How do I pass a unique_ptr argument to a constructor or a function?

Question

I\'m new to move semantics in C++11 and I don\'t know very well how to handle unique_ptr parameters in constructors or functions. Consider this class referenc

Answer 1

Base(Base::UPtr n):next(std::move(n)) {}

should be much better as

Base(Base::UPtr&& n):next(std::forward(n)) {}

and

void setNext(Base::UPtr n)

should be

void setNext(Base::UPtr&& n)

with same body.

And ... what is evt in handle() ??
