On each of the referenced imports . if either the timestamp or the preferred address does not match those of the loaded dll , the helper function will assume the bound iat is out of date and will proceed as if the bound iat does not exist 如果时间戳或首选地址与加载的dll的时间戳或首选地址不匹配,则helper函数将假定绑定的iat已经过期并继续执行,就像绑定的iat不存在一样。
