My apologies if this is the wrong list for this question... it seemed the most appropriate on the list.
I'm doing a proof-of-concept for my boss to demonstrate that we can port a large-ish application developed on Windows (using mostly crossplatform libraries like wxWindows, STLport, Xerces) to Linux using winelib to cover a few WIN32 API calls we've made.
I've just started into it, and have compiled a dozen files so far, but ran into trouble with the thread code. I cannot find SwitchToThread anywhere, not even in the winbase.h header file I expected it in. There are some changelogs to indicate that it exists, and the symbol does live in libntdll.dll.so, but I cannot find a header file that defines it.
Can anyone point me in the right direction?
Cheers,
Sean

- From what I can see, it doesn't appear to be in any header files, yet the function is there in kernel32, both the code and the spec file. The only thing that is anywhere near similiar is SwitchToThreadStack defined in thread.h. According to MSDN, it should be in winbase.h. Anyone know why it isn't?

Because someone forgot to update winbase.h, that's all. Use this patch:

Looking at MSDN, at the very bottom of SwitchToThread's remarks section it says: "To compile an application that uses this function, define the _WIN32_WINNT macro as 0x0400 or later." Should we put an #ifdef around its definition also, or is it not worth it?

I think it's not worth it. It seems we rarely put such checks in the headers although there are a couple (3 to be exact). It might be worth clarifying our position though. Anybody for or against?

Against. The features are always available in Wine anyway so the prototypes may as well be available too. If there's really an app out there that breaks because of an extra prototype it's easy to add a #ifdef at that point; but I doubt this will happen.
