A C-string path.
A handle to the IORegistryEntry witch was found with the path, to be released with IOObjectRelease by the caller, or MACH_PORT_NULL on failure.
This function parses paths to lookup registry entries. The path should begin with '<plane name>:' If there are characters remaining unparsed after an entry has been looked up, this is considered an invalid lookup. Paths are further documented in IORegistryEntry.h
