I think your PUB from the second publisher went to the first publisher
at the other end of the pipe ?
You might try using a device() to connect two sets of sockets back-to-
back, just like the server example.
I believe you'd do something like
create "inproc://pubsource"
device:
bind as a SUB
subscribe to all ("")
publishers:
connect as a PUB
on the other side:
device:
bind as a PUB
subscribers
connect as a SUB
subscribe to all ("")
I think the "one way" device can be used as a model, you're only going
one way :-)

I call bind only once. The second time I use connect and it returns 0.

I have a scenario when I need to use PUB/SUB scheme with multiple
publishers. Is it possible to do with "inproc" transport?
Here is what I tried:
- create PUB socket and bind it to "inproc://pipe" endpoint
- create another PUB socket and connect it to the same "inproc://
pipe" endpoint
- create SUB socket for each subscriber and connect them to thre
"inproc://pipe" endpoint.
- publish message using second publisher.
I'm getting no error, but message is not getting delivered to
subscribers. Am I doing something wrong?
I don't think it is possible to have multiple sockets bind to the
same endpoint. Are you certain that the result code from calling
bind is 0? If it is, then this is likely a bug and should be
reported (with sample code).
Alternately, if you are running this on Windows then I don't think
inproc or ipc transports are supported on that platform. That should
also error out (if you are on Windows).
