MPI_File_set_info - Sets new values for hints
SYNOPSIS
C:
#include "mpi.h"
int MPI_File_set_info(MPI_File fh, MPI_Info info)
Fortran:
INCLUDE "mpif.h" (or USE MPI)
INTEGER fh, info, ierror
CALL MPI_FILE_SET_INFO(fh, info, ierror)
DESCRIPTION
MPI_File_set_info sets new values for the hints of the
file associated with fh. MPI_File_set_info is a
collective routine. The info object can be different on
each process, but any info entries that an implementation
requires to be the same on all processes must appear with
the same value in each process's info object.
MPI_File_set_info accepts the following arguments:
fh Specifies the file handle (handle).
info Specifies the object that contains the hints.
Many info items that an implementation can use
when it creates or opens a file cannot be
changed easily once the file has been created
or opened. Thus, an implementation can ignore
hints issued in this call that it would have
accepted in an open call.
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.
