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.
