.. _mpi_ssend_init:
MPI_Ssend_init
==============
.. include_body
:ref:`MPI_Ssend_init` |mdash| Builds a handle for a synchronous send.
SYNTAX
------
C Syntax
^^^^^^^^
.. code-block:: c
#include <mpi.h>
int MPI_Ssend_init(const void *buf, int count, MPI_Datatype datatype,
int dest, int tag, MPI_Comm comm, MPI_Request *request)
Fortran Syntax
^^^^^^^^^^^^^^
.. code-block:: fortran
USE MPI
! or the older form: INCLUDE 'mpif.h'
MPI_SSEND_INIT(BUF, COUNT, DATATYPE, DEST, TAG, COMM, REQUEST,
IERROR)
<type> BUF(*)
INTEGER COUNT, DATATYPE, DEST, TAG, COMM, REQUEST, IERROR
Fortran 2008 Syntax
^^^^^^^^^^^^^^^^^^^
.. code-block:: fortran
USE mpi_f08
MPI_Ssend_init(buf, count, datatype, dest, tag, comm, request, ierror)
TYPE(*), DIMENSION(..), INTENT(IN), ASYNCHRONOUS :: buf
INTEGER, INTENT(IN) :: count, dest, tag
TYPE(MPI_Datatype), INTENT(IN) :: datatype
TYPE(MPI_Comm), INTENT(IN) :: comm
TYPE(MPI_Request), INTENT(OUT) :: request
INTEGER, OPTIONAL, INTENT(OUT) :: ierror
INPUT PARAMETERS
----------------
* ``buf``: Initial address of send buffer (choice).
* ``count``: Number of elements to send (integer).
* ``datatype``: Type of each element (handle).
* ``dest``: Rank of destination (integer).
* ``tag``: Message tag (integer).
* ``comm``: Communicator (handle).
OUTPUT PARAMETERS
-----------------
* ``request``: Communication request (handle).
* ``ierror``: Fortran only: Error status (integer).
DESCRIPTION
-----------
Creates a persistent communication object for a synchronous mode send
operation, and binds to it all the arguments of a send operation.
A communication (send or receive) that uses a persistent request is
initiated by the function :ref:`MPI_Start`.
ERRORS
