If type == 1: Length of the following string, including closing zero byte. If the length including closing zero byte equals an odd value a second zero byte is added to the string so that an even value is achieved. Therefore, Len is calculated using ((StrLen+2) & ~1).
如果 Type == 1：下列字符串的长度，包括终止的零字符。如果这个长度包括终止的零字符产生一个奇数数值，则为了得到一个偶数数值，应给此字符串新增第二个空字符。因此 Len 通过((StrLen+2) & ~1)计算得出。
