    Question TCP Server programming in C++ & Linux?

    Hi

    I hope you can help me. I'm used in tcp network programming with C++ & C# in Windows. Now I have to write a program for a raspberry pi and I have no idea where to start. This is my task:
    My Raspberry program shall open 2 tcp listener ports. When a client is connecting to one of the 2 ports then it shall receive data and sometimes it shall send back at the same port. When the client disconnects I need to have a message generated and then it shall wait for the next connection request. The very same shall happen with the second socket.

    I have already written such software for windows but there I could open 2 sockets and then I had either a delegate for the events (receiving, disconnecting) or some windows messages.

    I looked around google but I only found C-like examples which have one main function with an endless loop and the program exits when it disconnects. I'm not a big fan of such loops especially it doesn't seem to work that way with 2 ports at the same time. Is there any other way? Something event driven like I'm used in windows?

    boost.asio is a modern and portable c++ solution. If you have no stringent performance requirements, it seems also node.js works on Raspberry for an easier alternative.

    what do you mean ? in the end, any 'event based' system works with an 'endless' loop under the hood ...
