Hi,

Sharing part of the relevant code would help answer your question, eg. the proto_add_ calls tested.

Thanks,

Hi all,

I have what I need to add bytes to a tree using proto_tree_add_item or proto_tree_add_bytes. The problem is that I want to customize the name of the proto_item adding a couple of parameters that I know from before. Something like this:

given id = 5 and length = 10, tvb, offset and length. Assuming that for example the bytes are "a05651"

Displayed content should be:

Member (id = 5, len = 10): a05651

However, I can't make it work properly using the _format or _format_value variants. It ends not adding the content of the bytes:

Member (id = 5, len = 10):

Any help?

Thanks,
