VFS is an abstraction layer on top of a 12 * more concrete file system. The purpose of a VFS is to allow client applications 13 * to access different types of concrete file systems in a uniform way. 14 * 15 * @image html dfs.png "Figure 4: Device Virtual File System Architecture" 16 * 17 * The DFS specifies an interface between the kernel and a concrete file system. 18 * Therefore, it is easy to add support for new file system types to the kernel 19 * simply by fulfilling the interface. 20 */ 21 22 /** 23 * @addtogroup DFS 24 */ 25 /*@{*/ 26 27 /** 28 * @defgroup Fd File Descriptor 29 * 30 */ 31 32 /** 33 * @defgroup FsApi File System API 34 */ 35 36 /** 37 * @defgroup FileApi File API 38 */ 39 40 /** 41 * @defgroup FsPosixApi File POSIX API 42 */ 43 44 /*@}*/ 45
