   33: .Dt DEVCLASS 9
   34: .Os
   35: .Sh NAME
   36: .Nm devclass
   37: .Nd object representing a class of devices
   38: .Sh SYNOPSIS
   39: .Vt typedef struct devclass *devclass_t ;
   40: .Sh DESCRIPTION
   41: The
   42: .Dv devclass
   43: object has two main functions in the system.  The first is to manage
   44: the allocation of unit numbers for device instances and the second is
   45: to hold the list of device drivers for a particular bus type.
   46: Each
   47: .Dv devclass
   48: has a name and there cannot be two devclasses with the same name.
   49: This ensures that unique unit numbers are allocated to device
   50: instances.
