Apologies for that, this is the yahoo web client which sometimes switches back from plain text to HTML. Below here I re-pasted the original email (hopefully will show up nicely now).

Anyhow, I rolled my own implementation of it, see lines 362-531 below:

Feedback welcome!

Hello, I am trying to implement a threaded equivalent of outlet_list(), which recursively copies the content of a list (symbol, argc, argv) into a ringbuffer at one end (worker thread) and retrieves them at the other end (audio thread). I have been looking through the Pd source code in and out but could not find a suitable function, except perhaps for those implemented in the [list] class, but they are not meant to be accessible from outside (static!). What is the best way of doing this? Thanks

For reference, here is some code: ---------------- a) this is the (working!) ringbuffer implementation I have for outlet_float:

struct t_outletrb_float_msg {       t_outlet* outlet;       t_float f;   };

// call this from the audio thread   void outletrb_floatprocess(ring_buffer* rb)   {       while(rb_available_to_read(rb) > sizeof(struct t_outletrb_float_msg))       {           struct t_outletrb_float_msg msg;           rb_read_from_buffer(rb, (char*)&msg, sizeof(msg));           t_outlet* x = msg.outlet;           t_float f = msg.f;           outlet_float(x, f);       }   }

// call this from the worker thread void outletrb_float(ring_buffer* rb, t_outlet *x, t_float f)   {       struct t_outletrb_float_msg msg;       msg.outlet = x;       msg.f = f;       rb_write_to_buffer(rb, 1, (char*)&msg, sizeof(msg));   }

------------------- b) and this is the INCOMPLETE ringbuffer implementation of outlet_list:

struct t_outletrb_list_msg {       t_outlet* outlet;       t_symbol* s;       int argc;       t_atom* argv;   } // call this from the audio thread   void outletrb_listprocess(ring_buffer* rb)   { ///// retrieve the data from rb and use them for outlet_list();   }

// call this from the worker thread   void outletrb_list(ring_buffer* rb, t_outlet *x, t_symbol *s, int argc, t_atom *argv)   { //??????? this is the function I am trying to figure out   }
