# _WinAPI_Arc

Draws an elliptical arc

#include <WinAPIGdi.au3>
_WinAPI_Arc ( $hDC, $tRECT, $iXStartArc, $iYStartArc, $iXEndArc, $iYEndArc )

## Parameters

$hDC | Handle to the device context.
$tRECT | $tagRECT structure that contains the logical coordinates of the bounding rectangle.
$iXStartArc | The x-coordinate, in logical units, of the ending point of the radial line defining the starting point of the arc.
$iYStartArc | The y-coordinate, in logical units, of the ending point of the radial line defining the starting point of the arc.
$iXEndArc | The x-coordinate, in logical units, of the ending point of the radial line defining the ending point of the arc.
$iYEndArc | The y-coordinate, in logical units, of the ending point of the radial line defining the ending point of the arc.

## Return Value

Success: | True
Failure: | False

## Remarks

The arc is drawn using the current pen; it is not filled. The current position is neither used nor updated by _WinAPI_Arc() function.
Use the _WinAPI_GetArcDirection() and _WinAPI_SetArcDirection() functions to get and set the current drawing direction for a device context.
The default drawing direction is counterclockwise.
