MPI_File_get_group(3)

NAME
     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.
