Now I'm trying to make it to work. I start with a perfectly working statement:
proto_tree_add_item(wca_tree, hf_wca_label_2_number, tvb, offset, 4, FALSE);
and transform it to:
proto_tree_add_int(wca_tree, hf_wca_label_2_number, tvb, offset, 4, 26);
When I run it, it troughs an exception: proto.c:2926: failed assertion "DISSECTOR_ASSERT_NOT_REACHED"
What's wrong?
Thanks

Hence if I look on the definition in the epan\proto.h, it requires all the parameters related to the tvb, but no references to the variable itself.
If you look in the declaration in proto.h, you find
/** Add one of FT_INT8, FT_INT16, FT_INT24 or FT_INT32 to a proto_tree.
@param tree the tree to append this item to
@param hfindex field index
@param tvb the tv buffer of the current data
@param start start of data in tvb
@param length length of data in tvb
@param value data to display
@return the newly created item */
extern proto_item *
proto_tree_add_int(proto_tree *tree, int hfindex, tvbuff_t *tvb, gint start,
gint length, gint32 value);
"The variable itself" is the last argument, "value".
