In order to reduce the communications traffic between a graphics program and a graphics device, GINO and some device drivers store information in a buffer, ready to send it to the device in bursts. This may have the effect that the display is not up-to-date with the sequence of GINO calls within the program.
The routine gFlushGraphics() ensures all graphics information held in all internal buffers within GINO and the current graphics device is sent to the display.
