SYNTAX
------

C Syntax
^^^^^^^^

.. code-block:: c

    int MPI_Isend(const void* buf, int count, MPI_Datatype datatype, int
        dest, int tag, MPI_Comm comm, MPI_Request* request)

    int MPI_Isend_c(const void* buf, MPI_Count 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_ISEND(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_Isend(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

    MPI_Isend(buf, count, datatype, dest, tag, comm, request, ierror)
    	TYPE(*), DIMENSION(..), INTENT(IN), ASYNCHRONOUS :: buf
    	INTEGER(KIND=MPI_COUNT_KIND), INTENT(IN) :: count
