<h2>Description<a class="headerlink" href="#description" title="Link to this heading"></a></h2>
<p>The <code class="docutils literal notranslate"><span class="pre">ProfileIOGroup</span></code> class is a derived implementation of <a class="reference internal" href="geopm%3A%3AIOGroup.3.html"><span class="doc">geopm::IOGroup(3)</span></a> that provides signals from the application.
Consequently, it inherits and overrides many of the methods of the <code class="docutils literal notranslate"><span class="pre">IOGroup</span></code> class.
These overridden methods are described in the <code class="docutils literal notranslate"><span class="pre">IOGroup</span></code> man page.
Only the methods unique to the <code class="docutils literal notranslate"><span class="pre">ProfileIOGroup</span></code> class are described here.</p>
<p>For more details, see the doxygen
page at <a class="reference external" href="https://geopm.github.io/geopm-runtime-dox/classgeopm_1_1_profile_i_o_group.html">https://geopm.github.io/geopm-runtime-dox/classgeopm_1_1_profile_i_o_group.html</a>.</p>
