Question: I know that you can use [embed.ly](http://embed.ly) to test your oEmbed provider service, but do you know any other services where you can test [oEmbed discovery](http://oembed.com/#section4)?

I want to make sure that oEmbed-enabled consumers can correctly tap into my oEmbed provider, but I couldn't find a way to do so.

Any help or advice is appreciated.

Answer: 
Try:

```
queue<int> *my_queue = (queue<int> *)Ptr ;
my_queue->push(byte) ;

pthread_create(&thread, NULL, &AddPacket, (void*)&queue) ; 

```

.. something along those lines, anyway
You try to cast object type to pointer type. It is not allowed. I guess you are new to C++, so I post corrected code here to unpuzzle you and get you going, but please read a book on C++:

```
queue<int>* my_queue = (queue<int>*)Ptr ; 
my_queue->push(byte) ;

pthread_create(&thread, NULL, &AddPacket, &queue) ; 

```

Remember to read about pointers on C++ :)
