NAME
MPI_Rsend_init - Builds a handle for a ready send.
SYNTAX
C Syntax
#include <mpi.h>
int MPI_Rsend_init(void *buf, int count, MPI_Datatype datatype,
int dest, int tag, MPI_Comm comm, MPI_Request *request)
Fortran Syntax
INCLUDE 'mpif.h'
MPI_RSEND_INIT(BUF, COUNT, DATATYPE, DEST, TAG, COMM, REQUEST,
IERROR)
<type> BUF(*)
INTEGER COUNT, DATATYPE, DEST, TAG, COMM, REQUEST, IERROR
C++ Syntax
#include <mpi.h>
Prequest Comm::Rsend_init(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 sent (integer).
datatype Type of each element (handle).
dest Rank of destination (integer).
tag Message tag (integer).
comm Communicator (handle).
OUTPUT PARAMETERS
request Communication request (handle).
IERROR Fortran only: Error status (integer).
DESCRIPTION
Creates a persistent communication object for a ready mode send opera-
tion, and binds to it all the arguments of a send operation.
A communication (send or receive) that uses a persistent request is
initiated by the function MPI_Start.
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
