Bitmaps in QuickDraw

I am trying to do some animation using bitmaps in QuickDraw.  I found the
function make-bitmap which returns a new bitmap.  However, I can't find
the functions of setting pixels in the rectangular array.  Also we should
have some functions, e.g., sleep or waiting, and display the bitmap on the
window, for drawing the sequence of the pictures.  However, I can't find
those.  Does anyone know those?  Thanks much.
