[PD-dev] FIXED problem defining t_outlet array

[Brian Sheehan]

Thanks Mathieu, that worked. Is it so that we never
have to worry about deallocating memory that
outlet_new is the only way of creating t_outlet
structs?

For the record, this what my code now looks like:

typedef struct _shapetape
{
    t_object x_obj;
    t_clock *x_clock;
    double x_deltime;
    int x_hit;
    t_int points;
    t_outlet *outlets[NUM_OUTLETS];
    double *x, *y, *z, *q1, *q2, *q3, *q4;
    t_atom *x_out, *y_out, *z_out, *q1_out, *q2_out,
*q3_out, *q4_out; 
} t_shapetape;

To create the outlets:

for (i = 0; i < NUM_OUTLETS; i++)
{
    x->outlets[i] = outlet_new(&x->x_obj,&s_list);
}

To write to outlets:

for (i = NUM_OUTLETS - 1; i >=0; i--)
{
    outlet_list(x->outlets[i],
                &s_list,
                size,
                vector[i]);
}
