Help with /?? stuff

[Shachar Shemesh]

Hi,

I'll clarify my specific predicament.

It seems that when MoveFileEx is called with 
"MOVEFILE_DELAY_UNTIL_REBOOT" flag, an entry is written into the 
registry with the file names to rename. Windows being what it is, a 
MULTI_SZ entry is used in a way that is totally and utterly incopatible 
with the MULTI_SZ definition, but we'll leave that rant to another time.

The thing more interesting is that Windows, and as a result Wine, add 
"\??\" at the begining of the file name. This means that if I wanted to 
reanem C:\hello to C:\goodbye, the registry will get \??\C:\hello and 
\??\C:\goodbye. I tried passing this string directly into CreateFile, 
and no go (in other words, these are not valid file names, at least as 
far as Wine is concerned).

My question is whether anyone is familiar enough with the API to tell 
whether these are valid path names that are simply not understood by 
Windows, or whether I am supposed to strip them away, whether on Windows 
or on Wine?
