Returns all keys for the group name <em class="parameter"><code>group_name</code></em>.  The array of
returned keys will be <code class="literal">NULL</code>-terminated, so <em class="parameter"><code>length</code></em> may
optionally be <code class="literal">NULL</code>. In the event that the <em class="parameter"><code>group_name</code></em> cannot
be found, <code class="literal">NULL</code> is returned and <em class="parameter"><code>error</code></em> is set to
<span class="type">G_KEY_FILE_ERROR_GROUP_NOT_FOUND</span>.</p>
