Here's the trick...
Say you create 2 characters under your account....
dumb & bumm - for the sake of argument...
say your account name is Jason
So you'd have 2 pfiles:
Baggins.Jason
Jessie.Jason
Now, if you were to try to login under either of those, I need
to make sure Baggins.Jason exists, no biggy there, access() would
work fine...
But say then you tried to login under a name that is not yours, say for
instance: Penthral
So it would look for Penthral.Jason
No biggie there, if that character isn't created, however, if that
happens to be under another name, say the pfile Penthral.Weirdo
already exists, well, I need to make sure that you dont create
that character... Hence the reason I'm checking against Penthral.*
So, I guess my real question is, to the best of my knowledge,
access() doesn't allow wildcards, am I mistaken in this?
And to the other repliers, thank you, I've been working on getting
this fixed for a while now, and that's actually the reason I went with this
less-effective ls method, as I could think of no other way to check to see
if a character exists under ANY account...
