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