Enumeration Type Documentation

enum DDS_PublishModeQosPolicyKind

Kinds of publishing mode.

QoS:

DDS_PublishModeQosPolicy

Enumerator:

DDS_SYNCHRONOUS_PUBLISH_MODE_QOS

Indicates to send data synchronously. If DDS_DataWriterProtocolQosPolicy::push_on_write is DDS_BOOLEAN_TRUE, data is sent immediately in the context of FooDataWriter_write. As data is sent immediately in the context of the user thread, no flow control is applied. See also: DDS_DataWriterProtocolQosPolicy::push_on_write [default] for DDS_DataWriter

DDS_ASYNCHRONOUS_PUBLISH_MODE_QOS

Indicates to send data asynchronously. Configures the DDS_DataWriter to delegate the task of data transmission to a separate publishing thread. The FooDataWriter_write call does not send the data, but instead schedules the data to be sent later by its associated DDS_Publisher. Each DDS_Publisher uses its dedicated publishing thread (DDS_PublisherQos::asynchronous_publisher) to send data for all its asynchronous DataWriters. For each asynchronous DataWriter, the associated DDS_FlowController determines when the publishing thread is allowed to send the data. DDS_DataWriter_wait_for_asynchronous_publishing and DDS_Publisher_wait_for_asynchronous_publishing enable you to determine when the data has actually been sent. Note: DDS_DataWriterProtocolQosPolicy::push_on_write must be TRUE for Asynchronous DataWriters. Otherwise, samples will never be sent. See also: DDS_FlowController DDS_HistoryQosPolicy DDS_DataWriter_wait_for_asynchronous_publishing DDS_Publisher_wait_for_asynchronous_publishing NDDS_Transport_Property_t::gather_send_buffer_count_max
