queue

rt_mq_t data_service_config_tag::queue

If it's NULL, the service shares the system queue and thread. If it's not NULL, the message would be posted to this queue, so service should create its own thread and retrieve message from this queue. For simlicity the user created thread could use data_service_entry as thread entry and pass the queue as thread's parameter, such as rt_thread_init(&thread_handle, "test", data_service_entry, queue, thread_stack, sizeof(thread_stack), 25, 10);
