glutGameModeGet(3GLUT) GLUT glutGameModeGet(3GLUT)
NAME
glutGameModeGet - retrieves GLUT device information represented 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 glutLeaveGameMode is called.
GLUT_GAME_MODE_POSSIBLE
Non-zero if the game mode string last specified to glutGameMo-
deString 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 dis-
play 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 informa-
tion to return. Requesting game mode information for an invalid GLUT
game mode information name returns negative one.
