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