DEVICE_GET_SYSCTL(9)   FreeBSD Kernel Developer's Manual  DEVICE_GET_SYSCTL(9)

NAME
     device_get_sysctl_ctx, device_get_sysctl_tree - manipulate the sysctl oid
     tree for driver specific sysctl nodes

SYNOPSIS
     #include <sys/param.h>
     #include <sys/bus.h>

     struct sysctl_ctx_list *
     device_get_sysctl_ctx(device_t dev);

     struct sysctl_oid *
     device_get_sysctl_tree(device_t dev);

DESCRIPTION
     The newbus system automatically adds a sysctl node for each device in the
     system.  This node can be accessed with the device_get_sysctl_tree()
     function.  The context for the node can be obtained with the
     device_get_sysctl_ctx() function.
