@hackage mDNSResponder-client1.0.3

On OS X, iOS, and Bonjour for Windows, mDNSResponder is the daemon responsible for providing the Bonjour services. This is a client implementation directly on top of the (not documented outside of the open source code) Unix domain socket protocol, as the "low level" dns_sd C API provided by Apple relies on heavy use of callbacks and does not allow for nonblocking connections.
