+ * Application High Level API for AGL
+ * This function opens "stream".
+ * "stream" means the routing from source to sink.
+ * This function calls registerSource and register the endpoint.
+ * If the endpoint is not registered in AudioManager, Sound Manager uses default value.
+ * audio_role will be translated to "sourceID", and "endpoint_id" will be translated to "sinkID".
+ *
+ * #### Parameters
+ * - audio_role : audio role such like entertainment, emergency.
+ * This name is depends on the system architect.
+ * The name will be application name or will be the group(role) of application.
+ * - endpoint_id : Same as sinkID in Sound Manager.
+ *
+ * #### Return
+ * - error : Error status number. If error is 0, it means the request is accepted, otherwise error message is attached with error code in reply message.
+ * - stream_id : Same as sourceID but the key is different. This is for AHL.
+ * #### Note
