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.

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/sowing/sowing.tar.gz  ),  the  initial
       formatting, and some initial text for most of the MPI-1 man pages.
