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 glutForceJoy-
stickFunc. 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 glutJoy-
stickFunc. 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 sup-
port. A future implementation of GLUT for Win32 may use DirectInput.
