43 * Definitions for sysctl call. The sysctl call uses a hierarchical name
44 * for objects that can be examined or modified. The name is expressed as
45 * a sequence of integers. Like a file path name, the meaning of each
46 * component depends on its place in the hierarchy. The top-level and kern
47 * identifiers are defined here, and other identifiers are defined in the
48 * respective subsystem header files.
51 #define CTL_MAXNAME 24 /* largest number of components supported */
54 * Each subsystem defined by sysctl defines a list of variables
55 * for that subsystem. Each name is either a node with further
56 * levels defined below it, or it is a leaf of some particular
57 * type given below. Each sysctl level defines a set of name/type
58 * pairs to be used by sysctl(8) in manipulating the subsystem.
