<h2>Description</h2>
<p>
<code class="function">glPopDebugGroup</code> pops the active debug group.
After popping a debug group, the GL will also generate a debug
output message describing its cause based on the <em class="parameter"><code>message</code></em>
string, the source <em class="parameter"><code>source</code></em>, and an ID <em class="parameter"><code>id</code></em>
submitted to the corresponding <a class="citerefentry" href="glPushDebugGroup.xhtml"><span class="citerefentry"><span class="refentrytitle">glPushDebugGroup</span></span></a>
command. <code class="constant">GL_DEBUG_TYPE_PUSH_GROUP</code> and <code class="constant">GL_DEBUG_TYPE_POP_GROUP</code>
share a single namespace for message <em class="parameter"><code>id</code></em>.
<em class="parameter"><code>severity</code></em> has the value <code class="constant">GL_DEBUG_SEVERITY_NOTIFICATION</code>. The <em class="parameter"><code>type</code></em>
has the value <code class="constant">GL_DEBUG_TYPE_POP_GROUP</code>. Popping a debug group restores
the debug output volume control of the parent debug group.
</p>

<div class="refsect1" id="errors">
<h2>Errors</h2>
<p>
<code class="constant">GL_STACK_UNDERFLOW</code> is generated if an attempt is made to pop the default debug
group from the stack.
