Sets send buffer size.
You may not need to change this ever.
If you send more data, the function may wait till enough data is sent, so it fits in the buffer. Or OS may automatically resize the buffer.


Test send buffer size:

Set Variable [ $sock ; Value: MBS("Socket.NewTCPSocket") ]
Set Variable [ $defaultValue ; Value: MBS("Socket.GetSendBufferSize"; $sock) ]
Set Variable [ $v ; Value: MBS("Socket.SetSendBufferSize"; $sock; 1024 * 256) ]
Set Variable [ $newValue ; Value: MBS("Socket.GetSendBufferSize"; $sock) ]
Show Custom Dialog [ "Default: " & $defaultValue & ¶ & "Set to: " & $newValue ]
Set Variable [ $r ; Value: MBS("Socket.Close"; $sock) ]
