g) what happens if same interface used by different DLLS. Is one instance still created?
Yes.
Are you sure? For instance, in Windows globals aren't merged on DLL loading, so if you've got something like: /*** foo.hpp ***/ template<typename T> struct foo { static T* get() { T t; return &t; } }; /*** main.cpp ***/ #include "foo.hpp" T* t1=foo<T>::get(); /*** dll1.cpp ***/ #include "foo.hpp" T* t2=foo<T>::get(); you'll get different t1 and t2 values. I don't see how you're able to prevent this behavior for the local static data of singleton_manager. Joaquín M López Muñoz Telefónica, Investigación y Desarrollo
