MPI_File_close(3)MPI_File_close(3)NAMEMPI_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.
