Not exactly what you are asking for but you could try this:
(dissecting and displaying the top 12 bits of a 16 bit integer in a
somewhat binary representation)
{ &hf_foo,
{"Foo", "foo.foo", FT_UINT16, BASE_HEX, NULL, 0xfff0, "something", HFILL }},
I.e specifying a bitmask which will make ethereal decode it and display it as
XXXX XXXX XXXX ....
Probably not exactly what you want but maybe close enough?

Hi,
I'm developping an Ethereal plugin to add a dissector for a protocol.
This protocol has a field Mask that I would like to display in binary e.g.
Mask : 1100 1011 1010
But I can't find the solution that allows such a thing :
In proto.c, one have :
/** radix for decimal values, used in header_field_info.display */
typedef enum {
BASE_NONE, /**< none */
BASE_DEC, /**< decimal */
BASE_HEX, /**< hexadecimal */
BASE_OCT, /**< octal */
BASE_DEC_HEX, /**< decimal (hexadecimal) */
BASE_HEX_DEC /**< hexadecimal (decimal) */
} base_display_e;
But there is no BASE_BIN for example, in order to insert into (e.g.):
static hf_register_info hf[] = {
{ &hf_foo_pdu_type,
{ "FOO PDU Type","foo.type",
FT_UINT8, BASE_DEC, NULL, 0x0,
"", HFILL }
},
};
Has someone a solution for this problem without I have to modify ethereal
source code and rebuild it ?
