[OMPI users] Open MPI C++ class datatype

[Jack Bryan]

Dear All:
I need to transfer some data, which is C++ class with some vector<float> member 
data.
I want to use MPI_Bcast(buffer, count, datatype, root, comm);
May I use MPI_Datatype to define customized data structure that contain C++ 
class ? 
Any help is appreciated.
