UNTITLED
							       LOCAL								  UNTITLED

NAME

     glutGetModifiers -- Returns the status of Alt, Shift, and Ctrl keys.

LIBRARY

     OpenGLUT - inputstate

SYNOPSIS

     #include <openglut.h>

     int
     glutGetModifiers(void);

DESCRIPTION

     According to which, if any, modifier keys are held, the return value is the logical  OR  combination of any of the following symbolic bit-
     masks:

      -  GLUT_ACTIVE_SHIFT
      -  GLUT_ACTIVE_CTRL
      -  GLUT_ACTIVE_ALT

     E.g., if the shift key is held, and no other modifier keys are held, this function will return  GLUT_ACTIVE_SHIFT.

BUGS

     Complains if not invoked by a client callback.

     Does not differentiate between the left and right forms of the modifiers.

NAME

     glutDeviceGet -- Allows you to get some device state/option variables.

LIBRARY

     OpenGLUT - inputstate

SYNOPSIS

     #include <openglut.h>

     int
     glutDeviceGet(GLenum eWhat);

PARAMETERS

      eWhat	Enumerated parameter ID.

DESCRIPTION

     Retrieves some system-specific information about attached devices.  Supported device queries are:

      -  GLUT_HAS_JOYSTICK
     Return non-zero if there is a joystick.

      -  GLUT_HAS_KEYBOARD
     Return non-zero if there is a keyboard.

      -  GLUT_HAS_MOUSE
     Return non-zero if there is a mouse.

      -  GLUT_HAS_SPACEBALL
     Return non-zero if there is a spaceball.

      -  GLUT_JOYSTICK_AXES
     Return the number of axes for the joystick.

      -  GLUT_JOYSTICK_POLL_RATE
     Return the rate (in GLUT timer ticks?) at which the joystick is polled.

      -  GLUT_NUM_MOUSE_BUTTONS
     Return the number of buttons that the user's mouse has.

      -  GLUT_OWNS_JOYSTICK
     Return non-zero if OpenGLUT believes that it has successfully acquired access to the joystick.

      -  GLUT_DEVICE_IGNORE_KEY_REPEAT
     Return non-zero if the  current window   is set to disable key repeating.

      -  GLUT_DEVICE_KEY_REPEAT
     Described as returning the key repeat rate in one place, but actually returns a key repeat mode.

      -  GLUT_HAS_DIAL_AND_BUTTON_BOX
     Return non-zero if a dials-and-buttons box is present.

      -  GLUT_HAS_TABLET
     Return non-zero if a tablet is present.

      -  GLUT_NUM_BUTTON_BOX_BUTTONS
     Return the number of buttons on a dials-and-buttons box, if any.

      -  GLUT_NUM_DIALS
     Return the number of dials on a dials-and-buttons box, if any.

      -  GLUT_NUM_SPACEBALL_BUTTONS
     Return the number of buttons on a spaceball, if any.

      -  GLUT_NUM_TABLET_BUTTONS
     Return the number of buttons on a tablet, if any.

TODO

     Only supports querying for one joystick.

     Consider moving to a table-based approach rather than a switch(), letting us move to modular functions.

BUGS

     Keyboards are optional, but OpenGLUT doesn't detect their absence.

     Mice are optional, but OpenGLUT is only able to check for them under WIN32.

     Mice can have a varying number of buttons, but OpenGLUT assumes exactly 3 on UNIX_X11.

     Not all joystick queries are implemented yet.

      GLUT_DEVICE_KEY_REPEAT  returns the key repeat mode, but the comment says it returns the	rate  .

     Some things, like joystick poll rates, seem to have insufficient context.	Which joystick?  Which window? Maybe we assume the  current window
       and the current joystick (or the first one)?

      GLUT_DEVICE_KEY_REPEAT  should probably return  ogState.KeyRepeat.
