Note that this gives direct access to the internal String buffer and should be used with care. In particular, you should never modify the string through the pointer returned. When you modify the String object, or when it is destroyed, any pointer previously returned by c_str() becomes invalid and should not be used any longer. <br /> <br /> <br /> &lt;font color=&quot;orange&quot; size=&quot;+1&quot;&gt;'''语法'''&lt;/font&gt;<br /> <br /> string.c_str() <br /> <br /> <br /> &lt;font color=&quot;orange&quot; size=&quot;+1&quot;&gt;'''参数'''&lt;/font&gt;<br /> <br /> none <br /> <br /> <br /> &lt;font color=&quot;orange&quot; size=&quot;+1&quot;&gt;'''返回值'''&lt;/font&gt;<br /> <br /> A pointer to the C-style version of the invoking string. <br /> <br /> <br /> ----<br /> <br /> [[String - object|返回String]]<br /> <br /> [[Arduino语法参考 | 返回Arduino语法参考列表]]<br /> <br /> 更多建议和问题欢迎反馈至 [http://www.yfrobot.com YFRobot论坛]</div>
