Hi,
In
addittion look at the funktion dissect_gsm_map_ISDN_AddressString() ip
packet-gsm_map.c
and
item = get_ber_last_created_item();
subtree =
proto_item_add_subtree(item,
ett_gsm_map_isdn_address_string);
proto_tree_add_item(subtree, hf_gsm_map_extension, parameter_tvb,
0,1,FALSE);
proto_tree_add_item(subtree, hf_gsm_map_nature_of_number,
parameter_tvb, 0,1,FALSE);
proto_tree_add_item(subtree,
hf_gsm_map_number_plan, parameter_tvb, 0,1,FALSE);
digit_str = unpack_digits(parameter_tvb, 1);
proto_tree_add_string(subtree, hf_gsm_map_isdn_address_digits,
parameter_tvb, 1, -1, digit_str);

Hi,
The value used to mach the value string
value is the "masked out" value.
So if the value is 0xc0f0 and the mask is
0xc00 the value used to match the string would be 3.

Ämne: [Wireshark-dev] How to dissect bit
information
Hi Anders/ Steve ,
This is with regards to the mail
posted by vikash How to dissect bit information.
As you have suggested we can get the
desired bit/bits by masking the remaining bits.But the problem we are
facing
is there is a set of values
assosiated with each bit / bits.In Wireshark, the value_string can take values
pertaining to the whole octet
and therefore we are not able to
understand how to capture the values assosiated with bit/bits.
I would really appreciate your help
in this matter
