/* Instances:
|
|
|
|
|
|
|
|
As with IEEE1275, a device can be opened, creating an instance.
|
|
|
|
Instances provide more abstract interfaces to the underlying
|
|
|
|
hardware. For example, the instance methods for a disk may include
|
|
|
|
code that is able to interpret file systems found on disks. Such
|
|
|
|
methods would there for allow the manipulation of files on the
|
|
|
|
disks file system. The operations would be implemented using the
|
|
|
|
basic block I/O model provided by the disk.
|
|
|
|
|
|
|
|
This model includes methods that faciliate the creation of device
|
|
|
|
instance and (should a given device support it) standard operations
|
|
|
|
on those instances.
