パラメーター

名前	型	方向	説明
hRasServer	INT_PTR	in	MprAdminServerConnectで取得したRASサーバー接続ハンドル(INT_PTR)。
pObjectHeader	MPRAPI_OBJECT_HEADER*	in	バージョンとサイズを示すMPRAPI_OBJECT_HEADER構造体へのポインタ。
dwPreferedMaxLen	DWORD	in	返却データの推奨最大バイト数。-1で制限なしとなる。
lpdwEntriesRead	DWORD*	out	実際に読み取られたエントリ数を受け取る変数へのポインタ。
lpdwTotalEntries	DWORD*	out	列挙可能な総エントリ数を受け取る変数へのポインタ。
ppRasConn	RAS_CONNECTION_EX**	out	確保されたRAS_CONNECTION_EX構造体配列へのポインタを受け取る変数。MprAdminBufferFreeで解放する。
lpdwResumeHandle	DWORD*	in	列挙再開位置を保持する入出力変数へのポインタ。初回は0を指す。NULL可。
