46    <div class="section">
47<p>Sets the callback invoked when POWER is pressed.</p><!-- write here --><P>
48This sets the callback that is called when POWER is pressed for just a short time.
49</P><P>
50A number of applet functions will not end until the process has left the callback, so promptly end the callback to reduce the risk of deadlock.
51</P><P>
52The application must close after the POWER Button is pressed. Call the <a href="../../../nn/applet/CTR/IsExpectedToCloseApplication.html"><CODE>nn::applet::CTR::IsExpectedToCloseApplication</CODE></a> function to check if the application must close.
