MPI_File_get_group - Returns the group of processes that
       opened the file


SYNOPSIS

       C:

            #include "mpi.h"

            int MPI_File_get_group(MPI_File fh, MPI_Group *group)

       Fortran:

            INCLUDE "mpif.h" (or USE MPI)

            INTEGER fh, group, ierror

            CALL MPI_FILE_GET_GROUP(fh, group, ierror)


DESCRIPTION

       MPI_File_get_group returns a duplicate of the group of the
       communicator used to open the file associated with fh.
       The group is returned in group. The user is responsible
       for freeing group.

       This routine accepts the following arguments:

       fh        Specifies the file handle (handle)

       group     Returns the group that opened the file (handle)

       ierror    Specifies the return code value for successful
                 completion, which is in MPI_SUCCESS.
                 MPI_SUCCESS is defined in the mpif.h file.

   Notes for Fortran
       All MPI objects (for example, MPI_Datatype, MPI_Comm,
       MPI_File) are of type INTEGER.
