Re: [PD-dev] Destructor in external classes
oops in fact cleanup with free method doesn't work because it's not called on quit but only on object deletion, so the atexit() seems to be the key thanks kjetil + a -- do it yourself http://antoine.villeret.free.fr 2014-03-25 16:01 GMT+01:00 Antoine Villeret antoine.ville...@gmail.com: for now the OpenNI init() function is called from obj_setupCallback which is called only once and if I call shutdown() I need to recall init() on new instance creation so yes it could be a workaround but having a onQuit() method will make my work easier :-) + a -- do it yourself http://antoine.villeret.free.fr 2014-03-25 15:50 GMT+01:00 Dan Wilcox danomat...@gmail.com: On Mar 25, 2014, at 6:00 AM, pd-dev-requ...@iem.at wrote: *From: *Kjetil Matheussen k.s.matheus...@gmail.com *Subject: **Re: [PD-dev] Destructor in external classes* *Date: *March 24, 2014 at 12:32:00 PM CDT *To: *Antoine Villeret antoine.ville...@gmail.com *Cc: *IOhannes m zmölnig zmoel...@iem.at, pd-dev List pd-dev@iem.at *Reply-To: *k.s.matheus...@notam02.no On Mon, Mar 24, 2014 at 2:56 PM, Antoine Villeret antoine.ville...@gmail.com wrote: hello, the free method seems to be called when the object is deleted from the canvas. is there a similar method called on Pd quit ?

Re: [PD-dev] Destructor in external classes
this patch is quite old, and seems to be included in Pd-extended since about 2 years, is there still a good reason to not include this patch in pd-vanilla ? thanks anyway to point me there regards antoine -- do it yourself http://antoine.villeret.free.fr 2014-03-24 14:58 GMT+01:00 IOhannes m zmölnig zmoel...@iem.at: On 03/24/2014 02:56 PM, Antoine Villeret wrote: hello, the free method seems to be called when the object is deleted from the canvas. is there a similar method called on Pd quit ? no. see http://sourceforge.net/p/pure-data/patches/82/ fgsdr IOhannes ___ Pd-dev mailing list Pd-dev@iem.at http://lists.puredata.info/listinfo/pd-dev ___ Pd-dev mailing list Pd-dev@iem.at http://lists.puredata.info/listinfo/pd-dev

Hello IOhannes,
On Mon, Mar 24, 2014 at 2:45 PM, IOhannes m zmölnig zmoel...@iem.at wrote:
the destructor is called free_method in Pd-lingo and is set via
class_new() [1].
so you basically would do:
void myclass_free(t_myclass*x) {
free(x-x_ptr);
}
// ...
void myclass_setup(void) {
class_new(gensym(myclass), myclass_new, myclass_free,
sizeof(t_myclass), 0, ...);
}
Thanks! I now see how it works. You indeed mentioned it in the tutorial.
Sorry for missing that part.
Regards.
