gl_setcontextvga (3)

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 .
