逻辑文件系统
Examples
- The kernel of the file system is composed of two parts : the virtual file system and the logic file systems
这样就为用户程序提供了一个统一的、抽象的、虚拟的文件系统接口。 - There are three layers in deltafile , virtual file system 、 logic file system and buffer cache . besides , deltafile provides the posix api interface
为了对用户透明的实现多种不同文件系统支持的功能, deltafile中采用了虚拟文件系统和逻辑文件系统相分离的体系结构。 - First it supports the system call interfaces complied with the posix standard , which make convenience to the porting process to delta os for applications . second , delta file 3 . 0 offers the entire supports to the fat logic file system format , and make it suitable in multitasks environment through technique process . once more , delta file 3 . 0 support the flexible virtual file system interface and drive manage interface to make update easier
首先,其系统调用接口遵循posix规范,以便于应用向deltaos进行移植;其次, deltafile3 . 0提供了对fat全系列逻辑文件系统格式(含fat12 、 fat16 、 fat32 )的完全支持,并通过改造将fat这种源于单任务操作系统dos的文件系统标准应用于多任务环境;此外, deltafile3 . 0提供了灵活的虚拟文件系统接口和设备驱动管理接口,便于未来的升级和扩展。
