glutGameModeGet - retrieves GLUT device information represented by
integers.
#include <GLUT/glut.h>
int glutGameModeGet(GLenum info);
- 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.
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.
