The PolylineTo function draws one or more straight lines.

BOOL PolylineTo(

    HDC hdc,

// handle of device context

    CONST POINT *lppt,

// address of array of points

    DWORD cCount 

// number of points in array



Identifies the device context.
Points to an array of POINT structures that contains the vertices of the line.
Specifies the number of points in the array.

Return Values

If the function succeeds, the return value is nonzero.

If the function fails, the return value is zero. To get extended error information, call GetLastError.


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.
