#1楼主：00:一个USB协议中IRP取消的问题探讨
文章发表于：2008-10-10 11:06
下面是协议第五章PIPLES中的一段话：
A client can expect a variable-sized amount of data in an IRP. In this case, a short packet that does not
fill an IRP data buffer can be used simply as an in-band delimiter to indicate !end of unit of data.! The
IRP should be retired without error and the Host Controller should advance to the next IRP.
请问上面说的IRP retired是否就意味着这个短包的数据也被取消掉了呢，如果这样岂不是数据丢失了。
