           Summary: After CreateNamedPipe and ReadFile, CancelIO returns

          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED

Test case output, source code

Call CreateNamedPipe with FILE_FLAG_OVERLAPPED and PIPE_ACCESS_INBOUND, then do
a ReadFile after someone has connected (in this case, just a CreateFile in the
same thread). Now this read would normally return fine, if we just waited for
the data to appear, however, if for whatever reason we have to stop waiting,
i.e. using a CancelIO call, then the CancelIO returns false on Wine. It returns
true on Windows. The problem is not with CancelIO, but rather with
NtCancelIoFile, as the attached test case will show. (NtCancelIoFile should
return 0 on Wine -- as it does on Windows -- instead it returns 192, which
confuses the CancelIO and makes it return false.) Please do not patch CancelIO
to just map the 192 to a true, this is not right! The problem is with
NtCancelIoFile (or somewhere within it).
