void initVideo(int mode)

int getVmode(void)

Return the current active video mode.


int Hres(void)

int Vres(void)

Return the video screen horizontal and vertical resolution in number of pixels, or -1 in case the screen is does not support graphics.


void clearScreen(int colour)

Fill the entire screen with a given colour.


int getPixel(int x, int y)

void setPixel(int x, int y, int c)

Read and return the colour of, or set a single pixel on the screen at coordinates (x,y) in colour (c).
