{
OSString * separator = OSString::withCStringNoCopy(".");
OSArray * array = OSArray::withCapacity(10);
char devicePath[512];
bzero(devicePath, sizeof(devicePath));
IOACPIPlatformDevice * parent = acpiDevice;
IORegistryIterator * iter = IORegistryIterator::iterateOver(acpiDevice, gIOACPIPlane, kIORegistryIterateParents | kIORegistryIterateRecursively);
if (iter)
{
do {
