I need some advice building a protocol tree. I’m trying to build a tree like this: trb - protocol Label of “TRB Header” trb.version – uint16 trb.format – uint16 trb.scheme_index – uint16 trb.httpd – Boolean type but also introducing a subtree trb.httpd.host – string trb.httpd.identd – string etc. I’m happy with creating the hf_register_info array, the problem I am having is with the various proto_tree_xxx calls. I currently have this: ti = proto_tree_add_item(tree, proto_trb, tvb, 0, -1, ENC_NA); trb_tree = proto_item_add_subtree(ti, ett_trb); tr_header_tree = proto_tree_add_subtree(trb_tree, tvb, tvb_offset, 16, ett_trb_header, NULL, "TRB Header"); /* Add the Version to the tree */ proto_tree_add_item(tr_header_tree, hf_id[0], tvb, tvb_offset, 2, ENC_LITTLE_ENDIAN); tvb_offset += 2; /* Add the Format to the tree */ proto_tree_add_item(tr_header_tree, hf_id[1], tvb, tvb_offset, 2, ENC_LITTLE_ENDIAN); tvb_offset += 2; /* Add the Scheme Index to the tree */ scheme_index = tvb_get_letohs(tvb, tvb_offset); proto_tree_add_item(tr_header_tree, hf_id[2], tvb, tvb_offset, 4, ENC_LITTLE_ENDIAN); tvb_offset += 2; tvb_offset += 2; /* Skip the Reserved field */ tvb_offset += 8; /* Skip the Timestamp */ // ToDo: before processing dsv data we need to add an item for the log data constructed from the protocol name // and the name space e.g. trb.httpd the subtree label should be name_space Log Data e.g. httpd Log Data trb_log_data = proto_tree_add_boolean(trb_tree, hf_id[3], tvb, 0, 0, 1); I’m not sure what I need to do at the end of this block of code to successfully define my trb.httpd subtree. The hf info for the last field is effectively:
What's wrong with proto_tree_add_subtree or proto_tree_add_subtree_format?
{ p_id, { “httpd Log Data”, “trb.httpd”, FT_BOOLEAN, BASE_NONE, NULL, 0x0, "TRUE if TRB in the defined name space", HFILL } } What am I doing wrong?
