Win32中的RedrawWindow和UpdateWindow有什么区别？
Since they seem to have the same purpose to refresh a window, what are the differences?
既然它们似乎具有相同的刷新窗口的目的，那么它们之间的区别是什么？

RedrawWindowis typically used to force a redraw of the entire window (or some specified region within) right now.
RedrawWindow通常用于立即强制重绘整个窗口（或其中的某些指定区域）。
UpdateWindowwill force a redraw of only the update region of the window, i.e. that part of the window that has been invalidated (e.g. by calling InvalidateRect) since the last paint cycle.
UpdateWindow将仅强制重绘窗口的更新区域，即InvalidateRect自上次绘制周期以来已失效（例如通过调用）的窗口部分。
