35 .Nd object representing a class of devices
37 .Vt typedef struct devclass *devclass_t ;
41 object has two main functions in the system. The first is to manage
42 the allocation of unit numbers for device instances and the second is
43 to hold the list of device drivers for a particular bus type.
46 has a name and there cannot be two devclasses with the same name.
47 This ensures that unique unit numbers are allocated to device
