GLUTDEVICEGET(3)                 Local Manual                 GLUTDEVICEGET(3)

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.  Sup-
     ported 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.
