recive data in loop

[CreaM]

Hi, how can i receive data in same loop, and in case no data comes in three secs (for example) the loop continues

- i could sand data at,,every start of loop,, just sometimes ,,fill them,, but isnt another easier way?

As a bonus, the timeout capability of Selector::wait allows to implement a receive-with-timeout function, which is not directly available in the socket classes, very easily:

sf::Socket::Status receiveWithTimeout(sf::TcpSocket& socket, sf::Packet& packet, sf::Time timeout)
{
    sf::SocketSelector selector;
    selector.add(socket);
    if (selector.wait(timeout))
        return socket.receive(packet);
    else
        return sf::Socket::NotReady;
}
