Hello,
You can do this with XREP and PAIRs (or XREQs). Just set the IDENTITY of the
receivers with setsockopt, and send the same thing as the first part each
message from the XREP socket.
For instance:
(this is for Python bindings, but similar in C/C++)
addr = 'tcp://127.0.0.1:12345'
x = ctx.socket(XREP)
x.bind('tcp://127.0.0.1:12345')
a = ctx.socket(PAIR)
a.setsockopt(IDENTITY, 'a')
a.connect(addr)
b = ctx.socket(PAIR)
b.setsockopt(IDENTITY, 'b')
b.connect(addr)
x.send_multipart(['a', 'hi a', 'from x'])
x.send_multipart(['b', 'hi b')
a.recv_multipart()
[ 'hi a', 'from x' ]
b.recv()
'hi b'
You could also have symmetric p2p messaging through a central server if you
use a modified version of the Queue device with a single XREP socket that
swaps the first two parts of a multipart message (to get identity order
correct).
