I was going to write an article on wikipedia about bitmaps. But came across this article on Bit Arrays.. ala Bitmaps after a little searching beyond raster graphics. Gotta love that wikipedia.
It's well worth the time learning how it all works and I've created the toggle macro for you:
#define bitmap_toggle(bitmap, i) bitmap[i/8]~=(1<<(i%8))
