I believe that ntdll should be used as a C run-time replacement as much
as possible, especially in the light of a more and more wide use of unicode
in Wine and necessity to have a direct way to manipulate unicode strings
The only question I have: in what header file all those ntdll C run-time
functions should be prototyped? It seems that NT DDK does not have an answer
on that question.

And the very next question arises how to resolve conflicts with prototypes
provided by an underlying system?

No, wineserver does not emulate anything.

Wineserver does not handle threading and such, it provides interprocess
handle management and synchronization mechanisms for Wine processes.

Not from the point of view of the ReactOS. Just look for imports of gdi32,
user32 and kernel32 on the real nt/w2k system.

Cygwin currently lacks a mechanism to transfer file handles between
processes (implementations of sendmsg and recvmsg are incomplete), and
therefore either they should be completed or some other way around should
