Chord function Null safety
The Chord function draws a chord (a region bounded by the intersection of an ellipse and a line segment, called a secant). The chord is outlined by using the current pen and filled by using the current brush.
BOOL Chord( HDC hdc, int x1, int y1, int x2, int y2, int x3, int y3, int x4, int y4 );
int Chord(int hdc, int x1, int y1, int x2, int y2, int x3, int y3, int x4, int y4) => _Chord(hdc, x1, y1, x2, y2, x3, y3, x4, y4);
