 100 <p>The <code class="computeroutput"><a class="link" href="basic_string.html" title="Class template basic_string">basic_string</a></code> class provides a generic template for a dynamically- sized character sequence. This is most commonly used through the <code class="computeroutput">string</code> typedef (for <code class="computeroutput">basic_string&lt;char&gt;</code>).</p>
 101 <p>For example, to create a string on the device with its contents copied from a C-string on the host: </p>
