Default MPI Communicator in C++

Dearl all,

I've read many questions about this issue: what it the preferred way of obtaining MPI_COMM_WORLD in C++?

In the answer I read that there should be a mpi_comm_world() in dolfin::MPI, however it seems there is no such function.

What am I missing?

Thanks!

Apart from using MPI_COMM_WORLD the old fashioned way, obviously.

That function is for convenience in the python layer... i think it is fine to use MPI_COMM_WORLD in c++
