Public Sub QueryChordLengthTangents ( _
    ByVal pointIndex As Integer, _
    ByVal prevTangent As IPoint, _
    ByRef prevSetByUser As Boolean, _
    ByVal nextTangent As IPoint, _
    ByRef nextSetByUser As Boolean _
)
[C#]
public void QueryChordLengthTangents (
    int pointIndex,
    IPoint prevTangent,
    ref bool prevSetByUser,
    ref IPoint nextTangent,
    ref bool nextSetByUser
);
[C++]
HRESULT QueryChordLengthTangents(
  long pointIndex,
  IPoint* prevTangent,
  Boolean* prevSetByUser,
  IPoint* nextTangent,
  Boolean* nextSetByUser
);
