<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 class="citerefentry" 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 class="citerefentry" href="glBeginQuery"><span class="citerefentry"><span class="refentrytitle">glBeginQuery</span></span></a>.

</p></div><div class="refsect1" title="Notes"><a id="notes"></a><h2>Notes</h2><p>

<code class="function">glGenQueries</code> is available only if the GL version is 1.5 or greater.

</p></div><div class="refsect1" title="Errors"><a id="errors"></a><h2>Errors</h2><p>

<code class="constant">GL_INVALID_VALUE</code> is generated if <em class="parameter"><code>n</code></em> is negative.

</p><p>

<code class="constant">GL_INVALID_OPERATION</code> is generated if <code class="function">glGenQueries</code> is executed

between the execution of <a class="citerefentry" href="glBegin"><span class="citerefentry"><span class="refentrytitle">glBegin</span></span></a> and the corresponding

execution of <a class="citerefentry" href="glEnd"><span class="citerefentry"><span class="refentrytitle">glEnd</span></span></a>.
