The Polyline function draws a series of line segments by connecting the points in the specified array.

Syntax

BOOL Polyline(
  [in] HDC         hdc,
  [in] const POINT *apt,
  [in] int         cpt
);

Parameters

[in] hdc

A handle to a device context.

[in] apt

A pointer to an array of POINT structures, in logical units.

[in] cpt

The number of points in the array. This number must be greater than or equal to two.

Return value

If the function succeeds, the return value is nonzero.

The lines are drawn from the first point through subsequent points by using the current pen. Unlike the LineTo or PolylineTo functions, the Polyline function neither uses nor updates the current position.
