NAME

MPI_Bsend_init − Builds a handle for a buffered send.

SYNTAX

C Syntax

#include <mpi.h>
int MPI_Bsend_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_BSEND_INIT(BUF, COUNT, DATATYPE, DEST, TAG, COMM, REQUEST,

IERROR)

<type>

BUF(*)

INTEGER

COUNT, DATATYPE, DEST, TAG,

INTEGER

COMM, REQUEST, IERROR

Fortran 2008 Syntax

USE mpi_f08
MPI_Bsend_init(buf, count, datatype, dest, tag, comm, request, ierror)

TYPE(*), DIMENSION(..), INTENT(IN), ASYNCHRONOUS :: buf

INTEGER, INTENT(IN) :: count, dest, tag

TYPE(MPI_Datatype), INTENT(IN) :: datatype

TYPE(MPI_Comm), INTENT(IN) :: comm

TYPE(MPI_Request), INTENT(OUT) :: request

INTEGER, OPTIONAL, INTENT(OUT) :: ierror

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 request for a buffered mode send, 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.
