<h2>Syntax</h2>
<dl>
<dt>(room [<i>info</i>])</dt>
<dd><i>info</i> - an optional, unused expression<br>
returns - <a href="nil.htm">NIL</a></dd>
</dl>
<h2>Description</h2>
<p>The 'room' function prints the current memory statistics to
<a href="global-standard-output.htm">*standard-output*</a>.
<a href="nil.htm">NIL</a> is always returned. The message shows
the statistics for:</p>
<ul>
<li><nobr>total nodes</nobr></li>
<li><nobr>current free nodes</nobr></li>
<li><nobr>current number of allocated memory segments</nobr></li>
<li><nobr>node size of the allocated memory segments</nobr></li>
<li><nobr>total memory in bytes</nobr></li>
<li>total number of garbage collections that have occured
since this session of XLISP started</li>
</ul>
<h2>Examples</h2>
<pre class="example">
(room) <font color="#008844">; prints Nodes: 4000</font>
<font color="#008844">; Free nodes: 1723</font>
<font color="#008844">; Segments: 4</font>
<font color="#008844">; Allocate: 1000</font>
<font color="#008844">; Total: 52566</font>
<font color="#008844">; Collections: 8</font>
<font color="#008844">; returns NIL</font>
</pre>
<p><b>Common Lisp:</b> In Common LISP, the 'info' argument controls the
amount of information that is printed. In Common Lisp, the form of and
information provided by the 'room' output is implementation dependent. For
portability, you should not count on this information or form.</p>
<p>See the
<a href="../manual/xlisp-man-031.htm#room">room</a>
function in the <nobr>XLISP 2.0</nobr> manual.</p>
