 MPI_Rsend_init 3 "#OMPI_DATE#" "#PACKAGE_VERSION#" "#PACKAGE_NAME#"
 NAME
MPI_Rsend_init - Builds a handle for a ready send.


 SYNTAX
 C Syntax
#include <mpi.h>
int MPI_Rsend_init(const void *buf, int count, MPI_Datatype datatype,
 int dest, int tag, MPI_Comm comm, MPI_Request *request)




 Fortran Syntax
USE MPI
! or the older form: INCLUDE 'mpif.h'
MPI_RSEND_INIT(BUF, COUNT, DATATYPE, DEST, TAG, COMM, REQUEST,
 IERROR)
 <type> BUF(*)
 INTEGER COUNT, DATATYPE, DEST, TAG, COMM, REQUEST, IERROR




 Fortran 2008 Syntax
USE mpi_f08
MPI_Rsend_init(buf, count, datatype, dest, tag, comm, request, ierror)
 TYPE(*), DIMENSION(..), INTENT(IN), ASYNCHRONOUS :: buf

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




 INPUT PARAMETERS
 1i
buf
Initial address of send buffer (choice).

 1i
count
Number of elements sent (integer).

 1i
datatype
Type of each element (handle).

 1i
dest
Rank of destination (integer).

 1i
tag
Message tag (integer).

 1i
comm
Communicator (handle).


 OUTPUT PARAMETERS
 1i
request
Communication request (handle).

 1i
IERROR
Fortran only: Error status (integer).


 DESCRIPTION
Creates a persistent communication object for a ready mode send operation, 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++ functions 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.
