Hello Ronnie,
Thanks for your help.
My application is a simple tool that receives the protocol name and raw
data via the standard input, passes them to libwireshark and writes the
decoded message tree in XML form to the standard output.
The tool is not published yet, and no description is available at the
moment, but we will publish it soon.
