c++ : how to discover any subscribed topics and topics properties name and type

hi
according to documentation, we can find any data writer that able to publish a topic. this ability is possible by subscribing to the "PublicationBuiltinTopicData" topic.
into the "PublicationBuiltinTopicData" topic just we can find topic_name and now we need to find the discovered topic properties name and properties type.
is there any way to access from topic_name to topic_variables?

Connext 5.1.0 problems with Dynamic Data

Hello,

I have a large application that uses the Dynamic Data API and works fine in 5.0.0.  Today I installed RTI Connext DDS 5.1.0.  I recompiled and ran my application against the new libraries and recieve the following error.  Any idea what the problem is?  Screen shot of all error messages attached.  using profile UserQosProfilesLibrary::DefaultProfile, which is also attached.

 First error message is:

RTICdrStream_getBufferLength:!precondition: me->_buffer == ((void *)0)
