QoS properties for controlling Dynamic Data resources

Hello,

I have an application that is using DDS Dynamic Data API's to read a DDS Topic with a large payload.  I get the following error when the payload is above about 32K bytes.  Are there QoS properties I can adjust to support larger topic types?

 

DDS_DynamicData_copy:unable to grow buffer

PRESPsReaderQueue_readOrTakeNextSample:!copy

PRESPsReader_takeNextSample:!queue takeNextSample

 

Thanks.

Mark.

Hi Mark,

It looks like you will need to increase DynamicDataProperty_t::max_buffer_size. Here is example code:

DDS.DynamicDataProperty_t property = DDS.DynamicData.DYNAMIC_DATA_PROPERTY_DEFAULT; property.buffer_max_size = 0x3fffffff; _theInstance = new DDS.DynamicData(typeCode, property);

Regards,

Bobby

That worked.  Thanks for your help.
