Different philosophy is fine.

But why doesn't ZMQ report connection errors?
When 'Connection refused' (ECONNREFUSED),  'Operation timed out' (ETIMEDOUT) or several other relevant error conditions arise they should be reported to the user. Why aren't they reported?

The connection will not be performed immediately but as needed by ØMQ. Thus a successful invocation of /zmq_connect()/ does not indicate that a physical connection was or can actually be established.


ZMQ sockets are not TCP sockets. There is an unfortunate overloading of terms, and what you think you know may not apply to ZMQ. Go back and read https://zguide.zeromq.org/docs/chapter2/#The-Socket-API where this is described in some detail.
