Hi, I've got a bunch of statically entered entries for the "normal" way of registering the field array:

 

I.e.

 

using static hf_register_info hf[] = {
...}

 

proto_register_field_array(proto_ublox, hf, array_length(hf));

 

Now I have chunk of code were I want to do this:

 

#define    NUM_PORT_VALS    (6)

#define    NUM_PROTO_VALS    (8)

 

static int hf_mon_msgpp_msg[NUM_PORT_VALS][NUM_PROTO_VALS];

 

...

 

    for (i = 0; i < NUM_PORT_VALS; i++)
    {
        subtree =
            proto_tree_add_subtree_format(tree, tvb, curr_offset, 16,
                ett_mon_msgpp_msg[i], NULL,
                "msg%u - Number of successfully parsed messages for each protocol on port%u",
                i + 1, i);

 

        for (j = 0; j < NUM_PROTO_VALS; j++)
        {
            proto_tree_add_item(subtree, hf_mon_msgpp_msg[i][j], tvb, curr_offset, 2, ENC_LITTLE_ENDIAN);
            curr_offset += 2;
        }
    }

Is there a way to append or the 48 (6 x 8) hf_register_info elements that I will generate at startup?

 

I would allocate something like this:

 

static hf_register_info hf2[NUM_PORT_VALS * NUM_PROTO_VALS];

 

And then programatically build the field name, description, etc.

 

for port < NUM_PORT_VALS ...

for proto < NUM_PROTO_VALS ...

        { &hf_mon_msgpp_msg[port][proto],

...
           "ublox.mon.msgpp.parsed.port%u.proto%u", port, proto)

 

Finally appending these field entries?

 

I looked through proto.h/proto.c but I couldn't find what I was looking for.

 

Thanks for any help

 

Cheers
