               gin) of the current window.

               color index.

       GLUT_WINDOW_ACCUM_BLUE_SIZE
               Number of bits of blue stored in the current layer
               of  current  window's accumulation buffer. Zero if
               the current layer of the current window  is  color
               index.

       GLUT_WINDOW_ACCUM_ALPHA_SIZE

               color index.

       GLUT_WINDOW_DOUBLEBUFFER

               height is unknown or not available.

       GLUT_SCREEN_WIDTH_MM
               Width of the screen in millimeters. Zero indicates
               the width is unknown or not available.

       GLUT_SCREEN_HEIGHT_MM
               Height  of  the  screen in millimeters. Zero indi-
               cates the height is unknown or not available.

       GLUT_MENU_NUM_ITEMS
               Number of menu items in the current menu.

       GLUT_DISPLAY_MODE_POSSIBLE

               not.

       GLUT_INIT_DISPLAY_MODE
               The initial display mode bit mask.

       GLUT_INIT_WINDOW_X
               The X value of the initial window position.

       GLUT_INIT_WINDOW_Y
               The Y value of the initial window position.

       GLUT_INIT_WINDOW_WIDTH
               The width value of the initial window size.

       GLUT_INIT_WINDOW_HEIGHT
               The height value of the initial window size.

       GLUT_ELAPSED_TIME
               Number  of  milliseconds since glutInit called (or
               first call to glutGet(GLUT_ELAPSED_TIME)).

               The window system dependent format ID for the cur-
               rent  layer  of  the  current window.  On X11 GLUT
               implementations, this is  the  X  visual  ID.   On
               Win32  GLUT  implementations,  this  is  the Win32
               Pixel Format Descriptor  number.   This  value  is
               returned  for debugging, benchmarking, and testing
               ease.

DESCRIPTION

       glutGet retrieves simple GLUT state represented  by  inte-
       gers. The state parameter determines what type of state to
       return.  Where appropriate,  window  capability  state  is
       returned  for the layer in use. GLUT state names beginning
       with GLUT_WINDOW_ return state  for  the  current  window.
       GLUT  state  names  beginning with GLUT_MENU_ return state
       for the current menu. Other GLUT state names return global
       state.  Requesting  state  for  an invalid GLUT state name
       returns negative one.
