MPI_File_write_all_end

:ref:`MPI_File_write_all_end` |mdash| Writes a file starting at the locations specified by individual file pointers; ending part of a split collective routine (blocking).

SYNTAX

C Syntax

#include <mpi.h>

int MPI_File_write_all_end(MPI_File fh, const void *buf, MPI_Status *status)

Fortran Syntax

USE MPI
! or the older form: INCLUDE 'mpif.h'
MPI_FILE_WRITE_ALL_END(FH, BUF, STATUS, IERROR)
     <type>  BUF(*)
     INTEGER FH, STATUS, IERROR

Fortran 2008 Syntax

USE mpi_f08
MPI_File_write_all_end(fh, buf, status, ierror)
     TYPE(MPI_File), INTENT(IN) :: fh
     TYPE(*), DIMENSION(..), INTENT(IN), ASYNCHRONOUS :: buf
     TYPE(MPI_Status) :: status
     INTEGER, OPTIONAL, INTENT(OUT) :: ierror

INPUT/OUTPUT PARAMETER

  • fh: File handle (handle).

INPUT PARAMETER

  • buf: Initial address of buffer (choice).

OUTPUT PARAMETERS

  • status: Status object (status).
  • ierror: Fortran only: Error status (integer).

DESCRIPTION

:ref:`MPI_File_write_all_end` is the ending part of a split collective routine that stores the number of elements actually written into the file associated with fh from the user's buffer buf in status. :ref:`MPI_File_write_all_end` blocks until the operation initiated by :ref:`MPI_File_write_all_begin` completes. The data is written into those parts of the file specified by the current view. All other fields of status are undefined.

NOTES

All the nonblocking collective routines for data access are "split" into two routines, each with _begin or _end as a suffix. These split collective routines are subject to the semantic rules described in Section 9.4.5 of the MPI-2 standard.
