WINDOWS

Summary:

The BeginPaint() function returns a far pointer to a PAINTSTRUCT data

structure through its second parameter. The rcPaint field of this

structure specifies the update rectangle in client-area coordinates

(relative to the upper-left corner of the window client area).

This update rectangle also serves as the clipping area for painting in

the window, unless the invalid area of the window is expanded using

the InvalidateRect() function.
