NAME

MPI_Send_init - Builds a handle for a standard send.

SYNTAX

C Syntax

#include <mpi.h>
int MPI_Send_init(void *buf, int count, MPI_Datatype datatype,
        int dest, int tag, MPI_Comm comm, MPI_Request *request)

Fortran Syntax

INCLUDE 'mpif.h'
MPI_SEND_INIT(BUF, COUNT, DATATYPE, DEST, TAG, COMM, REQUEST,
                IERROR)
        <type>  BUF(*)
        INTEGER REQUEST, COUNT, DATATYPE, DEST, TAG
        INTEGER COMM, REQUEST, IERROR

C++ Syntax

#include <mpi.h>
Prequest Comm::Send_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 to send (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 standard 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 or MPI_Startall.

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.
