Erases the specified rectangular area of the specified window by changing the area to the default background color.
Syntax
void _WClearRect(WHANDLE wh, Rect r)
WHANDLE wh; /* Window handle. */
Rect r; /* Rectangle to clear. */
Remarks
The output position is unchanged.
The area of the rectangle extends from the top left coordinate to, but not including, the bottom right coordinate. This means that you should declare the bottom and right coordinates to be one more than the intended size of the rectangle.
