How can I tell if a DLL is C or C++

I think I should know how to do this, but I don’t.

Hi @Chris_Halford

What would be the purpose of knowing the difference? A DLL is already compiled code.

I guess I’m more meaning the functions to access.
I need a C api to use declares

There is no specific C++ version.

It’s simply a DLL with functions, which look different as function names are encoded (mangled).
