Hi,
one question I'd like u to clear out : )

Supposing we have a piece of code like this:

if (XXX_tree) {

value = tvb_get_ntohl (tvb, offset);

g_hash_table_insert (table, key, GINT_TO_POINTER(value));

...

}
Now, if XXX_tree == NULL (that is, the user has not asked for a detailed dissection), will 'value' not be inserted into the hash table? if so, how should I avoid including the code 

value = tvb_get_ntohl (tvb, offset);

g_hash_table_insert (table, key, GINT_TO_POINTER(value));

inside a control structure like 'if (XXX_tree)' ?
