NAME

SYNOPSIS

       #include <mpi.h>
       int MPI_Keyval_create(MPI_Copy_function *cpyfunc,
                            MPI_Delete_function *delfunc,
                            int *key, void *extra)

INPUT PARAMETERS

       cpyfunc
              - Copy callback function for keyval

       delfunc

       extra  - Extra state for callback functions

OUTPUT PARAMETER

       key    - key value for future access (integer)

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.

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.
