   3  *
   4  * CMDNAME: chanflags
   5  * CMDLEVEL: QCMD_AUTHED
   6  * CMDARGS: 2
   7  * CMDDESC: Shows or changes the flags on a channel.
   8  * CMDFUNC: csc_dochanflags
   9  * CMDPROTO: int csc_dochanflags(void *source, int cargc, char **cargv);
  10  * CMDHELP: Usage: CHANFLAGS <channel> [<changes>]
  11  * CMDHELP: Shows or changes the status of channel flags, where:
  12  * CMDHELP: channel - channel to use
  13  * CMDHELP: changes - changes to apply to the channel flags in the usual +/- format, e.g. +c
  14  * CMDHELP:           to set +c and -c to remove it.
  15  * CMDHELP: Viewing the current flags requires operator (+o) access on the named channel.
  16  * CMDHELP: Changing the flags requires master (+m) access on the named channel.
  17  * CMDHELP: Valid channel flags are:
  18  * CMDHELP:  +a AUTOOP     Automatically ops any user who has op access when they join the
  19  * CMDHELP:                channel.  Same effect as giving all ops the +a chanlev flag.
  20  * CMDHELP:  +b BITCH      Prevents users who don't have operator access on the channel
  21  * CMDHELP:                from being opped (automatically deops them)
  22  * CMDHELP:  +c AUTOLIMIT  Enables automatic limit feature - updates the channel limit at
  23  * CMDHELP:                regular intervals to keep a certain number of free spaces.  This
  24  * CMDHELP:                can mitigate the effect of join floods.  See AUTOLIMIT.
  25  * CMDHELP:  +e ENFORCE    Enforces bans on the channel.  Any user who is banned will be
  26  * CMDHELP:                kicked automatically.
  27  * CMDHELP:  +f FORCETOPIC Prevents channel ops from changing the topic.  The SETTOPIC
  28  * CMDHELP:                command must be used instead.
  29  * CMDHELP:  +g AUTOVOICE  Automatically voices any user who has voice access when they join
  30  * CMDHELP:                the channel.  Same effect as giving all voices the +g chanlev flag.
  31  * CMDHELP:  +h ACH'MENTS  Display achievement announcements in channel.
  32  * CMDHELP:  +j JOINED     Causes Q to remain on the channel.  Cannot be removed.
  33  * CMDHELP:  +k KNOWNONLY  Any user who joins the channel who is not known (+k) will be kicked.
  34  * CMDHELP:                Unless channel mode +i is set they will be banned as well.
  35  * CMDHELP:  +p PROTECT    Any user with voice (+v) or operator (+o) access will have that
  36  * CMDHELP:                status enforced on the channel at all times.  Same effect as giving
  37  * CMDHELP:                all ops and voices the +p chanlev flag.
  38  * CMDHELP:  +t TOPICSAVE  Saves the topic when it changes.  Such saved topics can be restored
  39  * CMDHELP:                via settopic, or when the bot rejoins when a channel has been left
  40  * CMDHELP:                empty.
  41  * CMDHELP:  +v VOICEALL   Automatically grants voice (+v) on the channel to any user who enters,
  42  * CMDHELP:                unless they have quiet (+q) chanlev flag.
  43  * CMDHELP:  +w WELCOME    Sends the welcome message to users joining the channel.  See WELCOME.
  44  * CMDHELP: Note: Previous versions of Q included the facility to enforce limits and keys using
  45  * CMDHELP: +k and +l chanflags.  This functionality is now available via the CHANMODE command.
