[PD-dev] help coding an object, I need it cause I don't know better

[Alexandre Torres Porres]

Ok, updated the code as before, so it compiles
https://github.com/porres/pd-else/commit/4f052fbe4af3889f06eb69c236f04eeae3555485

now I initialize as  **x_fval in
https://github.com/porres/pd-else/blob/master/Code_source/Compiled/control/var.c#L17

At bangs, I get and set the value of the output atom list as
*SETFLOAT(at+i, ***x->x_fval[i]);*
https://github.com/porres/pd-else/blob/master/Code_source/Compiled/control/var.c#L27

In the list method, I get atoms' values with **x->x_fval[i] =
atom_getfloat(av+i); *
https://github.com/porres/pd-else/blob/master/Code_source/Compiled/control/var.c#L36

What's weird to me is now that in the 'new' method, I initialize the
variable as

*x->x_fval[i] = var_get(x->x_sym[i] = atom_getsymbol(av+i)); *
https://github.com/porres/pd-else/blob/master/Code_source/Compiled/control/var.c#L80C9-L80C68

and it works, and no need of '*' in here.. I would expect it though... not
sure why, just feels right :)

But i am just making sure now that all is ok and that my bugs are
elsewhere. Also note I am initializing the data as x->x_fval =
getbytes(sizeof(float) * x->x_n); in
https://github.com/porres/pd-else/blob/master/Code_source/Compiled/control/var.c#L76
and I free it as freebytes(x->x_fval, x->x_n * sizeof(*x->x_fval)); in
https://github.com/porres/pd-else/blob/master/Code_source/Compiled/control/var.c#L40C5-L40C55

thanks
