And in addition to this, only those structs that have extra items that are stored
in memory.  For example, if you CREATE more than just one structure.....

struct char_data {
  struct blah_data *blah;

CREATE(ch, struct char_data, 1);
CREATE(ch->blah, struct blah_data, 1);

You would need to reverse the creation order and free blah first, then ch.


Hope this helps :)
