How to add constructors/destructors to an unnamed class?

Is there a way to declare a constructor or a destructor in an unnamed class? Consider the following 

void f()
{
    struct {
        // some implementation
    } inst1, inst2;

    // f implementation - usage of instances
}

Follow up question : The instances are ofcourse constructed (and destroyed) as any stack based object. What gets called? Is it a mangled name automatically assigned by the compiler?

Solution

  • You can not declare a constructor or destructor for an unnamed class because the constructor and destructor names need to match the class name. In your example, the unnamed class is local. It has no linkage so neither mangled name is created.
