pwzLocation	LPCWSTR	in	ターゲット内の位置を示す文字列。NULL可。
pwzFriendlyName	LPCWSTR	in	表示用のわかりやすい名前。NULL可。
pihlsite	IHlinkSite*	in	ハイパーリンクのサイトインターフェイス。NULL可。
dwSiteData	DWORD	in	サイトに関連付けるユーザー定義データ値。
piunkOuter	IUnknown*	in	アグリゲーション時の外側IUnknown。通常はNULL。
riid	GUID*	in	要求するインターフェイスの識別子GUIDへのポインタ。通常はIID_IHlink。
ppvObj	void**	out	生成したハイパーリンクオブジェクトを受け取る出力先。
