Double Buffer

[SystemHalted]

I have two questions.
1.How do I plot a pixle to a doublr buffer?
2.How do I display the buffer on my screen?
Thanks.

Just like you would when plotting a regular pixel, but instead of writting to memory at 0xA0000, you write to memory your OS has allocated for you.

You display the buffer simply by copying it to 0xA0000.

I wrote a chapter on graphics programming in DJGPP that covers double buffering (or virtual screens, as I call them) which can be found on my web site at http://www.neuraldk.org... might be of some help.

Cheers,
