window_set_handle_c

	status.i4.v = window_set_handle_c(window_id.i2.v, handle.i1a.r)

	This routine allows the setting of a window's handle string which
	can be used for identification purposes.

	window_id	window ID (use WMNGR_BACKGROUND for background window)
	handle		null terminated handle string
			(up to WMNGR_MAX_HANDLE_LEN characters)

	This function returns status values as follows:

	OK			success
	CBS_INVARG		invalid window ID was specified or handle
				was too int
	CBS_NO_WINDOW		window doesn't exist
	CBS_MEMFAIL		dynamic memory allocation failure

	This function requires the following include files:

	cbslib_h, acnet_errors_h

	Related functions:

	window_read_handle_c, window_handle_to_id, window_construct(_c),
	intro_tv_windows

	C/C++ usage:

	static const char	handle[] = "Handle";
	short	window_id;
	int	status;

	status = window_set_handle_c(window_id,handle);
