Thanks everyone.
The inlet_new(…) method of dispatching a bang to a bang2 t_symbol works
great. I had to change the class_addmethod a little from the x_time.c example.
Not sure why on my build I have to add a t_atomtype (instead of just
terminating with a 0) as an argument but this is what I did and it works:
class_addmethod(mynamo_class, (t_method)mynamo_generate, gensym("bang2"),
A_NULL, 0);
Not sure if the A_NULL is allocating memory somewhere, or passing a dummy
value to my function but I don't see any errors or leaks. If I see anything
I'll report back.
I also really like the dummy class method used in the [list] family. I'll
try that too at some point.
Much appreciated,
Rob
