std::vector of sockets [c++]

[paz]

I've constructed a vector of sf::TcpSockets however I can't push a socket back onto the vector.

Running:

• Fedora 24 64 bit
• libstdc++.so.6.0.22
• sfml-2.3.2

Error:

Code: [Select]

/usr/include/c++/6.2.1/ext/new_allocator.h:120:4: error: use of deleted function ‘sf::TcpSocket::TcpSocket(const sf::TcpSocket&)’

SFML socket classes are neither copyable nor movable (will change in SFML 3), so they can't be stored directly in a container. A simple solution is to store pointers to sockets.

std::vector<std::unique_ptr<sf::TcpSocket>> sockets;

Ah okay thanks for the quick reply, my fault for not reading the error properly.

Maybe update the docs to make this a bit clearer?

A selector is not a socket container. It only references (points to) the sockets that you add, it doesn't store them. There is no way to retrieve or count the sockets that you put inside. Instead, it is up to you to have your own separate socket storage (like a std::vector or a std::list).

I know it's OT a bit, but if I were you, I would not write server in C++. SFML/Network is great for p2p connections and clients, but C++ itself doesn't really fit server role. If you know JS, node.js is great to write such applications as it scales well and has simillar syntax.

(will change in SFML 3)

Sorry for detract the thread but, ¿Any hints/plans about when SFML 3 will be released?

[Laurent]

No. It hasn't started yet, so we're far from talking about a release date.
