Dictionary with key-value entries specified by sprintf-style syntax (scripting)

Hi,

with the function dictionary_sprintf() I can create a dictionary by specifying a sprintf-style format string with attribute nomenclature (i.e. "@myattrname 100")

For example, given the following values of type A_SYM, A_LONG and A_FLOAT :

t_symbol *sym = gensym("foo");
t_atom_long n = 100;
double f = 3.141592;

I could create a dictionary with the following code:

t_dictionary *dict = dictionary_sprintf("@name %s @intval %ld @floatval %f", sym->s_name, n, f);
if (dict) {
dictionary_dump(dict, 0, 0);
object_free(dict);
}

My question is:
using the same sprintf syntax, is it possible to create a key-value entry of type A_OBJ ?

I really want to do this but it is not working for me:

t_object *obj = someMaxObject;
t_dictionary *dict = dictionary_sprintf("@object %p", obj);
if (dict) {
dictionary_dump(dict, 0, 0);
object_free(dict);
}

Thanks for any assistance.
