MPI_Send
========
.. include_body
:ref:`MPI_Send` |mdash| Performs a standard-mode blocking send.
SYNTAX
------
C Syntax
^^^^^^^^
.. code-block:: c
#include <mpi.h>
int MPI_Send(const void *buf, int count, MPI_Datatype datatype, int dest,
int tag, MPI_Comm comm)
Fortran Syntax
^^^^^^^^^^^^^^
.. code-block:: fortran
USE MPI
! or the older form: INCLUDE 'mpif.h'
MPI_SEND(BUF, COUNT, DATATYPE, DEST, TAG, COMM, IERROR)
<type> BUF(*)
INTEGER COUNT, DATATYPE, DEST, TAG, COMM, IERROR
Fortran 2008 Syntax
^^^^^^^^^^^^^^^^^^^
.. code-block:: fortran
USE mpi_f08
MPI_Send(buf, count, datatype, dest, tag, comm, ierror)
TYPE(*), DIMENSION(..), INTENT(IN) :: buf
INTEGER, INTENT(IN) :: count, dest, tag
TYPE(MPI_Datatype), INTENT(IN) :: datatype
TYPE(MPI_Comm), INTENT(IN) :: comm
INTEGER, OPTIONAL, INTENT(OUT) :: ierror
INPUT PARAMETERS
----------------
* ``buf``: Initial address of send buffer (choice).
* ``count``: Number of elements in send buffer (nonnegative integer).
* ``datatype``: Datatype of each send buffer element (handle).
* ``dest``: Rank of destination (integer).
* ``tag``: Message tag (integer).
* ``comm``: Communicator (handle).
OUTPUT PARAMETER
----------------
* ``ierror``: Fortran only: Error status (integer).
DESCRIPTION
-----------
:ref:`MPI_Send` performs a standard-mode, blocking send.
NOTE
----
This routine will block until the message is sent to the destination.
For an in-depth explanation of the semantics of the standard-mode send,
refer to the `MPI Standard <https://www.mpi-forum.org/docs/>`_.
