Detailed Description

device I/O subsystem

The Device System is designed as simple and minimum layer to help communication between applications and drivers.

The Device System provide five interfaces to driver:

open, open a device
close, close a device
read, read some data from a device
write, write some data to a device
control, send some control command to a device
