I am looking for sample code to obtain the UUID. Any pointers are greatly
appreciated!
If you're only running on Leopard, one simply way is to use the
new FSEventsCopyUUIDForDevice() function. I suspect that this
was introduced primarily to make it easier to use file system
events, but it's also a convenient method for just obtaining a
volume's UUID.
// Get the device identifier for the given path
struct statfs stat;
NSString* path = [[pathToAnyItemOnVolume
stringByExpandingTildeInPath] stringByStandardizingPath];
if (statfs([[NSFileManager defaultManager]
fileSystemRepresentationWithPath:path],&stat)!=0)
{
NSLog(@"statfs error %d",errno);
return;
}
dev_t device = stat.f_fsid.val[0];
CFUUIDRef uuid = FSEventsCopyUUIDForDevice(device);
CFStringRef uuidStr = CFUUIDCreateString(uuid);
CFRelease(uuid); // CF copy rule
return ((NSString*)uuidStr);
