 For each output generated, the control channel ''c'' will produce a 0 or 1 token depending on the choice made by the arbiter.
+===== Sink =====
+A dataflow sink simply receives and discards a token from a channel. Sinks are not needed in general, since the channel that corresponds to the sink can be optimized away by an implementation. However, sinks can be useful when a particular process is re-used in a context when one of its outputs is not used. The syntax is the following:
+<code>
+dataflow {
+   c -> *
+}
+</code>
+The values received on ''c'' are discarded by the sink.
