Returns references to some of the input segments.
[Visual Basic .NET] Public Sub QuerySegments ( _ ByVal pSegmentCollection As ISegmentCollection, _ ByVal Index As Integer, _ ByRef segments As ISegment[] _ )
[C#] public void QuerySegments ( ISegmentCollection pSegmentCollection, int Index, ref ISegment[] segments );
[C++]
HRESULT QuerySegments(
ISegmentCollection* pSegmentCollection,
long Index,
Array* segments
);
[C++]
Parameters pSegmentCollection [in]
pSegmentCollection is a parameter of type ISegmentCollection Index Index is a parameter of type long segments [in, out] segments is a parameter of type Array
All development languages compatible version of ISegmentCollection::QuerySegments .
