Description

The C++ binding needs a disciplined and effective way to handle protocol (and transport) errors.

Currently the API has some error events, however if they are not handled the program will just hang - it would be better in this case to throw an exception so that the program doesn't just hang.

Another issue is creating error states (attaching a condition) when closing a connection/session/link - there should be some straightforward way to indicate the error to your peer.
