| MPI_FILE_GET_GROUP(fh, group) |
| IN fh | file handle (handle) |
| OUT group | group that opened the file (handle) |
C binding
int MPI_File_get_group(MPI_File fh, MPI_Group *group)
Fortran 2008 binding
MPI_File_get_group(fh, group, ierror)
TYPE(MPI_File), INTENT(IN) :: fh
TYPE(MPI_Group), INTENT(OUT) :: group
INTEGER, OPTIONAL, INTENT(OUT) :: ierror
Fortran binding
MPI_FILE_GET_GROUP(FH, GROUP, IERROR)
INTEGER FH, GROUP, IERROR
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.
| MPI_FILE_GET_AMODE(fh, amode) |
| IN fh | file handle (handle) |
| OUT amode | file access mode used to open the file (integer) |
C binding
int MPI_File_get_amode(MPI_File fh, int *amode)
Fortran 2008 binding
MPI_File_get_amode(fh, amode, ierror)
TYPE(MPI_File), INTENT(IN) :: fh
INTEGER, INTENT(OUT) :: amode
INTEGER, OPTIONAL, INTENT(OUT) :: ierror
Fortran binding
MPI_FILE_GET_AMODE(FH, AMODE, IERROR)
INTEGER FH, AMODE, IERROR
MPI_FILE_GET_AMODE returns, in amode,
the access mode of the file associated with fh.
Example
In Fortran 77, decoding an amode bit vector will
require a routine such as the following:
This routine could be called successively to decode amode,
one bit at a time. For example, the following code fragment would
check for MPI_MODE_RDONLY.
