You can translate the communicator from Fortran to C using the MPI_COMM_F2C
routine.

Hi,
I have problems running a Fortran program which is calling a C library
with OpenMPI.
The problem is that the Fortan part has a communicator which is passed
to the C library.
And if I understand the headers right a communicator is an integer in
fortran, but a struct on the C side of openmpi.
Is there a way to translate/cast these communicators?
best regards,
Samuel
