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.
