MPI_Send(3OpenMPI)														MPI_Send(3OpenMPI)

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.

       Before the error value is returned, the current MPI error handler is called. By default, this error handler aborts the MPI job, except  for
       I/O  function  errors. The error handler may be changed with MPI_Comm_set_errhandler; the predefined error handler MPI_ERRORS_RETURN may be
       used to cause error values to be returned. Note that MPI does not guarantee that an MPI program can continue past an error.
