 <h4 class="subsection">Mutex Type</h4> <p>A <em>mutex</em> is an exclusive lock that threads can own and disown, in order to synchronize between them. See <a href="mutexes">Mutexes</a>. </p> <p>Mutex objects have no read syntax. They print in hash notation, giving the name of the mutex (if it has been given a name) or its address in core: </p> <div class="example"> <pre class="example">(make-mutex "my-mutex")
    ⇒ #&lt;mutex my-mutex&gt;
(make-mutex)
    ⇒ #&lt;mutex 01c7e4e0&gt;
</pre>
