ZMQ_INVERT_MATCHING reverses the PUB/SUB prefix matching. The subscription list becomes a rejection list. The PUB socket sends messages to all connected (X)SUB sockets that do not have any matching subscription. Whenever the option is used on a PUB/XPUB socket, any connecting SUB sockets must also set it or they will reject everything the publisher sends them. XSUB sockets are unaffected because they do not filter out incoming messages.
ZeroMQ
Welcome
The 0MQ lightweight messaging kernel is a library which extends the standard socket interfaces with features traditionally provided by specialised messaging middleware products. 0MQ sockets provide an abstraction of asynchronous message queues, multiple messaging patterns, message filtering (subscriptions), seamless access to multiple transport protocols and more.
