NAME

       gl_setdisplaystart - set the start of the screen are displayed

SYNOPSIS

       #include <vgagl.h>

       vga gl_setdisplaystart(int x, int y);

DESCRIPTION

       Set the physical display start address to the pixel at (x, y).

       Can  be used for hardware scrolling, or for page flipping (e.g.  setdisplaystart(0, HEIGHT) displays from
       the second page). Make sure the scanline width (BYTEWIDTH) in bytes of the  current  context  corresponds
       with the physical screen.

       Note   also   that   the   display   start   cannot   be   set   to   completely  arbitrary  points,  see
       vga_setdisplaystart(3).
