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.
