Indy9で書かれたプログラム

```

    void __fastcall TfrmMain::ServerConnect(TIdPeerThread *AThread)
    {
    ----------(中略)---------------------------------------
        TIdTCPServerConnection * con = AThread->Connection;
    ----------(中略)---------------------------------------
           int iExpectedLen = 0, iStackBufSize=0;
    ----------(中略)---------------------------------------
           iStackBufSize = con->ReadFromStack(true,5000,true);
    ----------(中略)---------------------------------------
    }
    
```

このプログラムをIndy10のプログラムに移行したいのですが、ReadFromStackというのをIndy10の取説でキーワード検索しても出てこないのですが、同等の機能というものはありますでしょうか？

TIdTCPConnection.ReadFromStackと同等の機能はIndy10にはありますか？

それの類推でこれあたりが該当しそうです。

実際に関係するのか、どのように使えば良いか等は調べてみてください。
