MPI_File_set_info(3)

NAME
     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.
