getRegistryEntryID

Declaration

uint64_t getRegistryEntryID(
 void );

Return Value

An ID for the registry entry, assigned when the entry is first attached in the registry.

Overview

The entry ID returned by getRegistryEntryID can be used to identify a registry entry across all tasks. A registry entry may be looked up by its entry ID by creating a matching dictionary with IORegistryEntryIDMatching() in user space, or IOService::registryEntryIDMatching() in the kernel, to be used with the IOKit matching functions. The ID is valid only until the machine reboots.
