I'm a little bit confused with a newbie pointer problem...If i send a 

void myobj_mode(t_myobj *x, Symbol *s, int ac, Atom *av)

outlet_list(x->m_ob.o_outlet,ps_list,3,list);

it doesn't output '1 1 1' but '1240418 1240424 1240430'... why ?

I'm a little bit confused with a newbie pointer problem...If i send a 
message "mode 1 1 1" to this :

void myobj_mode(t_myobj *x, Symbol *s, int ac, Atom *av)
{
    if (ac==3)
    {
        t_atom list[3];            
        SETLONG(list+0, av);
        SETLONG(list+1, av+1);
        SETLONG(list+2, av+2);
        outlet_list(x->m_ob.o_outlet,ps_list,3,list);
    }

Because you want to set a LONG but set the t_atom as value... so you end 

up with the stuff at the address of av+i being represented as long...

In case you're sure to get ints only, you can copy input t_atoms to 

output t_atoms directly, otherwise check for ints first (av[i].a_type == 

A_LOMG) and access the int value using av[i].a_w.w_long. So in the end

it should read:

SETLONG() assumes it is being passed a long integer, but av is an 

*atom* pointer. If you want the long from within the atom pointer you 

need to retrieve it somehow. e.g... av->a_w.w_long, or atom_getlong(av);

Or you could just copy the atoms directly, e.g. list[0] = av[0];

*atom* pointer. If you want the long from within the atom pointer you  
need to retrieve it somehow. e.g... av->a_w.w_long, or atom_getlong(av);
