how to limit the lnet console ltcp lclient/lserver example to one
connection

Hello all,

I'm trying to limit the connections of the lnet ltcp console
client/server example to just one connection.

Also i'd like to send the server reply directly to the 1 client
without iterating, unlike like below.

-- snippet lserver.pp
    FCon.IterReset; // now it points to server socket
    while FCon.IterNext do begin // while we have clients to echo to
      n := FCon.SendMessage(s, FCon.Iterator);
      if n < Length(s) then // try to send to each of them
        Writeln('Unsuccessful send, wanted: ', Length(s), ' got: ',
n); // if send fails write error
    end;
--

It's probably not to complicated (i imagine there is some property for
this). But so far i can't find much reference documentation other than
the xml file in the package (which i have no idea how to view properly
yet), and the object definitions in the lnet.pp file.

Note that i use a command line fpc and haven't been able to import the
package in my lazarus win64 (v1.2.6). So maybe when imported correctly
reference xml data is available. Not really sure on this.

Any help with this is much appreciated!

Regards,
Rick

Perhaps FCon.SendMessage(s, aSocket);?

I guess this could work if one global stores the asocket at .onAC and
re uses it at .onRe.

But the basic thing i'm looking for is something like
"FCon.MaxConnections:=1;" (in .create), so there will be just one
connection .. (btw: this is just an example, i know it does not exist)
