MPI_Send(3)

NAME
     MPI_Send - Performs a basic send operation

SYNOPSIS
     C:

          #include <mpi.h>

          int MPI_Send( buf, count, datatype, dest,
          tag, comm )
          void             *buf;
          int              count, dest, tag;
          MPI_Datatype     datatype;
          MPI_Comm         comm;


     C++:

          #include <mpi.h>

          void Comm::Send(
          const void*       buf,
          int               count,
          const Datatype&   datatype,
          int               dest,
          int               tag) const


     Fortran:

          INCLUDE "mpif.h" (or USE MPI)

          <type> BUF(*)
          INTEGER count, datatype, dest, tag, comm, ierror

          CALL MPI_SEND(buf, count, datatype, dest, tag, comm, ierror)


STANDARDS
     This release implements the MPI 1.2 standard, as documented by the MPI
     Forum in the spring 1997 release of MPI:  A Message Passing Interface
     Standard.

DESCRIPTION
     The MPI_Send routine performs a basic send operation.  This routine
     accepts the following parameters:

     buf       Specifies the initial address of the send buffer (choice)

     count     Specifies the number of elements in the send buffer
               (nonnegative integer)
     datatype  Specifies the data type of each send buffer element (handle)

     dest      Specifies the rank of the destination (integer)

     tag       Specifies the message tag (integer)

     comm      Specifies the communicator (handle)

     ierror    Specifies the return code value for successful completion,
               which is in MPI_SUCCESS.  MPI_SUCCESS is defined in the mpif.h
               file.

NOTES
     This routine may block until the message is received.

     All MPI routines in Fortran (except for MPI_Wtime(3) and MPI_Wtick(3) )
     have an additional ierr argument at the end of the argument list.  ierr
     is an integer and has the same meaning as the return value of the routine
     in C.  In Fortran, MPI routines are subroutines and are invoked with the
     CALL statement.  Additionally, in Fortran, all MPI objects (for example,
     MPI_Datatype and MPI_Comm) are of type integer.
