Question: Can sf::TcpListener pick a random available port?

[Unarelith]

Subject

sf::UdpSocket is capable of selecting a random available port as described in the documentation, using sf::UdpSocket::bind(sf::Socket::AnyPort):

You can use the special value Socket::AnyPort to tell the system to automatically pick an available port, and then call getLocalPort to retrieve the chosen port.

But there is nothing about sf::TcpListener::listen(sf::Socket::AnyPort).

I tried on my ArchLinux. It works as expected, and I can use sf::TcpListener::getLocalPort to know which port it decided to pick.

Is the documentation missing, or is it unsupported/not portable/something else?

Your environment

• ArchLinux
• SFML 2.5

I'd say the documentation is missing. Internally, TcpListener::listen uses the same call to ::bind as sf::UdpSocket, so it should work the same.

I just opened #1658 to add documentation on that topic, closing this ticket.
