C++ has mo language support for packaging APIs except classes and header file.

 

Casting is a necessary evil. Old-Style C provides casting syntax that enables you to cast anything to anything.

 

If your class has virtual function and you need to invoke the default C++ constructor from a DLL other than the one your class is delivered in, then you need to specify, and export, a default C++ Constructor.

 

Constructor need you to create virtual function table and the information required is all inside your DLL.

 

Is it Easy or Hard? too simple.
