Bc2000 (for the BCF2000 & BCR2000)

I am working on a control surface plugin.

I have a desperate situation where I need to determine whether the change to a DAW widget came from spinning the widget in he DAW or if it was changed by spinning the encoder on the BCR. 

How do I peek in at an encoder's current value setting using BCL, C, or 
otherwise.

Thanks in advance.
