Hello

I'm trying to connect to server and send data, with such simple client:

#!/usr/bin/rdmd

import std.stdio;
import std.socket;
import std.socketstream;
import std.process;
import std.conv;
import core.time;

void main()
{
        char[1024] buffer = 0;

        Socket client = new TcpSocket();
auto addrServer = new InternetAddress("localhost", 8080);
        client.connect(addrServer);

        while(1)
        {

                client.send(readln());
                client.receive(buffer);
                writeln(buffer);
                buffer = 0;
         }
}

It is working but only one time, when I'm trying to send again (second loop of while) it's stooping on readln() but not sending input data.

What am i missing here?

Thanks in advance for any help.

Where is the other side of this client? There must be a TCP Server to listen connections, and create a second TCPSocket for communication. There is only one TCPSocket in your code. A lot of things are missing there. I would suggest you to check "C TCPSocket example" in your favourite search engine.
