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 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.
