That's because in this case you're using standard C++ mechanisms and there is nothing particularly special about Rcpp. So you should instead have a look at documentation on STL, in particular how algorithms (copy) work on containers (vectors) using iterators (begin/end), as well as operations on iterators and how they're similar to pointers.
