[Rcpp-devel] Setting the R random seed from Rcpp

Dear Rcpp experts,

 I would like to be able to store the R random seed from a Rcpp
function and then reset it. In other words I would like to replicate
the following code in Rcpp:

savedSeed <- .Random.seed
x <- Rfunction(parameters1);

.Random.seed <- savedSeed
x1 <- Rfunction(parameters2);

where Rfunction simulates some random numbers and uses them
but with different parameter values.
Is it possible to do something similar in Rcpp?
Probably using GetRNGstate() and PutRNGstate()?
