Macro Definition Documentation

#define DDS_PUBLICATION_PRIORITY_UNDEFINED

Initializer value for DDS_PublishModeQosPolicy::priority.

When assigned this value, the publication priority of the data writer will be set to the lowest possible value.

#define DDS_PUBLICATION_PRIORITY_AUTOMATIC

Constant value for DDS_PublishModeQosPolicy::priority.

When assigned this value the publication priority of the data writer will be set to the largest priority value of any sample currently queued for publication by the data writer or data writer channel.


Enumeration Type Documentation

Kinds of publishing mode.

QoS:
DDS_PublishModeQosPolicy
Enumerator:
DDS_SYNCHRONOUS_PUBLISH_MODE_QOS 

Indicates to send data synchronously.

Data is sent immediately in the context of the user thread, no flow control is applied.

DDS_ASYNCHRONOUS_PUBLISH_MODE_QOS 

Indicates to send data asynchronously.

Configures the DDS_DataWriter to delegate the task of data transmission to a separate thread. The FooDataWriter_write call does not send the data, but instead schedules the data to be sent later.

DDS_FlowController
DDS_HistoryQosPolicy
DDS_AUTOMATIC_PUBLISH_MODE_QOS 

Automatically configures the publishing mode.

Configures the DDS_DataWriter to automatically determine how data transmission is performed. If the minimum data size required for the serialized type requires fragmentation, then data is handled in the DDS_ASYNCHRONOUS_PUBLISH_MODE_QOS mode.

If the minimum data size does not require fragmentation, then data is sent in the DDS_SYNCHRONOUS_PUBLISH_MODE_QOS mode.
