Wireshark-dev: [Wireshark-dev] Adding an item to the proto tree for which there is no associate

Hi folks,

I am trying to indicate that a particular procedure (like the NULL
proc) has no parameter or no response value.

I was trying to add the string "void" using proto_tree_add_none_format
but this is not inserting anything into the tree.

For example:

        tmp_item = proto_tree_add_none_format(tree, hf_void, tvb,
offset, 0, "void");
        PROTO_ITEM_SET_GENERATED(tmp_item);

I was then expecting to see something like (because this is an RPC
sub-dissector):

    [Program Version: 3]
    [V3 Procedure: SOME_PROC_NAME (4)]
    void

However, the void is not showing up. What am I doing wrong?
