Retrieve a list of all device instances currently in the devclass and return the list in *devlistp and the count in *devcountp. The memory allocated for the list should be freed using free(*devlistp, ...
The device object represents a piece of hardware attached to the system such as an expansion card, the bus which that card is plugged into, disk drives attached to the expansion card etc. The system d...
The devstat subsystem is an interface for recording device statistics, as its name implies. The idea is to keep reasonably detailed statistics while utilizing a minimum amount of CPU time to record th...
