| 33.Os FreeBSD 34.Sh NAME 35.Nm devclass 36.Nd object representing a class of devices 37.Sh SYNOPSIS 38.Dv typedef struct devclass *devclass_t; 39.Sh DESCRIPTION 40.Pp 41The 42.Dv devclass 43object has two main functions in the system. The first is to manage 44the allocation of unit numbers for device instances and the second is 45to hold the list of device drivers for a particular bus type. 46Each 47.Dv devclass 48has a name and there cannot be two devclasses with the same name. 49This ensures that unique unit numbers are allocated to device 50instances. 51.Sh SEE ALSO | 33.Os FreeBSD 34.Sh NAME 35.Nm devclass 36.Nd object representing a class of devices 37.Sh SYNOPSIS 38.Dv typedef struct devclass *devclass_t; 39.Sh DESCRIPTION 40.Pp 41The 42.Dv devclass 43object has two main functions in the system.
