glutForceJoystickFunc  -  forces current window's joystick
callback to be called.

glutForceJoystickFunc
	glutForceJoystickFunc() -> None

void glutForceJoystickFunc(void);

glutForceJoystickFunc forces the current window's joystick
callback  to  be  called,  reporting  the  latest joystick
state.

The joystick callback is called either due to  polling  of
the joystick at the uniform timer interval set by glutJoy-
stickFunc's pollInterval (specified in milliseconds) or in
response   to   calling   glutForceJoystickFunc.   If  the
pollInterval is non-positive, no joystick polling is  per-
formed  and  the GLUT application must frequently (usually
from an idle callback) call glutForceJoystickFunc.

The joystick callback will be called once (if one  exists)
for  each time glutForceJoystickFunc is called.  The call-
back is  called  from  glutJoystickFunc.   That  is,  when
glutJoystickFunc  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.

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 Direct-
Input.
