Detailed description:

!group=Network/Internet Relay Chat! !header=network.h!

The CL_IRCConnection class represents a socket connection to an IRC server. Upon construction it will connect to the server+port given and then parse each line written by the IRC server. Each time CL_System::keep_alive() is called, the CL_IRCConnection will emit the signals for those commands received.

Most IRC networks will expect the connecting IRC client to first send a "nick" command and then a "user" command, as part of the logon process. CL_IRCConnection will not do this, so the general logon procedure looks somewhat like this:

      CL_IRCConnection connection("irc.freenode.net", "6667");
      connection.send_nick("MyNick");
      connection.send_user("username", "our.hostname", "irc.freenode.net", "User Name");

IRC servers will occationally send a "ping" line, which have to be replied with a "pong" command. If this isn't done within some server specific timeout, the IRC network will disconnect the client. CL_IRCConnection will also not do this automatically, so its important you at least hook up the ping slot, to a function looking like this:

      void on_ping(const std::string &daemon1, const std::string &daemon2)
      { connection.send_pong(daemon1, daemon2); }
