Blocking/unblocking sockets

[Daffern]

I have been trying to set up a tcp and udp network, and i want to use nonblocking sockets. However i noticed that when i'm using nonblocking sockets the return code for udpSocket.bind() and tcpSocket.connect() doesnt return sf::Socket::Done even if the operation was successful. My workaround was doing this:

tcpSocket.setBlocking(true);
if (tcpSocket.connect(ip,port, sf::seconds(3) ) != sf::TcpSocket::Done){
   std::cout<<"Failed to connect TCP"<<std::endl;
   tcpSocket.setBlocking(false);
}

Is this intended and is this a good or a bad way to do it?

EDIT: tcpSocket.receive() also returns sf::Socket::Done when it doesn't receive anything in nonblocking mode

Yes, this is a good strategy. Note that non-blocking connect will be fixed in SFML 2.1.

tcpSocket.receive() also returns sf::Socket::Done when it doesn't receive anything in nonblocking mode

This one is strange. Can you provide a complete and minimal code that reproduces the problem?

Thanks for the reply!

I just tested it and found out it was my bad, the tcpSocket does return the right status code. I forgot to set every new tcp socket to nonblocking mode after it had connected so that the program froze when it received something.

Also i want to thank the people working with sfml, i find it extremely fun to code with sfml and c++
