Hi Richard,
Thanks for your answer. I already receive the address but in the particular
case of a router socket it's not that useful. I receive something like
'tcp://0.0.0.0:2000' which is the address to which the socket is bound.
My question was if there is a way to know what is the identity of the peer that
has been disconnected (as set on the client side with the ZMQ_IDENTITY option).
There are many connections behind a router. When I receive a disconnect event I
need to know to which connection it belongs in order to take the correct action
on the server (callback user code, cleanup resource, ..).
Cheers,
Joel.

Hi Joel,
The monitor event mechanism uses 2 sends to communicate, the first message
contains the event details and fd, the second will contain the address, so
you need to do a second receive to get the address.
Apparently this was to make it easier for language bindings.

Hi,
Currently I'm trying to setup a monitor on a ROUTER socket to detect clients
disconnections. This system is put in place in addition to an heartbeat
mechanism in order to provide faster disconnection detection on the server side.
My problem now is that I effectively receive a ZMQ_EVENT_DISCONNECTED event
from ZMQ, but the payload of this event only contains "fd" (file
descriptor I guess?). In such case is there a way to find the identity of the
peer (as set on the client side using the ZMQ_IDENTITY option)?
