Hi,

I'm trying to link against a DLL which exports a bunch of C functions. The issue is: C symbols do not have underscore prefix in Windows, but DMD sticks underscore in front of the symbol name. For example: `extern(C) void Foo()` becomes `_Foo`.

Is there a way to disable that underscore?

Thanks in advance,

Use extern(Windows), or the more general extern(System), which will expand to either extern(C) or extern(Windows), depending on the OS you target.

Great thanks, it helped in deed. I still wonder why, since I expected `extern(Windows)` to be equal to `__stdcall`, which should have produced a mangled name `?Foo@0` instead of `Foo`, and I can clearly see in the Dependency Walker, that there's no such symbol in the DLL.

Call methods and property C++ from D. Interface C++ and D and  their  interaction.
