The Pie function draws a pie-shaped wedge bounded by the intersection of an ellipse and two radials. The pie is outlined by using the current pen and filled by using the current brush.

If the function succeeds, the return value is nonzero.
If the function fails, the return value is zero. To get extended error information, call GetLastError.
The curve of the pie is defined by an ellipse that fits the specified bounding rectangle. The curve begins at the point where the ellipse intersects the first radial and extends counterclockwise to the point where the ellipse intersects the second radial. (A radial is a line drawn from the center of the ellipse to the specified endpoint on the ellipse.)
The current position is neither used nor updated by the Pie function.
Windows 95: The sum of the coordinates of the bounding rectangle cannot exceed 32,767. The sum of nLeftRect and nRightRect or nTopRect and nBottomRect parameters cannot exceed 32,767.
