They all compare property names using <code>eq</code>. </p> <dl> <dt id="plist-get">Function: <strong>plist-get</strong> <em>plist property</em> -</dt> <dd> -<p>This returns the value of the <var>property</var> property stored in the property list <var>plist</var>. It accepts a malformed <var>plist</var> argument. If <var>property</var> is not found in the <var>plist</var>, it returns <code>nil</code>. For example, </p> <div class="example"> <pre class="example">(plist-get '(foo 4) 'foo) - ⇒ 4 -(plist-get '(foo 4 bad) 'foo) - ⇒ 4 -(plist-get '(foo 4 bad) 'bad) - ⇒ nil -(plist-get '(foo 4 bad) 'bar) - ⇒ nil -</pre> -</div> </dd> -</dl> <dl> <dt id="plist-put">Function: <strong>plist-put</strong> <em>plist property value</em> -</dt> <dd> -<p>This stores <var>value</var> as the value of the <var>property</var> property in the property list <var>plist</var>. It may modify <var>plist</var> destructively, or it may construct a new list structure without altering the old. The function returns the modified property list, so you can store that back in the place where you got <var>plist</var>.
