Hello,

which is the fastest way to access video memory in DJGPP?

I have tried these two ways:

1.
void set_video_mode(int mode)
{
         union REGS regs;
regs.x.ax = mode;
int86(0x10, &regs, &regs);
}

2.
void set_video_mode(int mode)
{
__dpmi_regs regs;
regs.x.ax = mode;
__dpmi_int(0x10, &regs);
}

Which of these two is the fastest way to access video memory, or is there a
faster way? Please e-mail me if you have any idea (or comments!).

thanx, 

// Jakob
