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