			<tt>glutForceJoystickFunc</tt> forces the current window's joystick callback to be called, reporting the
			latest joystick state.
		</p><p>
			The joystick callback is called either due to polling of the joystick at the uniform timer interval set by <a href="glutJoystickFunc.3GLUT.xml"><tt>glutJoystickFunc</tt></a>'s <i><tt>pollInterval</tt></i> (specified in milliseconds) or in
			response to calling <tt>glutForceJoystickFunc</tt>. If the <i><tt>pollInterval</tt></i> is
			non-positive, no joystick polling is performed and the GLUT application must frequently (usually from an idle callback)
			call <tt>glutForceJoystickFunc</tt>.
		</p><p>
			The joystick callback will be called once (if one exists) for each time <tt>glutForceJoystickFunc</tt> is
			called. The callback is called from <a href="glutJoystickFunc.3GLUT.xml"><tt>glutJoystickFunc</tt></a>. That is, when <a href="glutJoystickFunc.3GLUT.xml"><tt>glutJoystickFunc</tt></a> returns, the callback will have already happened.

			The current implementation of GLUT for X11 supports the joystick API, but not actual joystick input. A future
			implementation of GLUT for X11 may add joystick support.
		</p></div><div class="refsect1" lang="en"><a name="glutForceJoystickFunc.3GLUT-glut_implementation_notes_for_win32"/><h2>Glut Implementation Notes For Win32</h2><p>
			The current implementation of GLUT for Win32 supports the joystick API and joystick input, but does so through the
			dated joySetCapture and joyGetPosEx Win32 Multimedia API. The current GLUT joystick support for Win32 has all the
			limitations of the Win32 Multimedia API joystick support. A future implementation of GLUT for Win32 may use
			DirectInput.
