Hi all, I'm looking at using avahi (eg, zeroconf) with a zeromq based application. I'd like to be able to have zeromq bind to any free port so that I can announce the service via avahi, but afaict the string passed to zmq_bind must have a port number. Is there any way to avoid specifying a TCP port number and just have one automatically assigned?
Apparently you can "just create the socket and call listen() on it. Then, the IP stack will automatically assign a free port number. Use getsockname() to query the port number that has been chosen and use that when registering the Avahi service." I tried using an address string of "tcp://lo" without success (eg, zmq_bind (socket, "tcp://lo")). There is an example at the link below that shows how this is done with normal sockets: http://git.0pointer.de/?p=avahi.git;a=blob;f=docs/socket-auto-port.c;h=75dffafe75f35c0aa2143e62f16ba8aa1c2804de;hb=HEAD -Dave _______________________________________________ zeromq-dev mailing list [email protected] http://lists.zeromq.org/mailman/listinfo/zeromq-dev
