MPI_Bsend_init - Creates a persistent communication
request for a buffered send
SYNOPSIS
C:
#include <mpi.h>
int MPI_Bsend_init( buf, count, datatype, dest, tag,
comm,
request )
void *buf;
int count;
MPI_Datatype datatype;
int dest;
int tag;
MPI_Comm comm;
MPI_Request *request;
C++:
#include <mpi.h>
Prequest Comm::Bsend_init(
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,
request, ierror
CALL MPI_BSEND_INIT(buf, count, datatype, dest,
tag, comm, request, 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_Bsend_init routine creates a persistent
communication request for a buffered send operation. This
routine accepts the following parameters:
buffer (choice)
count Specifies the number of elements sent
(integer)
datatype Specifies the type of each element (handle)
dest Specifies the rank of the destination
(integer)
tag Specifies the message tag (integer)
comm Specifies the communicator (handle)
request Returns the communication request (handle)
ierror Specifies the return code value for
successful completion, which is in
MPI_SUCCESS. MPI_SUCCESS is defined in the
mpif.h file.
