MPI_Rsend_init(3)

NAME
     MPI_Rsend_init - Creates a persistent communication request for a ready
     send operation

SYNOPSIS
     C:

          #include <mpi.h>

          int MPI_Rsend_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::Rsend_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_RSEND_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_Rsend_init routine builds a handle for a ready 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.
