MPI_Rsend - Provides a basic ready send operation


SYNOPSIS

       C:

            #include <mpi.h>

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

       C++:

            #include <mpi.h>

            void Comm::Rsend(
            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_RSEND(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_Rsend routine provides a basic ready 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


       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.
