MPI_DUP_FN(3) LAM/MPI MPI_DUP_FN(3) NAME
MPI_DUP_FN - Built-in MPI function to simple-mindedly copy communicator attributes. SYNOPSIS
#include <mpi.h> int MPI_DUP_FN(MPI_Comm comm, int key, void *extra, void *attrin, void *attrout, int *flag) INPUT PARAMETERS
comm - communicator (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 is deprecated. It has been replaced with an MPI-2 function (see the "See also" section, below), which provides the same functionality. This function is (or effectively is) a wrapper to the replacement function, anyway. User programs should use the MPI-2 replacement function instead of this function. Some functions are deprecated because their names did not conform to the stricter naming conventions of MPI-2; others are deprecated because they have been replaced with more flexible functionality. SEE ALSO
MPI_COMM_DUP_FN ADDITIONAL
Note that the C typedefs MPI_Copy_function and MPI_MPI_Delete_function are also deprecated, in favor of their new names - MPI_Comm_copy_function , MPI_Comm_delete_function . Additionally, the MPI constants MPI_NULL_COPY_FN and MPI_NULL_DELETE_FN are also deprecated in favor of their new names - MPI_COMM_NULL_COPY_FN and MPI_COMM_NULL_DELETE_FN . 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). http://www.mpi-forum.org/ 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/sow- ing/sowing.tar.gz ), the initial formatting, and some initial text for most of the MPI-1 man pages. LOCATION

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 key- vals 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. SEE ALSO
