パラメーター

名前	型	方向	説明
servername	LPCWSTR	in	操作対象サーバー名。NULLでローカルコンピュータを指す。
level	DWORD	in	返す情報レベル(REPL_IDIR_INFO_0/1)。
bufptr	BYTE**	inout	確保された結果バッファへのポインタを受け取る出力引数。NetApiBufferFreeで解放する。
prefmaxlen	DWORD	in	返すデータの推奨最大バイト数。MAX_PREFERRED_LENGTHで上限なし。
entriesread	DWORD*	inout	実際に読み取られたエントリ数を受け取る出力ポインタ。
totalentries	DWORD*	inout	利用可能な総エントリ数を受け取る出力ポインタ。
resumehandle	DWORD*	inout	列挙継続用のハンドルへのポインタ。初回は0を指定する。
