int nYStart, // y-coordinate, where fill begins
COLORREF crFill // fill color
);
Parameters
hdc
Handle to a device context.
nXStart
Specifies the logical x-coordinate of the point where filling is to begin.
nYStart
Specifies the logical y-coordinate of the point where filling is to begin.
crFill
Specifies the color of the boundary or of the area to be filled.
