cfunction (net/address host port &opt type) Look up the connection information for a given hostname, port, and connection type. Returns a handle that can be used to send datagrams over network without establishing a connection. On Posix platforms, you can use :unix for host to connect to a unix domain socket, where the name is given in the port argument. On Linux, abstract unix domain sockets are specified with a leading '@' character in port.
