That's exactly what I said :)

You may be right, however that's not what my spec says:
when you disconnect you are disconnecting a SET of endpoints.

This is because connect/bind can be called with a char* to a buffer
which can be memcpy() into with the end point name. So all such
endpoints have the same char* address.

So since you're disconnecting a SET .. well there's nothing wrong
with an empty set!

Instead, the number of matched endpoints is returned by the function.
The client can then decide if 0 is an error  or not.
