A while ago, I noticed that our setup program didn't work with cvs wine. Somebody said "Oh, that's because named pipes are broken." Since then, the setup program works again with cvs wine, but I'm still curious about the state of named pipes.
The simple sequence CreateNamedPipe CreateFile seems to work under Windows, but not under Wine. Does Wine for some reason require a ConnectNamedPipe between the two? A very simple test is attached.
(BTW, I've been looking at the wineserver named pipe code a bit. Shame it's not better commented... at least it's small, so the lack of comments isn't too awful.) - Dan
