RedHat 9 (Linux i386) - man page for mpi_win_dup_fn (redhat section 3)

MPI_WIN_DUP_FN(3)			     LAM/MPI				MPI_WIN_DUP_FN(3)

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_cre-
       ate function.

NOTES FOR FORTRAN
       All MPI routines in Fortran (except for MPI_WTIME and MPI_WTICK ) have an additional argu-
       ment 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 for-
       matting, and some initial text for most of the MPI-1 man pages.
