/*-
|
|
* Unsolved problem: if a type is actually a pointer type, like
|
|
* nid_triple is, then its impossible to get a const where you need
|
|
* it. Consider:
|
|
*
|
|
* typedef int nid_triple[3];
|
|
* const void *a_;
|
|
* const nid_triple const *a = a_;
|
|
*
|
|
* The assignment discards a const because what you really want is:
|
|
*
|
|
* const int const * const *a = a_;
|
|
*
|
|
* But if you do that, you lose the fact that a is an array of 3 ints,
|
|
* which breaks comparison functions.
|
|
*
|
|
* Thus we end up having to cast, sadly, or unpack the
|
|
* declarations. Or, as I finally did in this case, declare nid_triple
|
|
* to be a struct, which it should have been in the first place.
|
|
*
|
|
* Ben, August 2008.
|
|
*
|
|
* Also, strictly speaking not all types need be const, but handling
|
|
* the non-constness means a lot of complication, and in practice
|
|
* comparison routines do always not touch their arguments.
