NAME

       MPI_Rsend - Ready send.

SYNTAX

C Syntax
       #include <mpi.h>
       int MPI_Rsend(void *buf, int count, MPI_Datatype datatype, int dest,
	    int tag, MPI_Comm comm)

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

C++ Syntax
       #include <mpi.h>
       void Comm::Rsend(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 in send buffer (nonnegative integer).

       datatype  Datatype of each send buffer element (handle).

       dest	 Rank of destination (integer).

       tag	 Message tag (integer).

       comm	 Communicator (handle).

OUTPUT PARAMETER

       IERROR	 Fortran only: Error status (integer).

DESCRIPTION

       A  ready  send  may  only be called if the user can guarantee that a receive is already posted. It is an error if the receive is not posted
       before the ready send is called.

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
       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.

NAME

       MPI_Bsend_init - Builds a handle for a buffered send.

SYNTAX

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

Fortran Syntax
       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

C++ Syntax
       #include <mpi.h>
       Prequest Comm::Bsend_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 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++ 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
       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.
