Sure, as declared in epan/proto.h.

I mean this:

 proto_tree * my_tree;
 const gchar *my_string;
 /* ... */
 my_tree =  ptvcursor_add_text_with_subtree(cursor, .....,  "foo");
 /* ...do some more decoding, including some ptvcursor_add()... */
 /* now I know which text to place there instead of "foo": */
 my_string = val_to_str(...);
 proto_item_set_text(my_tree, "<%s>", my_string);

The last line compiles and runs without runtime errors, and the text of 
the node created by ptvcursor_add_text_with_subtree() changes from "foo" 
to "<" + my_string + ">".

Nothing. I just have no proto_item* to pass, since 
ptvcursor_add_text_with_subtree() doesn't return any.
