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".
