Re: struct async-private - now tested and cleaned up

[Mike McCormack]

Hi Martin,

Each DLL should only import standard win32 api functions exported by
other (lower level) DLLs.

Where possible, the code should be able to be compiled and run on a
windows box. (ok, that excludes kernel, gdi, user, winsock, etc). That
is necessary to support dll=native linking.

In theory, we should only have to implement ntdll and the device
driver interfaces, then Microsoft's kernel, gdi, user, etc. would all
run on top of those too. Practically, some of our low level DLLs need
the wineserver interface.

Your client side register_async() func should be present in all the
dlls that use it because Windows has no equivilent export from NTDLL
(or any other dll).

Maybe you could create an inline function in a header?

My guess is that WinNT implements WSARecv() and ReadFile() using
something like NtReadFile().
