_GetArcInfo Function
  Summary Details Example                                   Back
 
  Arguments
 
    startpoint    Specifies point where arc begins
 
    endpoint      Specifies point where arc ends
 
    fillpoint     Specifies point where pie fill would begin
 
  Returns
 
    Boolean       False is returned if neither _Arc or _Pie has been
                  successfully called since the last time the screen
                  was cleared or a new graphics mode or viewport was
                  selected; otherwise, true
 
  Description
 
    If successful, the _GetArcInfo function updates the startpoint and
    endpoint _XYCoord records to contain the endpoints (in viewport
    coordinates) of the arc drawn by the most recent call to _Arc (or
    _Pie). In addition, fillpoint specifies a point from which a pie
    can be filled. This is useful for filling a pie in a different
    color than the border color. After a call to _GetArcInfo, you
    would change colors using the _SetColor procedure, and use the
    coordinates in fillpoint and the old color as arguments for the
    _FloodFill procedure.
 
  _GrStatus Returns
