34.Sh NAME
35.Nm device_get_sysctl_ctx ,
36.Nm device_get_sysctl_tree
37.Nd manipulate the sysctl oid tree for driver specific sysctl nodes
38.Sh SYNOPSIS
39.In sys/param.h
40.In sys/bus.h
41.Ft "struct sysctl_ctx_list *"
42.Fn device_get_sysctl_ctx "device_t dev"
43.Ft "struct sysctl_oid *"
44.Fn device_get_sysctl_tree "device_t dev"
45.Sh DESCRIPTION
46The newbus system automatically adds a sysctl node for each device
47in the system.
48This node can be accessed with the
49.Fn device_get_sysctl_tree
50function.
51The context for the node can be obtained with the
52.Fn device_get_sysctl_ctx
53function.
