.. _mpi_bsend_init:
MPI_Bsend_init
==============
.. include_body
:ref:`MPI_Bsend_init` |mdash| Builds a handle for a buffered send.
SYNTAX
------
C Syntax
^^^^^^^^
.. code-block:: C
#include <mpi.h>
int MPI_Bsend_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_BSEND_INIT(BUF, COUNT, DATATYPE, DEST, TAG, COMM, REQUEST, IERROR)
<type> BUF(*)
INTEGER COUNT, DATATYPE, DEST, TAG,
INTEGER COMM, REQUEST, IERROR
Fortran 2008 Syntax
^^^^^^^^^^^^^^^^^^^
.. code-block:: Fortran
USE mpi_f08
MPI_Bsend_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 sent (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 request for a buffered mode send, 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
------
.. include:: ./ERRORS.rst
