推荐答案

C不支持你所追求的 - 在需要它，它听起来像什么是错的与您的设计。如果是除pretting流那么应该有与标识符早上indicateds后面的流中的结构的信息流中。

C does not support what you are after - and in requiring it it sounds like something is wrong with your design. If you are interpretting a stream then there should be and identifier early on in the stream that indicateds the structure in the stream that follows.
