NAME

       MPI_Rput  -  Put data into a memory window on a remote process and return a request handle
       for the operation.

SYNOPSIS

       int MPI_Rput(const void *origin_addr, int origin_count, MPI_Datatype
                   origin_datatype, int target_rank, MPI_Aint target_disp,
                   int target_count, MPI_Datatype target_datatype, MPI_Win
                   win, MPI_Request *request)

       MPI_Rput is similar to MPI_Put , except that it allocates a communication  request  object
       and  associates  it  with  the request handle (the argument request). The completion of an
       MPI_Rput operation (i.e., after the corresponding test or wait) indicates that the  sender
       is  now  free  to update the locations in the origin buffer. It does not indicate that the
       data is available at the target window. If remote completion is required, MPI_Win_flush  ,
       MPI_Win_flush_all , MPI_Win_unlock , or MPI_Win_unlock_all can be used.

INPUT PARAMETERS

       origin_addr
              - initial address of origin buffer (choice)
       origin_count
              - number of entries in origin buffer (nonnegative integer)
       origin_datatype
              - datatype of each entry in origin buffer (handle)
       target_rank
              - rank of target (nonnegative integer)
       target_disp
              - displacement from start of window to target buffer (nonnegative integer)
       target_count
              - number of entries in target buffer (nonnegative integer)
       target_datatype
              - datatype of each entry in target buffer (handle)
       win    - window object used for communication (handle)

OUTPUT PARAMETERS

       request
              - RMA request (handle)

THREAD AND INTERRUPT SAFETY

       This  routine is thread-safe.  This means that this routine may be safely used by multiple
       threads without the need for any user-provided thread locks.  However, the routine is  not
       interrupt  safe.   Typically, this is due to the use of memory allocation routines such as
       malloc or other non-MPICH runtime routines that are themselves not interrupt-safe.

NOTES FOR FORTRAN

       All MPI routines in Fortran (except for MPI_WTIME  and  MPI_WTICK  )  have  an  additional
       argument  ierr  at  the  end  of  the  argument list.  ierr is an integer and has the same
       meaning as the  return  value  of  the  routine  in  C.   In  Fortran,  MPI  routines  are
       subroutines, and are invoked with the call statement.

       All MPI objects (e.g., MPI_Datatype , MPI_Comm ) are of type INTEGER in Fortran.

ERRORS

       All  MPI  routines  (except MPI_Wtime and MPI_Wtick ) return an error value; C routines as
       the value of the function and Fortran routines in the last argument.  Before the value  is
       returned,  the current MPI error handler is called.  By default, this error handler aborts
       the MPI  job.   The  error  handler  may  be  changed  with  MPI_Comm_set_errhandler  (for
       communicators),  MPI_File_set_errhandler  (for files), and MPI_Win_set_errhandler (for RMA
       windows).  The MPI-1 routine MPI_Errhandler_set may be used but  its  use  is  deprecated.
       The  predefined  error  handler  MPI_ERRORS_RETURN may be used to cause error values to be
       returned.  Note that MPI does not guarentee that an  MPI  program  can  continue  past  an
       error; however, MPI implementations will attempt to continue whenever possible.

       MPI_SUCCESS
              - No error; MPI routine completed successfully.
       MPI_ERR_ARG
              -  Invalid  argument.  Some argument is invalid and is not identified by a specific
              error class (e.g., MPI_ERR_RANK ).
       MPI_ERR_COUNT
              - Invalid count argument.  Count arguments must be non-negative; a count of zero is
              often valid.
       MPI_ERR_RANK
              -  Invalid  source or destination rank.  Ranks must be between zero and the size of
              the  communicator  minus  one;  ranks  in  a  receive  (  MPI_Recv  ,  MPI_Irecv  ,
              MPI_Sendrecv , etc.) may also be MPI_ANY_SOURCE .

       MPI_ERR_TYPE
              -   Invalid   datatype   argument.    May   be  an  uncommitted  MPI_Datatype  (see
              MPI_Type_commit ).
       MPI_ERR_WIN
              - Invalid MPI window object
