4.8. Create Subscriber

A subscribing application needs to create a DDS Subscriber and then a DataReader for each Topic to which it wants to subscribe.

In Connext Micro, SubscriberQos in general contains no policies that need to be customized, while DataReaderQos does contain several customizable policies.

DDS_Subscriber *subscriber = NULL;
subscriber = DDS_DomainParticipant_create_subscriber(participant,
                                                     &DDS_SUBSCRIBER_QOS_DEFAULT,
                                                     NULL,
                                                     DDS_STATUS_MASK_NONE);
if (subscriber == NULL)
{
    /* failure */
}
