27 The protocol tree related functions.<BR>
28 A protocol tree will hold all necessary data to display the whole dissected packet.
29 Creating a protocol tree is done in a two stage process:
30 A static part at program startup, and a dynamic part when the dissection with the real packet data is done.<BR>
31 The "static" information is provided by creating a hf_register_info hf[] array, and register it using the
32 proto_register_field_array() function. This is usually done at dissector registering.<BR>
33 The "dynamic" information is added to the protocol tree by calling one of the proto_tree_add_...() functions,
34 e.g. proto_tree_add_bytes().
