MPI_Ssend

:ref:`MPI_Ssend` |mdash| Standard synchronous send.

SYNTAX

C Syntax

#include <mpi.h>

int MPI_Ssend(const void *buf, int count, MPI_Datatype datatype, int dest,
     int tag, MPI_Comm comm)

Fortran Syntax

USE MPI
! or the older form: INCLUDE 'mpif.h'
MPI_SSEND(BUF, COUNT, DATATYPE, DEST, TAG, COMM, IERROR)
     <type>  BUF(*)
     INTEGER COUNT, DATATYPE, DEST, TAG, COMM, IERROR

Fortran 2008 Syntax

USE mpi_f08
MPI_Ssend(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_Ssend` performs a synchronous-mode, blocking send. See the MPI Standard for more detailed information about such sends.
