MPI_Win_free_keyval - Frees the window attribute key for
       the window cache attribute


SYNOPSIS

       C:

            #include <mpi.h>

            int MPI_Win_free_keyval ( win_keyval )
            int *win_keyval;

       Fortran:

            INCLUDE "mpif.h" (or USE MPI)

            INTEGER win_keyval, ierror

            CALL MPI_WIN_FREE_KEYVAL(win_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_Win_free_keyval routine frees the window attribute
       key for the window cache attribute.  This routine accepts
       the following parameter:

       win_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
       windows).
