The SetRectEmpty function creates an empty rectangle in which all coordinates are set to zero.
BOOL SetRectEmpty(
[out] LPRECT lprc
);
[out] lprc
Pointer to the RECT structure that contains the coordinates of the rectangle.
If the function succeeds, the return value is nonzero.
If the function fails, the return value is zero.
Because applications can use rectangles for different purposes, the rectangle functions do not use an explicit unit of measure. Instead, all rectangle coordinates and dimensions are given in signed, logical values. The mapping mode and the function in which the rectangle is used determine the units of measure.
For an example, see Using Rectangles.
