        <para>
            <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

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

                        but no query objects are associated with the returned query object names until they are first used by calling
