PolylineTo function (wingdi.h)

The PolylineTo function draws one or more straight lines.


BOOL PolylineTo(
  [in] HDC         hdc,
  [in] const POINT *apt,
  [in] DWORD       cpt


[in] hdc

A handle to the device context.

[in] apt

A pointer to an array of POINT structures that contains the vertices of the line, in logical units.

[in] cpt

The number of points in the array.

Return value

If the function succeeds, the return value is nonzero.

If the function fails, the return value is zero.


Unlike the Polyline function, the PolylineTo function uses and updates the current position.

A line is drawn from the current position to the first point specified by the lppt parameter by using the current pen. For each additional line, the function draws from the ending point of the previous line to the next point specified by lppt.

PolylineTo moves the current position to the ending point of the last line.

If the line segments drawn by this function form a closed figure, the figure is not filled.
