Even if each person's writing model is mostly influenced by others, the programmer usually blends many kinds of patterns into their own unique features, and if you know the author's programming preferences, read his code to get a better handle.When you read a code, you tend to take a top-down,: 'd cocoon approach. Through the tree structure of the recording layer, the programmer can gradually establish the

A file object that has already been opened is created in the kernel by an open system call, also called a file handle. The Open File List module contains a list, each list item is a struct struct file, and the information in the struct is used to represent the various state parameters of an open file.5, File_operations module.

We all know that NTFS-formatted Windows hard disk under Mac OS x system can only read can not write, this problem has been plagued by many new and old Mac users, the general solution is to install the NTFS plug-in to allow OS X to support NTFS-formatted hard disk write operations. In fact, after the release of OS X 10.9, OS X itself has the features of compatible and support NTFS files, but it is hidden by Apple, today PC6 Small
