[zeromq-dev] Dealer send succeeded/failed

[Pieter Hintjens]

Erwin,

Sorry for the late reply, I'm at a conference. You will find numerous
examples that do what you need in Chapter 4 of the Guide. Heartbeating
is part of it, but there are other aspects too, such as failover and
retries. To properly build this you should work through the examples
until you understand each type of failure that can affect your
use-case, and how to detect it and deal with it.
