-argument. 
+argument. Any outstanding messages physically received from the network but not
+yet received by the application with _zmq_recv()_ shall be discarded. The
+behaviour for discarding messages sent by the application with _zmq_send()_ but
+not yet physically transferred to the network depends on the value of the
+_ZMQ_LINGER_ socket option for the specified 'socket'.
 
 The 'endpoint' argument is as described in linkzmq:zmq_connect[3]
 
+NOTE: The default setting of _ZMQ_LINGER_ does not discard unsent messages;
+this behaviour may cause the application to block when calling _zmq_term()_.

 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 The 'ZMQ_LINGER' option shall set the linger period for the specified 'socket'.
 The linger period determines how long pending messages which have yet to be
-sent to a peer shall linger in memory after a socket is closed with
