{
 * Definitions for sysctl call.  The sysctl call uses a hierarchical name
 * for objects that can be examined or modified.  The name is expressed as
 * a sequence of integers.  Like a file path name, the meaning of each
 * component depends on its place in the hierarchy.  The top-level and kern
 * identifiers are defined here, and other identifiers are defined in the
 * respective subsystem header files.
}

{
 * Each subsystem defined by sysctl defines a list of variables
 * for that subsystem. Each name is either a node with further
 * levels defined below it, or it is a leaf of some particular
 * type given below. Each sysctl level defines a set of name/type
 * pairs to be used by sysctl(1) in manipulating the subsystem.
