li><p>A synchronous, bounded channel. The <code>sync_channel()</code> function will return
a <code>(SyncSender, Receiver)</code> tuple where the storage for pending messages
is a pre-allocated buffer of a fixed size. All sends will be
<strong>synchronous</strong> by blocking until there is buffer space available. Note
that a bound of 0 is allowed, causing the channel to become a
&quot;rendezvous&quot; channel where each sender atomically hands off a message to
a receiver.</p></li>
