Fake-field-Wrapper

Question

Dears, I have a question, I want to understand the meaning of this message "fake-field-wrapper", in what situation is used, where can I get or if you can share more documentation related to this message?

Answer 1

For reference the context appears to be when using PDML output.

The comment next to the code that outputs the <proto name="fake-field-wrapper""> element is:

/* Will wrap up top-level field items inside a fake protocol wrapper to preserve the PDML schema */

and the code that checks if this is necessary is:

wrap_in_fake_protocol =
    (((fi->hfinfo->type != FT_PROTOCOL) ||
      (fi->hfinfo->id == proto_data)) &&
     (pdata->level == 0));

I'm guessing this means that if the top-level node isn't of type FT_PROTOCOL or just data then the fake-field-wrapper node is printed.

I'd need to see a capture to work out what's really happening.
