int IsTextDataAtLocation(Microsoft::VisualStudio::TextManager::Interop::IVsTextLines const & pBuffer, int iLine, int iCol, [Runtime::InteropServices::Out] int & pfIsTextDataValidAtLoc);
public int IsTextDataAtLocation (Microsoft.VisualStudio.TextManager.Interop.IVsTextLines pBuffer, int iLine, int iCol, out int pfIsTextDataValidAtLoc);
