MPI_File_get_info(3)

NAME
     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.
