NAME

       MPI_WIN_DUP_FN  -  Built-in MPI function to simple-mindedly copy window
       attributes.

SYNOPSIS

       #include <mpi.h>
       int MPI_WIN_DUP_FN(MPI_Win win, int key, void *extra,
                         void *attrin, void *attrout, int *flag)

INPUT PARAMETERS

       win    - window (handle)
       key    - key value (integer)
       extra  - extra state
       attrin - in value for attribute

OUTPUT PARAMETERS

       attrout
              - out value for attribute
       flag   - 1 if attribute copied successfully, 0 otherwise (logical)

NOTES

       This function blindly byte-copies attributes on  windows.   It  is  the
       default  atrribute-copying  function  for  windows.  This function will
       always return MPI_SUCCESS , and flag will always be set to 1.

       The actual copy is performed by the code

       *((void **) attrout) = attrin;

       If this simple assignment is not sufficient for  your  attributes,  you
       will  need  to  reassign  the  attribute-copying  function  on relevant
       keyvals on windows with the MPI_Win_keyval_create function.

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.

MORE INFORMATION

       For more information, please see the official MPI Forum web site, which
       contains the text  of  both  the  MPI-1  and  MPI-2  standards.   These
       documents contain detailed information about each MPI function (most of
       which is not duplicated in these man pages).

ACKNOWLEDGEMENTS

       The LAM Team would like the thank the MPICH Team for the handy  program
       to        generate        man        pages        ("doctext"       from
       ftp://ftp.mcs.anl.gov/pub/sowing/sowing.tar.gz    ),    the     initial
       formatting, and some initial text for most of the MPI-1 man pages.
