Yup, this is almost the same as what I was thinking.

"void *connection" won't work; you would then need to get a handle
for the internal representation of the endpoint out of libzmq when you
call connect() or bind(), in order to be able to call unbind() or
disconnect () on it.

I would go with just calling unbind() or disconnect()
with the char* you originally passed to bind() or connect().

Semantics are pretty much the same; it is obviously an error to unbind
() or disconnect() an endpoint which was not bound or connected in the
first place.
