is only one directory tree that manages several disk partitions, regardless of the operating system. Structurally, the tree catalogs on each disk partition are not necessarily tied.If this is not easy to understand, let me cite an example:There is a hard disk, divided into 4 partitions,/;/BOOT;/USR and Windows, respectively, the fatfor/and/boot or/and/usr, they are dependent, and for/boot and/usr are side-

completely confused with the channel.According to my observation, the pipeline should be a special stack-type queue, and Its Entry and Exit have been fixed and pointed to at the time of creation. Its main function is to provide a dedicated queue buffer for the filter. The filter entry requires an MTS queue to provide the buffer function, because the filter exists as the internal processing mechanism of the message system, and the processing delay mus
