            <function>glGenQueries</function> returns <parameter>n</parameter> query object names in <parameter>ids</parameter>.
            There is no guarantee that the names form a contiguous set of integers;
            however, it is guaranteed that none of the returned names was in use
            immediately before the call to <function>glGenQueries</function>.

        <para>
            Query object names returned by a call to <function>glGenQueries</function> are not returned by
            subsequent calls, unless they are first deleted with

        </para>
        <para>
            No query objects are associated with the returned query object names until they are first used by calling
