        <para>
            The name stack is used during selection mode to allow sets of rendering
            commands to be uniquely identified.
            It consists of an ordered set of unsigned integers.
            <function>glInitNames</function> causes the name stack to be initialized to its default empty state.
        </para>
        <para>
            The name stack is always empty while the render mode is not <constant>GL_SELECT</constant>.
            Calls to <function>glInitNames</function> while the render mode is not <constant>GL_SELECT</constant> are ignored.
