Hi!

I have a problem with sockets, namely, a non-blocking mode. I must say that until that moment I had never worked with sockets and my
question may seem silly.
In my project, I repeated the tutorial from the Help Topics "Connection-Oriented Socket Tutorial"

Function accept_socket.Accept (data_socket, & ip_addr)
suspends the entire program, so I point out that the socket nonblocking:

        Socket::Init();
	
	if( !ServerSocket(accept_socket, portInfo.portNumber) )
		throw Exc("Couldn't bind socket on the local port.");

	if( accept_socket.IsOpen() )
	{
		dword ip_addr;
		accept_socket.Block(false);
                accept_socket.Peek();
		
		if( !accept_socket.IsError() && accept_socket.Accept(data_socket, &ip_addr) )
		{
			Cout() << "Connection from " << FormatIP(ip_addr) << "\n";
			
			while(data_socket.IsOpen() && !data_socket.IsEof() && !data_socket.IsError())
				Cout() << data_socket.Read();
		}
	}

But the program still awaits all perform the function Accept. What I missed or am doing wrong?

Also I read that non-blocking socket's have callback when connection started(or something like that). Could you give examples code using this opportunity socket?

P.S.
Sorry my english )
