[PD-dev] type of x-lets of an abstraction

[Georg Holzmann]

Hallo devs!

I need to know the in-/outlet type of a pd-oject.
Okay, that's not difficult for externals or internals, but I have 
problems to implement it for abstractions:

(excerpt without all checking: look at "here the problem starts" )

--------8<----------8<--------

//If I have the object
t_object *obj = the_just_created_abstraction;

// get the inlet
t_inlet *in = obj->ob_inlet;

// check if it is an abstraction
t_gobj *canvas = (t_gobj*)obj;
t_symbol *insym = NULL;
if(pd_class(&canvas->g_pd) == canvas_class)
{
     post("is an ABSTRACTION !");

     // get the owner g_obj of the inlet
     t_gobj *next = &in->i_owner->te_g;
     t_object *next_obj = (t_object*)next;

// test: this is working and prints out the name of the abstraction !!
     t_binbuf *b=next_obj->te_binbuf;
     binbuf_print(b);

//--------------------------------
// here the problem starts:

     // I try to get the next object, which
     // should be the obj connected to the inlet ???
     next = next->g_next;
     next_obj = (t_object*)next;

-------8<------------8<---------

and next_obj here is NULL ...

So my question, is next_obj here the object which is connected to the 
abstraction, or should it be the object inside the abstraction which is 
connected to the inlet ...

... hm - now that I wrote that down I think it is unfortunately the 
first case ... so it will be more difficult to get the type ...

Has anyone an idea how to do that (do I have to parse the whole 
abstraction for an inlet object, and get it's x position etc. ...) ?

Thanks for any hints,
LG
