Asynchronous and Synchronous

Hello,

 

I have a question regarding QoS default value inconsistency.

Why the default value of the Asynchronous Publisher is "Asynchronous" where the default value of the Publish Mode is "Synchronous"?

Which QoS policy has higher priority than the other one?

 

Thanks

Hello,

 

Even though the asynchronous publisher QoS is enabled by default, the threads associated with the asynch publisher are not spawned until the first DataWriter that has Publish_Mode set to DDS_ASYNCHRONOUS_PUBLISHER_MODE_QOS is enabled. 

 

So it is not really a not a prioritization question. They both have to be enabled to use asynchronous publishing.

 

Best Regards,

 

Bobby
