31 /* A generalised list. This is deliberately transparent so that you
32 can make the NEXT field of all your chained data structures first,
33 and then cast them to `(SList *)' so that they can be manipulated
34 by this API.
35
36 Alternatively, you can generate raw SList elements using slist_new(),
37 and put the element data in the USERDATA field. Either way you
38 get to manage the memory involved by yourself.
