How to extract data from an XCDR recorded file?

Hi,  

I was wondering if there's a way I can extract a sample (for example first and last sample) from an XCDR log file generated using the Recording Service?

I understand this can be done if I use the Converter service and convert my log file into JSON format. However I'm using rather large data, and the process of converting the whole log file will take significant time when I just need to extract a few samples from that file.

RTI Connext Micro unique API and QoS

I am evaluating microDDS and am looking for a description of some of the micro DDS unique API's used in some of the examples provided with micro DDS.  These APIs are not described in the "RTI Connext Micro API and QoS Guide".  Specifically, in the HelloWorld_dpde example:

1. Configuration of the registry via RT_Registry_register()  for strings "wh", "rh",  "_udp" and  "dpde" strings.  What is the purpose of this function call and what is the signficance of the strings?
