7.3 oskit_filesystem: File System Interface

 

The oskit_filesystem COM interface defines an interface for operating on a filesystem, which is a logical collection of files and a tree-structured namespace with a single root. The filesystem itself exists independent of any given namespace, for there is no notion of mounts in this interface. That functionality must be implemented at a higher level.

The oskit_filesystem COM interface inherits from IUnknown, and has the following additional methods:

statfs

Get attributes of this filesystem

sync

Write this filesystem's data to permanent storage

getroot

Get this filesystem's root directory

remount

Update this filesystem's mount flags

unmount

Forcibly unmount this filesystem

lookupi

Lookup a file by inode number
