| * and the message will be removed from the queue. |
| * step: |
| * 1. send two messages to the message queue |
| * 2. call mq_receive() twice, if the two received messages are the same, |
| * which means the first mq_receive does not remove the message from |
| * the queue, the test will fail. Otherwise, the test will pass. |
