Wireshark · Wireshark-dev: Re: [Wireshark-dev] dissector array display handling

["Manthos S." <s.manthos@xxxxxxxxx>]

Hello all, 

i dont think it somthing terrible what i am asking for. I just want to know which are the right expressions of "field_name" and "value" in the following function:

proto_tree_add_bytes_format(pal_dl_DataList_subtree, hf_pal_dataLength, tvb, offset, 4, dataLength, "%d: [ %s : %s , ", i, field_name, value );


Any ideas?
Have a nice day!

Dear experts,

Thank you all for your answers, they have been very helpful for me to understand a bit more the wireshark logik.

I am a step forward and i need some more easy help.

I managed the loop for displaying the array content properly.
Instead of using the simple proto_tree_add_item() i am using now the proto_tree_add_bytes_format(), in order to be able to add brackets, index numbers etc. in my gui tree. (i hope *_bytes_* is the right one)
My question is:
How can i add in the printf part of the proto_tree_add_bytes_format() the name of the field and the value. In which structure are these infos saved? I need something like that or similar (????):

proto_tree_add_bytes_format(pal_dl_DataList_subtree, hf_pal_dataLength, tvb, offset, 4, dataLength, "%d: [ %s : %s , ", i, field_name, value );

With the proto_tree_add_bytes_format_value() the name of the field is added automaticaly, according DEVELOPER.readme. But i want to insert the index number in front of the name, so i have to use proto_tree_add_bytes_format().

My aim is to achieve a gui presence like this:

+ array_name
     index1:[ FieldName : Value ,
                    FieldName : Value ,
                    FieldName : Value ,
                    ...                               ]
     index2:[ FieldName : Value ,
                    FieldName : Value ,
                    FieldName : Value ,
                    ...                               ]

etc.



Looking forward to get youranswers.
Cheers

ps. to answers your question, i am developing a dissector for an lower layer interface for LTE defined from FemtoForum.
