MPI_File_get_info - Returns a new information object
SYNOPSIS
C:
#include "mpi.h"
int MPI_File_get_info(MPI_File fh, MPI_Info *info_used)
Fortran:
INCLUDE "mpif.h" (or USE MPI)
INTEGER fh, info_used, ierror
CALL MPI_FILE_GET_INFO(fh, info_used, ierror)
DESCRIPTION
MPI_File_get_info returns a new information object
containing the hints of the file associated with fh. The
current setting of all hints actually used by the system
related to this open file is returned in info_used. The
user is responsible for freeing info_used by using
MPI_Info_free.
MPI_File_get_info accepts the following arguments:
fh Specifies the file handle (handle).
info_used Returns the new information object (handle).
The object returned in info_used will contain
all hints currently active for this file.
Because the system might not recognize some
hints set by the user, and might recognize
other hints that the user has not set, this
set of hints can be greater or smaller than
the set of hints passed to MPI_File_open,
MPI_File_set_view, and MPI_File_set_info.
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.
