iMeshP_getCommunicator()

void iMeshP_getCommunicator	(	iMesh_Instance	instance,
		int *	fcomm,
		MPI_Comm *	ccomm,
		int *	err
	)

Convert a fortran to C communicator Given a Fortran communicator, convert to a C communicator that can be passed back to iMeshP. Though this is an iMeshP function, it doesn't take an iMeshP Partition handle, since the (C) communicator is needed by the function that creates the partition. COMMUNICATION: None.

Parameters

instance	(In) Mesh instance to contain the partition.
fcomm	(In) Pointer to fortran communicator
ccomm	(Out) Pointer to the C communicator
err	(Out) Error code.
