MPI_File_get_group(3)MPI_File_get_group(3)NAMEMPI_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)
DESCRIPTIONMPI_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.
