@ -75,9 +75,9 @@ data transfer with the named id. This option applies only to the first
subsequent call to zmq_connect(), calls thereafter use default connection
behavior.
Typical use is to set this socket option on each zmq_connect() attempt
to a new host. Each connection should be assigned a unique name. Duplicated
names will trigger default connection behavior.
Typical use is to set this socket option ahead of each zmq_connect() attempt
to a new host. Each connection MUST be assigned a unique name. Assigning a
name that is already in use is not allowed.
Useful when connecting ROUTER to ROUTER, or STREAM to STREAM, as it
allows for immediate sending to peers. Outbound id framing requirements
