[PD-dev] post fiddle~ processing -1

[marc bohlen]

hi list

I would like to postprocess the output of fiddle~ pitch data in a separate external PD object. (I want to find the distribution of the resultant frequencies, so I can make an estimation of its origin [voice vs whistle, for example]). 

New to PD external creation, I imagine something like tabwrite would be able to access the data (from fiddle~) in the garray datastructure 
(a->x_array->vec[n]) from where I could process it. 

Any suggestions?


Aside:
I have a silly linker issue with  ‘findbyclass’:

With this declaration
EXTERN t_pd *pd_findbyclass(t_symbol *s, t_class *c);
t_garray *a = (t_garray *) pd_findbyclass(x->x_arrayname,garray_class); 

creates an “unresolved external (_garray_class)” linker error on win2k VC++. 
Tried gensym to create a symbol (“garray”, “struct”, even “class”). No luck

BUT this is just fine:
EXTERN t_pd *pd_new(t_class *cls);
t_counter *x = (t_counter *)pd_new(counter_class);	 

What is special with garray_class (or what am I blind to)?

Thanks! marc
