+ <h3 class="section">Predicates on Markers</h3>   <p>You can test an object to see whether it is a marker, or whether it is either an integer or a marker. The latter test is useful in connection with the arithmetic functions that work with both markers and integers. </p> <dl> <dt id="markerp">Function: <strong>markerp</strong> <em>object</em>
+</dt> <dd><p>This function returns <code>t</code> if <var>object</var> is a marker, <code>nil</code> otherwise. Note that integers are not markers, even though many functions will accept either a marker or an integer. </p></dd>
