My first one would be: how do I get the header_field_info structure
instance from its structure id? Here is what I'm trying to achieve:
static int hf_instr_id = -1;
[...]
{ &hf_instr_id,
{ "Instrument Identifier", "my_proto.instr_id", FT_UINT64,
BASE_DEC, NULL, 0x00,
"[...]", HFILL }
},
[...]
ptvcursor_add(cursor, hf_instr_id, 8, ENC_LITTLE_ENDIAN);
In the line just above I'd like to replace the length (which is 8) by
something roughly looking like that:
int len = ftype_len(gap_hfinfo.hfi[xxx]->type);
ptvcursor_add(cursor, hf_instr_id, len, ENC_LITTLE_ENDIAN);
One of my issue is that gap_hfinfo array (which contains all the
header_fields_info instances) is static to the proto.c file. And I
find no accessors to it.
Is there an actual way that I've overlooked?
/** Get the header_field information based upon a field or protocol id.
@param hfindex item # n (0-indexed)
@return the registered item */
WS_DLL_PUBLIC header_field_info* proto_registrar_get_nth(guint hfindex);
btw. there is also a proto_registrar_get_length() function,
which do what you want (ftype_len(...)->type).
Cheers,
Jakub.
