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.
