I noticed that they don't return pointers when created, but actual objects. So to get a pointer, I'm trying to declare it like this:

```
dispatch_queue_t* queue;
*queue = dispatch_queue_create("double_buffer_protection_queue", DISPATCH_QUEUE_SERIAL);

```

The C++ programmer in me says that should work, but it gives a BAD\_ACCESS error, so I'm guessing I'm approaching this the wrong way. 

If I want a serial queue that can be accessed by any object in my program, how do I do it? The code I showed above was meant to go in the AppDelegate class.
