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-copy
ing 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 For
tran, 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.

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 ini
tial formatting, and some initial text for most of the
MPI-1 man pages.
