and compile and link to kernel32.lib

But I got the following compile error:

Any clues?

From what I can tell you're using the wide version, so try prototyping


it as GetUserDefaultLocaleNameW <- note the W

Otherwise you should really get
http://dsource.org/projects/bindings/wiki/WindowsApi , which has
prototypes for many windows functions. You just have to build and use
it with --version=Unicode if you want GetUserDefaultLocaleName to
alias itself to GetUserDefaultLocaleNameW.

Thanks for the link hey! :)
Otherwise I still get the same linking error with the W :(

It looks like that particular function does not have the A and W versions.

See this page:

http://msdn.microsoft.com/en-us/library/dd318136%28v=vs.85%29.aspx

And see this for an example of something that comes in W and A variety:

http://msdn.microsoft.com/en-us/library/dd317759%28v=VS.85%29.aspx

Note at the bottom the "Unicode and ANSI names" part.

Here is my new theory -- note that the function is only defined on Vista  
or later.  DMD does not use the same object format as Windows (i.e. Visual  
C++), so all libraries have to be "converted" to a form that dmd can link  
with.  Most of the relevant Windows lib files are already pre-converted  
and included in the dmd distribution under windows/lib.  I'd bet that the  
version of kernel32.lib that was used to generate this file is an XP  
version, which would not contain this function.

I'd recommend investigating how to replace that kernel32.lib with the  
Vista (or later) version (I'm sure someone will tell you here ;) or try  
using the predecessor function, which should be universally compatible  
(See the above noted documentation).

Well, I'll have to write a formal complaint to Google for making me

It's not in kernel32.lib distributed with DMD. You would have to
create an OMF import lib by calling implib /system kernel32.dll (your
own kernel32.dll) if you're actually using Vista or a newer OS and
then linking with that. But you can say goodbye to supporting Windows
older than Vista.

OTOH GetUserDefaultLCID /is/ in the kernel32.lib distributed with DMD.
So why not use that?

Lloyd, if the program you're writing is designed to be sold or distributed 
to the public then I'd highly recommend against doing anything that requires 
at least Vista. From what I've heard, the adoption rates of Vista and Win7 
haven't been very good and about half of the Windows systems out there are 
still XP and pretty much holding there. A *lot* of Windows users are 
deliberately sticking with XP, and you'll be loosing a lot of people.

Of course, if your software is only designed to be used internally by some 
company, or just for you own use, etc., then obviously it doesn't matter...

 Actually, Windows 7 is growing somewhat exponentially and XP is falling,


though that fall isn't accelerating too rapidly. However, XP still sits at
around 45%.

Yes and no!

On one hand I'm a fervent believer of all things Windows 7! :P

On the other hand my (learning) D project is about writing an installer. 
Which should just work with no unexpected dependencies!
I was telling to myself earlier today too that I should not use this 
function, just in case! :)

Typically, windows functions come in two varieties, the A and the W  
version.  This is hidden by a macro in C, so all you ever call is  
GetUserDefaultLocaleName (and that's how it is in the docs even).  But in  
D, which does not have a pre-processor, you must add the A (ascii) or W  
(wide) to the function name.  Try:

extern(Windows)
{
     int GetUserDefaultLocaleNameW(LPWSTR lpLocaleName, int cchLocaleName);
}
