This code makes a one way info channel. it is for
the c code to broadcast informative messages to the populace.
Messages CAN NOT be sent by a PC, NPC, or mob.
it is fairly simple and is very easy to implement.

all you need to do is:

some where (i put it in act.comm.c) add
void do_infonet(char *message, int level)
{
  struct descriptor_data *i;

  /* first, set up string */
  sprintf(buf, "Info-> '%s'", message);

  /* now send all the string out */
  for(i=descriptor_list; i; i=i->next)
  {
    if(STATE(i)==CON_PLAYING && i->character &&
      !PRF_FLAGGED(i->character, PRF_NOINFO) &&
      !PLR_FLAGGED(i->character, PLR_WRITING) &&
      !ROOM_FLAGGED(i->character->in_room, ROOM_SOUNDPROOF))
    {
      switch(level)
      {
      case INFONET_IMP://implementor level
        if(GET_LEVEL(i->character)>=LVL_IMPL)
        {
          if(COLOR_LEV(i->character)>=C_SPR)
            send_to_char(KCYN, i->character);
          send_to_char(buf, i->character);
          if(COLOR_LEV(i->character)>=C_SPR)
            send_to_char(KNRM, i->character);
        }
        break;
      case INFONET_IMM://immortal and above
        if(GET_LEVEL(i->character)>=LVL_IMMORT)
        {
          if(COLOR_LEV(i->character)>=C_SPR)
            send_to_char(KCYN, i->character);
          send_to_char(buf, i->character);
          if(COLOR_LEV(i->character)>=C_SPR)
            send_to_char(KNRM, i->character);
        }
        break;
      case INFONET_ALL://all else
        if(COLOR_LEV(i->character)>=C_SPR)
          send_to_char(KCYN, i->character);
        send_to_char(buf, i->character);
        if(COLOR_LEV(i->character)>=C_SPR)
          send_to_char(KNRM, i->character);
        break;
      default:
        log("SYSERR: Unknown level %d in do_info.", level);
        return;
      }
    }
  }
}

and at the top of that file add
void do_infonet(char *message, int level);

add this to the command table in interpreter.c:
  { "noinfo"   , POS_DEAD    , do_gen_tog  , 0, SCMD_NOINFO },


in structs.h add
#define PRF_NOINFO (1 << 19) /* Can't hear infonet */
and
/* Infonet levels */
#define INFONET_IMP	0
#define INFONET_IMM	1
#define INFONET_ALL	2


in do_gen_tog change
     {"Autoexits disabled.\r\n",
    "Autoexits enabled.\r\n"}
to
    {"Autoexits disabled.\r\n",
    "Autoexits enabled.\r\n"},
    {"Info Channel disabled.\r\n",
    "Info Channel enabled.\r\n"}
and add
  case SCMD_NOINFO:
    result = PRF_TOG_CHK(ch, PRF_NOINFO);
    break;
to the big switch statament

now just type
  do_infonet(string_message_, infonet_level_define);
and if you have not done so already put
  extern void do_infonet(char *message, int level);
at the top of that file(unless it is the same file as the function body)

two messages i send are
 sprintf(buf, "Meet a brand new player thief: %s. Why don't you greet him warmly...", GET_NAME(ch));
 do_infonet(buf1,INFONET_ALL);
and
 sprintf(buf, "Meet a brand new player killer: %s. Why don't you greet him hime a nice hand or a severe contusion...", GET_NAME(ch));
 do_infonet(buf1,INFONET_ALL);
