	 * The following fields are used by the validation code. Since the

	 * that
	 *		a, The offsets point within the buffer
	 *		b, The last unicode character in the buffer is a NULL
	 * This ensures that when the worker does a wstrlen, it does not
	 * access memory beyond the InputBuffer.
	 *
	 * We also deal with variable length data which is not a string.
	 * Fortunately there are only three APIs that use such a structure.
	 * We special-case these apis. The APIs are
	 *		a, ServerAddIcon
	 *			We need to make sure that the icon buffer and icon length are
	 *			kosher. The worker will do the rest of the validation.
	 *		b, ServerAddEtc
	 *			We need to make sure that the buffer is consistent with the
	 *			number of etc mappings specified.
