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 glutLeaveGameMode is called.
GLUT_GAME_MODE_POSSIBLE
  Non-zero if the game mode string last specified to glutGameModeString is a possible game mode configuration; 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

glutGameModeGet retrieves GLUT game mode information represented by integers. The info parameter determines what type of game mode information to return. Requesting game mode information for an invalid GLUT game mode information name returns negative one.
