MPI_DUP_FN(3) LAM/MPI MPI_DUP_FN(3)NAMEMPI_DUP_FN - Built-in MPI function to simple-mindedly copy communica‐
tor 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 func‐
tion (see the "See also" section, below), which provides the same func‐
tionality. 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_func‐
tion , 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 docu‐
ments 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/sow‐
ing/sowing.tar.gz ), the initial formatting, and some initial text for
most of the MPI-1 man pages.
