MPI_Bsend_init(3)

NAME
     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:

     buf            Specifies the initial address of the send 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.
