is recursive delete, when encountered is a directory, then enter the subdirectory, if the file encountered, then delete the file, if there is no content in the current directory, the upper directory is returned. After a further deep traversal, the entire directory tree is deleted. It is important to note that the root directory and its subdirectories need to be deleted differently, the root directory not only to delete itself, but also to make a modification to its parent directory, because it

asUsername N1 groupname_1 groupname_2 ... groupname_n1Indicates that the user username belongs to a N1 group, followed by each group nameThen enter an m to indicate that there are M files. The information for each file is then given in the formatfilename XXX User GroupRepresents a file name, permission, owning user, and owning group0OutputFor each set of dataOutputs a n*m matrix that represents each user's permissions on each file. The numbers are separated by spaces.Sample Input22AA 2 AA BBBB

Linux Kernel series-6. Memory paging mechanism for operating system development, linux Paging A. Overview The page size is 4 kb, and each table item occupies 4 bytes. The Register provides the physical base address of the page Directory. The page Directory provides the physical address of all the page tables, each page table provides the physical address of the p

The news system to the Huambo system to increase paging function, without modifying the database, just change a file, it is OK. It's even more perfect if you add a webediter to the background. I haven't added this yet. This example is in the background to enter the news, in the need to page the location Insert page break: {$html_page$} on it. The code is as fol

　　In the previous article introduced several multi-channel programming memory management mode, the Exchange memory management is most flexible and advanced. But there are a lot of major problems with this strategy, and the two most important issues are space waste and program size constraints. So what's the solution to the problem of swapping memory? The answer is paging, which is the "only way" that we solve for the exchange defect.One,

. Address Structure Known logical Address page number and in-page address Given a logical address space where the address is a and the page size is L, the page number P and the in-page address D (numbering starting from 0) can be evaluated as follows: Where INT is the divisible function, the mod is the remainder function. Example: The system has a page size of 1 KB and A = 2170 B, then P = 2,d = 122 can be obtained by the above formula. Page Table T
