I need some help from some of you more experienced Mac programmers.
Although I am well versed in C, I am just starting to program in the
Macintosh environment.

I have a window which I use QuickDraw routines to draw characters.  (Not
a text edit window, that is)  I am have difficulties responding to an
update event.  I have IM volumes and several different books, but none of
them sufficiently covers the use of an offscreen buffer to store window
info for updating.  

How does one set up an offscreen buffer so that CopyBits may be used to 
refresh the window when responding to an update event?
