glutGameModeGet - retrieves GLUT device information repre-
       sented by integers.

SYNTAX

       int glutGameModeGet(GLenum info);

ARGUMENTS

       info      Name of game mode information to retrieve.

       GLUT_GAME_MODE_ACTIVE
               Non-zero if GLUT's game mode is  active;  zero  if
               not  active.   Game  mode is not active initially.
               Game mode becomes active when glutEnterGameMode is
               called.   Game  mode  becomes  inactive when glut-
               LeaveGameMode is called.

       GLUT_GAME_MODE_POSSIBLE
               Non-zero if the game mode string last specified to
               glutGameModeString is a possible game mode config-
               uration; zero otherwise.   Being  "possible"  does
               not  guarantee  that  if game mode is entered with
               glutEnterGameMode that the display  settings  will
               actually  changed.  GLUT_GAME_MODE_DISPLAY_CHANGED
               should be called once  game  mode  is  entered  to
               determine if the display mode is actually changed.

       GLUT_GAME_MODE_WIDTH
               Width in pixels of the screen when  game  mode  is
               activated.

       GLUT_GAME_MODE_HEIGHT
               Height  in  pixels of the screen when game mode is
               activated.

       GLUT_GAME_MODE_PIXEL_DEPTH
               Pixel depth  of  the  screen  when  game  mode  is
               activiated.

       GLUT_GAME_MODE_REFRESH_RATE
               Screen  refresh  rate  in cyles per second (hertz)
               when game mode is activated.  Zero is returned  if
               the  refresh rate is unknown or cannot be queried.

       GLUT_GAME_MODE_DISPLAY_CHANGED
               Non-zero if entering game  mode  actually  changed
               the  display settings.  If the game mode string is
               not possible or the  display  mode  could  not  be
               changed for any other reason, zero is returned.

DESCRIPTION
