MPI_Type_free_keyval - Frees the data type attribute key
       for the data type cache attribute


SYNOPSIS

       C:

            #include <mpi.h>

            int MPI_Type_free_keyval ( type_keyval )
            int *type_keyval;

       Fortran:

            INCLUDE "mpif.h" (or USE MPI)

            INTEGER type_keyval, ierror

            CALL MPI_TYPE_FREE_KEYVAL(type_keyval, ierror)


STANDARDS

       This function is defined in the MPI-2 standard.

       This release implements the MPI 1.2 standard, as
       documented by the MPI Forum in the spring 1997 release of
       MPI:  A Message Passing Interface Standard.


DESCRIPTION

       The MPI_Type_free_keyval routine frees the data type
       attribute key for the data type cache attribute.  This
       routine accepts the following parameter:

       type_keyval
                 Frees the integer key value (integer)

       ierror    Specifies the return code value for successful
                 completion, which is in MPI_SUCCESS.
                 MPI_SUCCESS is defined in the mpif.h file.


NOTES

       Key values are global (they can be used with any and all
       data types).
