[Rcpp-devel] R random numbers vs c++

Is there a reason to prefer Rcpp::runif over the c++ rand() for, say,
accepting a state in a Markov chain simulation? Is one more random than
another? faster?

FWIW, the random-number stuff in C++11 appears to be greatly expanded:

This is discussed in some more detail in, for instance:

It's my understanding the Rcpp does not (yet?) support C++11.
