NAME

       gl_setcontextvga - set the context to the physical screen

SYNOPSIS

       #include <vgagl.h>

       int gl_setcontextvga(int mode);

DESCRIPTION

       Set  the  graphics  context  to  the  physical screen of a vga mode (as
       defined in vga_setmode(3)).  The mode must be set  with  vga_setmode(3)
       prior  to using any of the drawing functions.  vgagl does not take care
       of that.

       The function returns 0 for success and non-zero  if  the  mode  is  not
       supported by the hardware.

       The only thing you can do with a planar (mode X-like) 256 color mode is
       aligned gl_putbox, and use it as a target for gl_copyscreen.

       In all of the svga modes this program makes a description  of  the  vga
       mode  available  to  the  vgagl functions.  The 256 color svgamodes are
       handled properly by this program.
