72 * char version[COLLATE_STR_LEN]; // must be COLLATE_VERSION
73 * collate_info_t info; // see below, includes padding
74 * collate_char_pri_t char_data[256]; // 8 bit char values
75 * collate_subst_t subst[*]; // 0 or more substitutions
76 * collate_chain_pri_t chains[*]; // 0 or more chains
77 * collate_large_pri_t large[*]; // extended char priorities
79 * Note that all structures must be 32-bit aligned, as each structure
80 * contains 32-bit member fields. The entire file is mmap'd, so its
81 * critical that alignment be observed. It is not generally safe to
82 * use any 64-bit values in the structures.
