Friedrich is still having a problem:
Hi Didier,

Yes, the second one looks well since that API has more information.

I am still working on version 1.3.1 and version 1.5.1 , so could you
please provide a method or API for that? I guess something that has the
following flavor would work for me. Of course, I believe your real codes
will be much more complicated with all error protections :-). I will put
it into the rohc_comp.c file at my end. Thanks!

	{

	/* return the length of the feedback header/data,

	return feedback_length;
