NAME¶
gl_setcontextvgavirtual - set the context to a virtual mode
SYNOPSIS¶
#include <vgagl.h>
int gl_setcontextvgavirtual(int mode);
DESCRIPTION¶
Allocate a virtual screen in system memory identical to the graphics mode (as
defined in
vga_setmode(3)), and make that the current graphics context.
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.
