<code class="function">glGenQueries</code> returns <em class="parameter"><code>n</code></em> query object names in <em class="parameter"><code>ids</code></em>.
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 <code class="function">glGenQueries</code>.
</p><p>
Query object names returned by a call to <code class="function">glGenQueries</code> are not returned by
subsequent calls, unless they are first deleted with
<a href="glDeleteQueries"><span class="citerefentry"><span class="refentrytitle">glDeleteQueries</span></span></a>.
</p><p>
No query objects are associated with the returned query object names until they are first used by calling
<a href="glBeginQuery"><span class="citerefentry"><span class="refentrytitle">glBeginQuery</span></span></a>.
