clipping path

I'm trying to draw a structure in Windows GDI within a certain clip path to verify the functionalities of my printer driver. However, I would like to confirm about whether my client application test code would be functional since I have been encounterring some problems with the clip path that I would like to isolate between the client application and the driver.

This is my clip region drawing function.

Code:

---

void RectDraw(HDC *hdc)
{
        BOOL success;
        int nX = 150;
        int nY = 150;
        DWORD dwRadius = 100;
        float xStartAngle = 60;
        float xSweepAngle = 60;
        HGDIOBJ hNewObj;
        HBRUSH hBrush;

        POINT points[] = {
                {1700, 1700},
                {2000, 2000},
                {2562, 1503}
        };

        // set up the brush
        hBrush = CreateSolidBrush(RGB(44, 25, 64));

        // Begin Path
        success = BeginPath(*hdc);

        // Create a Path
        success = Rectangle(*hdc, 150, 150, 200, 200);

        success = EndPath(*hdc);
        success = SelectClipPath(*hdc, RGN_AND);
}

The clip region drawing function is called before the pie path filling function, like as shown below:

Code:

---

RectDraw(&hDC);
PieDraw(&hDC);                                // has shown to work

---

The clipping path function is implemented roughly according to the documentation on Windows GDI in MSDN. Any comments would be muchly appreciated.
