thank you very much Justin
the following code does the job
{
const char *computerSerialNumber = NULL;
CFTypeRef CFComputerSerialNumber = NULL;
io_object_t ioEntry;
io_iterator_t ioIterator;
kern_return_t kernResult;
mach_port_t masterPort;
kernResult = IOMasterPort(MACH_PORT_NULL, &masterPort);
if(kernResult == KERN_SUCCESS)
{
kernResult = IORegistryCreateIterator
(masterPort,kIOServicePlane,0,&ioIterator);
}
if(kernResult == KERN_SUCCESS)
{
ioEntry = IOIteratorNext(ioIterator);
if(ioEntry != 0)
{
CFComputerSerialNumber =
IORegistryEntrySearchCFProperty(ioEntry,kIOServicePlane,CFSTR
(kIOPlatformSerialNumberKey),kCFAllocatorDefault,0);
IOObjectRelease(ioEntry);
}
IOObjectRelease(ioIterator);
}
if(CFComputerSerialNumber != NULL)
{
if(CFStringGetTypeID() == CFGetTypeID
(CFComputerSerialNumber))
{
computerSerialNumber = CFStringGetCStringPtr
((CFStringRef)CFComputerSerialNumber,kCFStringEncodingMacRoman);
}
CFRelease(CFComputerSerialNumber);
}
if(computerSerialNumber != NULL) printf("Serial Number: %
s\n",computerSerialNumber);
}
however I suppose that there is a more elegant way by using some
matching facility

Hi
is it possible to access PROM data?
specifically we need to obtain computer's serial number
thanks
I don't know how to do that, but 'ioreg -l' will show you the
system's serial number (IOPlatformSerialNumber). Digging through
the source may help; I took a quick look (IOKitTools project), but
nothing said "here I am" ;-/
Regards,
Justin
