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).

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.
