Crocket, You've not explained what your case is but I assume you're trying to start the publisher and subscriber at the same time? You can try for instance connecting the pub socket to the sub socket rather than the other way around. The connecting side can start sending immediately.
In more general cases, the publisher starts much earlier than the subscribers, which will come and go at arbitrary moments. So you can use a variety of schemes to recover state, or simply not need it. Finally, if you want more delivery guarantees you might use other socket types, e.g. push/pull. Please do read the Guide, it has lots more explanation on this. -Pieter On Sat, Feb 23, 2013 at 2:27 AM, crocket <[email protected]> wrote: > There is no specific use case yet.
