preference domains

[Rogelio M . Serrano Jr .]

In mac os x to which directories or list of directories or files do 
these tuples correspond?

current user : current application : current host
current user : current application : any host
current user : any application       : current host
current user : any application       : any host
any user       : current application : current host
any user       : current application : any host
any user       : any application       : current host
any user       : any application       : any host

In my implementation the search list is roughly 
userdomain/Library/Preferences, Local/Library/Preferences, 
Network/Library/Preferences, /System/Library/Preferences. It is in C 
for now and almost all of my projects are already using it and im 
rewriting it in objective-c. Automation and config is very easy.
