95 | * Unsolved problem: if a type is actually a pointer type, like |
96 | * nid_triple is, then its impossible to get a const where you need | |
97 | * it. Consider: | |
98 | * | |
99 | * typedef int nid_triple[3]; | |
100 | * const void *a_; | |
101 | * const nid_triple const *a = a_; | |
102 | * | |
69687aa8 | 103 | * The assignment discards a const because what you really want is: |
babb3798 BL |
104 | * |
105 | * const int const * const *a = a_; | |
106 | * | |
107 | * But if you do that, you lose the fact that a is an array of 3 ints, | |
108 | * which breaks comparison functions. | |
109 | * | |
110 | * Thus we end up having to cast, sadly, or unpack the | |
69687aa8 | 111 | * declarations. Or, as I finally did in this case, declare nid_triple |
babb3798 BL |
112 | * to be a struct, which it should have been in the first place. |
113 | * | |
114 | * Ben, August 2008. | |
115 | * | |
116 | * Also, strictly speaking not all types need be const, but handling | |
117 | * the non-constness means a lot of complication, and in practice | |
118 | * comparison routines do always not touch their arguments. | |
