Polygon function Null safety gdi32

int Polygon(
  1. int hdc,
  2. Pointer<POINT> apt,
  3. int cpt
)

The Polygon function draws a polygon consisting of two or more vertices connected by straight lines. The polygon is outlined by using the current pen and filled by using the current brush and polygon fill mode.

BOOL Polygon(
  HDC         hdc,
  const POINT *apt,
  int         cpt
);

Implementation

int Polygon(int hdc, Pointer<POINT> apt, int cpt) {
  final _Polygon = _gdi32.lookupFunction<
      Int32 Function(IntPtr hdc, Pointer<POINT> apt, Int32 cpt),
      int Function(int hdc, Pointer<POINT> apt, int cpt)>('Polygon');
  return _Polygon(hdc, apt, cpt);
