.. _mpi_file_write_shared:
MPI_File_write_shared
=====================
.. include_body
:ref:`MPI_File_write_shared` |mdash| Writes a file using the shared file pointer
(blocking, noncollective).
SYNTAX
------
C Syntax
^^^^^^^^
.. code-block:: c
#include <mpi.h>
int MPI_File_write_shared(MPI_File fh, const void *buf, int count,
MPI_Datatype datatype, MPI_Status *status)
Fortran Syntax
^^^^^^^^^^^^^^
.. code-block:: fortran
USE MPI
! or the older form: INCLUDE 'mpif.h'
MPI_FILE_WRITE_SHARED(FH, BUF, COUNT, DATATYPE, STATUS, IERROR)
<type> BUF(*)
INTEGER FH, COUNT, DATATYPE, STATUS(MPI_STATUS_SIZE), IERROR
Fortran 2008 Syntax
^^^^^^^^^^^^^^^^^^^
.. code-block:: fortran
USE mpi_f08
MPI_File_write_shared(fh, buf, count, datatype, status, ierror)
TYPE(MPI_File), INTENT(IN) :: fh
TYPE(*), DIMENSION(..), INTENT(IN) :: buf
INTEGER, INTENT(IN) :: count
TYPE(MPI_Datatype), INTENT(IN) :: datatype
TYPE(MPI_Status) :: status
INTEGER, OPTIONAL, INTENT(OUT) :: ierror
INPUT/OUTPUT PARAMETER
----------------------
* ``fh`` : File handle (handle).
INPUT PARAMETERS
----------------
* ``buf`` : Initial address of buffer (choice).
* ``count`` : Number of elements in buffer (integer).
* ``datatype`` : Data type of each buffer element (handle).
OUTPUT PARAMETERS
-----------------
* ``status`` : Status object (status).
* ``ierror`` : Fortran only: Error status (integer).
DESCRIPTION
-----------
:ref:`MPI_File_write_shared` is a blocking routine that uses the shared
file pointer to write files. The order of serialization is not
deterministic for this noncollective routine.
ERRORS
