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 ? I'm asking that because I'm rewriting a pix_openni2 object and to free the openni context i have to call a shutdown() function on quit and not on object deletion

Hello all,
While reorganizing my code a question about memory management in Pd arose in me. If I allocate memory within the constructor space, do I have to
free
this myself?
yes
If yes, how or where should I do this?
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, ...); }
Do I have to worry about this or is all memory freed automatically when
an
object is removed from its canvas?
no magic is involved, thus you have to take care yourselves.
