There's plenty of information around on this topic.

As a starting point you can read this Wiki article: http://bb4w.wikispaces.com/Direct+screen+memory+access

You could also look at some of Tony Tooth's programs, in which he does exactly what you describe: http://www.tonytooth.co.uk/

Or you could use David Williams' GFXLIB library: http://www.bb4w-games.com/gfxlib/gfxlib.html
