Hi,

I am using the ClienSocket VCL component of Borland C++6.0.
How do I access and set the UseNagle option to [false] for the associated socket ? (required for me to avoid concatenation of packets, 
On Visual C++ 2005, there is a function called setsockopt() which does this stuff. 
On Borland C++ 6.0, there is a Nagle property in TIdTCPClient component, but ClientSocket comes from a TClientSocketThread component. 
Any idea ?

Google is your friend. Searched for NAGLE BORLAND

You have to use the setsockopt() function from the WinSock API directly.
For example:

    void __fastcall TForm1::ClientSocket1Connect(TObject *Sender,
TCustomWinSocket *Socket)
    {
        BOOL disabled = TRUE;
        setsockopt((SOCKET)Socket->SocketHandle, IPPROTO_TCP, TCP_NODELAY,
(char*)&disabled, sizeof(BOOL));
    }

this stuff.

That is an API function.  It is available to Borland compilers as well.
