This function starts a communication node at the machine on which it is run. The communication node exists as a message queue running on a separate thread. Received messages are stored in a local queue and may be retrieved via the receive function.

start(address = NULL, port = 0L, threads = getOption("orcv.cores", 4L))

Arguments
