Is there a way to use a function from a static D library

lib.d:

extern(C) void printf(const char*, ...);

void foo() {
    printf("%s".ptr, "hi".ptr);   }

test.d:

extern(C) void _D3lib3fooFZv();

void main() {
    _D3lib3fooFZv();
}

Hehe.

Now, to be honest that is a good question. How to handle name 
mangling?
Maybe pragma(mangleOf, "") by Alex Petterson could help.


Thanks!

Why it works with "extern(C)", but not works with "extern(D)"?

I shouldn't paste this code in first place.

As far as I know and other folks mentioned there is no "clean" 
way to call function from D library without using .DI files or 
marking function in library as extern (C).

You can always look up symbol table like I did for this example.

Summary:
If you write library - you can mark function as extern (C) to 
call it later from other app without .DI fil.
You need to create .DI file if you use someone else library.
