Jeez Eric,
Thank you for your mail:-
BB> Pixels are not standard C.
EK> Pixels are standard to any language if you do it
EK> right.
Be still, my heart. :-) I was not looking for an argument, Eric, or
guidance - just talking about the ANSI standard for C - the subject of this
echo.
> You can access the video memory directly
[much cut]
See my message to Nick Tesla, Eric. All the above assumes PC
architecture, and a memory mapped video monitor. It also assumes an xxx86
processor, an Ms- Dos interrupt structure and software interrupts. There is
no virtue in substituting one set of non-standard functions for another.
All the low-level stuff you suggested is non-standard and PC specific. On a
PC, you might be better to use an otherwise standard compiler that knows
about pixels in the first place. :-) It would make more sense to use
curses, but that's another story. :-)
It would be plain silly to expect your code to work on a 68000 using a
Wyse-50 VDU with Pick as the operating system, or a PDP-11 running BSD 4.2
with 256 ASR-33s. :-) ANSI standard C has to. That's why it doesn't have
pixels. :-)
> Hope that helps,
I hope so, too. Better ask David, though. :-)
Bill.
