Thread: Filesystem

All three operating systems, using the data abstraction layer to hide the details of implementation, the system files. All three operating systems used to open, close, read, write, access to the file system, such as calls for the implementation of the organization of the statistical basis, regardless of which data files. Call FreeBSD, vfs, Solaris and its mechanisms ( "virtual file system") is the data structure vnode mitui principles, or "virtual node." Solaris all files or access vnode FreeBSD To do this, it was entrusted. Besides common files, the file information vnode pointer - System - specific information is included. Linux is a similar mechanism, which is also known as the vfs (for example, a "virtual file, and switch). Linux is the file - systems - and ode to retrieve data is an independent structure. This structure is similar to the vnode of Solaris / FreeBSD yonghapnida. (Note that the structure of the inode Get Solaris / FreeBSD, so this is a file - System - f rely on the system for data files). Linux is two different structure for a company for an inode for the file, as well as other projects. The combination of FreeBSD, Solaris, "vnode operations."



Vfs many types of file system is implemented using the system. That is the reason why not a single file system to access the operating system. Sueopseup other operating systems. Of course, this is the file system data structures and routines associated with the operating system and the need for a transplant vfs problem. All three operating systems, file systems, and using the stack. Table 2 of the operating system and file system types have been implemented, the system does not support any type of file to be displayed.
