I just started with graphics using DJGPP and heard
that using nearptr-method would be faster than using
farptr.Is this correct?My second question is:

void putpixel(int x,int y,char c)
{
__djgpp_nearptr_enable();
[...]
__djgpp_nearptr_disable();
}

Isnīt this slow because of the frequent memory protection switching?One
could enable nearptr at
the beginning of a program and disable it at the end.
This should make it a lot faster.One could take the advantage of the new
memmodel and so on and
could go on programming like in reall mode.Certainly
itīa bit dangerous, but what can actually happen?
Your computer wonīt be destroyed I think.The point
is that in this way you could save alot of time in programs which do a lot
of graphics, couldnīt you?

Your opinion(please donīt forget my question)
