Copies vertices'/points' coordinates to the array of point structures.
[Visual Basic .NET] Public Sub QueryWKSPoints ( _ ByVal pPointCollection As IPointCollection4, _ ByVal Index As Integer, _ ByRef pointStructures As WKSPoint[] _ )
[C#] public void QueryWKSPoints ( IPointCollection4 pPointCollection, int Index, ref WKSPoint[] pointStructures );
[C++]
HRESULT QueryWKSPoints(
IPointCollection4* pPointCollection,
long Index,
SAFEARRAY(WKSPoint)* pointStructures

[C++]
Parameters pPointCollection [in]
pPointCollection is a parameter of type IPointCollection4* Index [in]
Index is a parameter of type long pointStructures [in, out]
pointStructures is a parameter of type SAFEARRAY(WKSPoint)*
