getRegistryRoot

Declaration

static IORegistryEntry * getRegistryRoot(
 void );

Return Value

A pointer to the IORegistryEntry root instance. It should not be released by the caller.

Overview

This method provides an accessor to the root of the registry for the machine. The root may be passed to a registry iterator when iterating a plane, and contains properties that describe the available planes, and diagnostic information for IOKit. Keys for these properties are in IOKitKeys.h.
