Any outstanding messages physically received from the network but not -yet received by the application with _zmq_recv()_ shall also be dropped. As for -the messages sent with _zmq_send()_ but not yet passed to the network, 0MQ -will try to send them in the background after _zmq_close()_ returns. Time spent -attempting can be set using _ZMQ_LINGER_ socket option. +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'. + +NOTE: The default setting of _ZMQ_LINGER_ does not discard unsent messages; +this behaviour may cause the application to block when calling _zmq_term()_. +For details refer to linkzmq:zmq_setsockopt[3] and linkzmq:zmq_term[3].
