Actually, even more. It's obvious that WINE leaves *tons* of stuff 
unimplemented. CreateFile() does not update performance counters, doesn't 
check group policy, probably doesn't do *any* sort of security checks 
(beyond what Linux does), doesn't write audit logs, and maybe doesn't 
support UNC path names, probably doesn't support the various flags that 
CreateFile() natively supports like surpressing read-ahead or locking the 
file from deletion, probably doesn't support compressed or encrypted files, 
doesn't update any sort of USN logs, and so on.

So it's clear it's not necessary to duplicate the API precisely. You only 
have to duplicate it well enough to fool the software using it. You probably 
don't have to distinguish between (for example) not having permission to 
open the file and not having permission to traverse the directories above 
the file.
