I've been working on a new message reader, and I've found that the msg_area,
and it seems to me that the "mail" is a special case in that the msg_area.grp,
msg_ara.sub, etc. arrays don't seem to be defined for the "mail" area. Those
arrays seem to be only defined for the sub-boards. So, I don't think there is
a last-read pointer, etc. defined for the "mail" area. If you want to find the
last read message for a user in the "mail" area, you'll need to go through all
messages in the "mail" area, look for the ones written to the current logged-in
user, and look at the 'attr' field in the message headers and find the last one
that has the MSG_READ attribute set. For example, something like this:
var msgbase = new MsgBase("mail");
if (msgbase.is_open)
{
var lastReadMsgIdx = 0;
for (var i = 0; i < msgbase.total_msgs; ++i)
{
var msgHdr = msgbase.get_msg_header(true, i, true);
if ((msgHdr.to_ext == user.number) && ((msgHdr.attr & MSG_READ) ==
MSG_READ))
lastReadMsgIdx = i;
}
msgbase.close();
}
else
console.print("Uh-oh, failed to open personal mail!\r\n\1p");
