NAME

       MPI_Send - Performs a standard-mode blocking send.

SYNTAX


C Syntax

       #include <mpi.h>
       int MPI_Send(void *buf, int count, MPI_Datatype datatype, int dest,
            int tag, MPI_Comm comm)

Fortran Syntax

       INCLUDE 'mpif.h'
       MPI_SEND(BUF, COUNT, DATATYPE, DEST, TAG, COMM, IERROR)
            <type>    BUF(*)
            INTEGER   COUNT, DATATYPE, DEST, TAG, COMM, IERROR

C++ Syntax

       #include <mpi.h>
       void Comm::Send(const void* buf, int count, const Datatype&
            datatype, int dest, int tag) const

INPUT PARAMETERS

       buf       Initial address of send buffer (choice).

       count     Number of elements send (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

       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-1 Standard.

ERRORS

       Almost  all MPI routines return an error value; C routines as the value
       of the function and Fortran routines in the last  argument.  C++  func-
       tions  do  not  return  errors.  If the default error handler is set to
       MPI::ERRORS_THROW_EXCEPTIONS, then on error the C++ exception mechanism
       will be used to throw an MPI:Exception object.
