[mpich-discuss] Deprecated C++ bindings

Up to now I've been using this in my C++ code:

MPI_Comm_set_errhandler(intercom, MPI::ERRORS_THROW_EXCEPTIONS);

and hoping the MPI function calls would throw MPI::Exception when there is a problem.

Is the recommended approach now just to test the return values from the functions?

Using 4.0rc3.
