2.9. Create Subscriber

A DDS Subscriber contains zero or more DataReaders. A publishing application must create at least one DDS Publisher and then a DataReader for each Topic it wants to subscribe to.

Please refer to SubscriberQos and DataReaderQos for customizable policies for these DDS entities.

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