244 * rune_t is declared to be an ``int'' instead of the more natural
245 * ``unsigned long'' or ``long''. Two things are happening here. It is not
246 * unsigned so that EOF (-1) can be naturally assigned to it and used. Also,
247 * it looks like 10646 will be a 31 bit standard. This means that if your
248 * ints cannot hold 32 bits, you will be in trouble. The reason an int was
249 * chosen over a long is that the is*() and to*() routines take ints (says
250 * ANSI C), but they use __ct_rune_t instead of int.
252 * NOTE: rune_t is not covered by ANSI nor other standards, and should not
253 * be instantiated outside of lib/libc/locale. Use wchar_t. wint_t and
254 * rune_t must be the same type. Also, wint_t should be able to hold all
255 * members of the largest character set plus one extra value (WEOF), and
256 * must be at least 16 bits.
