between the two.

To be more specific, I want to return an acknowledgment from Blender when something has been completed, but I can't find anything in the DS SDK that would listen to the Blender process. Is there a function that allows me to do this?

Alternatively, I could get around this by checking if the Blender process is running, and quit Blender each time something has finished, but that seems very inefficient.
