Specifies the integer name of the display list to be executed.
</dd></dl></div></div><div class="refsect1" lang="en"><a name="glCallList.3G-description"/><h2>Description</h2><p>
<tt>glCallList</tt> causes the named display list to be executed. The commands saved in the display list
are executed in order, just as if they were called without using a display list. If <i><tt>list</tt></i> has not
been defined as a display list, <tt>glCallList</tt> is ignored.
</p><p>
<tt>glCallList</tt> can appear inside a display list. To avoid the possibility of infinite recursion
resulting from display lists calling one another, a limit is placed on the nesting level of display lists during
display-list execution. This limit is at least 64, and it depends on the implementation.
</p><p>
GL state is not saved and restored across a call to <tt>glCallList</tt>. Thus, changes made to GL state
during the execution of a display list remain after execution of the display list is completed. Use <a href="glPushAttrib.3G.xml"><tt>glPushAttrib</tt></a>, <a href="glPushAttrib.3G.xml"><tt>glPopAttrib</tt></a>, <a href="glPushMatrix.3G.xml"><tt>glPushMatrix</tt></a>, and <a href="glPushMatrix.3G.xml"><tt>glPopMatrix</tt></a> to preserve GL
state across <tt>glCallList</tt> calls.
</p></div><div class="refsect1" lang="en"><a name="glCallList.3G-notes"/><h2>Notes</h2><p>
Display lists can be executed between a call to <a href="glBegin.3G.xml"><tt>glBegin</tt></a> and the corresponding
call to <a href="glBegin.3G.xml"><tt>glEnd</tt></a>, as long as the display list includes only commands that are
allowed in this interval.
