I am doing something similar for my accounts. Seperate account file with a
email validation. Haven't created an automated pfile/account cleaner yet,
but might get there. What I'm trying to do though is make sure that people
don't create multiple accounts by using the email address as a unique
identifier. Now in todays world with 300 free places to get email I know
this is only a deterent, but it's still something I want to do. I just don't
want the mud to hang when it scans through all the account files, especially
if we end up with several hundred or something from new players that didn't
stick around or what have you.
Any help with using pthreads or any other option would be helpful.
Thanks for the tip on fork() not passing stuff between instances. I didn't
know it wouldn't do that, especially since you can pass the output back and
forth using the descriptor.

I'm not sure how large your player base is, so I don't know how many
account
files you might be fly through but I had a couple of small suggestions.
That
might help you out with your not wanting duplicates and what not.
What I did back on my own mud's account code. I required my players to
supply valid email addresses. To accomplish this I had them input an email
in. The code then generated a random "verification code" and emailed it to
the player. The account then had 7 days from that time to enter that code
into one of there characters to validate their account. After which my
pfilecleaner would clean out any invalidated accounts.
Also to save some time again I'm not sure how you do your accounts. But I
gave each account it's own directory. Then in each folder had a
<accountname>.acc file in it. I stored just basic information in that
file:
#ACCOUNT
Name Sarix~
Email [EMAIL PROTECTED]
Code Verifyed~
Code_time 0
Pass rommailinglist~
Flags A
LogO 1037392543
Default Sarix~
Trust 210
#END
End
#$
That way when I had to scan I only had to open a small file and quickly
grab
the needed information out that. I never had to use threats or fork, for
any
of my account code or my pfilecleaner, (which was a scrip that ran through
my entire player file directory found accounts/pfiles that were old and
not
being used and would delete them.)
Figured I would throw out some ideas that might help.

Ok.. I'm working on an account system, and want to make sure that no two
accounts have the same email address. Don't want users having duplicate
accounts. The issue I'm having is that during account creation I'm
scanning
all the existing user accounts to see if any have the same address. I'm
using fork() so that I don't have the entire mud come to a screeching halt
while it scans, but for some reason, although everything in the fork()
seems
to be working fine, it doesn't set the d->connected correctly or process
the
nanny function again at the end the way I'm wanting it to. Ideas? Thansk!
