MPI_File_close - Closes a file


SYNOPSIS

       C:

            #include "mpi.h"

            int MPI_File_close(MPI_File *fh)

       Fortran:

            INCLUDE "mpif.h" (or USE MPI)

            INTEGER fh, ierror

            CALL MPI_FILE_CLOSE(fh, ierror)


DESCRIPTION

       The MPI_File_close routine deallocates the file handle
       object and sets fh to MPI_FILE_NULL.  MPI_File_close first
       synchronizes file state (equivalent to performing an
       MPI_File_sync routine), then closes the file associated
       with fh.  The file is deleted if it was opened with access
       mode MPI_MODE_DELETE_ON_CLOSE (equivalent to performing an
       MPI_File_delete routine).  MPI_File_close is a collective
       routine.

       If the file is deleted when it is closed and there are
       other processes currently accessing the file, the status
       of the file and the behavior of future accesses by these
       processes are implementation dependent.

       The user is responsible for ensuring that all outstanding
       nonblocking requests and split collective operations
       associated with fh made by a process have completed before
       that process calls MPI_File_close.

       This routine accepts the following argument:

       fh     Specifies the file handle (handle)

       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.
