glutForceJoystickFunc(3GLUT)         GLUT         glutForceJoystickFunc(3GLUT)


NAME

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


SYNTAX


       void glutForceJoystickFunc(void);


DESCRIPTION

       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 glutJoystickFunc's pollInterval
       (specified in milliseconds) or in response to calling
       glutForceJoystickFunc.  If the pollInterval is non-positive, no
       joystick polling is performed 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 callback is called from
       glutJoystickFunc.  That is, when glutJoystickFunc returns, the callback
       will have already happened.

GLUT IMPLEMENTATION NOTES FOR X11
       The GLUT 3.7 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.

GLUT IMPLEMENTATION NOTES FOR WIN32
       The GLUT 3.7 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 GLUT 3.7 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.
