How to load a dll which is written by dlang with a c interface from a c program static/dynamic link on windows?

[ll via Digitalmars-d-learn]

e.g.

mydll.d:
import core.sys.windows.windows;
import core.sys.windows.dll;
 extern (C) export  int foo(ref int a[10],ref int b[10],ref int 
c[10])
{
        for(int i=0;i<10;i++)
        {
          c[10]=a[10]-b[10];
         }
        return 0;
}
mixin SimpleDllMain;
