 static VALUE 
 setBar(VALUE self, VALUE obj)
 {
     foo *p;
     Data_Get_Struct(self, foo, p);
     p->bar = obj;
     return obj;
 }

 /* ... */

 rb_define_method(Foo, "bar", getBar, 0);
 rb_define_method(Foo, "bar=", setBar, 1);


p.s. : don't forget to have a mark function for your struct and mark p->bar
