I known there is a bug with extern(C) in mixin template: https://issues.dlang.org/show_bug.cgi?id=12575

And I can see SimpleDllMain in core.sys.windows.dll, the mangled name is correct: DllMain
But my mixin template has wrong mangled name:

mixin template GetMetaData()
{
    extern(Windows) MetaData GetMetaData()
    {
        return MetaData();
    }
}

mixin GetMetaData;

I can see the mangled name is:
_D3app8__mixin911GetMetaDataWZS4zero7plugins8metadata8MetaData

main, DllMain, and WinMain are special cased...

for yours, I think you'll have to hack it with pragma(mangle)

 mixin template GetMetaData()
 {
     pragma(mangle, "GetMetaData") // or whatever maybe @0 ?
     extern(Windows) MetaData GetMetaData()
     {
         return MetaData();
     }
 }

 mixin GetMetaData;


I think.

Thanks. Anyone known any plan for issue 12575? It has been 3 years, it looks like not that hard to fix.
