パラメーター

名前	型	方向	説明
ld	LDAP*	inout	検索を実行する対象のLDAPセッションハンドル。
base	LPCWSTR	inoptional	検索の起点となるベースDN(Unicode)。この識別名を基準に探索する。
scope	DWORD	in	検索範囲を示すフラグ。LDAP_SCOPE_BASE/ONELEVEL/SUBTREEのいずれかを指定する。
filter	LPCWSTR	in	検索フィルター文字列(Unicode)。RFC形式の検索条件を指定する。
attrs	WORD**	in	取得する属性名のNULL終端配列。NULLで全属性を返す。
attrsonly	DWORD	in	属性名のみ取得するかのフラグ。非0で値を除き属性名だけを返す。
res	LDAPMessage**	out	検索結果メッセージを受け取るLDAPMessage*へのポインタ。使用後はldap_msgfreeで解放する。
