Join message

RFC 2811: Internet Relay Chat: Client Protocol
3.2.1 Join message


      Command: JOIN
   Parameters: ( <channel> *( "," <channel> ) [ <key> *( "," <key> ) ] )
               / "0"

   The JOIN command is used by a user to request to start listening to
   the specific channel.  Servers MUST be able to parse arguments in the
   form of a list of target, but SHOULD NOT use lists when sending JOIN
   messages to clients.

   Once a user has joined a channel, he receives information about
   all commands his server receives affecting the channel.  This
   includes JOIN, MODE, KICK, PART, QUIT and of course PRIVMSG/NOTICE.
   This allows channel members to keep track of the other channel
   members, as well as channel modes.

   If a JOIN is successful, the user receives a JOIN message as
   confirmation and is then sent the channel's topic (using RPL_TOPIC) and
   the list of users who are on the channel (using RPL_NAMREPLY), which
   MUST include the user joining.

   Note that this message accepts a special argument ("0"), which is
   a special request to leave all channels the user is currently a member
   of.  The server will process this message as if the user had sent
   a PART command (See Section 3.2.2) for each channel he is a member
   of.

                                   key "fubar" and &bar using no key.

   JOIN #foo,#bar fubar,foobar     ; Command to join channel #foo using
                                   key "fubar", and channel #bar using
                                   key "foobar".

   JOIN #foo,#bar                  ; Command to join channels #foo and
                                   #bar.

   JOIN 0                          ; Leave all currently joined
                                   channels.
