No, outlet structs are only to be produced by the outlet constructor,
called outlet_new(). It must be called with a t_object argument, and a
type specifier symbol.

You must use pointers to refer to outlets.

In my code I have something like this that does automatic generation of
a variable number of outlets for all of my objects:

	self->bself->out = new t_outlet*[noutlets];
	for (int i=0; i<noutlets; i++) {
		self->bself->out[i] = outlet_new(self->bself,&s_anything);
	}

self->bself is a BFObject, subclass of t_outlet.
self->bself->out is a t_outlet **.
