4.2.6 LineDrawV

void LineDrawV (void *pvDisplayData, long lX1, long 1X2
        long lY, unsigned long ulDispColor);

This function draws vertical lines using the supplied, display-dependent color. As for LineDrawH, the line drawn includes both the first and last pixels specified by parameters lY1 and lY2 meaning that the number of pixels written is ((lY2 – lY1) + 1). The graphics library ensures that lY2 is always greater than lY1 so no parameter sorting is required in the display driver.
