<h2>12.4 glutCloseFunc</h2> <h2>12.4 glutCloseFunc</h2>
<p>
The <tt>glutCloseFunc</tt> function sets the window's close
callback. <i>Freeglut</i> calls the close callback when the window is
about to be destroyed.
</p>
<p><b>Usage</b></p>
<p><tt>void glutCloseFunc ( void (*func) ( void ) );</tt> </p>
<p><tt>func </tt>The window's new closure callback function <br/>
</p>
<p><b>Description</b></p>
<p>
The <tt>glutCloseFunc</tt> function specifies the function
that <i>freeglut</i> will call when a window is about to be closed,
either because it is requested using <tt>glutDestroyWindow</tt>,
because the user clicked on the "x" in the window header
(for top-level windows only), or due to a pending closure of a
subwindow's parent window. In the first case, the closure callback
is not invoked from the <tt>glutDestroyWindow</tt> call, but at a
later time point.
<i>Freeglut</i> sets the <i>current window</i> to the window
which is about to be closed when the callback is invoked.
<p><b>Changes From GLUT</b></p>
<p>This function is not implemented in GLUT.</p>
