Programmatically access link information in C++ plugin

Hello,

I would like to access the links in the link list in my C++ plugin.

I need the path to the linked file and the page number.

I came up with some code that works, but it seems a bit cumbersome to me and i am not sure if this is the right approach.

static void logAllLinks(const IDocument* const doc)
{
	IDataBase* db = ::GetDataBase(doc);

	LinkQuery query;
	InterfacePtr<ILinkManager> linkMgr(db, db->GetRootUID(), UseDefaultIID());

	InterfacePtr<IPageList> pages(doc, UseDefaultIID());

	UIDList uids(db);

	const int32 cnt = linkMgr->QueryLinks(query, kIDLinkClientID, uids);
	for (int32 i = 0; i < cnt; ++i)
	{
		UIDRef linkRef(db, uids[i]);

		InterfacePtr<ILink> link(linkRef, UseDefaultIID());

		UID resUID = link->GetResource();
		InterfacePtr<ILinkResource> linkResource(db, resUID, UseDefaultIID());


		// get link name (path)
		PMString linkName = linkResource->GetLongName(false);

		// get modification date
		IDTime modtime    = linkResource->GetModTime();
		WideString timeString;
		bool success = modtime.DateToString(timeString, false);

		// get frame
		UID frameUID    = link->GetObject();
		UIDRef frameRef = UIDRef(db, frameUID);


		InterfacePtr<IHierarchy> hierarchy(frameRef, UseDefaultIID());

		// get parent
		UID parentUID         = hierarchy->GetParentUID();
		UIDRef parentFrameRef = UIDRef(db, parentUID);

		// get page
		UID pageUID = Utils<ILayoutUtils>()->GetOwnerPageUID(hierarchy, kTrue);

		int32 pageNum = pages->GetPageIndex(pageUID);
		pageNum += 1; // 0 - based

		AppGlobals::Instance().getLogger()->log("logAllLinks: Found link: [frame: %d] [parent frame: %d] [name: %s] [page: %d] [modified: %s]", Logger::E_LOG_LEVEL::ELL_DEBUG,
			frameRef.GetUID().Get(), parentFrameRef.GetUID().Get(), Helper::stringWithPMString(linkName).c_str(), pageNum, Helper::stringWithPMString(timeString).c_str());
	}
}

Is there an easier way to do this and are there any pitfalls I need to be aware of?

Thanks
