37<h2>Description</h2>
38    <div class="section">
39<p>Sets the exit callback for the current command list.</p><P>
40When the command request specified by the <CODE>nngxEnableCmdlistCallback</CODE> function finishes, <SPAN class="argument">func</SPAN> is called. The callback function receives as an argument the number of the accumulated command that finished executing.
41            </P><P>
42Note that the command list is still executing when this callback is invoked by the completion of last of the accumulated commands. Thus, unlike with the <CODE>nngxClearCmdlist</CODE> function, you cannot use functions inside the callback that cannot be called for the executing command list.
43            </P><P>
44This function generates the following errors.
45<TABLE><TR><TH>GL_ERROR_8010_DMP</TH><TD>The current command list is running.</TD></TR></TABLE></P></div>
