rgrc

Specifies an array of rectangles. The first contains the new coordinates of a window that has been moved or resized. The second contains the coordinates of the window before it was moved or resized. The third contains the coordinates of the window s client area before the window was moved or resized. If the window is a child window, the coordinates are relative to the client area of the parent window. If the window is a top-level window, the coordinates are relative to the screen origin.

lppos

Points to a WINDOWPOS structure that contains the size and position values specified in the operation that moved or resized the window.
