パラメーター

名前	型	方向	説明
ExternalHandle	LDAP*	inout	対象のLDAPセッションハンドル。ページ検索を実行中の接続を指す。
SearchHandle	PLDAPSearch	in	ldap_search_init_pageで取得した検索ブロックハンドル。ページ状態を保持する。
timeout	LDAP_TIMEVAL*	inout	応答待ちのタイムアウト値(timeval構造体)。NULLで無制限待機。
PageSize	DWORD	in	今回取得するページのエントリ数。1ページ分の件数を指定する。
TotalCount	DWORD*	inout	サーバ見積もりの総エントリ数を受け取る出力先。
Results	LDAPMessage**	inout	取得したページの結果メッセージを受け取る出力先。ldap_msgfreeで解放する。
